This volume brings together papers originally presented at a seminar series on Speculative Grammar, Universal Grammar, and Philosophical Analysis, held at the University of Bologna in 1984. The seminars aimed at considering various aspects of the interplay between linguistic theories on the one hand, and theories of meaning and logic on the other. The point of view was mainly historical, but a theoretical approach was also considered relevant. Theories of grammar and related topics were taken as a focal point of interest; their interaction with philosophical reflections on languages was examined in presentations dealing with different authors and periods, ranging from the Middle Ages to the present day.
