Perkembangan Arsitektur 1


ARSITEKTONIK

Architectonic berasal dari bahasa yunani arkhitektonikos adalah (Arsitektur) seni dan ilmu merancang bangunan dan struktur fisik lainnya. Arsitektur adalah baik proses dan produk perencanaan, merancang dan membangun ruang yang mencerminkan fungsional, sosial, dan pertimbangan estetika. Ini memerlukan manipulasi dan koordinasi dari bahan, teknologi, cahaya, dan bayangan. Arsitektur juga mencakup aspek-aspek pragmatis menyadari dirancang ruang, seperti perencanaan proyek, dan konstruksi memperkirakan biaya administrasi. Sebuah definisi yang lebih luas dapat meliputi semua kegiatan desain dari tingkat makro (desain perkotaan, arsitektur lansekap) ke level mikro (detail konstruksi dan furnitur). Pada kenyataannya, arsitektur saat ini dapat merujuk kepada aktivitas merancang sistem apapun dan sering digunakan dalam dunia TI. Karya arsitektur sering dianggap sebagai simbol politik dan budaya dan sebagai karya seni. Sejarah peradaban sering diidentikkan dengan arsitektur yang masih hidup prestasi mereka. Rencana arsitek, desain dan meninjau pembangunan gedung dan struktur untuk penggunaan orang-orang yang oleh organisasi kreatif bahan dan komponen dengan pertimbangan kepada massa, ruang, bentuk, volume, tekstur, struktur, cahaya, bayangan, materi, program, dan pragmatis unsur-unsur seperti biaya, keterbatasan konstruksi dan teknologi, untuk mencapai suatu tujuan yang biasanya fungsional, ekonomis, praktis dan sering artistik. Inilah yang membedakan dari teknik desain arsitektur, yang memiliki sebagai objek utama manipulasi kreatif bahan dan bentuk menggunakan matematika dan prinsip-prinsip ilmiah. Sebagai dokumentasi yang dihasilkan oleh arsitek, biasanya gambar, rencana dan spesifikasi teknik, arsitektur mendefinisikan struktur dan / atau perilaku dari sebuah bangunan atau jenis lain sistem yang akan atau telah dibangun.

Brunelleschi in Italy, in the building of the dome, not only transformed the cathedral and the city of Florence, but also the role and status of the architect. Theory of architecture


Architectural drawings of details of the Palace of Persepolis, Persia (Iran)
The earliest written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century CE. According to Vitruvius, a good building should satisfy the three principles of firmitatis utilitatis venustatis, which translates roughly as –
• Durability - it should stand up robustly and remain in good condition.
• Utility - it should be useful and function well for the people using it.
• Beauty - it should delight people and raise their spirits.
According to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leone Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty primarily as a matter of proportion, although ornament also played a part. For Alberti, the rules of proportion were those that governed the idealised human figure, the Golden Mean. The most important aspect of beauty was therefore an inherent part of an object, rather than something applied superficially; and was based on universal, recognisable truths. The notion of style in the arts was not developed until the 16th century, with the writing of Vasari. The treatises, by the 18th century, had been translated into Italian, French, Spanish and English.



The Parthenon, Athens, Greece, "the supreme example among architectural sites." (Fletcher).
In the early nineteenth century, Augustus Welby Northmore Pugin wrote Contrasts (1836) that, as the titled suggested, contrasted the modern, industrial world, which he disparaged, with an idealized image of neo-medieval world. Gothic architecture, Pugin believed, was the only “true Christian form of architecture.”
The 19th century English art critic, John Ruskin, in his Seven Lamps of Architecture, published 1849, was much narrower in his view of what constituted architecture. Architecture was the "art which so disposes and adorns the edifices raised by men ... that the sight of them" contributes "to his mental health, power, and pleasure". For Ruskin, the aesthetic was of overriding significance. His work goes on to state that a building is not truly a work of architecture unless it is in some way "adorned". For Ruskin, a well-constructed, well-proportioned, functional building needed string courses or rustication, at the very least. On the difference between the ideals of "architecture" and mere "construction", the renowned 20th C. architect Le Corbusier wrote: "You employ stone, wood, and concrete, and with these materials you build houses and palaces: that is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good. I am happy and I say: This is beautiful. That is Architecture".


The National Congress of Brazil, designed by Oscar Niemeyer. Contemporary concepts of architecture
The great 19th century architect of skyscrapers, Louis Sullivan, promoted an overriding precept to architectural design: "Form follows function". While the notion that structural and aesthetic considerations should be entirely subject to functionality was met with both popularity and skepticism, it had the effect of introducing the concept of "function" in place of Vitruvius "utility". "Function" came to be seen as encompassing all criteria of the use, perception and enjoyment of a building, not only practical but also aesthetic, psychological and cultural.


Sydney Opera House, Australia designed by Utzon. Nunzia Rondanini stated, "Through its aesthetic dimension architecture goes beyond the functional aspects that it has in common with other human sciences. Through its own particular way of expressing values, architecture can stimulate and influence social life without presuming that, in and of itself, it will promote social development.'
To restrict the meaning of (architectural) formalism to art for art's sake is not only reactionary; it can also be a purposeless quest for perfection or originality which degrades form into a mere instrumentality".
Among the philosophies that have influenced modern architects and their approach to building design are rationalism, empiricism, structuralism, poststructuralism, and phenomenology. In the late 20th century a new concept was added to those included in the compass of both structure and function, the consideration of sustainability. To satisfy the contemporary ethos a building should be constructed in a manner which is environmentally friendly in terms of the production of its materials, its impact upon the natural and built environment of its surrounding area and the demands that it makes upon non-sustainable power sources for heating, cooling, water and waste management and lighting.
