The churches have always drawn their morality from the Bible, and have always tried to fit it in with the immoral codes made by kings, soldiers, landlords, money-lenders, and other immoral persons.
The Church has often pleaded for "charity" to the poor, but has never come to the rescue of the "Bottom Dog"; because the churches have never understood morality nor human nature.
It is science, and not the revelation of God, nor the teaching of priests, that has enabled us to begin to understand human nature, and has made it possible to build up a systematic code of true morality.
As to what morality is, I claim it is the rule of social conduct: the measure of right conduct between man and man; and I shall build up my whole case upon the simple moral rule that "every act is immoral which needlessly injures any fellow-creature." This rule is only an old truth in a new form. It is, indeed, just a modern reading of the "Golden Rule." It is not the rule itself, but the use I shall put it to, that is likely to flutter certain moral dovecotes. As to the rule, the teachings of most great moralists, of all times and nations, go to prove it. As, for instance:
Lao Tze, a Chinese moralist, before Confucius, said: "The good I would meet with goodness, the not-good I would also meet with goodness."
Confucius, Chinese moralist, said: "What you do not want done to yourself, do not do to others."
He also said: "Benevolence is to be in one's most inward heart in sympathy with all things; to love all men; and to allow no selfish thoughts."
The same kind of teaching is found in the Buddhist books, and in the rock edicts of King Asoka. Here is a Buddhist precept, which has a special interest as touching the origin of morals.
"Since even animals can live together in mutual reverence, confidence, and courtesy, much more should you, O brethren, so let your light shine forth that you may be seen to dwell in like manner together."
The Hebrew moralists often sounded the same note. In Leviticus we find: "Thou shalt love thy neighbour as thyself."
