Empedocles

Empedocles (; Ancient Greek: Ἐμπεδοκλῆς; c. 494 – c. 434 BC, fl. 444–443 BC) was a pre-Socratic Greek philosopher and a native citizen of Akragas, a Greek city in Sicily. Empedocles' philosophy is known best for originating the cosmogonic theory of the four classical elements. He also proposed forces he called Love and Strife which would mix and separate the elements, respectively.

Empedocles challenged the practice of animal sacrifice and killing animals for food. He developed a distinctive doctrine of reincarnation. He is generally considered the last Greek philosopher to have recorded his ideas in verse. Some of his work survives, more than is the case for any other pre-Socratic philosopher. Empedocles' death was mythologized by ancient writers, and has been the subject of a number of literary treatments.
