For the history of Greek literature, philosophy, from Aristotle onwards, is important in at least three different ways. First, style and genre: the literary presentation of philosophy, sometimes within the same writer, varies on a scale which may range from what is little more than technical shorthand to highly polished prose. Some philosophers of the Hellenistic period even present their ideas in verse, and quotations, especially from the most famous poets, are not uncommon.

Secondly, literary theory: Aristotle himself, and some later Greek philosophers, made fundamental contributions to the theory of rhetoric and to literary criticism. Much of their work in this field was taken over by later classical writers, especially the Roman rhetoricians, and it has had a continuing influence.

Thirdly, thought. This must be considered when it directly influences the subject matter of literature. In this respect Aristotle is much less significant than the Stoics and Epicureans. The philosophy of Epicurus is Lucretius' theme and Lucretius is a poet of comparable genius to Virgil. But Lucretius is only the most notable of many poets and other writers whose work was strongly influenced by Epicureanism or Stoicism. Today that influence looks decidedly more marked on Roman literature than on Greek. But this is due, at least in part, to the loss of nearly all Greek literature from the last three centuries B.C. There can be little doubt that Stoicism and Epicureanism had a pervasive influence on later Greek culture.
