If the events of the world are, in Lachelier's words, a network of general properties standing at the point of intersection of functional relations which, in principle, enable the analysis of the former to be carried through, and if the body is indeed a province of the world, if it is that object which the biologist talks about, that conjunction of processes analysed in physiological logical treatises, that collection of organs shown in the plates of books on anatomy, then my experience can be nothing but the dialogue between bare consciousness and the system of objective correlations which it conceives.
