Plotinos: Complete Works, v. 3 In Chronological Order,...

1. We have thus declared our views about (intelligible) Being, and shown how they agree with the doctrines of Plato. Now we have to study the "other nature" (the Being of the sense-world); and we shall have to consider whether it be proper to establish here the same genera as for the intelligible world, or to posit a greater number, by adding some to those already recognized; or whether the genera differ in each being entirely, or only partially, some remaining identical, while others differ. If any of them be identical in both beings, that can be understood only by analogy;343 that is what will become evident when each of these beings are fully understood.
