Aristotle's dense philosophical system can be summarized as follows:
Ontology - Teleological Realism (a.k.a. "Materialism")
Epistemology - Empiricism with Logical Classification (via the "Four Causes")
Ethics - Virtue as Active Excellence (Eudaimonia, "Flourishing")
Explain ONE of these three concepts in your own words, comparing or contrasting with another philosopher (Plato is the obvious choice, but Buddha and Heraclitus would be interesting too).
Remember, if you need help, see the NOTES AND LINKS page (under the Philosophy tab above): there are videos on Aristotle, notes on the earlier philosophers, and a PowerPoint on Socrates/Plato plus one on "Ancient Ethics" that might be really useful for jogging your memory!
