Abstract

The past 25 years have seen an increasing interest in later medieval logic and in the theory of supposition. a review of literature reveals, however, wide differences of interpretation of supposition-theory. taking the theory in the widest sense as a contribution to semiotic or the theory of signs, this study shows how supposition has been variously treated as a syntactical, semantical and even pragmatical theory. the main views of p. boehner, e. moody, p. geach, d. p. henry, w. c. kneale and l. m. de rijk are examined, compared and appraised with respect to overall progress in the elucidation of supposition-theory
