Nobody knows through how many thousands of years fighting men have made a place for themselves while the weak and peaceable have gone to the wall.

I observe that there are two entirely different theories according to which individual men seek to get on in the world. One theory leads a man to pull down everybody around him in order to climb up on them to a higher place. The other leads a man to help everybody around him in order that he may go up with them.

Men do not fail; they give up trying

Men do not fail; they give up trying

The law of the survival of the fittest led inevitably to the survival and predominance of the men who were effective in war and who loved it because they were effective.

The limitation upon this mode of promoting peace lies in the fact that it consists in an appeal to the civilized side of man, while war is the product of forces proceeding from man's original savage nature.
