degree or magnitude by which it can fill the same
time, i. e. the internal sense, in respect of the same representation
of an object, more or less, until it vanishes into nothing ( = 0 =
_negatio_). There is, therefore, a relation and connexion between
reality and negation, or rather a transition from the former to the
latter, which makes every reality representable as a _quantum_; and
the schema of a reality, as the quantity of something so far as it
fills time, is just this continuous and uniform generation of the
reality in time, as we descend in time from the sensation which has a
certain degree, down to the vanishing thereof, or gradually ascend
from negation to the magnitude thereof."[16]

[15] It is difficult to see how Kant could meet the criticism
that here, contrary to his intention, he is treating physical
objects as things in themselves. Cf. p. 265.

This passage, if it be taken in connexion with the account of the
anticipations of perception,[17] seems to have the following meaning:
'In thinking of something as a reality, we think of it as that which
corresponds to, i. e. produces, a sensation, and therefore as
something which, like the sensation, is in time; and just as every
sensation, which, as such, occupies time, has a certain degree of
intensity, so has the reality which produces it. Now to produce for
ourselves an instance of a reality in this sense, we must add units of
reality till a reality of the required degree is produced, and the
thought of this method on our part of constructing an individual
reality is the schema of reality.' But if this represents Kant's
meaning, the schema of reality relates only to our process of
apprehension, and therefore is not a conception which relates to
objects and is more concrete than the corresponding category in
respect of time. Moreover, it is matter for surprise that in the case
of this category Kant should have thought schematism necessary, for
time is actually included in his own statement of the category.

[17] B. 207-18, M. 125-32.

The account of the schemata of the remaining categories need not be
considered. It merely _asserts_ that certain conceptions relating
to objects and involving the thought of time are the schemata
corresponding to the remaining categories, without any attempt to
connect them with the nature of a schema. Thus, the schema of
substance is asserted to be the _permanence_ of the r