History Main article: History of architecture Vernacular architecture in Denmark. Origins and the ancient world. Architecture first evolved out of the dynamics between needs (shelter, security, worship, etc.) and means (available building materials and attendant skills). As human cultures developed and knowledge began to be formalized through oral traditions and practices, architecture became a craft.
Here there is a process of trial and error, and later improvisation or replication of a successful trial. What is termed Vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day.
Angkor, Cambodia. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of Çatal Höyük in Anatolia and Mohenjo Daro in Pakistan.
In many ancient civilizations, like the Egyptians' and Mesopotamians', architecture and urbanism reflected the constant engagement with the divine and the supernatural, while in other ancient cultures such as Persia architecture and urban planning was used to exemplify the power of the state.
The architecture and urbanism of the Classical civilizations such as the Greek and the Roman evolved from civic ideals rather than religious or empirical ones and new building types emerged. Architectural styles developed. Texts on architecture began to be written in the Classical period. These became canons to be followed in important works, especially religious architecture. Some examples of canons are found in the writings of Vitruvius, the Kao Gong Ji of ancient China and Vaastu Shastra of ancient India and Manjusri vasthu vidya sastra of Sri Lanka. The architecture of different parts of Asia developed along different lines from that of Europe, Buddhist, Hindu and Sikh architecture each having different characteristics. Buddhist architecture, in particular, showed great regional diversity.
In many Asian countries a pantheistic religion led to architectural forms that were designed specifically to enhance the natural landscape. The medieval builder The Taj Mahal, in India
Islamic architecture began in the 7th century CE, developing from a blend of architectural forms from the ancient Middle East and from Byzantium but also developing features to suit the religious and social needs of the society. Examples can be found throughout the Middle East, North Africa and Spain, and were to become a significant stylistic influence on European architecture during the Medieval period.


Wells Cathedral, Somerset, England, United Kingdom. In Europe, in both the Classical and Medieval periods, buildings were not attributed to specific individuals and the names of the architects frequently unknown, despite the vast scale of the many religious buildings extant from this period.
During the Medieval period guilds were formed by craftsmen to organise their trade and written contracts have survived, particularly in relation to ecclesiastical buildings. The role of architect was usually one with that of master mason, or Magister lathomorum as they are sometimes described in contemporary documents. Over time the complexity of buildings and their types increased. General civil construction such as roads and bridges began to be built. Many new building types such as schools, hospitals, and recreational facilities emerged. Renaissance and the architect La Rotonda, Italy by Palladio
With the Renaissance and its emphasis on the individual and humanity rather than religion, and with all its attendant progress and achievements, a new chapter began. Buildings were ascribed to specific architects - Brunelleschi, Alberti, Michelangelo, Palladio - and the cult of the individual had begun.
There was still no dividing line between artist, architect and engineer, or any of the related vocations, and the appellation was often one of regional preference. At this stage, it was still possible for an artist to design a bridge as the level of structural calculations involved was within the scope of the generalist. Early modern and the industrial age With the emerging knowledge in scientific fields and the rise of new materials and technology, architecture and engineering began to separate, and the architect began to concentrate on aesthetics and the humanist aspects, often at the expense of technical aspects of building design. St Pancras Midland Hotel, London, United Kingdom There was also the rise of the "gentleman architect" who usually dealt with wealthy clients and concentrated predominantly on visual qualities derived usually from historical prototypes, typified by the many country houses of Great Britain that were created in the Neo Gothic or Scottish Baronial styles. Formal architectural training in the 19th century, for example at Ecole des Beaux Arts in France, gave much emphasis to the production of beautiful drawings and little to context and feasibility. Effective architects generally received their training in the offices of other architects, graduating to the role from draughtsmen or clerks.
Meanwhile, the Industrial Revolution laid open the door for mass production and consumption. Aesthetics became a criterion for the middle class as ornamented products, once within the province of expensive craftsmanship, became cheaper under machine production. Vernacular architecture became increasingly ornamental. House builders could use current architectural design in their work by combining features found in pattern books and architectural journals. Modernism and reaction of architecture Main article: Modern architecture. The Bauhaus Dessau architecture department from 1925 by Walter Gropius. The dissatisfaction with such a general situation at the turn of the twentieth century gave rise to many new lines of thought that served as precursors to Modern Architecture. Notable among these is the Deutscher Werkbund, formed in 1907 to produce better quality machine made objects. The rise of the profession of industrial design is usually placed here.
Following this lead, the Bauhaus school, founded in Germany in 1919, consciously rejected history and looked at architecture as a synthesis of art, craft, and technology. When Modern architecture was first practiced, it was an avant-garde movement with moral, philosophical, and aesthetic underpinnings. Immediately after World War I, pioneering modernist architects sought to develop a completely new style appropriate for a new post-war social and economic order, focused on meeting the needs of the middle and working classes. They rejected the architectural practice of the academic refinement of historical styles which served the rapidly declining aristocratic order. Fallingwater by Frank Lloyd Wright.
The approach of the Modernist architects was to reduce buildings to pure forms, removing historical references and ornament in favor of functionalist details. Buildings that displayed their construction and structure, exposing steel beams and concrete surfaces instead of hiding them behind traditional forms, were seen as beautiful in their own right. Architects such as Mies van der Rohe worked to create beauty based on the inherent qualities of building materials and modern construction techniques, trading traditional historic forms for simplified geometric forms, celebrating the new means and methods made possible by the Industrial Revolution. Many architects resisted Modernism, finding it devoid of the decorative richness of ornamented styles. As the founders of the International Style lost influence in the late 1970s, Postmodernism developed as a reaction against the austerity of Modernism. Robert Venturi's contention that a "decorated shed" (an ordinary building which is functionally designed inside and embellished on the outside) was better than a "duck" (a building in which the whole form and its function are tied together) gives an idea of this approach. Architecture today Main article: Contemporary architecture Postmodern design at Gare do Oriente, Lisbon, Portugal, by Santiago Calatrava. Part of the architectural profession, and also some non-architects, responded to Modernism and Postmodernism by going to what they considered the root of the problem. They felt that architecture was not a personal philosophical or aesthetic pursuit by individualists; rather it had to consider everyday needs of people and use technology to give a livable environment.
