Abstract

Our subject is the Aristotelian conceptions of induction (epagogé) and deduction (syllogism), their forms of operation and their logical connexions. We want to show that while deduction / syllogism is the only legitimate way of drawing inferences on an abstract level, it has no value for science if not based on universal premises, reached by induction. To date, inductive reasoning is criticized by lack of heuristic power. However, Aristotle had already pointed out the impossibility of vindicating all the assumptions of scientific discourse and therefore the nullity of an (im)possible "complete deduction". (AU)
