ACT UTILITARIANISM VERSUS RULE UTILITARIANISM
Example of Act Utilitarianism
The
Ethical Question: Should we
(i.e., George and I) hack into Danny’s computer, just to see if we can
do it
(i.e., but not harm Danny’s computer)?
Step 1: List
everyone affected by the action.
Step 2: Find out (either by directly asking someone or by using your moral imagination) how much pleasure and/or pain will be involved for every person affected by the action.
Step
3: Do that action that maximizes
happiness for the persons affected by the action.

Result: More

results from doing the action; therefore, we should do the action.
Examples
of RULE Utilitarianism
The
Ethical Question (Simple Example): I have
made a promise to meet a friend who is on his deathbed; should I keep
my
promise?
Step 1: Think
about the KIND or type of action that
the action is.
Step 2: Ponder different rules, considering whether they maximize happiness in general.
Step
3: Do that action based on a rule
that maximizes happiness in general (not necessarily for this action
right
now).
This action
involves
promise keeping, and the rule of keeping promises in general maximizes
happiness.
Result: Since the rule of keeping promises IN GENERAL
maximizes happiness (whether or not it does do that today in this
action), I should keep my promise.
The
Ethical Question (Complex Example): I have
made a promise to meet a friend who is on his deathbed; on my way to
meet him,
I find a woman who is wounded (but curable) and needs my help (no one
else is
around). Should I keep my promise?
These actions involve either promise keeping or helping others, and both keeping promises and helping others maximize happiness in general. Thus, we are faced with a dilemma (see below).
Result: EITHER: One can argue that, since helping the woman is an immediate matter of life and death, and the rule of helping others maximizes happiness IN GENERAL, I should help the woman. OR: One could argue that the rule of keeping promises maximizes happiness, and keep his or her promise. Problem: If we pick the action that maximizes happiness IN THIS CASE, aren't we back to Act Utilitarianism, which makes Rule Utilitarianism pointless? And if we can just pick either rule and be a rule utilitarian, then Rule Utilitarianism is arbitrary - it allows you to do whatever action you wish, as long as you can come up with a rule that seems to maximize happiness in general.
