Utilitarianism

John Stuart and Harriet Taylor Mill
She was a great influence on his intellectual work; some have suggested that she was in fact a co-author.
The intution behind utilitarianism is that what makes an act right or wrong is its effect on human happiness or welfare. The morality of anything we do should be judged by whether it makes people better off or worse off. What counts as "welfare" or "happiness" is something over which utilitarians differ. The most influential version of utilitarianism is that given by the 19th century English philosopher, John Stuart Mill. He called his thesis "The Greatest Happiness Principle," and it defined welfare or happiness as pleasure. The major competitors to this view are (a) a view that says that welfare is measured by the extent to which one has his or her desires satisfied and (b) a view descending from Aristotle which holds that welfare is a kind of flourishing or thriving, doing well in one’s life overall. See
Aristotelean Ethics for an idea of what he thought this flourishing was.The Greatest Happiness Principle
: [the GHP] :Actions are preferable
1 in proportion as they tend2 to produce3 the greatest balance4 of pleasure5 over pain for all6 , undesirable insofar as they tend to produce the greatest balance of pain over pleasure for all.GLOSS:
[1] The GHP is prescriptive: it tells us what we should do
[2] The GHP assesses how much pleasure/pain an action tends to produce, that is the pleasure or pain caused by an action of that type, or the pleasure/pain caused by that kind of action as a rule, NOT how much pain/pleasure will be produced by that particular act in this time at this place.. (So if I want to know whether I should lie, I ask: What does my experience tell me the results usually are if people lie in similar circumstances, NOT what will be the result if I lie this time.)
ACT UTILITARIANISM: We judge the rightness or wrongness of an act by the actual consequences that it produces.
RULE UTILITARIANISM: We judge the rightness or wrongness of an act by the typical or usual consequences of doing that kind of act.
[3] the GHP judges the rightness and wrongness of acts by what they produce, by their consequences, not by any characteristic of the act itself. So no matter what kind of act we’re evaluating from lying to rape, whether that kind of act is right or wrong depends on the consequences that flow from it. A utilitarian cannot say that lying or rape are just plain wrong, no further questions. The wrongness or rightness of any kind of act is always conditional on how things turn out.
[4] It is not the action that tends to produce the most pleasure that is to be chosen, but that which tends to produce the greatest balance of pleasure over pain. An action that produces a great deal of pleasure but also a great deal of pain would not be preferred over an action that produced less pleasure but no pain at all.
[5] Happiness=pleasure or absence of pain. Mill is a hedonist. Other utilitarians consider that other things are good, not pleasure, or not just pleasure.
[6] : It is the pleasure of all that counts, not just my pleasure. Who counts as "all?" All sentient beings, all beings capable of feeling pleasure and pain, which includes some animals.
So when an ACT-UTILITARIAN is trying to determine what s/he morally ought to do:
1. She determines what the options are before her.
(and there may be several something else's that could be done.)
2. For each option, she calculates the costs and benefits to all those who are affected by it.
3. She then subtracts the costs from the benefits.
4. She compares this net amount with the net amount for the other options.
5. The right thing to do is the option that has the greatest balance of benefits over cost. If she is in the unfortunate position where all her options have greater costs than benefits, the right thing to do is the option that has causes the smallest balance of cost over benefit.
When a RULE-UTILITARIAN is trying to determine what he morally ought to do.
1. He determines what kinds of acts are possible for him to do in this situation and then he formulates the various general rules that cover those kinds of acts.
(and there may be several other kinds of act that could be done in situations like this.)
2. For each rule, he then calculates the likely or usual or expected costs and benefits to everyone affected of everyone following it in similar situations.
3. He then subtracts the likely or typical or expected costs of following each rule from the likely or typical or expected benefits of following it
4. He compares this net amount with the net amount for the other rules.
5. The right rule is the one that has the greatest balance of benefits over cost of everyone following it. If he is in the unfortunate position where all the rules have greater costs than benefits, the right rule is the one that has the smallest balance of costs over benefits of everyone following it.
6. The right thing to do in this situation is the act that the right rule says you should do. (This is true even if an act-utilitarian calculation would say to do something else.)
