Abstract

These essays "develop in a more ample and emphatic form the pragmatic perspective of the idealistic position" defended in previous books. The basic question deals with validating the criterion employed in the practice of determining factual truth. The pragmatic thesis is defended along the criterial rather than propositional line. Criterial pragmatism asserts "that a proposition is to be accepted if it conforms to an epistemologically warranted criterion, and that a criterion is warranted if its adoption as a principle of propositional acceptance is maximally success-promoting." It is concerned with validating methodology rather than establishing substantive theses or validating specific criteria for factual knowledge. "Since the rational espousal of a factual truth must be governed by some appropriate criterion of acceptance, and any such criterion is in effect methodological, it follows that in the factual domain practical reason is basic to the theoretical."
