On the Fourfold Root of the Principle of Sufficient Reason, and On the Will in Nature: Two Essays (revised edition)
Schopenhauer · en
From the foregoing exposition it follows, that the application of the
causal law to anything but _changes_ in the material, empirically given
world, is an abuse of it. For instance, it is a misapplication to make
use of it with reference to physical forces, without which no changes
could take place; or to Matter, _on_ which they take place; or to the
world, to which we must in that case attribute an absolutely objective
existence independently of our intellect; indeed in many other cases
besides. I refer the reader to what I have said on this subject in my
chief work.[109] Such misapplications always arise, partly, through
our taking the conception of cause, like many other metaphysical and
ethical conceptions, in far _too wide_ a sense; partly, through our
forgetting that the causal law is certainly a presupposition which
we bring with us into the world, by which the perception of things
outside us becomes possible; but that, just on that account, we are
not authorized in extending beyond the range and independently of our
cognitive faculty a principle, which has its origin in the equipment of
that faculty, nor in assuming it to hold good as the everlasting order
of the universe and of all that exists.

§ 25. _The Time in which a Change takes place._
As the Principle of Sufficient Reason of Becoming is exclusively
applicable to _changes_, we must not omit to mention here, that the
ancient philosophers had already raised the question as to the time in
which a change takes place, there being no possibility of it taking
place during the existence of the preceding state nor after the new one
has supervened. Yet, if we assign a special time to it between both
states, a body would, during this time, be neither in the first nor in
the second state: a dying man, for instance, would be neither alive nor
dead; a body neither at rest nor in movement: which would be absurd.
The scruples and sophistic subtleties which this question has evoked,
may be found collected together in Sextus Empiricus "Adv. Mathem."
lib. ix. 267-271, and "Hypat." iii. c. 14; the subject is likewise
dealt with by Gellius, l. vi. c. 13--Plato[110] had disposed somewhat
cavalierly of this knotty point, by maintaining that changes take place
_suddenly_ and occupy _no time at all_; they occur, he says, in the
ἐξαίφνης (_in repentino_), which he calls an ἄτοπος φύσις, ἐν χρόνῳ
οὐδὲν οὖσα; a strange, timeless existence (which nevertheless comes
within Time).
