Le jeu cognitif du muthos et logos chez Platon
This paper aims to propose a review of the relationship between mythos and logos in the work of Plato, from the complex use of those two words in the preamble to the Timaeus, the prologue of book 9 of the Politeia and the pseudo-digression of the Politicus on the need for a change of method. The analysis of these passages reveals that mythos, far from opposing the logos as a radically incompatible discourse, or even far from being the matrix which must escape the logos, appears as a kind of logos specializing in the representation of a reality which is imaginary and invisible. Speech of phantasia for the intellect, the myhos helps get closer to the truth, even to correct errors in logic. The presentation of the Atlantis myth - the most horrible myth of classical mythology - and of the myth of Cronos shows fully the double postulation of mythical discourse, sometimes turned to fiction, sometimes as if to objective reality.
