body different from itself, arguing from this
that there is no space beyond the world, and
> world as a whole is not in space, but only its
arts. 3
In the same way the homogeneous parts

lly in space ; they are not actually so until
d from the whole. 4 It is the same with Time,

subject. He remarks expressly, however, that

ing Time as a mere form of our perception, he
it rather as something pertaining to motion,

defines the meaning of coexistence in space, of contact,
of intermediate space, of succession, of continuity, &c.'
He distinguishes the different relations in which the
unity of motion can be spoken of, 2 finding the absolute
unity of motion in continuous or unbroken movement
that is, in such as belongs to one and the same object
in the same relation at one and the same time. 3 He
asks what constitutes uniformity of motion and its

in what cases two movements, or movement
and repose, may be said to be opposed to each other
how far the natural or unnatural character of a movement
has to be considered in either instance. 5 After
proving further that all continuous magnitudes are
divisible ad infinitum? that time and space in this
respect correspond, and that in reality it is only with
