He also took a lively interest in nascent Freudian theory and its uses before eventually distancing himself from it. His posthumous work, Elementary Principles of Philosophy (Principes Élémentaires de Philosophie) based on notes taken by his followers, was the first work banned by the fascist military regime established in Turkey in 1980. Quotations As much as one might say: there are, in the history of philosophy, philosophies without subject and philosophies which exhaust themselves in a debauchery of honest or pharisean artifice, with perfect unawareness of being without substance, one will not discuss more than the dates; as much as one might say: the rebirths of the spirit correspond to the discovery of a new subject and the nuances are then swept away because one poses problems in grander terms; they will congratulate us on the ingeniousness of our designs.
