Full Idea

Three periods can be distinguished in philosophical logic: the syntactic stage, from Russell's definite descriptions to the 1950s, the dominance of possible world semantics from the 50s to 80s, and a current widening of the subject.

Gist of Idea

Three stages of philosophical logic: syntactic (1905-55), possible worlds (1963-85), widening (1990-)
