If history did not enable us to trace this derivation, the ever-present practical standard for faith would sufficiently indicate it; for no one would accept as divine a revelation which he felt to be immoral or found to be pernicious. And yet such a deviation into the maleficent is always possible when a code is uprooted from its rational soil and transplanted into a realm of imagination, where it is subject to all sorts of arbitrary distortions. If the sexual instinct should attach us (as in its extensions and dislocations it sometimes does) to beings incapable of satisfying it or of uniting with us in propagating the race, we should, of course, study to correct that aberration so that our joys and desires might march in step with the possible progress of the world. In the same way, if the gregarious instinct should bring us into the imagined presence of companions that really did not exist, or on whose attitude and co-operation our successes in no way depended, we should try to lead back our sense of fellowship to its natural foundations and possible sanctions. Society exists so far as does analogous existence and community of ends. We may, in refining the social instinct, find some fellowship in the clouds and in the stars, for these, though remote, are companions of our career. By poetic analogy we may include in the social world whatever helps or thwarts our development, and is auxiliary to the energies of the soul, even if that object be inanimate. Whatever spirit in the past or future, or in the remotest regions of the sky, shares our love and pursuit, say of mathematics or of music, or of any ideal object, becomes, if we can somehow divine his existence, a partner in our joys and sorrows, and a welcome friend.
