Tracing influences is important, but the relationship between two thinkers cannot be just an influence. Because, all influence is retrospective. We are rather dealing with the resumption of a speculative gesture that engages and continues. Tarde’s metaphysical partisanship is so considerable that by reading it one can no longer detach Bergson from a striking vision that begins below him. With the pretension of grasping the continuity of the same gesture of thought between these two authors, we will approach, in the present text, the psychomorphism of Tarde, with his assumption of a division of nature and some of its consequences on Morality and mysticism, in what seems to us, they are not without consonance with Bergsonism.
