I have quoted more fully than had been my intention simply to show the egotistic ignorance of the Christian's claim to possess a religion or a Bible which differs, in any material regard, from several others which are older, and to indicate that moral ideas, precepts, and practices are the property of no special people, but are the inevitable result of continued life itself, and the evolution of civilizations however different in outward form and expression. They are the necessary results of human companionship and necessities, and not the fruits of any religion or the "revelation" from on high to any people. As William Kingdon Clifford, F. R. S., in his work on the "Scientific Basis of Morals," very justly says: "There is more than one moral sense, and what I feel to be right another man may feel to be wrong. "In just the same way our question about the best conscience will resolve itself into a question about the purpose or function of the conscience--why we have got it, and what it is good for. "Now to my mind the simplest and clearest and most profound philosophy that was ever written upon this subject is to be found in the 2d and 3d chapters of Mr. Darwin's 'Descent of Man.' In these chapters it appears that just as most physical characteristics of organisms have been evolved and preserved because they were useful to the individual in the struggle for existence against other individuals and other species, so this particular feeling has been evolved and preserved because it is useful to the tribe or community in the struggle for existence against other tribes, and against the environment as a whole. The function of conscience is the preservation of the tribe as a tribe. And we shall rightly train our consciences if we learn to approve these actions which tend to the advantage of the community. "The virtue of purity, for example, attains in this way a fairly exact definition: purity in a man is that course of conduct which makes him to be a good husband and father, in a woman that which makes her to be a good wife and mother, or which helps other people so to prepare and keep themselves. It is easy to see how many false ideas and pernicious precepts are swept away by even so simple a definition as that."
