Much of the cognitive lies beyond articulate, discursive thought, beyondthe reach of current computational notions. In Sketches of Thought, Vinod Goelargues that the cognitive computational conception of the world requires our thoughtprocesses to be precise, rigid, discrete, and unambiguous; yet there are dense, ambiguous, and amorphous symbol systems, like sketching, painting, and poetry, foundin the arts and much of everyday discourse that have an important, nontrivial placein cognition.Goel maintains that while on occasion our thoughts do conform to thecurrent computational theory of mind, they often are -- indeed must be - vague, fluid, ambiguous, and amorphous. He argues that if cognitive science takes theclassical computational story seriously, it must deny or ignore these processes, orat least relegate them to the realm of the nonmental.As a cognitive scientist with adesign background, Goel is in a unique position to challenge cognitive science onits own territory. He introduces design problem solving as a domain of cognitionthat illustrates these inarticulate, nondiscursive thought processes at work throughthe symbol system of sketching. He argues not that such thoughts must remainnoncomputational but that our current notions of computation and representation arenot rich enough to capture them.Along the way, Goel makes a number of significantand controversial interim points. He shows that there is a principled distinctionbetween design and nondesign problems, that there are standard stages in thesolution of design problems, that these stages correlate with the use of differenttypes of external symbol systems; that these symbol systems are usefullyindividuated in Nelson Goodman's syntactic and semantic terms, and that differentcognitive processes are facilitated by different types of symbol systems.A BradfordBook
