Critiques of Utilitarianism
A common objection dismissed:
Objection: If there are 101 people, Util. says
that 51 of them can do whatever they want
to the other 50 as long as that makes them
happy.
No it doesn’t. (1) the unhappiness caused by
deprivation must be factored in and (2)
there are actions open that produce more
happiness.
Some Other common challenges:
• Time (it takes too long to do a utilitarian calculus)
– Most decisions are easy and obvious. Many others are quickly
enough made with brief thought, still others do allow time for
extended thought. For those issues requiring time that is not
available, we must hope our moral habits are good enough.
• Inconsistency (utilitarianism is too situational)
– One theory’s inconsistency is another theory’s flexibility. To
some extent we want our moral theories to be able to consider
actions taken in different circumstances in different ways.
• Uncertainty (shouldn’t we know if an action is moral
when we do it?)
– It is true that some are better at anticipating consequences than
others, however, nobody is excused from attempting to do so.
People are often held responsible for outcomes they did not
intend. The Util. says this is less a problem with utilitarianism
than a problem with reality.
Utilitarianism is too
overriding/demanding
• According to a strict interpretation of Util.
you must give up any luxury possessions
you have until the point of marginal utility
(that is, give until just before it hurts). It
may well be that morality demands this of
us, but the extremity of this position gives
many pause.
• See “Famine, Affluence, and Morality” by
Peter Singer
Utilitarianism is too impartial
• Imagine a scenario in which a stranger is
drowning, and so is your spouse. You only
have time to reach one of them.
• The solution to this dilemma seems
obvious to most, but Util. provides no
basis for the obvious answer.
• Bernard Williams criticizes the Utilitarian in
this situation for having “One thought too
many”.
Utilitarianism is a poor basis for
rules
• To consider Hospers’ tax evasion case, it
appears that the way to optimize utility is
not to have everybody follow the law, but
instead to make sure that as many people
break the law as possible without
collapsing the system.
• All rules appear to have this character in a
Utilitarian system.
A problem with aggregating utility
• Utilizing a method of
maximizing total utility
in a fully utilitarian
society leads to what
is called “The
reprehensible
conclusion” which
advocates as many
people as possible
living at the bare
minimum.
• Utilizing a method of
maximizing average
utility in a fully
utilitarian society
leads to what is called
“The dastardly
conclusion” in which a
number of people
sacrifice themselves
to improve the
average.
