this element itself is either not yet or no longer. But precisely so, in the conceptual time of our real world, the Present means any section of the time-stream in so far as, with reference to anybody's consciousness, it is viewed as having relation to this unity of consciousness, and as in a single whole of meaning with this unity. Usually by “our time,” or “the real time in which we now live,” we mean no very long period of the conceived time-stream of the real world. But we never mean the indivisible now of an ideal mathematical time, because, in such an indivisible time-instant, nothing could happen, or endure, or genuinely exist. But within the present, if conceived as a section of the time-stream, there are internal differences of present, past, and future.
For, in a similar fashion, as the actual or supposed length of the “specious present” of our perceptual time is something arbitrary, determined by our peculiar human type of consciousness, so the length of the portion of conceptual time which we call the present, in the first sense of that term, namely, in the sense in which we speak of the “present age,” is an arbitrary length, determined in this case, however, by our more freely chosen interest in some unity which gives relative wholeness and meaning to this present. If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years. On the other hand, within the unity of this
