GREGORY L. MURPHY, The big book of concepts. Cambridge, MA: MIT Press, 2002. Pp. 563. ISBN 0-262-13409-8

[...]the psychology of concepts has grown ever more diverse, unable to nd a common ground on which to consign the accumulation of empirical and developmental evidence and theoretical notions. [...]the knowledge approach complements both the prototype and exemplar accounts; yet, in its current form, it is able to imply little more than a nonspecic adjunct to these theories. [...]Murphy argues for language as merely a reection of conceptual structure, thus conforming to domain-general conceptual universals. Murphys vision of the future is that a distinct knowledge approach will be subsumed under a broader model in which all theories of concepts will include knowledge eects, and the theories will dier in terms of their mechanisms for how knowledge is involved in processing (p. 498). [...]the book comes full circle: the most comprehensive theories of conceptual phenomena are seriously lacking with respect to mechanisms by which such inclusive processing is accomplished; yet it is just such all-encompassing viewpoints that are required to explicate and unify conceptual theory.
