A Selection from the Discourses, with the Encheiridion

Reading companion and full text of A Selection from the Discourses of Epictetus, with the Encheiridion, translated by George Long — drawn from Long's complete 1877 translation and presented here in the 1890 G. P. Putnam's Sons edition, gathering the most essential of the surviving discourses alongside the complete Encheiridion, the brief handbook of Stoic principles that Arrian distilled from his teacher's classroom and that has never ceased to be read.

Parts of Animals · Movement of Animals · Progression of Animals

Reading companion and full text of Aristotle's Parts of Animals, Movement of Animals, and Progression of Animals (Loeb Classical Library 323), translated by A. L. Peck and E. S. Forster — three of Aristotle's major biological treatises: the first an enquiry into the bodily parts of animals and the teleological principles that govern their design, the second a short but philosophically rich analysis of the causes of animal locomotion in general, and the third a systematic study of how different kinds of animals actually move.
