 The notion of logical construction had a great impact on the future course of analytic philosophy. One line of influence was via the notion of a contextual definition, or paraphrase, intended to minimize ontological commitment and to be a model of philosophical analysis. The distinction between the surface appearance of definite descriptions, as singular terms, and the fully interpreted sentences from which they seem to disappear was seen as a model for making problematic notions disappear upon analysis. Wisdom (1931) proposed this application of logical construction in the spirit of Wittgenstein. In this way the theory of descriptions has been viewed as a paradigm of philosophical analysis of this “therapeutic” sort that seeks to dissolve logical problems.
