In this paper, I try to show how epagōgē is related to the actions of nous, and furthermore to the kind of calculative (λογιστικὴ) or deliberative (βουλευτικὴ) phantasia analysed by Aristotle in De Anima. By examining the role, whichAristotle attaches to the epagōgē, nous and phantasia, I conclude that the Stagerite philosopher didn’t mean to identify epagōgē merely to a process of systematic correlation of the empirical facts. Experience finds its deserved place inAristotle’s epistemological system, but it is the mind’s actions that lead us to discover the new and the novel. Among them phantasia has a distinguished constructive role. Aristotle in his logical treatises describes the classic theory of syllogismōs and the less systematic theory of epagōgē. Transcribing, however, the argument from the field of logic to one of the epistemic process within Aristotle’s philosophy, I argue that in the light of De Anima, and specifically at those points where the philosopher mentions the power of the mind to imagine and infer, Aristotle’s model of knowledge is better explained, and the epistemic character that the philosopher attributed to the meaning of epagōgē, nous and phantasia is demonstrated in a more complete way.
