Energy is the working power in all achievement. Inert coal, it converts into fire, and water it transmutes into steam; it vivifies and intensifies the commonest talent until it approaches to genius, and when it touches the mind of the dullard, it turns into a living fire that which before was sleeping in inertia.

Energy is a moral virtue, its opposing vice being laziness. As a virtue, it can be cultivated, and the lazy man can become energetic by forcibly arousing himself to exertion. Compared with the energetic man, the lazy man is not half alive. Even while the latter is talking about the difficult of doing a thing, the former is doing it. The active man has done a considerable amount of work before the lazy man has roused himself from sleep. While the lazy man is waiting for an opportunity, the active man has gone out, and met and utilized half a dozen opportunities. He does things while the other is rubbing his eyes.

Energy is one of the primary forces: without it nothing can be accomplished. It is the basic element in all forms of action. The entire universe is a manifestation of tireless, though inscrutable energy. Energy is, indeed, life, and without it there would be no universe, no life. When a man has ceased to act, when the body lies inert, and all the functions have ceased to act, then we say he is dead; and in so far as a man fails to act, he is so far dead. Man, mentally and physically, is framed for action, and not for swinish ease. Every muscle of the body (being a lever for exertion) is a rebuke to the lazy man. Every bone and nerve is fashioned for resistance; every function and faculty is there for a legitimate use. All things have their end in action; all things are perfected in use.
