The author presents an epistemic logic with quantification, formulated in terms of consistency in model systems. To support results like "a knows p, and p implies q, therefore a knows q," consistency of a set of statements is reinterpreted as defensibility, or immunity to criticism. Perspicuous informal analyses, such as the remarks on the role of pronouns, augment the book's philosophical value.--N. A. G.

Ten lightweight but stimulating essays in what Bruner calls protopsychology, the study of psychology's sources of ideas. His topics range from the teaching of mathematics to the nature of myth.--N. A. G.

An imaginative, though at times obscure, inquiry into the nature of method. The setting is dialectical: Buchler elucidates what is methodic about method by examining the views of Bentham, Coleridge, Descartes, Bacon, Dewey, and Whitehead. The concluding exposition of method as "a power of manipulating natural complexes, purposively and recognizably, within a reproducible order of utterance" is suggestive but vague.--N. A. G.
