Papers of the American Negro Academy. (The American Negro Academy. Occasional Papers, No. 18-19.‪)‬

It is a Book of History. The book describes that One wrong produces other wrongs as surely and as naturally as the seed of the thorn produces other thorns. Men do not in the moral world gather figs from a thorn-bush any more than they do in the vegetable world. What they sow in either world, that they reap. Such is the law. The earth is bound under all circumstances and conditions of time and place to reproduce life, action, conduct, character, each after its own kind. Men cannot make what is bad bring forth what is good. Truth does not come out of error, light out of darkness, love out of hate, justice out of injustice, liberty out of slavery.
