In the terrestial creation, in the realm of nature, no sooner did the behest go forth, “Let there be light,” than the accomplishment forthwith followed. Scarcely was this light and life-creating word spoken, than it was succeeded, spontaneously and immediately, without let or hinderance, by the second word of the joyful conclusion: “And there was light.” Quite otherwise, however, is it in the life and in the world of free-created man, in the progression of his intellectual development, in the history of his mind [_geist_], in his now advancing, now retrograding thought and knowledge. Here, indeed, the first call to light and divine truth does not pass over even man’s stubborn and taciturn heart altogether unheeded and unanswered, and without eliciting some faint response. But lasting is the struggle between light and darkness, between knowledge and ignorance, between faith and infidelity. Ever wavering from side to side, and fluctuating from one extreme to another, the victory long remains undecided. And centuries often, nay, thousands of years, pass away ere with perfect truth that word of fulfillment and completion can be uttered, and we can go on, undoubtedly, to say, “And there was light.” Even when the true end is pursued along the direct road, the right track is often lost amid the endless strife and controversy of men, while a long train of useless discussion raises so thick a cloud of dust as shuts it entirely out of sight, and so a new route has to be sought and opened from quite an opposite quarter.
