Every quantity is intellectually conceivable as infinitely
divisible.

[Amid the vastness of the things among which we live, the existence
of nothingness holds the first place; its function extends over all
things that have no existence, and its essence, as regards time,
lies precisely between the past and the future, and has nothing in
the present. This nothingness has the part equal to the whole, and
the whole to the part, the divisible to the indivisible; and the
product of the sum is the same whether we divide or multiply, and in
addition as in subtraction; as is proved by arithmeticians by their
tenth figure which represents zero; and its power has not extension
among the things of Nature.]

[What is called Nothingness is to be found only in time and in
speech. In time it stands between the past and future and has no
existence in the present; and thus in speech it is one of the things
of which we say: They are not, or they are impossible.]

With regard to time, nothingness lies between the past and the
future, and has nothing to do with the present, and as to its nature
it is to be classed among things impossible: hence, from what has
been said, it has no existence; because where there is nothing there
would necessarily be a vacuum.
