Another bestial tendency is the lust of the male for the female apart from love, duty, and loyalty; this again has been encouraged by religion, as witness the polygamy and concubinage of the Hebrews--as in Abraham, David, and Solomon, not to mention the precepts of the Mosaic laws--the bands of male and female prostitutes in connection with Pagan temples, and the curious outbursts of sexual passion in connection with religious revivals and missions.

Another bestial tendency is greed, the strongest grabbing all he can and trampling down the weak, in the mad struggle for wealth; how and when has religion modified this tendency, sanctified as it is in our present civilisation?
All these bestial tendencies will be eradicated only by the recognition of human duty, of the social bond.

Religion has not eradicated them, but science, by tracing them to their source in our brute ancestry, has explained them and has shown them in their true light.

As each recognises that the anti-social tendencies are the bestial tendencies in man, and that man in evolving further must evolve out of these, each also feels it part of his personal duty to curb these in himself, and so to rise further from the brute.

This rational 'co-operation with Nature' distinguishes the scientific from the religious person, and this constraining sense of obligation is becoming stronger and stronger in all those who, in losing faith in God, have gained hope for man."[21] For this rational setting of oneself on the side of the forces working for evolution implied active co-operation by personal purity and nobility." To the Atheist it seems that the knowledge that the perfecting of the race is only possible by the improvement of the individual, supplies the most constraining motive which can be imagined for efforts after personal perfection.
