Once the philosophical works of Philodemus began to be edited and to come to the attention of scholars in the later 19th century, his influence begins to be seen, albeit sporadically. C. S. Peirce, who was impressed by Epicurean philosophy, especially the clinamen or ‘swerve’, studied Philodemus’ On Methods of Inference together with his student Allan Marquand, whose Ph.D. thesis included the first English translation of the book. It was apparently from Philodemus that Peirce took the term ‘semiosis’ in his characerization of semiotics as ‘the doctrine of the essential nature and fundamental varieties of semiosis’ (cf. Fisch [1971] 1986 and Deledalle 2001).
