Πλωτίνος (Plotinus) was a prominent philosopher in the 3rd century CE, known for founding the philosophical system called Neoplatonism. He emphasized the existence of a single source of all reality, referred to as the One, from which everything emanates. His ideas sought to reconcile the teachings of Plato with other philosophical traditions, focusing on the nature of existence and the soul. His works, compiled in the Enneads by his student Porphyry, explore themes such as the nature of the divine, the process of creation, and the journey of the soul towards unity with the One. Plotinus' influence extended through the centuries, impacting both Christian and Islamic thought.
