Design requires its own specialized knowledge; it makes new and considerably greater demands on the social sciences and humanities. It encourages science to develop. The problem of the interaction between science and art is a philosophical one. For that reason we want to explain how science affects the architect. Although an architect knows that science and art are both the results of the creative process, it is necessary to emphasize what the scope of the problems connected with this interaction depends on, and the social and cultural environment in which it exists. This is despite that scientific and technological progress sometimes leads to a deterioration of the aesthetic state of the architect’s way of design.
