ture of colouredness in general.[25]

Both in the case of colour and in that of space there is to be found
the distinction between universal and individual, and therefore also
that between conception and perception. It may be objected that after
all, as Kant points out, there is only one space, whereas there are
many individual colours. But the assertion that there is only one
space simply means that all individual bodies in space are related
spatially. This will be admitted, if the attempt be made to think of
two bodies as in different spaces and therefore as not related
spatially. Moreover, there is a parallel in the case of colour, since
individual coloured bodies are related by way of colour, e. g. as
brighter and duller; and though such a relation is different from a
relation of bodies in respect of space, the difference is due to the
special nature of the universals conceived, and does not imply a
difference between space and colour in respect of perception and
conception. In any case, space as a whole is not object of perception,
which it must be if Kant is to show that space, as being one, is
perceived; for space in this context must mean the totality of
individual spaces.

Kant's second argument is stated as follows: "Space is represented as
an infinite _given_ magnitude. Now every conception must indeed be
considered as a representation which is contained in an infinite
number of different possible representations (as their common mark),
and which therefore contains these _under itself_, but no conception
can, as such, be thought of as though it contained _in itself_ an
infinite number of representations. Nevertheless, space is so
conceived, for all parts of space _ad infinitum_ exist simultaneously.
Consequently the original representation of space is an _a priori
perception_ and not a _conception_." In other words, while a
conception implies an infinity of individuals which come under it, the
elements which constitute the conception itself (e. g. that of
triangularity or redness) are not infinite; but the elements which go
to constitute space are infinite, and therefore space is not a
conception but a perception.

Though, however, space in the sense of the infinity of spaces may be
said to contain an infinite number of spaces if it be meant that it
_is_ these infinite spaces, it does not follow, nor is it true, that
space i
