Time and Space.
We now come to natural philosophy. Here again Herr Duehring takes it upon himself to be dissatisfied with his predecessors. He says "Natural philosophy sank so low that it became barren dregs of poetry and had fallen into the degraded rubbish of the sham philosophy of a Schelling and the like, grubbing in priest-craft and mystifying the public." Disgust has rid us of these deformities, but up to the present it has been succeeded by instability, and "what is of concern to the public at large is that the disappearance of a particularly great charlatan merely gives an opportunity to a smaller but more expert successor who repeats the production in another form." Naturalists have little desire for "a flight into the kingdom of the universe-comprehending ideas," and therefore indulge too freely in speculations which "go to pieces." Thus complete salvation must be found, and, fortunately, Herr Duehring is at hand.
In order to comprehend aright the following conclusions respecting the unfolding of the universe in time and its limitation in space, we must again turn our attention to certain portions of the "scheme of the universe."
Eternity is ascribed to existence, in agreement with Hegel, what Hegel calls "tiresome (schlecht) eternity," and this eternity is now investigated. "The plainest form of an incontrovertible idea of eternity is the piling up of numbers unlimitedly in arithmetical progression. Just as we can give a complete unity to each number without the possibility of repetition, so at every stage of its being it progresses still further and eternity consists in the unlimited manifestation of this condition. This sufficiently conceived eternity has but one single beginning with one single direction. Although it is not material to our concept to imagine a direction opposite to that in which the progression piles up, this notion of a backward moving eternity is only a hasty picture drawn by the imagination. Since it must necessarily run in a contrary direction, it would have behind it in each instance an endless succession of numbers. But this would be inadmissible as constituting the contradiction of a calculated infinity of numbers, and so it seems absurd to imagine a second direction of eternity."
The first conclusion to be drawn from this conception of eternity is that the chain of cause and effect in the universe must once have had a beginning: an endless number of causes which have followed one another endlessly is therefore unthinkable, "because innumerability is thus considered as enumerated," therefore a final cause is proved.
