Abstract

A central theme to be found in Dewey’s writings is his criticism of theories of knowledge proposed throughout the history of Western philosophy. None of the once familiar “isms,” whether it be a variant of empiricism, rationalism, or idealism, escaped Dewey’s scrutiny. And each in its turn proved to be unacceptable to Dewey, because it was found that each rested upon what Dewey referred to as “the philosophical fallacy,” namely “the conversion of eventual functions into antecedent existence,” or the fallacy of selective emphasis. Basically, this fallacy amounted for Dewey to the emphasis of one aspect of scientific inquiry to the exclusion of the rest, and taking the features characteristic of that aspect as paradigmatic for the purpose of accounting for knowledge. Thus, for example, advocates of what Dewey called sensationalism, for whom knowledge was to be explicated in terms of an immediate acquaintance with a perceptual given, emphasized an aspect of scientific inquiry, viz., that inquiry is engaged in only when some given situation is problematic, without regard to the fact that even those features of a problematic situation, which are taken to be given and stable features for purposes of resolving the problem, are so taken only provisionally, depending upon whether the ensuing inquiry is successful in resolving the problem at hand.
