When we talk of space to-day, we are all thinking more or less in the same style, just as we are all using the same languages and word-signs, whether we are considering mathematical space or physical space or the space of painting or that of actuality, although all philosophizing that insists (as it must) upon putting an _identity_ of understanding in the place of such kinship of significance-feeling must remain somewhat questionable. But no Hellene or Egyptian or Chinaman could re-experience any part of those feelings of ours, and no artwork or thought-system could possibly convey to him unequivocally what “space” means for us. Again, the prime conceptions originated in the quite differently constituted soul of the Greek, like ἀρχή, ὕλη, μορφἠ, comprise the whole content of his world. But this world is differently constituted from ours. It is, for us, alien and remote. We may take these words of Greek and translate them by words of our own like “origin,” “matter” and “form,” but it is mere imitation, a feeble effort to penetrate into a world of feeling in which the finest and deepest elements, in spite of all we can do, remain dumb; it is as though one tried to set the Parthenon sculptures for a string quartet, or cast Voltaire’s God in bronze. The master-traits of thought, life and world-consciousness are as manifold and different as the features of individual men; in those respects as in others there are distinctions of “races” and “peoples,” and men are as unconscious of these distinctions as they are ignorant of whether “red” and “yellow” do or do not mean the same for others as for themselves. It is particularly the common symbolic of language that nourishes the illusion of a homogeneous constitution of human inner-life and an identical world-form; in this respect the great thinkers of one and another Culture resemble the colour-blind in that each is unaware of his own condition and smiles at the errors of the rest.
