24.200: Ancient Philosophy Prof. Sally Haslanger November 29, 2004 Ancient and Hellenistic Philosophers Epicureanism is one example of a philosophical "school" which flourished in the Hellenistic Age (323-31bc), ie., from the death of Alexander to the victory of Octavian (aka Augustus) over Mark Antony at the battle of Actium. (Roman Empire established by Augustus in 30bc.) It will help to get a broad sketch of the philosophical community of Athens, to place Epicurus within it.

Commentators, etc. Alexander of Aphrodisias (end of 2nd c. AD)Diogenes Laertius (3rd century AD) Galen (129-200ad) After Plato's death, Aristotle left Athens for 12 years, returning to Athens in 335. Probably this is the time during which he did most of his biological work. When he returned he taught not in the Academy, but in the Lyceum, a grove just outside of the civic boundaries of Athens. After Aristotle's death in 322, Theophrastus established the Lyceum as a school and carried on Aristolte's teaching. i) Hellenistic philosophy aimed to make itself available to a wider group than Plato and Aristotle's teaching. ii) Ethical values became removed from social status and nationality, rejecting traditional attitudes; individual well-being could be achieved by one's inner resources; human rationality could provide the basis for a tranquil and happy life. Emphasis on search for happy, tranquil life. Some‘ commentators link this to increasing instability in greek world, others to a sense of the breakdown of small community life... iii) Scope of hellenistic philosophy narrower; special sciences, history, literature, geography, etc. separated off...mostly moved to Alexandria. II. Epicurus Epicurus set up a community near Plato's academy. It was more like a monastery than like a school, -- individuals committed to a certain form of life; women and slaves were admitted. Called "the garden". He wrote over 300 rolls (books), 37 of them included in the work "On Nature". Very little is left, virtually all of it is in the text. Much of our knowledge of Epicurus's views gained through Lucretius who lived and wrote 200 years later. Lucretius's life and character are virtually unknown to us. 2 concerns Fear of and fear of divine action/intervention were two major obstacles to leading a tranquil and happy life. These fears should be combatted by understanding of the real causes of things. If we understand accurately our place in the world, such fears will dissolve. Epistemology empiricist, ie., the senses and immediate feeling are the foundation for all knowledge. Metaphysics materialist/atomist, ie., ultimately the world consists of atoms and the void. Ethics hedonist, ie., pleasure is the only thing which is good as an end. Contrast with Socrates, Plato and Aristotle Socratesskeptical about knowledge, no metaphysics, ethics divorced from pleasure? the senses provide no knowledge; what is real is not material -- only the forms are real; pleasure is not intrinsically good. Aristotle the senses work together with nous; what is real is a composite of matter and form; pleasure accompanies virtue and happiness which are the supreme good. Common ground ethical objectivism; supreme good/virtue grounded in human nature, ie., what we are, and what leads to our flourishing. Also, with P and A non-skeptical -- knowledge of reality is possible. III. Epistemology A. Relevant quotes Lucretius, p. 39-40 "If a belief resting directly on this foundation [of the senses] is not valid, then there will be no standard to which we can refer any doubt on obscure questions for rational confirmation." Epicurus, letter to Herodotus 38b "We must use our sensations as the foundation of all our investigations; that is, we must base investigations on the mental apprehensions, upon the purposeful use of the several senses that furnish us with knowledge, and upon our immediate feelings. In these ways we can form judgements on those matters that can be confirmed by the senses and also on those beyond their reach." Also Epicurus Letter to Herodotus 80 "We must search for the causes of celestial phenomena and in general of that which cannot be clearly perceived by
