Abstract

Thought of progress has been considered as one of the presuppositions of the West modernity. Having accepted this idea, we should regard it as one of the bases and foundations of early modern philosophy, and consider Descartes, known as the father of modern philosophy, as having a major role in its formation. There is a strong relationship between the West philosophical thought and the change of the idea of progress to one of the undisputed facts of the west civilization, and this issue can be seen clearly in Descartes thought system better than anywhere else. The present paper intends to show the leading position of Descartes’ thought system in the institutionalization of the concept of progress in the West philosophical system in three main parts: 1. Authority fighting and its relation with Cartesian’s Doubt, 2. The genuineness of the worldly life in Descartes’ thought system, and 3. Establishing the foundation of modern science. This article is based on the modern forerunners’ change of opinion about the philosophy mission in the world. It makes attempt to demonstrate in order to achieve the thought of progress, some prerequisites are necessary; and these prerequisite, though not exclusively, in their best and most complete form are generally achieved in the West philosophical thought and are particularly accomplished in Descartes’ philosophy.
