La Philosophie comme manière de vivre (2001)
Incommensurables donc, mais aussi inséparables. Pas de discours qui mérite d’être appelé philosophique, s’il est séparé de la vie philosophique, pas de vie philosophique, si elle n’est étroitement liée au discours philosophique. C’est là d’ailleurs que réside le danger inhérent à la vie philosophique: l’ambiguïté du discours philosophique.
