Abstract
A correct understanding of what Freud means by “pleasure” and what he thinks of the possible ways to obtain pleasure requires an examination of his conceptions of the drive and of the libidinal body. Both theories are built on a variety of traditional philosophical views, the examination of which can help to overcome some of their obscurities. The reference to Leibniz and his Aristotelian understanding of the relation between pleasure and the force (vis activa) which animates the substance and maintains it in constant movement allows an account of what in the drive preserves it from total exhaustion and a consequent reversal of pleasure into displeasure. Similarly, an examination of Schopenhauer's conception of the human body clarifies what Freud says about the “pleasure of the organ”. The necessity for the drive to invest a body is given thereby a metaphysical foundation. Furthermore Schopenhauer's phenomenological description of the manner in which this driven body is experienced differently in the affect of pleasure or displeasure, and in an objective representation sheds new light on the relation between the libidinal body and the objective body