The Design Methodology Movement involving people such as Christopher Alexander started searching for more people-oriented designs. Extensive studies on areas such as behavioral, environmental, and social sciences were done and started informing the design process. As the complexity of buildings began to increase (in terms of structural systems, services, energy and technologies), architecture started becoming more multi-disciplinary. Architecture today usually requires a team of specialist professionals, with the architect being one of many, although usually the team leader.
During the last two decades of the twentieth century and into the new millennium, the field of architecture saw the rise of specializations by project type, technological expertise or project delivery methods. In addition, there has been an increased separation of the 'design' architect from the 'project' architect. Moving the issues of environmental sustainability into the mainstream is a significant development in the architecture profession. Sustainability in architecture was pioneered in the 1970s by architects such as Ian McHarg in the US and Brenda and Robert Vale in the UK and New Zealand. There has been an acceleration in the number of buildings which seek to meet green building sustainable design principles. It is now expected that architects will integrate sustainable principles into their projects. An example of an architecturally innovative green building is the Dynamic Tower which will be powered by wind turbines and solar panels.  See also.

Notes
a. ^ A design architect is one who is responsible for the design
b. ^ A project architect is one who is responsible for ensuring the design is built correctly and who administers building contracts - in non-specialist architectural practices the project architect is also the design architect and the term refers to the differing roles the architect plays at differing stages of the process.
Kant's architectonic system
Kant created an architectonic system in which there is a progression of phases from the most formal to the most empirical.[1] "Kant develops his system of corporeal nature in the following way. He starts in the Critique with the most formal act of human cognition, called by him the transcendental unity of apperception, and its various aspects, called the logical functions of judgment. He then proceeds to the pure categories of the understanding, and then to the schematized categories, and finally to the transcendental principles of nature in general." It is within this system that the transcendental schemata serve a crucial purpose. Purpose of the Schematism chapter Kant wrote the chapter on Schematism in his Critique of Pure Reason to solve the problem of "...how we can ensure that categories have 'sense and significance.' " A posteriori concepts have sense when they are derived from a mental image that is based on experienced sense impressions. Kant's a priori concepts are alleged to have sense when they are derived from a non–experienced mental schema, trace, outline, sketch, or minimal image.
Whenever two things are totally different from each other, yet must interact, there must be some common characteristic that they share in order to somehow relate to one another. Categories, or a priori concepts, have, according to Kant, a basic and necessary importance for human knowledge, even though they are totally different from sensations. However, they must be connected in some way with sensed experience because "… an a priori concept which cannot, as it were, establish any empirical connections is a fraud … the purpose of the Schematism chapter was to show that the categories at least do have satisfactory empirical connections. "Obscurity of the concept "Schema" Kant introduced the concept of the transcendental schema in his chapter entitled "Of the Schematism of the Pure Concepts of the Understanding." It is considered to be one of Kant's more difficult chapters. Even though he knew that he was not writing for a popular readership, Kant twice tried to apologize for this chapter by calling it "very dry" and "dry and tedious." Professor W.H. Walsh, of the University of Edinburgh, wrote: "The chapter on Schematism probably presents more difficulties to the uncommitted but sympathetic reader than any other part of the Critique of Pure Reason. Not only are the details of the argument highly obscure (that, after all, is a common enough experience in reading Kant, though one is not often so baffled as one is here): it is hard to say in plain terms what general point or points Kant is seeking to establish." Schopenhauer referred to it as "…the strange 'Chapter on the Schematism of the Pure Concepts of the Understanding,' which is well known for its great obscurity, since no one has ever been able to make anything out of it." In Schopenhauer's criticism of Kant's schemata, he attempted to clear up the obscurity by attributing Kant's concept of schemata simply to a psychological need for architectonic symmetry in his writings. Empirical concepts are based on empirical perceptions. Kant, however, tried to claim that, analogously, pure concepts (Categories) also have a basis. But this contradicts his previous assertion that pure concepts simply exist in the human mind and are not based on pure, schematic perceptions. Schopenhauer also alleged that schemata were introduced merely to give plausibility to Kant's description of the categories or pure concepts of the understanding. The article on Kant in the Encyclopedia of Philosophy calls Kant's schematism a "baffling doctrine " with "cryptic sentences." Josiah Royce referred to "the perplexing doctrine of the Schema." The Scottish philosopher Robert Adamson wrote: "Kant's manner of explaining the functions of schematism is extremely apt to be misunderstood, and to mislead." After more than two centuries, Kant's explanation of schema still seems to be unclear to many readers. In their book on Parallel distributed processing, the PDP Research Group discussed Kant's schemata when they appropriated that word to designate their concept of image schemata. "The schema," they wrote, "throughout history, has been a concept shrouded in mystery. Kant's … use of the term has been provocative but difficult to understand." After this sentence, no further attempt was made to discuss Kant's term and the concept that it designates. Explication of the Kantian account of schemata Three types of concepts and their schemata
Empirical concepts An empirical concept is the abstract thought of what is common to several perceptions. When an empirical concept is said to contain an object, whatever is thought in the concept must be intuited in the mental representation of the object. Examples of intuitive perceptions that are the content of empirical concepts are vague images that are imagined in order to connect a concept with the perceptions from which it was derived as their common feature. "Intuitions," Kant wrote, "are always required to verify or demonstrate the reality of our concepts." These examples ensure that "our abstract thinking has not strayed far from the safe ground of perception, and has possibly become somewhat high–flown or even a mere idle display of words.". This is because "concepts are quite impossible, and are utterly without meaning or signification, unless an object is given for the concepts themselves, or at least for the elements of which they consist." For example, "The concept of a dog signifies a rule according to which my imagination can trace, delineate, or draw a general outline, figure, or shape of a four-footed animal without being restricted to any single and particular shape supplied by experience."In order to prevent the emptiness of "thoughts without contents", it is "necessary to make our concepts sensible, i.e., to add an object of intuition to them." In order to test whether a concept is sensible, we sometimes " … go back to perception only tentatively and for the moment, by calling up in imagination a perception corresponding to the concept that occupies us at the moment, a perception that can never be quite adequate to the (general) concept, but is a mere representative of it for the time being. … Kant calls a fleeting phantasm of this kind a schema." Pure sensuous concepts
