This article explores Aristotle’s theory of pleasure in relation to the theories he has in mind when he constructs his own theory. This article examiNEs how and to what extend his theory deals with the so-called process theory of pleasure, which was Aristotle’s main target, especially by defining pleasure as the activity of the natural state. This article also scrutinizes the distinction between movement and activity, what is the main theoretical tool he uses in attacking the process theory, addressing some difficulties in the distinction and considering whether these difficulties cause trouble to his theory of pleasure itself. Finally, this article discusses the implications of Aristotle’s presentation of pleasure as a kind of end and his conception of proper pleasure in relation to the criticism of hedonism.
