Plotinus (c. 204-270) is often accredited as the founder of Neo-Platonism. In an attempt to revive Platonic thought, this 3rd century philosopher and mystic wrote about issues such as virtue, happiness, reason, body, and soul, with Plato's philosophy as his guide. Plotinus located the source of creation in a supreme ‘One’. Plotinus believed this "One" transcended being, non-being, multiplicity and division.
