>>12480Utilitarism
In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number.
Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts
The principle of utility does not mean that any given pleasure, as music, for instance, or any given exemption from pain, as for example health, are to be looked upon as means to a collective something termed happiness, and to be desired on that account. They are desired and desirable in and for themselves; besides being means, they are a part of the end. Virtue, according to the utilitarian doctrine, is not naturally and originally part of the end, but it is capable of becoming so; and in those who love it disinterestedly it has become so, and is desired and cherished, not as a means to happiness, but as a part of their happiness
involves our saying, for instance, that a world in which absolutely nothing except pleasure existed—no knowledge, no love, no enjoyment of beauty, no moral qualities—must yet be intrinsically better—better worth creating—provided only the total quantity of pleasure in it were the least bit greater, than one in which all these things existed as well as pleasure. It involves our saying that, even if the total quantity of pleasure in each was exactly equal, yet the fact that all the beings in the one possessed, in addition knowledge of many different kinds and a full appreciation of all that was beautiful or worthy of love in their world, whereas none of the beings in the other possessed any of these things, would give us no reason whatever for preferring the former to the latter.
Act utilitarianism:
Act utilitarianism is a utilitarian theory of ethics that states that a person's act is morally right if and only if it produces the best possible results in that specific situation
To understand how act utilitarianism works, compare the consequences of watching television all day tomorrow to the consequences of doing charity work tomorrow. One could produce more overall happiness in the world by doing charity work tomorrow than by watching television all day tomorrow. According to act utilitarianism, then, the right thing to do tomorrow is to go out and do charity work; it is wrong to stay home and watch television all day.
Rule utilitarianism:
Rule utilitarianism is a form of utilitarianism that says an action is right as it conforms to a rule that leads to the greatest good, or that "the rightness or wrongness of a particular action is a function of the correctness of the rule of which it is an instance".
For rule utilitarians, the correctness of a rule is determined by the amount of good it brings about when followed. In contrast, act utilitarians judge an act in terms of the consequences of that act alone (such as stopping at a red light), rather than judging whether it faithfully adhered to the rule of which it was an instance (such as, "always stop at red lights"). Rule utilitarians argue that following rules that tend to lead to the greatest good will have better consequences overall than allowing exceptions to be made in individual instances, even if better consequences can be demonstrated in those instances.
