Since Protagoras' classic “man is the measure of all things,” claims of relativism and counter-claims have been tendered. The nineteenth century saw Durkheim, Levy-Bruhl, Westermarck, Pareto, Marx, and others, suggesting that institutions, customs, moral codes, and the like, are “relative” both to the culture and to the time. At the crest of this wave of “relativism” surged a vicious claim: that truth and knowledge itself were merely functions of particular conditions. The “validity” of knowledge was said to be at the (...) whim of historic, social factors. Not only is no theory really true; no particular statement is ever so. Not only is no theory or statement really true; no theory of knowledge has thus far ever been free from the bias of its genesis. There have been no absolute insights for epistemology. Or so, at least, it was claimed. (shrink)

In a recent paper I criticized the pragmatist theory of truth from the frame of reference of modern logical positivism. By showing the similarity between Karl Mannheim's claims of epistemological relevance for sociology of knowledge and certain pragmatist notions concerning truth I made criticism of the latter with the former. The aim of this present paper is to extend and elaborate upon those critical remarks regarding pragmatism both in order to answer objections raised since and to clarify what was said (...) there. Moreover, the evaluation of the pragmatist theory of truth may have been surprising to some since so much lately has been made of the points of agreement between pragmatism and modern positivism. It is thus also my intent to delimit agreements and disagreements and compare the respective emphases in pragmatist and positivist thought concerning the nature of truth. (shrink)
