Thus the mold will be hardened. So new truths, when they come, can but break it. Then men will feel distraught and disillusioned, and civilizations will fall.
Thus each cycle will run. So long as men intertwine falsehoods with every seer's visions, both perish, and every civilization that is built on them must perish too.
EIGHTEEN
If men can ever learn to accept all their truths as not final, and if they can ever learn to build on something better than dogma, they may not be found saying, discouragedly, every once in so often, that every civilization carries in it the seeds of decay. It will carry such seeds with great certainty, though, when they're put there, by the very race, too, that will later deplore the results. Why shouldn't creeds totter when they are jerry-built creeds?
On stars where creeds come late in the life of a race; where they spring from the riper, not cruder, reactions of spirit; where they grow out of nobly developed psychic powers that have put their possessors in tune with cosmic music; and where no cheap hallucinations discredit their truths; they perhaps run a finer, more beautiful course than the simians', and open the eyes of the soul to far loftier visions.
NINETEEN
It has always been a serious matter for men when a civilization decayed. But it may at some future day prove far more serious still. Our hold on the planet is not absolute. Our descendants may lose it.
Germs may do them out of it. A chestnut fungus springs up, defies us, and kills all our chestnuts. The boll weevil very nearly baffles us. The fly seems unconquerable. Only a strong civilization, when such foes are about, can preserve us. And our present efforts to cope with such beings are fumbling and slow.
