For when any new and wide-reaching truth comes into the world--and if it is new, it must be paradoxical--an obstinate stand will be made against it as long as possible; nay, people will continue to deny it even after they slacken their opposition and are almost convinced of its truth. Meanwhile it goes on quietly working its way, and, like an acid, undermining everything around it. From time to time a crash is heard; the old error comes tottering to the ground, and suddenly the new fabric of thought stands revealed, as though it were a monument just uncovered. Everyone recognizes and admires it. To be sure, this all comes to pass for the most part very slowly. As a rule, people discover a man to be worth listening to only after he is gone; their _hear, hear_, resounds when the orator has left the platform. Works of the ordinary type meet with a better fate. Arising as they do in the course of, and in connection with, the general advance in contemporary culture, they are in close alliance with the spirit of their age--in other words, just those opinions which happen to be prevalent at the time. They aim at suiting the needs of the moment. If they have any merit, it is soon recognized; and they gain currency as books which reflect the latest ideas. Justice, nay, more than justice, is done to them. They afford little scope for envy; since, as was said above, a man will praise a thing only so far as he hopes to be able to imitate it himself. But those rare works which are destined to become the property of all mankind and to live for centuries, are, at their origin, too far in advance of the point at which culture happens to stand, and on that very account foreign to it and the spirit of their own time. They neither belong to it nor are they in any connection with it, and hence they excite no interest in those who are dominated by it. They belong to another, a higher stage of culture, and a time that is still far off. Their course is related to that of ordinary works as the orbit of Uranus to the orbit of Mercury. For the moment they get no justice done to them. People are at a loss how to treat them; so they leave them alone, and go their own snail's pace for themselves. Does the worm see the eagle as it soars aloft? Of the number of books written in any language about one in 100,000 forms a part of its real and permanent literature. What a fate this one book has to endure before it outstrips those 100,000 and gains its due place of honor! Such a book is the work of an extraordinary and eminent mind, and therefore it is specifically different from the others; a fact which sooner or later becomes manifest.
