In primitive Buddhism, in primitive Christianity, in the writings of some of the Mussulman teachers, in the early movements of the Reform, and especially in the ethical and philosophical movements of the last century and of our own times, the total abandonment of the idea of revenge, or of “due reward” — of good for good and evil for evil — is affirmed more and more vigorously. The higher conception of “no revenge for wrongs”, and of freely giving more than one expects to receive from his neighbours, is proclaimed as being the real principle of morality — a principle superior to mere equivalence, equity, or justice, and more conducive to happiness. And man is appealed to to be guided in his acts, not merely by love, which is always personal, or at the best tribal, but by the perception of his oneness with each human being. In the practice of mutual aid, which we can retrace to the earliest beginnings of evolution, we thus find the positive and undoubted origin of our ethical conceptions; and we can affirm that in the ethical progress of man, mutual support — not mutual struggle — has had the leading part. In its wide extension, even at the present time, we also see the best guarantee of a still loftier evolution of our race.
