The law of heredity has long been suspected, and, in late years, has been, to a considerable extent, regarded as the demonstrated and universal order of nature. It is the law by which the offspring inherits the qualities and characteristics of its ancestors. It makes the oak the same sort of a tree as the parent, from which the seed acorn fell. It makes a tree, which sprang from the seed of a large peach, yield downy fruit as large and luscious as the juicy ancestor. It says that every thing shall produce after its kind; that small radishes shall come from the seed of small radishes, and a richly perfumed geranium from the slip cut from one of that kind. It says that, other things being equal, the descendants of a fast horse shall be fast, and the posterity of a plug shall be plugs. It says that a Jersey cow, with thin ears, straight back, and copious yield of rich milk, shall have children like unto herself. But a man has many more qualities and possibilities than a vegetable or a brute. He has an infinitely wider range, through which his characteristics may run. The color of his hair, his size, his strength, are but the smallest part of his inheritance. He inherits also the size and texture of his brain, the shape of his skull, and the skill of his hands. It is among his ancestry that must be sought the reason and source of his powers. It is there that is largely determined the question of his capacity for ideas, and it is from his ancestry that a man should form his ideas of his capacity. It is there that are largely settled the matters of his tastes and temper, of his ambitions and his powers. The question of whether he shall be a mechanic, a tradesman, or a lawyer, is already settled before he gets a chance at the problem. The old myth about the gods holding a council at the birth of every mortal, and determining his destiny, has some truth in it. In one respect it is wrong. The council of the gods is held years before his birth; it has been in session all the time. If a man has musical skill, he gets it from his ancestry. It is the same with an inventor, or an artist, or a scholar, or a preacher. This looks like the law of fate. It is not. It is the fate of law. But this is not all of the law of inheritance. Men have an inherited moral nature, as well as an intellectual one. Drunkenness, sensuality, laziness, extravagance, and pauperism, are handed down from father to son. Appetites are inherited, and so are habits. On the other hand, courage, energy, self-denial, the power of work, are also transmitted and inherited. If a man’s ancestry were thieves, it will not do to trust him. If they were bold, true, honest men and women, it will do to rely upon him.
