Time is continued and perpetual.
_Demonstration._—For, if it is neither continued nor eternal, it will
have a certain beginning. Let, therefore, A B be time, and let its
beginning be A. But if A is time, it is divisible, and we shall not yet
have the beginning of time, but there will be another beginning of the
beginning. But, if A is a moment or _the now_, it will be indivisible,
and the boundary of another time: for _the now_ is not only a beginning,
but an end. There will therefore be time before A. Again: if B is the
boundary of time, if B is time, it may be divided to infinity, and into
the many boundaries which it contains. But if B is _the now_, the same
will also be a beginning: for _the now_ is not only a boundary, but a
beginning[60].
