The first and veritable Number is therefore the source and
principle[21] of hypostatic existence for beings. That is the reason
that even here below, the classified both discrete and continuous
quantity[38] and, with a different number, it is some other thing that
is begotten, or nothing more can be begotten. Such are the primary
Numbers, so far as they can be numbered. The numbers that subsist in
other things play two parts. So far as they proceed from the First,
they can be numbered; so far as they are below them, they measure other
things, they serve to enumerate both numbers and things which can be
enumerated. How indeed could you even say "ten" without the aid of
numbers within yourself?
