1.a. One is not many, and therefore has no parts, and therefore is not
a whole, which is a sum of parts, and therefore has neither beginning,
middle, nor end, and is therefore unlimited, and therefore formless,
being neither round nor straight, for neither round nor straight can be
defined without assuming that they have parts; and therefore is not in
place, whether in another which would encircle and touch the one at
many points; or in itself, because that which is self-containing is also
contained, and therefore not one but two. This being premised, let us
consider whether one is capable either of motion or rest. For motion is
either change of substance, or motion on an axis, or from one place to
another. But the one is incapable of change of substance, which implies
that it ceases to be itself, or of motion on an axis, because there
would be parts around the axis; and any other motion involves change of
place. But existence in place has been already shown to be impossible;
and yet more impossible is coming into being in place, which implies
partial existence in two places at once, or entire existence neither
within nor without the same; and how can this be? And more impossible
still is the coming into being either as a whole or parts of that which
is neither a whole nor parts. The one, then, is incapable of motion.
But neither can the one be in anything, and therefore not in the same,
whether itself or some other, and is therefore incapable of rest.
Neither is one the same with itself or any other, or other than itself
or any other. For if other than itself, then other than one, and
therefore not one; and, if the same with other, it would be other, and
other than one. Neither can one while remaining one be other than other;
for other, and not one, is the other than other. But if not other by
virtue of being one, not by virtue of itself; and if not by virtue
of itself, not itself other, and if not itself other, not other than
anything. Neither will one be the same with itself. For the nature of
the same is not that of the one, but a thing which becomes the same with
anything does not become one; for example, that which becomes the same
with the many becomes many and not one. And therefore if the one is the
same with itself, the one is not one with itself; and therefore one and
not one. And therefore one is neither other than other, nor the same
with itself. Neither will the one be like or unlike itself or other;
for likeness is sameness of affections, and the one and the same are
different. And one having any affection which is other than being one
would be more than one. The one, then, cannot have the same affection
with and therefore cannot be like itself or other; nor can the one
have any other affection than its own, that is, be unlike itself or any
other, for this would imply that it was more than one. The one, then,
is neither like nor unlike itself or other. This being the case, neither
