Chris Watkin translates an interesting passage from Serres’s thesis on Leibniz (1968), here.
Two things I notice. First, the teleological structure of the historical interest. Serres’ thesis is of interest because of what he will become. Second, the comments on the line – these are very close to comments by Derrida (published a year before), a propos both Leibniz and ‘evolutionary’ thought in André Leroi-Gourhan, specifically about the effect that ways of thinking have affinities with certain representations (eg, a line) of time.
