Phenomenology and Psychology

L’origine et les fondements de la question cartésienne chez Heidegger

Showing a very early interest in Descartes, after having first considered him as a Christian thinker in the perspective of a deconstruction of religious life, Heidegger soon regards him as the major obstacle to the phenomenological analyses he wants to develop, as part of the first ontological search he gave himself: that of a hermeneutics of facticity. Therefore, the latter immediately takes in his work the shape of a hermeneutics of the I think, therefore I am, its author being blamed for having entirely ignored the sense of being in the I am, focused as he is on the thinking ego, the ins and outs of which he develops. But the criticism also applying to Husserl, it is by laying the blame on his master, that Heidegger intends to radicalize the project of his own master, hence the necessity to throw light on the origin and the foundations of what we can call the Cartesian question in Heidegger.
