I came to this thanks to the Politics and Matter research group (Geographical Science, University of Bristol) blog.
In the interview, the subject of individuation is touched upon and briefly articulated. This is central to Simondon’s philosophical project as a theorisation of a metastable and pre-individual “more-than-one”, as explained in the aforementioned biography.
Muriel Combes excellent introduction to Simondon’s work “Gilbert Simondon and the philosophy of the transindividual“, recently translated for MIT Press, has been reviewed by David Scott on NDPR. It is a detailed and useful review and offers some insights into Simondon’s work in its own regard, well worth a read if you’re interested.
