Plotinos: Complete Works, v. 2 In Chronological Order,...

1. (Aristotle) spoke of (things) existing "potentially," and "actually"; and actuality is spoken of as a "being." We shall, however, have to examine this potential and actual existence; and whether this actual existence be the same as actuality, and whether this potential existence be identical with potentiality; also, whether these conceptions differ so that what exists actually be not necessarily actuality. It is evident that among sense-objects there exist things potentially. Are there also such among the intelligibles? This then is the problem: whether the intelligibles exist only actually; and on the hypothesis of the existence among intelligibles of something existing potentially, whether, because of its eternity, this always remains there in potentiality; and, because it is outside of time, never arrives to actuality.
