The Wittgensteinian thesis that “the result of philosophy is not a number of ‘philosophical propositions,’ but to make propositions clear” has been given various interpretations by subsequent philosophers. Thus, for example, certain British philosophers have confined themselves to the analysis of colloquial language and have developed great skill in sophistical demonstrations intended to show that there is no such thing as a philosophical problem. Another group of philosophers considers language solely as a phenomenon of human behavior and attempts to clarify confusions and misunderstandings within language by utilizing the statistical techniques of contemporary behavior psychology. Still other philosophers, under the impact of logical positivism, have maintained that the clarification of propositions entails the construction of a language with precise rules of formation, transformation, and reference into which one could translate all the non-contradictory portions of ordinary spoken language.
