In his main work, L"individuation à la lumière des notions de forme et d"information, Gilbert Simondon displayed a theory of the discontinuous processes of individuation (or "ontogenesis") from which structures emerge. Linking the concepts of singularity and historicity through the paradigmatic assumption of quantum physics, Simondon attacked both determinism and indeterminism by way of an original critique—neither empiricist nor idealistic—of the concepts of substance and cause.
