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.
