Plotinus (c. 204/5–270 AD) was a prominent philosopher in the ancient world, best known as the founder of Neoplatonism. His teachings were heavily influenced by Plato, yet he introduced innovative concepts that profoundly shaped later philosophical and theological thought. Plotinus was born in Lycopolis, Egypt, and studied in Alexandria before relocating to Rome, where he taught and wrote most of his works. His philosophy emphasized the concept of the One, from which emanated the Intellect and the Soul, forming a triadic structure that explained the nature of reality and existence. His Enneads remain a seminal work in the field of metaphysics.
