Abstract

An examination of four types of logico-mathematical formalisms, conceived as attempts to avoid paradoxes, leads to the conclusion that there can be no general, formal criterion of nonsense. Crahay holds that formal systems must be treated as dynamic, as the not-fully-formalizable becoming formal, the "conceptual" becoming "notional." Though technically competent and based on a vast amount of material, the treatment is too diffuse and sketchy to be more than suggestive.--L. K. B.
