Ethics

Utilitarianism, Kantian Ethics, Natural Rights Theories, and Religious Ethics A “utilitarian” argument, in the strict sense, is one what alleges that we ought to do something because it will produce more total happiness than doing anything else would. Act utilitarianism (AU) is the moral theory that holds that the morally right action, the act that we have a moral duty to do, is the one that will (probably) maximize “utility” (happiness, welfare, well-being). AU is not to be confused with egoism. The egoist really only cares about his own happiness. AU says that everyone’s happiness counts equally. Suppose that executing Joseph would in the long run produce more total happiness than letting him live would. Then according to AU, we ought to execute Joseph. Now if Joseph is a convicted serial murderer who would probably escape and commit more murders if we tried to incarcerate him, then it’s reasonable to think that executing him would be the right thing to do. But what if he has committed no crime? What if he is simply an extremely irritating person with no friends or loved ones, and the many people with whom he has contact in his life are very sensitive and dislike him intensely? Since more total happiness is produced if Joseph dies (the increased happiness of the many who no longer have to endure him outweighs his unhappiness about dying) than if he lives, AU says that it’s right to kill him. This example illustrates what is probably the main objection to AU: it tells us to violate rights/commit injustices when doing so is necessary to produce the greatest total amount of happiness. A “utilitarian” argument in a looser sense is one that alleges that we ought to do something because of its “good consequences” (or not do something because of its “bad consequences”), where good/bad consequences needn’t be limited to what increases or decreases happiness, but might include other things that a strict utilitarian theory attaches no positive or negative intrinsic value
