Abstract

"The aim of this paper is to inscribe the argument on the Practical Syllogism of De motu animalium, chapter 7, in its immediate context. Now this framework is by no means a logical one. The De motu is a psychological or zoological treatise, whose scope belongs to natural philosophy. Moreover De motu's Practical Syllogism cannot be restricted to practical, i.e. anthropological, cases, like akrasia. It is inserted in a physiological development regarding the biological explanation of animal emotions, reactions and actions. Thus, the necessity of the conclusion – here the action itself – does not mean that the conditions for acting are reducible to propositions or to logical connections: rather it stands for the necessity that governs the agent-patient relation in animal movement."
