The special character of the discipline of Architecture places it in a central position in the traditional art v. science debate. As the institutions of Art and Science have both metamorphosed, the nature of the debate and its impact on the discipline of Architecture have evolved dramatically. A poet or a sculptor, on the one hand, or a biologist or a physicist, on the other, can choose to ignore the continuing long-term debate with relative impunity, isolated at what we generally imagine to be the extremes of two different universes. The architect, however, cannot afford the luxury of this attitude because of the simultaneous immediacy of both technical and esthetic requirements. The architect lives daily at the boundary and continually is faced with the real or imagined ambiguity that this implies. I propose to review some of the central issues in this process of metamorphosis, i.e., rationality, objectivity, creativity, intuition, etc. and I will argue that changes in the philosophical positions upon which the debate is carried on in the larger culture should cause us to reconsider the terms used and the positions taken in the debate as it is carried on in the micro-culture of architecture. It will be my aim to support the following conclusions 1. That the philosophical basis on which traditional Science relied to reject Humanism because of its reliance on intuition and the irrational, and which supported Science's reliance on inductvism as a method, on objectivism as an ontology, and on positivism as an ideology collapsed 70 years ago and, 2. That the philosophical basis on which traditional Humanism relied to reject the claims of Science to operate in the realm of human affairs, and which supported Humanism's reliance on interpretation as a unique method, on dualism as an ontology, and on Platonism as an ideology, challenged over two millenia ago by Aristotle and again by the Philosophes of the Enlightenment, has been further discredited by the same developments that brought down Newtonian positivism and ushered in the age of modern thought.