A pure, sensuous concept is the construction or mental drawing of what is common to several geometrical figures. These mathematical concepts are not based on objective visual images. They are based on schemata that exist only in thought. Any particular image could not be as general as the concept. The schemata are rules that allow the imagination to mentally construct or draw or trace a pure, general geometrical form that gives the pure, sensuous concept significance. "… [T]o possess the schema corresponding to the concept triangle is to be able to envisage the variety of things to which the word "triangle" applies." "[T]he schema of sensuous concepts (such as of figures in space) is a product and, as it were, a monogram of the pure imagination a priori. Images become possible only through the schema. But the images must always be connected with the concept only by means of the designated schema. Otherwise, the images can never be fully congruent to the general concept."
Pure concepts of the understanding. A pure concept of the understanding, or category, is a characteristic, predicate, attribute, quality, or property of any possible object in general. These concepts are not abstractions of what is common to several perceived, particular, individual objects, as are empirical concepts. "Since the categories are a priori and are therefore not abstractions from sense perceptions, they owe their origin to the very nature of the mind itself." They are not derived from perceptions of external objects, as are empirical concepts. Instead, they are the result of the way that the mind is constituted or formed. They come from within, not without. Kant claimed that the schemata of pure, non-empirical concepts, or categories, provide a reference to intuition in a way similar to the manner of empirical concepts. "If the concepts are empirical, the intuitions are called examples: if they are pure concepts of the understanding, the intuitions are called schemata." In the same way that examples provide signification for empirical concepts, schemata help to answer the question of "whether operating with the categories is anything other than playing with words."
Since the pure concepts of the understanding, or categories, are characteristics of all objects in general, they can never be associated with the image of any specific, particular, individual object. "Since they are pure, they cannot be pictures..." "Yet there must be some connection between the abstract idea and the experienced world to which the idea is expected to apply... "In order for the pure categories to have objective validity (and not merely subjective validity) they must be related to sensibility."  Applying pure concepts to sense impressions The categories, or pure concepts of the understanding, are a priori logical innate forms that are conditions of the possibility of things in general, or of things as such. A thing can become a known object of thought when an a posteriori sense impression is comprehended through the forms of the categories. Categories and sense impressions are totally different from each other. Categories are utterly heterogeneous with the perceptions that are experienced through the sense organs. In order for specific phenomena of Nature to be thought from the combination of categories (pure concepts) and sense perceptions, there must be a third, mediating procedure that connects them. This mediator is a transcendental schema. Transcendental schemata meaningfully join the empty "thoughts without content" and the blind "intuitions without concepts." Transcendental Schemata
Transcendental schema are not related to empirical concepts or to mathematical concepts. These schemata connect pure concepts of the understanding, or categories, to the phenomenal appearance of objects in general, objects as such, or all objects. Judgment Transcendental Schematism results from the ability to make judgments. " … the judgment … schematizes these concepts a priori and applies these schemata, without which no experiential judgment would be possible, to each empirical synthesis. … the transcendental schematism of judgment provides it [judgment] with a rule under which given empirical intuitions are to be subsumed." Kant defined the Greek word hypotyposis as a " … rendering perceptible to the senses, making sensual (Versinnlichung)." The usual definition is "example, pattern, outline, or sketch." If a hypotyposis is schematic, according to Kant, "...to a concept, which is comprehended by the understanding, the corresponding intuition is given a priori..." This is in opposition to a symbolic hypotyposis, like God, in which the concept can only be thought by Reason and to which no sensible intuition can be adequate. Schemata contain direct presentations of the concept. They make this presentation demonstratively, not by the use of analogies. Judgment, according to Kant, works mechanically with given appearances and brings them under concepts. It does this as a tool that is utilized and controlled by both the understanding and the senses.
Time Categories, or pure concepts of the understanding, are forms of objects in general. However, they can become forms of specific internal and external objects of thought if they are related to time.
Everything is experienced in time. This applies to our internal selves as well as to all external objects. Since categories are the forms through which every specific thing can be thought as being in time, categories are related to time. Thus, pure concepts, or categories, and phenomenal objects share time as a common feature. Therefore, time is the means by which an intuited phenomenon is subsumed under a pure concept. Schemata are transcendental time determinations. "Hence it will be possible for the category to be applied to appearances by means of the transcendental time determination, which, as the schema of the concepts of the understanding, mediates the subsumption of appearances under the category." Schemata are procedural rules, not images Because schemata are determinations of objects in general, not specific, individual objects, they are not particular images. Kant asserted that "… a schema must be distinguished from an image." A schema is a procedural rule. The rule prescribes the way to relate a pure concept to an object in general. Schemata are ways of applying pure concepts (categories) to sense impressions. They are prescriptions for graphically illustrating a pure concept. A schema is a method for representing a non-empirical concept in any image as such or any image in general. "… This representation of a general procedure of the imagination for providing a concept with its image, I call the schema of such a concept. " … For Kant a schema is not an image, but a capacity to form images or (perhaps) to construct models. "The schema of a pure concept of the understanding is something which can never be made into an image..." Illustrations of Different categories and their schemata. Each category has one schema. Some schemas are shared by other categories in their class.
