Should this work be favorably received, the author hopes to prepare, for higher college-classes, a textbook, embracing a more detailed and thorough discussion of the questions at issue among the different schools—past and present—of ethical science. Chapter 1. ACTION. An act or action is a voluntary exercise of any power of body or mind. The character of an action, whether good or bad, depends on the intention of the agent. Thus, if I mean to do my neighbor a kindness by any particular act, the action is kind, and therefore good, on my part, even though he derive no benefit from it, or be injured by it. If I mean to do my neighbor an injury, the action is unkind, and therefore bad, though it do him no harm, or though it even result to his benefit. If I mean to perform an action, good or bad, and am prevented from performing it by some unforeseen hindrance, the act is as truly mine as if I had performed it. Words which have any meaning are actions. So are thoughts which we purposely call up, or retain in the mind. On the other hand, the actions which we are compelled to perform against our wishes, and the thoughts which are forced upon our minds, without our own consent, are not our actions. This is obviously true when our fellow-men forcibly compel us to do or to hear things which we do not wish to do or to hear. It is their action solely, and we have no more part in it than if we were brute beasts, or inanimate objects. It is, then, the intention that gives character to the action. That we commonly do what we intend to do there can be no doubt. We do not act under _immediate_ compulsion. We are, therefore, free _agents_, or actors. But are our intentions free? Is it in our power to will otherwise than we will? When we choose to perform an act that is just or kind, is it in our power to choose to perform an act of the opposite character? In other words, is the _will_ free? If it be not so, then what we call our intentions are not ours, but are to be attributed to the superior will which has given direction to our wills. If God has so arranged the order of nature and the course of events as to force my will in certain directions, good or evil, then it is He that does the good or evil which I seem to do. On this supposition God is the only agent or actor in the universe. Evil, if it be wrought, is wrought by Him alone; and if we cannot admit that the Supreme Being does evil, the only alternative is to deny the existence of evil, and to maintain that what we call evil bears an essential part in the production of good. For instance, if the horrible enormities imputed to Nero were utterly bad, the evil that was in them is chargeable, not on Nero, but on God; or if it be maintained that God cannot do evil, then Nero was an instrument for the advancement of human happiness and well-being. What reasons have we for believing that the human will is free?
