William J Mitchell The Logic Of Architecture Design Computation And Cognition

The Logic of Architecture

"The Logic of Architecture is the first comprehensive, systematic, and modern treatment of the logical foundations of design thinking. It provides a detailed discussion of languages of architectural form, their specification by means of formal grammars, their interpretation, and their role in structuring design thinking. Supplemented by over 200 original illustrations, "The Logic of Architecture" reexamines central issues of design theory in the light of recent advances in artificial intelligence, cognitive science, and the theory of computation. The richness of this approach permits sympathetic and constructive analysis of positions developed by a wide range of theorists and philosophers from Socrates to the present. Mitchell first considers how buildings may be described in words and shows how such descriptions may be formalized by the notation of first-order predicate calculus. This leads to the idea of a critical language for speaking about the qualities of buildings. Turning to the question of representation by drawings and scale models, Mitchell then develops the notion of design worlds that provide graphic tokens which can be manipulated according to certain grammatical rules. In particular, he shows how domains of graphic compositions possible in a design world may be specified by formal shape grammars. Design worlds and critical languages are connected by showing how such languages may be interpreted in design worlds. Design processes are then viewed as computations in a design world with the objective of satisfying predicates of form and function stated in a critical language. William J. Mitchell is G. Ware and Edythe M. Travelstead Professor of Architecture at HarvardUniversity and a founder of the Computer-Aided Design Group in Los Angeles. Among the books he has authored or coauthored are "The Poetics of Gardens, The Art of Computer Graphics Programming, and "Computer-Aided Architectural Design."

The Logic of Design Process

What is the logic of design process? Departing from this question, Tiago da Costa e Silva investigates the characteristic feature of every projective activity, for instance, in architecture, design, engineering design, and in the arts. In opposition to predominant views that understand design processes as mechanical and deterministic, this study, with the help of the semiotics of Charles S. Peirce, characterizes design activities as continuous and serendipitous interplays of esthetic and abductive processes that define rules and manifest forms. Tiago da Costa e Silva concludes that invention and discovery, manifested in the form of processes of abduction, actively pervade every development in any given context of design process.
