Seven Key Elements of what has been called Platonism or Neoplatonism Neoplatonism began as a complex (and in some ways ambiguous) philosophy and grew vigo- rously in a variety of forms over a long period; it is therefore not easy to generalize about it. But the leading ideas in the thought of philosophers who can properly be described as Neoplaton- ists seem always to have included the following: 1. There is a plurality of levels of being, arranged in hierarchical descending order, the last and lowest comprising the physical universe, which exists in time and space and is perceptible to the senses. 2. Each level of being is derived from its superior, a derivation that is not a process in time or space. 3. Each derived being is established in its own reality by turning back toward its superior in a movement of contemplative desire, which is implicit in the original creative impulse of outgoing that it receives from its superior; thus the Neoplatonic universe is characterized by a double movement of outgoing and return. 4. Each level of being is an image or expression on a lower level of the one above it. The rela- tion of archetype and image runs through all Neoplatonic schemes. 5. Degrees of being are also degrees of unity; as one goes down the scale of being there is greater multiplicity, more separateness, and increasing limitation—until the atomic individuali- zation of the spatiotemporal world is reached. 6. The highest level of being, and through it all of what in any sense exists, derives from the ul- timate principle, which is absolutely free from determinations and limitations and utterly tran- scends any conceivable reality, so that it may be said to be “beyond being.” Because it has no limitations, it has no division, attributes, or qualifications; it cannot really be named, or even properly described as being, but may be called “the One” to designate its complete simplicity. It may also be called “the Good” as the source of all perfections and the ultimate goal of return, for the impulse of outgoing and return that constitutes the hierarchy of derived reality comes from and leads back to the Good. 7. Since this supreme principle is absolutely simple and undetermined (or devoid of specific traits), man's knowledge of it must be radically different from any other kind of knowledge. It is not an object (a separate, determined, limited thing) and no predicates can be applied to it; hence it can be known only if it raises the mind to an immediate union with itself, which cannot be imagined or described.
