Abstract
Michel Henry recognized himself within Maine de Biran’s work, while rejecting the French spiritualistic tradition to which this one was attached. However, without occulting the great differences which separate him from this tradition, it seems that we find in Bergson’s first book, more than in Maine de Biran, the premises of an ontological dualism, such as he supported, which announces an authentic philosophy of the conscience, beyond any intentionality. In return, as if Michel Henry had emphasized a tendency already present in Time and Free Will, we could read again Bergson’s first book in the light of material phenomenology itself.
