This essay shows the logical interpretation of the perception in Peirce to highlight Leibniz’s influence on the conception of associative representation. This influence conditions Peirce’s interpretation of Kant’s intuitive apprehension and initiates the interpretation of the individual as essentially relational. That concept is deepened by Peirce’s studies on the logic of relations and even more on the logic of continuity. The relational individual is the key concept for a possible social-political interpretation of the continuous by Peirce. The relationship between individual (...) and continuous, based on the notions of possible and relation, offers the model to conceive the ego as originally social. The relational nature of the individual is also analysed with reference to the doctrine of chances. In this context, it emerges clearly the relationship of logic with society and with Peirce’s political conceptions. This paradigm can also be traced back to the analyses by Leibniz (studies of natural law). (shrink)
