• Study I: Aristotle on sign-inference and related forms of argument ; Study I Appendix A: The text of Rhetoric, II 25, 1403a6-10 ; Study I Appendix B: Were there other developments in Aristotle's rhetorical theory? ; Study II: Rationalism, Empiricism, and Scepticism: Sextus Empiricus' treatment of sign-inference ; Study III; The Stoics on sign-inference and demonstration ; Study III Appendix: The evidence for a Dialectical origin of the Stoic theory of signs ; Study IV: Epicurean sign-inference in Philodemus ; Conclusion

Review from previous edition This excellent book provides a number of new historical and exegetical takes on an important chapter in Hellenistic epistemology. Allen's ideas will be at the centre of future debates in the field. His arguments are not conclusive, and the reader may not find them all convincing, but such is the nature of Hellenistic epistemology.
