‘But not that which has lost its soul is what is potentially alive’ – The Relation between Body and Soul in Aristotle

Abstract

The thus far little noticed element in Aristotle's definition of the soul – namely, its nexus to the particularities of a complex physical body (σῶμα φυσικόν / sôma physikon) – is the key to resolve three apparent inconsistencies of Aristotelian hylomorphism: First, the incompatible modalities of the assumed binding relation between physical body as a simultaneously functional matter and the soul as its form; second, the homonymy problem, i.e., that, according to Aristotle's own statement, a body’s remnant that was abandoned by its soul can only homonymously be called that which it was when it was alive; third, the problem that form in hylomorphism seems to be nothing but a configuration of material parts, which, though conceptualised in abstraction and independent from matter, would nevertheless add nothing new to the material composition in which it is instantiated. If that were so, how, then, can a hylomorphic theory conceive of form as ontologically separate from matter? Without a comprehensive and comprehensible resolution of those three major aporias – that is in line with today’s scientific conception of the world – Aristotle’s definition of the soul as form-without-matter would, in Ackrill's words, ‘resist interpretation’. This paper shows that such a resolution can in fact be achieved and that Aristotle’s hylomorphism allows for a plausible and consistent interpretation.
