To meet a dilemma between the axiomatic theory of demonstrative science in Posterior analyticsand the non-aximatic practice of demonstrative science in the physical treatises, Jonathan Barnes has proposed that the theory of demonstration was not meant to guide scientific research but rather scientific pedagogy. The present paper argues that far from contributing directly to oral instruction, the axiomatic account of demonstrative science is a model for the written expression of science.The paper shows how this interpretation accords with related theories in (...) the Organon, including the theories of dialectic in Topicsand of deduction in Prior analytics.

For the past three decades the theory of supposition (suppositio) has been a crux of scholarship in Medieval logic. Although supposition was one of the banner doctrines of the logic modernorum, its nature and purpose have remained elusive to modern interpreters. In this paper I outline an alternative approach to supposition theory. (edited).
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.
