"An unreflective mood, he said, is general among both cultured and uncultured, characterised by indifference to everything beyond material interests and the superficial aspects of things." . . . "But in both cultured and un- cultured there occur lucid intervals. Some, at least, either fill the vacuum by stereotyped answers, or become conscious of unanswered questions of transcendent moment. By those who know much, more than by those who know little, is there felt the need for explanation. Whence this process, inconceivable however symbolised, by which alike the monad and the man build themselves up into their respective structures ? What must we say of the life, minute, multi- tudinous, degraded, which, covering the ocean-floor, occupies by far the larger part of the Earth's area; and which yet, growing and decaying in utter darkness, presents hundreds of species of a single type ? Or, when we think of the myriads of years of the Earth's past, during which have arisen and passed away low forms of creatures, small and great, which, murdering and being murdered, have gradually evolved, how shall we answer the question—To what end ? Ascending to wider problems, in which way are we to interpret the life- lessness of the greater celestial masses—the giant planets and the Sun; in proportion to which the habitable planets are mere nothings ? If we pass from these relatively near bodies to the thirty millions of remote suns and solar systems, where shall we find a reason for all this apparently unconscious ex- istence, infinite in amount compared with the existence which is conscious—a waste Universe as it seems ? Then behind these mysteries lies the all-embracing mystery—whence this universal transformation which has gone on unceasingly throughout a past eternity and will go on unceasingly through- out a future eternity ? And along with this rises the paralys- ing thought—what if, of all that is thus incomprehensible to us, there exists no comprehension anywhere ? No wonder that men take refuge in authoritative dogma! " " So is it, too, with our own natures. No less inscrutable is this complex consciousness which has slowly evolved out
