About the author

Born in Tyre around 234 CE and later active in Rome, Porphyry was a Neoplatonic philosopher best known as a student of Plotinus. He edited and published the Enneads, the collection that carried Plotinus's thought into later generations, and he also wrote a Life of Plotinus that remains an important source for his teacher's career.

Porphyry wrote on an unusually broad set of subjects, including philosophy, logic, religion, and ethics. His Isagoge, an introduction to Aristotle's Categories, became hugely influential in the Greek, Arabic, and Latin traditions and helped shape medieval discussions of logic and universals.

He is also remembered for works that show how seriously he connected philosophy with the way a person should live. Texts such as On Abstinence from Eating Animals present a vision of intellectual and moral discipline, while other surviving writings reveal a sharp, questioning mind engaged with the religious debates of his time.
