The teaching of Plotinus was dictated to Porphyry, who in 301 AD, probably influenced by the Pythagorean arithmetic, regrouped the fiftyfour tracts into six groups of nine, hence the title: the Enneads (Greek Ennea, nine). These six groups correspond to the six stages of spiritual purification. The first deals with the moral Ennead (the first step of purification), the second and third of the physical world and show the vanity of material things. The fourth is the Soul of the world, the Spirit of the fifth, and sixth on the One. Porphyry played a significant role in the evolution of thought in late antiquity and throughout the Middle Ages. The way he has systematized and explained the thought of his master Plotinus, has given birth to a spiritualism Augustine distributed throughout the Latin West.
