After the German philosopher and educator Alexander Gottlieb Baumgarten had introduced the neologism aesthetics about 1750, the visual merits of all artifacts tended to be assessed more subjectively than objectively, and, in the criticism of all those sensory stimuli that, for want of a better term, critics somewhat indiscriminately lumped together as the fine arts, the visual criteria were extended to include not only beauty but also sublimity, picturesqueness, and even ugliness. Now it is clear that, once ugliness is equated with beauty, both terms (being contradictory) become virtually meaningless. But ugliness, after the mid-19th century, was not only one of the most important themes of many popular dramas and novels. Ugliness was also often considered the most appropriate architectural expression for all sorts of virtues—especially those of manliness, sincerity, and so on.
Before 1750, architects had expressed these qualities more subtly (e.g., by slight modifications of proportions or by unobtrusive ornament). In later years, when the value of proportion and ornament became highly controversial, architectural theorists tended to avoid committing themselves to any criteria that might be subsumed under the heading venustas. In the last resort, however, some concept of beauty must be essential to any theory of architecture, and, whether one considers Le Corbusier’s buildings beautiful or not, his most stabilizing contribution toward the theory of modern architecture was undoubtedly his constant reiteration of this term and his insistence on the traditional view that beauty in architecture is essentially based on harmonious proportions, mathematically conceived.
In the 20th century the main obstacle to an acceptance of Alberti’s notions of pulchritudo and ornamentum resulted from the influence of nonrepresentational sculpture after 1918, whereby ornament was no longer conceived as an enrichment of proportioned structure but as an integral, all-pervading part of each building’s totality. This ideal of the fusion between good proportions and “auxiliary brightness” was expressed by Walter Gropius in The New Architecture and the Bauhaus when he wrote in 1935:
Our ultimate goal, therefore, was the composite but inseparable work of art, the great building, in which the old dividing-line between monumental and decorative elements would have disappeared for ever.
The idea was accepted in most schools of architecture by the mid-20th century, but one may question whether it fully justified the expectations of its protagonists, once it had been exemplified and proliferated in so many urban environments. It is by no means certain that Gropius’s concept of the fundamental interdependence of architectural proportion and architectural ornament was irrevocably established by the Bauhaus theorists or that future architectural theorists need only concentrate on such minor modifications to the concept as may be required by sociological and technological developments. Utilitas
The notion that a building is defective unless the spaces provided are adequate and appropriate for their intended usage would seem obvious. Yet the statement itself has been a source of controversy since the 1960s. The main reasons for the controversy are: first, whereas there are seldom exact statistical means of computing spatial adequacy or appropriateness, there are many building types or building elements for which one cannot even establish the optimum forms and dimensions with any confidence that they will be generally accepted. Second, edifices are frequently used for purposes other than those for which they were originally planned. Furthermore, there is some doubt as to whether “form follows function” or “function follows form,” since, although, in general, it can reasonably be assumed that an architect’s task is to construct specific spaces for the fulfillment of predetermined functions, there is plenty of historical evidence to suggest that many important social institutions have resulted from spaces already built. No better example could be found than the evolution of parliamentary systems. The British system, based on the concept of legislatures in which the sovereign’s government and the sovereign’s opposition confront each other, originated in the fact that the earliest parliaments met in the medieval palace chapel. The French system, created concurrently with the Greek and Roman revivals, was based on the concept of legislatures addressed by orators, and its environment was that of an antique theatre. In the former system the seating was designed in accordance with the liturgical requirements of a Christian church; in the latter, with the evolution of Greek drama. Neither had anything to do with preconceived notions regarding the most effective environment for parliamentary debate, yet both have had divergent influences on constitutional procedures, thereby deeply affecting the whole theory of government.
Third, the exact significance of what is meant by “adequate appropriate spaces” becomes far more complex in buildings requiring a large number of interrelated spaces than it is in single-cell buildings. The emotional effect of transitions from spacious to constricted volumes and vice versa transcends in architectural importance the statistical evaluation of floor areas; a fact which explains the attractiveness of theories that have tacitly adopted places of worship as spatial paradigms and bolstered their arguments by historical reference to temples and churches. This bias is perceptible not only in the most influential theories enunciated before 1900 (when the prototypes were either primeval, antique, or medieval) but also in the most influential ideas promulgated by such great architectural leaders of the 20th century as Frank Lloyd Wright and Ludwig Mies van der Rohe.
The idealization of monumental single-cell spaces is sometimes justified, but the difficulty of evolving theories of planning by the use of historical prototypes should be emphasized. It is in this branch of architectural theory that the influences of historicism have been most insidious, precisely because they are less obvious here than in systems of construction, of proportions, and of ornamentation. Such influences persist mainly because of art-historical indifference to the essential distinction between building types, since such distinction conflicts with the chronological sequence of particular architects’ stylistic evolution, but it is for this reason that Julien Guadet’s greatest contribution to the theory of architecture may well have been his decision to evolve a history of architecture in which all buildings were classified solely in accordance with their function.
