PLOTINUS

Plotinus was a Greek philosopher born in Roman Egypt, most likely in Lyco (modern Asyut) or Lycopolis. He is widely recognized as the founder of Neoplatonism, a philosophy that profoundly influenced late antiquity, the Middle Ages, and the Renaissance. Plotinus began studying philosophy in Alexandria at age 28, becoming a devoted student of Ammonius Saccas for eleven years. He joined Emperor Gordian III’s Persian expedition in 243 CE, after which he settled in Rome, where he taught and wrote for over 25 years. His teachings attracted a circle of students and admirers, including his most famous pupil and biographer, Porphyry, who later edited and published Plotinus’s works as the Enneads. Plotinus’s philosophy centers on three fundamental principles: the One (the ultimate source of all reality), the Intellect (Nous), and the Soul. He emphasized the soul’s ascent toward the divine and the unity underlying all existence. His life and thought are primarily known through Porphyry’s Life of Plotinus, which presents him as a figure of remarkable spiritual and moral integrity, largely uninterested in material concerns or personal fame.
