In obedience to the laws of Natural Selection, the males fight for the most attractive females, and keep as many as they can, and form societies on that basis.
But man has a sense of justice, and mercy, and gratitude, and love.

Here is an animal who knows he ought to tell truth, and do right, and honor his parents, and respect and love his brethren.

Whether he always does his duty or not, he feels and owns he ought to do it.

Justice, and mercy, and the fear of God, are not at all the attributes of brutes, and never could have been produced by the evolution of their instincts.

No animal possesses any knowledge of God, nor practices any form of religious worship.
