Abstract
The aim of the paper is to outline a reflection on the fact that the emergence of the autonomy of psychology cannot be understood except as a specific, tortuous and paradoxical destination of some modern unfoldings of Western philosophical thought. In order to do this, the argumentation will take as initial problem the lapse of two centuries that takes place between the Galilean rudiments of the law of inertia and the first transpositions of the methodology of mathematical physics to psychological phenomena. The paper will thereby follow two movements: 1- A first step is devoted to some philosophical aspects associated with the conditions of the emergence of modern psychology; 2- A second step will allude to two contemporary diagnostics - one by G. Canguilhem, another by M. Foucault - of its ideological and epistemological situation.
