There are some who would deter us from inquiring into anything beyond the range of sensible experience, and especially from any inquiry into the future existence of the soul, which they denounce as utterly unpractical, and compare with obsolete and fruitless inquiries into the state of the soul before birth. We have already challenged the exclusive claim of the five bodily senses to be the final sources of knowledge; and we may surely add that it is at least as practical to inquire into the destiny as it is to inquire into the origin of man. If the belief in God and in a Future State is true, it will prevail. The cloud will pass away and the sun will shine out again. But in the meantime society may have "a bad quarter of an hour." Without exaggerating the influence of the belief in Future Reward and Punishment, or of any form of it, on the actions of ordinary men, we may safely say that the sense of responsibility to a higher power, and of the constant presence of an all-seeing Judge, has exercised an influence, the removal of which would be greatly felt. Materialism has in fact already begun to show its effects on human conduct and on society. They may perhaps be more visible in communities where social conduct depends greatly on individual conviction and motive, than in communities which are more ruled by tradition and bound together by strong class organizations; though the decay of morality will perhaps be ultimately more complete and disastrous in the latter than in the former. God and future retribution being out of the question, it is difficult to see what can restrain the selfishness of an ordinary man, and induce him, in the absence of actual coercion, to sacrifice his personal desires to the public good. The service of Humanity is the sentiment of a refined mind conversant with history; within no calculable time is it likely to overrule the passions and direct the conduct of the mass. And after all, without God or spirit, what is "Humanity"? One school of science reckons a hundred and fifty different species of man. What is the bond of unity between all these species and wherein consists the obligation to mutual love and help? A zealous servant of science told Agassiz that the age of real civilization would have begun when you could go out and shoot a man for scientific purposes. _Apparent dirae facies_. We begin to perceive, looming through the mist, the lineaments of an epoch of selfishness compressed by a government of force. PROPOSED SUBSTITUTES FOR RELIGION There appears to be a connection between the proposed substitutes for religion and the special training of their several authors. Historians tender us the worship of Humanity, professors of physical science tender us Cosmic Emotion. Theism might almost retort the apologue of the specter of the Brocken.