• The categories of quantity all share the schema of number. Quantity is related to a numerical time series. William H.S. Monck claimed that Kant can be understood as saying "In apprehending an object I always successively add part to part, and thus generate a series of determinate magnitude." Unity is one moment in time. Plurality is several moments. Totality is expressed as all moments. But Monck noted that "Kant does not trace out specially the Schemata of the Categories of Unity, Plurality, and Totality." Monck supposed: "In the Category of Unity I presume we should stop at the first term of the Time–series: for the Category of Plurality we should represent the addition of unit to unit without laying down any determinate limit; and for the Category of Totality we should limit the number of units and complete the addition up to this number."
• The categories of quality all have degrees of reality as their schema. Quality is related to the content of real being in time. Kant metaphorically explained the schema of quality as the filling up of time with a sensation. Monck paraphrased Kant as saying, "We may speak of time as being more completely filled when the sensation is more vivid, and less completely filled when the sensation is weaker. If the sensation is sufficiently vivid the present moment is so filled with it that it seems impossible to attend to, or even be conscious of any other sensation simultaneously; but when it becomes weaker we have leisure to perceive other sensations also. This occurs by degrees. "We can represent this filling as taking place by a gradual increase from zero (empty time) to any given degree of vividness, or by a similar descent from the sensation of the moment to zero." Reality is the experience of sensation in time. Negation is the absence of sensation in time. Limitation is the range of degrees, between the transition from full to empty, by which things are sensed in time. But Monck stated that "Again Kant does not here give in detail the Schemata of the Categories of Reality, Negation, and Limitation." He qualifiedly suggested that "In the first case [Reality], we should, perhaps, represent the sensation as occupying the present moment to the exclusion of everything else; in the second [Negation] the sensation as entirely absent from the present moment; in the third [Limitation] the sensation as occupying the present moment along with others.
• "The Schema of the Category of Relation is the Order of Time." In the class of relation, each category has its own schema. Substance's schema is the permanence of the unchanging substance (subject) to which accidents (predicates) belong, or the permanence of the object in time. Causality's schema is the necessary succession of a consequent to an antecedent. That is, "… the Schema of the Category of Cause is its regular Antecedence in Time (i.e. Succession in Time determined by fixed law)." The category of community has the schema of the necessary coexistence of the accidents of one substance with the accidents of another substance. This communal interaction consists of the changing accidents of one substance having their cause in the changing accidents of another substance, and vice versa. This can be understood as "… the Simultaneity of objects in Time."
• "The Schema of the Category of Modality according to Kant is Time itself as related to the Existence of the object." In the class of modality, the category of possibility has the schema of possibility at any time. The schema of actual existence at a certain time belongs to the category of existence. Finally, the category of necessity has the schema of being an object at all times.
Even though Kant provided these illustrations and examples of schemata, author John Mahaffy claimed that the topic remained obscure. He wrote, "I may add, that these illustrations of the various schemata are developed and explained by the succeeding chapters on the Principles which embody them, and that it is impossible to make them clear to the reader until he has studied the theory of the Principles." Schematized and unschematized categories. The schemata give the categories a "cash value", as though the category is like paper money and sense experience is analogous to precious metal. A schema is the agreement or harmony of a category with sensual phenomena. For example, "Number is the quantity of the phenomenon; sensation is the reality of the phenomenon; the permanence and endurance of things is the substance of the phenomenon, eternity is the necessity of the phenomenon, etc." In this way, the schemata restrict the categories to conditions of sensibility. "Schematism and the schemas thus have the property of 'realizing' the categories at the same time as restricting their scope to appearances." Categories cannot be realized in objects that are not detectable by the senses, that is, are not phenomenal objects or objects that appear to an observer. "The schemata of the pure concepts of the understanding are, therefore, the true and sole conditions for providing these concepts with a reference to objects and hence with signification. And therefore the categories have, in the end, no other use than a possible empirical one." In order for categories to refer to perceived, experienced objects, they must be schematized. If a category is not schematized, then it has no reference to perception. An unschematized category can be thought, but can not be known. If something can never be perceived, it can never be known. Schemata represent things in general as they appear, not as they might otherwise exist. "Categories, therefore, without schemata are only functions of the understanding necessary for concepts, but do not themselves represent any object." With the transcendental determination of time as the transcendental schema, " … use of the categories is clearly restricted to the range of things that fall within time — meaning, for Kant, restricted to phenomena." Metaphysical entities that are not related to time, such as spontaneous or uncaused movements, immortal souls, and eternal gods, are products of unschematized categories. They can be thought, but not known.
