Antipsychologism was adopted in semantical analysis at the turn of the 20th century. This might be seen as an advance in the development of European rationalism: it signified an isolation of semantic phenomena and helped analytic philosophers capture the specific structure of semantic relations; then-work was done by the end of the first half of our century. However, already at the beginning of the century some undesirable consequences of the antipsychologistic tendency became apparent. I dare to conjecture that it was because of the antipsychologistic paradigm that new semantical antinomies appeared: Antipsychologistic semantics could not find a solution for the new as well as for the old semantical paradoxes, demonstrating that antipsychologism is an idealistic simplification.
