The Argument From Relatives

Show Summary Details


In his commentary on Metaphysics A 9 Alexander of Aphrodisias describes a number of Platonist arguments for Forms, drawing upon Aristotle's now lost work Peri ideȏn. The chapter is a detailed examination of the most complex of these Platonist arguments, the so‐called ‘Argument from Relatives’. It is shown that this argument is best understood as a reductio ad absurdum of anti‐Platonism. The anti‐Platonist's rejection of a paradigmatic Form of Equal commits him to the claim that equality is predicated of the sensible equals homonymously. If he is to avoid this unwelcome consequence, he must grant the existence of the Form.
