This work proposes to revisit the principal concept of Bergson's philosophy : la durée. Firstly, la durée is a special number. Jankélévitch and Deleuze think that la durée of consciousness has only quality properties, but, in fact, the real time for Bergson is not a form without numerical dimension. Secondly, the signification of la durée is moral. Deleuze and Henri Gouhier think that the finality of life, for Bergson, is the innovation, the creation, (love of creation) but, in fact, the finality of life is the construction of a fraternal society (creation of love).
