Brentano's Argument against Aristotle for the Immateriality of the Soul

The Aristotelian conception of the soul as Brentano understood it is examined, with respect to the nature of the soul and mainly to what Aristotle called the sensitive soul, since this is where the issue of the soul's corporeity becomes important. Secondly the difficulties are discussed which Brentano saw in the Aristotelian semi-materialistic conception concerning the intellectual, as distinct from the sensitive soul from Brentano's reistic point of view which and that it is an immaterial substance. Finally there follows a presentation of what is taken to be Brentano's conception of the soul as it appears from a reistic interpretation of his analyses of the act of sensation and of the subject of sensation in order to shed some light on the reistic ontology that may be taken to underlie Brentanos's psychology.
