on describing it further, we must call the One a sheer potentiality (dynamis) without which nothing could exist. (III.8.10) As Plotinus explains in both places and elsewhere (e.g. V.6.3), it is impossible for the One to be Being or a self-aware Creator God. At (V.6.4), Plotinus compared the One to "light", the Divine Intellect/Nous (Νοῦς, Nous; first will towards Good) to the "Sun", and lastly the Soul (Ψυχή, Psyche) to the "Moon" whose light is merely a "derivative conglomeration of light from the 'Sun'". The first light could exist without any celestial body. The One, being beyond all attributes including being and non-being, is the source of the world—but not through any act of creation, willful or otherwise, since activity cannot be ascribed to the unchangeable, immutable One. Plotinus argues instead that the multiple cannot exist without the simple. The "less perfect" must, of necessity, "emanate", or issue forth, from the "perfect" or "more perfect". Thus, all of "creation" emanates from the One in succeeding stages of lesser and lesser perfection. These stages are not temporally isolated, but occur throughout time as a constant process. The One is not just an intellectual concept but something that can be experienced, an experience where one goes beyond all multiplicity. Plotinus writes, "We ought not even to say that he will see, but he will be that which he sees, if indeed it is possible any longer to distinguish between seer and seen, and not boldly to affirm that the two are one." Emanation by the One Superficially considered, Plotinus seems to offer an alternative to the orthodox Christian notion of creation ex nihilo (out of nothing), although Plotinus never mentions Christianity in any of his works. The metaphysics of emanation (ἀπορροή aporrhoe (ΙΙ.3.2) or ἀπόρροια aporrhoia (II.3.11)), however, just like the metaphysics of Creation, confirms the absolute transcendence of the One or of the Divine, as the source of the Being of all things that yet remains transcendent of them in its own nature; the One is in no way affected or diminished by these emanations, just as the Christian God in no way is affected by some sort of exterior "nothingness". Plotinus, using a venerable analogy that would become crucial for the (largely neoplatonic) metaphysics of developed Christian thought, likens the One to the Sun which emanates light indiscriminately without thereby diminishing itself, or reflection in a mirror which in no
