The aim of this paper is to critically examine the Ryle’s conception of “Descartes Myth”. Ryle has two objectives in his book The Concept of Mind: (i) to refute a current philosophical theory about mind. (ii) to substitute at least in blue print, a satisfactory alternative. This paper gives a descriptive analysis of what Ryle calls Descartes-Myth and arguments for it. Conclusion of this paper drawn as he does not succeed in dispelling the myth but only substitutes a peculiar logical monism for Descartes’ Myth.
