Axiomatization, demonstration, and analysis of On the Heavens

Abstract

I examine On the Heavens (DC) I 2 in order to show there the presence of scientific demonstration. This development tries to contribute new evidence in favor of the not discrepancy between theory and scientific practice in Aristotle (Barnes, 1969) and to make the interpretation that method real and solely used is dialectic relative (whose precedent goes back to Owen, 1980). In addition, following the hermeneutic proposal of Gotthelf (1987) and Detel (1993 and 1997), I will show how scientific demonstration is used in the proof of simple body (ether) existence. I will offer also a reconstruction of the proof by means of the elaboration of a scheme that includes the set of deductions. The latter developments constitute the most new contribution of the present paper.
