. And so with 'cause' and 'one' and all such terms. For
this reason, too, 'to be one' means 'to be indivisible, being
essentially one means a "this" and capable of being isolated either in
place, or in form or thought'; or perhaps 'to be whole and
indivisible'; but it means especially 'to be the first measure of a
kind', and most strictly of quantity; for it is from this that it
has been extended to the other categories. For measure is that by
which quantity is known; and quantity qua quantity is known either
by a 'one' or by a number, and all number is known by a 'one'.
Therefore all quantity qua quantity is known by the one, and that by
which quantities are primarily known is the one itself; and so the one
is the starting-point of number qua number. And hence in the other
classes too 'measure' means that by which each is first known, and the
measure of each is a unit-in length, in breadth, in depth, in
weight, in speed. (The words 'weight' and 'speed' are common to both
contraries; for each of them has two meanings-'weight' means both that
which has any amount of gravity and that which has an excess of
gravity, and 'speed' both that which has any amount of movement and
that which has an excess of movement; for even the slow has a
certain speed and the comparatively light a certain weight.)
In all these, then, the measure and starting-point is something
one and indivisible, since even in lines we treat as indivisible the
line a foot long