Discrepancies
According to Professor W. H. Walsh, there is an apparent discrepancy in Kant's central arguments about schematism. Kant, according to Professor Walsh, first claimed that empirical concepts do not require schemata. Only pure concepts need schemata in order to be realized. This is because pure concepts are totally different from intuitions, whereas, empirical concepts are abstracted from intuitions and are therefore homogeneous with them. But in another part of his chapter, Kant states that mathematical concepts have schemata. "In fact," he wrote, "it is schemata, not images of objects, that lie at the basis of our pure sensible (i.e., geometrical) concepts." In discussing schematism as the method of representing in one image a certain mathematical quantity according to a certain concept, he wrote: "This representation of a general procedure of the imagination by which a concept receives its image, I call the schema of such concept." With regard to pure concepts, Kant then declares, "The schema of a pure concept of the understanding, on the contrary, is something which can never be made into an image … ."  Kant, according to Professor Walsh, has two distinct ways of describing schemata. "Sometimes, as at the beginning of his discussion, he speaks as if a schema were a feature of things which could be pointed to … .In another place, Kant " … speaks as if schematism were a procedure … ."  Alternative schemata Kant said that the schema of a concept is the representation of a general procedure of the imagination by which an image can be supplied for a concept. Kant claimed that time is the only proper and appropriate transcendental schema because it shares the a priori category's generality and purity as well as any a posteriori phenomenon's manner of appearance. However, it may be true that time is not the only possible schema. Space "Even more remarkable, however, is the fact that in order to understand the possibility of things as consequent upon the categories, and hence in order to establish the categories' objective reality, we need not merely intuitions but indeed always outer intuitions." Since space is the form of all appearances of the outer senses, it may seem that space could serve as a schema. Indeed, any phenomenon that requires space, as well as time, as a form would also need a spatial schema. "This suggests that he may have thought at one point of recasting the Schematism argument in a fundamental way, by substituting space for time; but if he had this idea, he did not carry it out." In the editor's introduction to his translation of the Critique, Paul Guyer asserted that "…although the content of the transcendental schemata for the categories may be explicated in purely temporal terms, the use of these schemata in turn depends upon judgments about the spatial properties and relations of at least some objects of empirical judgment." Guyer claimed that this declaration was clarified in Kant's "The System of All Principles" section. In this way, the use of schemata is supposed to involve both space and time, instead of merely time.
Organism
In order to show how time may not be the only schema, Professor Walsh suggested that there is "… the possibility of making sense of the categories in organic as opposed to mechanical terms." He hypothesized that "Elements in an organic complex would here take the place of elements in a temporal situation. Substance might be interpreted in terms of growth and form as opposed to what underlies mechanical change, and causality be thought of in terms of purpose and function." However, Professor Walsh concluded that Kant's choice of time as schema was more precise than any alternative choices. In spite of the general difficulty in understanding Schematism, he asserted that "… Kant's doctrine of schematism, if not altogether satisfactory at the theoretical level, will continue to stand on the strong empirical ground that the schemata offered do enable us to give real meaning to the categories and find for them a genuine use." Schemata of systematic unity In his discussion of the Architectonic of Pure Reason, Kant utilized the concept of schema in a way that was similar to his discussion of the schemata of the Categories. A science's whole systematic organization consists of parts. The parts are various cognitions or units of knowledge. The parts are united under one idea which determines the relation of the parts to each other and also the purpose of the whole system. A schema is needed to execute, carry out, or realize this unifying idea and put it into effect. This schema is a sketch or outline of the way that the parts of knowledge are organized into a whole system of science. A schema which is sketched, designed, or drafted in accordance with accidental, empirical purposes results in mere technical unity. But a schema that is drawn up from an a priori rational idea is the foundational outline of architectonic unity. Science must have architectonic unity. "For the schema of what we call science must contain the whole's outline (monogramma) and the whole's division into parts in conformity with the idea — i.e., it must contain these a priori — and must distinguish this whole from all others with certainty and according to principles." This use of the concept of schema is similar to Kant's previous use. It is a minimal outline, monogram, or diagram that realizes or executes an abstract, general concept or idea (Idee) as actual, perceptual experience. Adamson's interpretation Scottish philosopher Robert Adamson wrote from a Hegelian standpoint. He believed that Kant's analysis of knowledge into the separate topics of intuition, schema, and concept was mechanical and artificial. Adamson claimed that "Thought and Intuition are organically united in the schema.""We are not to suppose that the subsumption [of the intuition under the pure notion] is mechanical; that the particular is something distinct from the universal. The union is organic; the particular is only the universal under a special form. The same function of synthesis, which in pure abstraction we call category, is, in realization, the schema, and the intuition is not apart from the schema."Kant's abstract analysis of perceptual knowledge was, according to Adamson, the misleading separation of an organic unity into individual components. He asserted that "… we must on no account regard Notion, Schema, and Intuition, as three parts of perception which would exist in isolation." Elaborations of Kant's notion of schema in cognitive science
The philosopher Mark Johnson discusses Kant's conception of a schema with respect to developing a theory of the imagination within cognitive science. Johnson's theory makes use of Kant's insights that analogy is the cognitive mechanism which links sensible percepts to their conceptual categories, and that creative analogy—or what Johnson calls conceptual metaphor—is the cognitive mechanism by which we come to have our understanding of those abstract concepts and categories of which we have less direct sensible experience. He proposes that we use imaginative schemata to structure abstract concepts largely in terms a set of spatial analogies he calls image schemata. In Johnson's view, we acquire image schemata primarily from recurrent patterns of experiences in infancy and early childhood, and then reuse these image schemata in a metaphoric fashion both to reason abstractly and as we speak our language.
Part of a series on Immanuel Kant
• Architects in practice Architecture is a business in which technical knowledge, management, and an understanding of business are as important as design. An architect accepts a commission from a client. The commission might involve preparing feasibility reports, building audits, the design of a building or of several buildings, structures, and the spaces among them. The architect participates in developing the requirements the client wants in the building. Throughout the project (planning to occupancy), the architect co-ordinates a design team. Structural, mechanical, and electrical engineers and other specialists, are hired by the client or the architect, who must ensure that the work is co-ordinated to construct the design. An architect must understand building and operational codes, the construction methods available to the builder in constructing a client's building and structures, and the desired results with the actual costs and construction schedule limits. Work time is usually a standard work week, but when working towards a deadline the architect often works long hours. Architects are office-based professionals, but the work usually includes visiting clients and regular visits to job sites.
