concerning time they do not even occur, and in fact one cannot see any relation which could connect them with what is said there. But only this spatial form enables time and space to be brought into functional interdependence as magnitudes _of the same_ order, as four-dimensional vector analysis[110] conspicuously shows. As early as 1813 Lagrange frankly described mechanics as a four-dimensional geometry, and even Newton’s cautious conception of “tempus absolutum sive duratio” is not exempt from this _intellectually inevitable_ transformation of the living into mere extension. In the older philosophy I have found one, and only one, profound and reverent presentation of Time; it is in Augustine—“If no one questions me, I know: if I would explain to a questioner, I know not.”[111] When philosophers of the present-day West “hedge”—as they all do—by saying that things _are_ in time as in space and that “outside” them nothing is “conceivable,” they are merely putting another kind of space (Räumlichkeit) beside the ordinary one, just as one might, if one chose, call hope and electricity the two forces of the universe. It ought not, surely, to have escaped Kant when he spoke of the “two forms” of perception, that whereas it is easy enough to come to a scientific understanding about space (though not to “explain” it, in the ordinary sense of the word, for that is beyond human powers), treatment of time on the same lines breaks down utterly. The reader of the “Critique of Pure Reason” and the “Prolegomena” will observe that Kant gives a well- considered proof for the connexion of space and geometry but carefully avoids doing the same for time and arithmetic. There he did not go beyond enunciation, and constant reassertion of analogy between the two conceptions lured him over a gap that would have been fatal to his system. _Vis-à-vis_ the Where and the How, the When forms a world of its own as distinct as is metaphysics from physics. Space, object, number, notion, causality are so intimately akin that it is impossible—as countless mistaken systems prove—to treat the one independently of the other. Mechanics is a copy of the logic of its day and vice versa. The picture of thought as psychology builds it up and the picture of the space-world as contemporary physics describes it are reflections of one another. Conceptions and things, reasons and causes, conclusions and processes coincide so nicely, as received by the consciousness, that the abstract thinker himself has again and again succumbed to the temptation of setting forth the thought-“process” graphically and schematically— witness Aristotle’s and Kant’s tabulated categories. “Where there is no scheme, there is no philosophy” is the objection of principle— unacknowledged though it may be—that all professional philosophers have against the “intuitives,” to whom inwardly they feel themselves far superior. That is why Kant crossly describes the Platonic style of
