We may imagine, for the purpose of illustration, this man saying: Here is another being who appears to be like myself. He is capable of suffering pain, as I am. He does not like pain any better than I do. Therefore, I have no right to make him suffer that which I do not wish to suffer myself. This other man is capable of pleasure. He desires certain things, similar things to those which I desire. If I do not wish him to take these things away from me, I have no right to take them away from him.

I do not mean that this was thought out in this clear way, but that, when there was the first dim perception of this other self, with similar feelings, similar possibilities, similar pleasures, similar pains, then there became a conscience, because there was a consciousness of this similarity of nature. Morality, then, is born as a social fact.

To go a little deeper, and in order to trace the natural and historical growth of the moral ideal, let me say that morality in its deepest and truest sense is born of the fact of sex, because it is right in there that we find the root and the germ of permanent social relations. And I wish you to note another very significant fact. You hear people talking about selfishness and unselfishness, as though they were direct contraries, mutually exclusive of each other, as though, in order to make a selfish man unselfish, you must completely reverse his nature, so to speak. I do not think this is true at all. Unselfishness naturally and necessarily springs out of selfishness, and, in the deepest sense of the word, is not at all contradictory to that.

For example: A man falls in love with a woman. This, on one side of it, is as selfish as anything you can possibly conceive. But do you not see by what subtle and divine chemistry the selfishness is straightway transformed, lifted up, glorified, and becomes unselfishness? The very love that he professes for her makes it necessary for his own happiness that she should be happy, so that, in seeking for his own selfish gratification, he is devoting himself unselfishly to the happiness of somebody else.

And, when a child is born, do you not see, again, how the two selfishnesses, the father's and the mother's, selfishly, if you please, brooding over and loving the child, at once go out of themselves, consecrating time and care and thought and love, and even health or life itself, if need be, for the welfare of the child?

Right in there, then, out of this fact of sex and in the becoming of the family, are born love and sympathy, and tenderness and mutual care, all those things which are the highest and finest constituent elements of the noblest developments of the moral nature of men.

Imagination plays a large part in the development of morality; for you must be able to put yourself imaginatively in the place of another before you can feel for that other, and in that way recognize the rights of that other and be ready to grant these rights to that other. So we find that morality at first is a narrow thing: it is confined perhaps to the little family, the father, the mother, the child, bound together by these ties of kinship, of love, of sympathy, devoting themselves to each other; but they may look upon some other family as their natural enemies, and feel no necessity whatever to apply these same principles of love and tenderness and care beyond the limits of their own little circle.

So you find, as you study the growth of the moral nature of man, that it is confined at first to the family, then to the patriarchal family, then the tribe; but the fiction of kinship is still kept up, and, while the member of the primeval tribe feels he has no right to rob or murder within the limits of his tribe, he has no compunction whatever about robbing or murdering or injuring the members of some other tribe. So the moral principle in its practical working is limited to the range of the sympathy of the tribe, which does not go beyond the tribal limits. We see how that principle works still in the world, from the beginning clear up to the highest reaches which we have as yet attained.

Take the next step, and find a city like ancient Athens. Still, perhaps, the fiction of kinship is maintained. All the citizens of Athens are regarded as members of the same great tribe or family. But even in the time of Plato, whom we are accustomed to look upon as one of the great teachers of the world, there was no thought of any moral obligation to anybody who lived in Sparta, lived in any other city of Greece, and less was there any thought of moral obligation as touching or taking in the outside barbarian. So when the city grew into a nation, and we came to a point where the world substantially stands to-day, do you not see that practically the same principle holds, that, while we recognize in some abstract sort of fashion that we ought to do justice and be kind to people beyond our own limits, yet all our political economy, all our national ideas, are accustomed to emphasize the fact that we must be just and righteous to our own people, but that aggression, injustice of almost any kind, is venial in our treatment of the inhabitants of another country? And it may even flame up into the fire of a wordy patriotism in certain conditions; and love of country may mean hatred and injustice towards the inhabitants of another country, or particularly towards the people of another race.

Let me give you a practical illustration of it. What are the relations in which we stand to-day towards Spain? I have unbounded admiration for the patience, on the whole, for the justice, the sense of right, which characterize the American people. I doubt if there is another nation on the face of the earth to-day that would have gone through the last two or three years of our experience, and maintained such an attitude of impartiality, of faithfulness, of justice, of right. And yet, if we examine ourselves, we shall find that it is immensely difficult for us to put ourselves in the place of a Spaniard, to look at the Cuban question from his point of view, to try to be fair, to be just to him. It is immensely difficult, I say, for us to look at one of these international questions from the point of view of another race, cherishing other religious and social ideas, having another style of government.