Design role. Architects deal with local and federal jurisdictions about regulations and building codes. The architect might need to comply with local planning and zoning laws, such as required setbacks, height limitations, parking requirements, transparency requirements (windows), and land use. Some established jurisdictions require adherence to design and historic preservation guidelines.
Architects prepare the technical documents (construction drawings and specifications), usually coordinated with and supplemented by various engineers, that are filed for obtaining permits (development and building permits) that require compliance with building, seismic, and relevant federal and local regulations. These construction drawings and specifications are also used for pricing the work, and for construction. Construction role Architects typically put projects to tender on behalf of their clients, advise on the award of the project to a general contractor, and review the progress of the work during construction. They typically review subcontractor shop drawings and other submittals, prepare and issue site instructions, and provide construction contract administration and Certificates for Payment to the contractor (see also Design-bid-build). In many jurisdictions, mandatory certification or assurance of the work is required. Depending on the client's needs and the jurisdiction's requirements, the spectrum of the architect's services may be extensive (detailed document preparation and construction review) or less inclusive (such as allowing a contractor to exercise considerable design-build functions). With very large, complex projects, an independent construction manager is sometimes hired to assist in design and to manage construction. In the United Kingdom and other countries, a quantity surveyor is often part of the team to provide cost consulting. Alternate practice and specializations
Recent decades have seen the rise of specializations within the profession. Many architects and architectural firms focus on certain project types (for example, health care, retail, public housing), technological expertise or project delivery methods. Some architects specialize as building code, building envelope, sustainable design, historic preservation, accessibility and other forms of specialist consultants. Many architects elect to move into real estate (property) development, corporate facilities planning, project management, construction management, interior design or other related roles.
Professional requirements in the English-speaking world Australia In Australia, the title of architect is legally protected but architects are registered through state boards. These boards are affiliated through the Architects Accreditation Council of Australia (AACA)[2]. The Architect Registration also provides accreditation for schools and assessments for architects with overseas qualifications for the purposes of migration. There are three key requirements for registration: a professional degree from a school of architecture accredited by the AACA; at least two years of practical experience, and; the completion of the architectural practice examination. Architects may also belong to the Australian Institute of Architects (formerly the Royal Australian Institute of Architects) which is the professional organization and members use the suffix AIA after their name. Most States have legislation which covers the use of the title "architect" and makes it an offence for abusers of the title. As this can vary, it is essential to check the relevant legislation applicable in each State.
Canada
In Canada, architects are required to meet three common requirements for registration: education, experience, and examination. Educational requirements generally consist of an M.Arch. degree and are certified by the Canadian Architectural Certification Board (CACB). For degreed candidates, the experience requirement is typically the Intern Architect Program (IAP). The provincial associations of architects, by the authority granted under their respective provincial Architects Act, require that Interns gain a minimum of 5,600 hours of work experience. The fundamental purpose of the pre-registration/licensing employment period is to ensure that the Intern is provided with sufficient experience to meet the standards of practical skill and level of competence required to engage in the practice of architecture. This experience is diversified into four main categories and 16 sub-categories, and must be completed working under the direct supervision of a registered architect. At present, all jurisdictions use the Architect Registration Examination (ARE), a series of nine computerized exams administered by the National Council of Architectural Registration Boards (NCARB). As well, all jurisdictions except British Columbia recognize the Examination for Architects in Canada (ExAC), administered by the Pan Canadian ExAC Committee. Upon completion of the educational requirements, IAP, and examinations, one can apply for registration/license. The average age of an intern is 39 years old. An annual fee must be paid, and continuing education requirements met, in order to maintain a license to practice. The .Royal Architectural Institute of Canada (RAIC) was established in 1907 and is a voluntary national association representing more than 3,600 architects and Faculty and graduates of accredited Canadian Schools of Architecture.[3] The RAIC aims to be "the voice of Architecture and its practice in Canada". Members are permitted to use the suffix MRAIC after their names. The suffix FRAIC (Fellow of the RAIC) is used by members of the RAIC College of Fellows. Not all members of the RAIC hold accredited degrees in architecture, and not all Canadian architects are members of the RAIC.
Ireland
The main body for Architecture in Ireland is the Royal Institute of Architects in Ireland, RIAI. Members may use the affix MRIAI and are registered to use the title "Architect" in company stationery. The title has only recently been protected. To become a registered Architect, it usually takes five years' full-time study in the recognised schools of Architecture, followed by a minimum of two years approved experience, further specific training in professional competence and a written examination to gain admission to the RIAI. In all, it takes a minimum of seven years to gain registration. More details can be found on the RIAI website.
Singapore
In Singapore, university study is required (such as the five-year course of study at the National University of Singapore or certain approved foreign universities). Upon completion of university, additional training by working for a minimum of two years under a registered architect is required in order to become registered. Singaporean law governs the use of the term "architect" and prescribes the requirements to be listed in the Register of Architects. Membership in the Singapore Institute of Architects is a voluntary professional credential.
United Kingdom
In the United Kingdom, practicing under the name, style or title "architect" is restricted by law to those registered at the Architects Registration Board. It usually takes a minimum of seven years to obtain the necessary qualifications and experience for registration. Those wishing to become registered must first study at a recognized university-level school of architecture. Though there are some variations from university to university, the basic principle is that in order to qualify as an architect a candidate must pass through three stages which are administered by the Royal Institute of British Architects:
• On completing an initial degree in architecture (usually three or four years, usually either a BA, BSc, or BArch) the candidate receives exemption from RIBA Part I. There then follows a period of a minimum of one year which the candidate spends in an architect's office gaining work experience.
