Abstract

In this article my main aim is to illuminate the development of conception of phenomenon in a general perspectivethe. For this aim I referred to the Platonian demarcation between forms and sensory world. I tried to show that there is a similarity between Platonian dualism and Deacartes dualism if we read Plato following Descartes. But we know that such a distinction between two kind of entities has kept busy a lot of philosophers in history of philosophers. Accepted that the submission of conception of phenomenon to philosophy has achieved by Plato, the real term meaning has been gained during the period of Kant. Also in the contemprary philosophy Brentano and Husserl has dealt with this conception to a certain extent
