Why do philosophers never step outside books [“texts”]?
Take William G. Lycan’s paper ‘The Continuity of Levels of Nature’. It includes fifty-two references to other philosophers’ texts. Jaegwon Kim’s ‘Supervenience as a Philosophical Concept’ has fifty-one such references. On the other hand, Geoffrey Bennington’s paper, ‘Derrida’, has three references to texts by other philosophers (other than those by Derrida himself).