• The candidate must then complete a post-graduate university course, usually two years, to receive either a graduate diploma (Dip Arch), Masters (MArch) or B(Arch). On completing that course, the candidate receives exemption from Part II of the RIBA process.
- The candidate must then spend a further period of at least one year gaining experience before being allowed to take the RIBA Part III examination in Professional Practice and Management.

United States
In the United States, people wishing to become licensed architects are required to meet the requirements of their respective state. Each state has a registration board to oversee that state's licensure laws. In 1919, the National Council of Architectural Registration Boards (NCARB) was created to ensure parity between the states' often conflicting rules. The registration boards of each of the 50 states (and 5 territories), are NCARB member boards. Requirements vary between jurisdictions, and there are three common requirements for registration: education, experience and examination. About half of the States require a professional degree from a school accredited by the National Architectural Accrediting Board (NAAB) to satisfy their education requirement; this would be either a B.Arch or M.Arch degree. The experience requirement for degreed candidates is typically the Intern Development Program (IDP), a joint program of NCARB and the American Institute of Architects (AIA). IDP creates a framework to identify for the intern architect base skills and core-competencies. The intern architect needs to earn 700 training units (TUs) diversified into 16 categories; each TU is equivalent to 8 hours of experience working under the direct supervision of a licensed Architect. The states that waive the degree requirement typically require a full 10 years experience in combination with the I.D.P diversification requirements before the candidate is eligible to sit for the examination. California requires C-IDP (Comprehensive Intern Development Program) which builds upon the seat time requirement of IDP with the need to document learning having occurred. All jurisdictions use the Architect Registration Examination (ARE), a series of seven (formerly nine) computerized exams administered by NCARB. The NCARB also has a certification for those architects meeting NCARB's model standard: NAAB degree, IDP and ARE passage. This certificate facilitates reciprocity between the member boards should an architect desire registration in a different jurisdiction. All architects licensed by their respective states have professional status as Registered Architects (RA).
Depending on the policies of the registration board for the state in question, it is sometimes possible to become licensed as an Architect in other ways: reciprocal licensure for over-seas architects and working under an architect as an intern for an extended period of time. For degrees in the United States, Australia, Canada and the UK, see Bachelor of Architecture and Master of Architecture.
For schools in the US, see US Architecture Schools. Professionals engaged in the design and supervision of construction projects prior to the 20th century were not necessarily trained in a separate architecture program in an academic setting. Instead, they usually carried the title of Master Builder, or surveyor, after serving a number of years as an apprentice (such as Sir Christopher Wren). The formal study of architecture in academic institutions played a pivotal role in the development of the profession as a whole, serving as a focal point for advances in architectural technology and theory.
Earnings
Earnings for architects range widely, depending on where and how they work. Salaries also vary depending on the size and location of the practice. Earnings have traditionally been dependent on the local economic conditions but, with rapid globalization, this is becoming less of a factor for larger international firms. Some architects become real estate (property) developers or develop specialized roles where they can earn a significantly higher income than the industry median.
Canada
According to a 2007 survey by the Ontario Association of Architects, Senior architects typically have earnings that exceed $100,000 annually, especially in the larger urban centres, and principals in larger firms can earn substantially more. Intern Architects salaries ranged from $38,482 to $52,732.
United States
According to the 2008–09 Occupation Outlook Handbook published by the US Department of Labor, the median salary of architects was $76,750. Intern architects typically earn between $24,000 and $34,000 depending on experience prior to licensure. Architects that have completed the internship period can expect an average starting salary of between $51,709 and $64,519. For 10 years' experience, the base compensation level increases significantly to an average range of $62,608–79,919; that range reaches $72,678–96,928 for architects with 15 years' experience. Senior architects and partners typically have earnings that exceed $100,000 annually. It is not unusual for an officer or equity partner to earn a base salary of $235,000, with a bonus of $200,000. Due to the major stake in ownership that equity partners may have, they can earn incomes approaching, and occasionally surpassing, seven figures.
UK
The average salary (2008–09) in the United Kingdom is £45,000, with a typical range for principals between £51,000 and £90,000. [6] The Royal Institute of British Architects (RIBA) provides a guide to the salaries typical of the various stages of qualification[7]: Beginning level candidates (part one) can expect between £12,000 and £20,000. Recent graduates (part two) earn between £15,000 and £27,000. Newly registered architects (part three) earn £29,000–£34,000; part three, three to five years post-registration £34,000–42,000 (salary data collected March 2008). The range of typical salaries at senior levels (after 10–15 years in role) is £36,000–80,000, depending on the seniority of the position.
Finland
The average salary for a Finnish architect starting out in a private office is roughly €33,000 net. Architects working for the municipalities are paid according to the Finnish government's salary system, in which the salary is determined by the level of stringency and expertise needed and how well a person copes with the requirements. The average base salary is about €35,000 net.  Professional organizations. Refer to the international list of professional architecture organizations for groups created to promote career and business development in architecture. A wide variety of prizes are awarded to architects to acknowledge superior buildings, structures and professional careers. Prizes and awards. The most prestigious award a living architect can receive is the Pritzker Prize, often termed the "Nobel Prize for architecture." Other awards for excellence in architecture are given by national professional associations such as the American Institute of Architects (AIA) and Royal Institute of British Architects (RIBA). Architects who have made outstanding contributions to the profession through design excellence, contributions in the field of architectural education, or to the advancement of the profession are elected to the College of Fellows of the American Institute of Architects and are given the postnomial FAIA after their name. Other prestigious architectural awards are the Alvar Aalto Medal (Finland) and the Carlsberg Architecture Prize (Denmark).
