Epistemic Dimension of Reason from Aristotle's Point of View

The present article is a survey on Aristotle’s view on reason in two spheres: theory of knowledge and theory of self. In the theory of knowledge, it is explained that, according to Aristotle, the mechanism of knowing has four phases: sense, recall, experience and idea. According to Aristotle, idea is rational knowledge that is derived from the three pervious phases. In this context, Aristotle’s famous saying which reads anyone who has no sense has no knowledge makes sense. In the sphere of self, first the meaning of self from Aristotle’s point of view is explained. Then it is concluded that reason is a power of self which is in charge of the four phases of knowledge. In the end, the passive reason and active reason are discussed in detail and a critique of the well-known interpretation of active reason as reason separate from man is presented.
