The document discusses utilitarianism and Bentham's act utilitarian theory. It provides an overview of key concepts in Bentham's theory, including the principle of utility which states an action is right if it promotes the greatest happiness for the greatest number. Bentham believed happiness was equivalent to pleasure and pain avoidance. His hedonic calculus provided a method to measure pleasure and pain from consequences to determine a morally right action. The document also discusses strengths and weaknesses of Bentham's utilitarian approach.

Utilitarianism: a brief introduction
• A teleological theory. But, what does
this mean?
• Teleological theories look at the
consequences- the results of an action-
to decide whether it is right or wrong.
• Consequentialist theory- someone who
decides whether an action is good or
bad by its consequences.

Jeremy Bentham (1748-1832)
• He was concerned with
social and legal reform & he
wanted to develop an ethical
theory which established
whether something was
good or bad according to its
benefit for the majority of
people.
• He called this the principle of
utility.
• Utility = the usefulness of
the results of actions.

Bentham: main points
• Bentham equated happiness with pleasure and the
absence of pain.
• This was an empirical observation - people desire
pleasure and seek to avoid pain.
• His scientific mind led him to believe that the study of
ethics could be undertaken in a practical way,
carefully measuring the possible consequences or
outcomes of an action before deciding which choice
to take.
• Bentham’s theories led to extensive social reform
affecting Parliament, criminal law, the jury system,
prisons, savings banks, and cheap postage.
• Bentham believed in equality: all people “to count as
one and no-one as more than one” when making
laws. His hedonic calculus was especially helpful in
determining how to measure different amounts of
pleasure.

Principle of Utility: deriving the norm
Often expressed as
“the greatest good of the
greatest number”
Good = happiness or pleasure. So, an act is right or
wrong according to the good or bad results that results
from the act and the good act is the most pleasurable.
Quantitative= focuses on the greatest number.

Principle of Utility: applying the norm
• The theory is based on ancient hedonism
(pleasure seeking), which pursued physical
pleasure and avoided physical pain.
• Moral acts= maximise pleasure/ minimise
pain    utilitarian calculus.
• So, an act = moral, if it brings the greatest
amount of pleasure and least pain.
• Problem: suppose I think pain is good and
pleasure bad, like the Puritans or Da Vinci
Code flagellant?

Bentham: applying the norm contd
• The principle of utility aims to promote happiness
which is the supreme ethical value.
“Nature has placed us under the governance of
two sovereign masters, pain and pleasure.”
An act is ‘right’ if it delivers more pleasure than pain
and ‘wrong’ if it brings about more pain than
pleasure.
• Simple equation 
Happiness = pleasure minus pain.

12. October 12, 2015 philosophicalinvestigations.co.uk
Problem: Are happiness and pleasure the
same?
• “Actions are right in proportion
when they tend to promote
happiness, wrong when they
tend to produce the reverse of
happiness.”
• According to Bentham's
theory, the rightness of an
action entirely depends on the
value of its consequences.
That is why the theory is also
described as consequentialist.
• Problem: are happiness and
pleasure the same thing?

Exercise: think of four features
of hedonism (pleasure-seeking)
HEDONISM

14. October 12, 2015 philosophicalinvestigations.co.uk
Historical basis in Greek philosophy
• Utilitarianism  a Hedonistic theory.
• This is based on the idea that ‘good’ is defined in
terms of pleasure/ happiness.
• Greek Philosophers-- Plato and Aristotle both argued
that ‘good’ equated with the greatest happiness (BUT
eudaimonia is a richer idea = flourishing).
• While Epicureans stressed pleasure as the main aim
of life.
• Pleasure is NOT the same as happiness, as
happiness results from the use of reason and
cultivating the virtues to produce eudaimonia or
flourishing.
• It is only if we take pleasure in good activities that
pleasure itself is good.

Exercise: You have 30 happiness points
to distribute across nine things.
• Draw four columns marked “activity, my
score, average score, happy/sad?”
• Put these nine in the first column: clothes,
family, sport, religion, romance, study,
money, freedom. Allocate your points in col2
• Work out class average for col. 3.
• If that average is imposed on you, will you be
happy or sad (compare col 2 and 3)?

Problem with utilitarianism
• What does this exercise suggest might
be a problem with utilitarianism? (Think
of Government policy on health,
education)
• See Jonathan Glover’s quote (on this
site, go to utilitarianism/evaluative
quotes)

Bentham’s hedonic calculus
Helps us choose the good thing to do and work out the
possible consequences of an action.
P.R.R.I.C.E.D = acronym.
• Purity – how free from pain is it?
• Remoteness – how near is it?
• Richness*– to what extent will it lead to other pleasures?
• Intensity – how powerful is it?
• Certainty – how likely it is to result in pleasure?
• Extent – how many people does it affect?
• Duration – how long will it last?
* Note: Bentham calls richness fecundity

Now: apply this to euthanasia
• Bentham's Hedonic Calculus can be used to weigh
up the pleasure and pain caused by two courses of
action - in this case, helping someone to die, or not
doing so.
• Bentham would consider the Intensity of the pain and
its Duration. He would have to weigh that against the
number of people affected (Extent), and consider
whether keeping someone alive would lead to other
pleasures (Richness). He would also need to add up
the amount of other 'pains' the patient would face e.g.
loss of dignity (Purity), and consider the chances that
there' might be a cure or treatment in the future
(Certainty). The pain is immediate, while possible
future benefits are Remote.
• In most cases, the degree of pain is so great that
Bentham's theory would support euthanasia.

A theory of Motivation
• According to Bentham, the key
psychological motivation is pleasure
and avoidance of pain.
• Duty was not important, as in Kantian
Ethics.
• Rules are not important, as Mill
suggested.
Q. what’s wrong with putting pleasure at
the centre of your ethics?

Exercise: write an answer to these points
1. Are all actions only good because they have good results?
2. Suppose a surgeon could use the organs of one healthy patient to
save the lives of several others. Would the surgeon be justified in
killing the healthy patient for the sake of the others? NHS decisions?
3. Suppose an assault is committed that is thought to be racially
motivated. Riots are brewing that may result in many deaths and long
term racial antagonism. You are the police chief and have recently
taken a man into custody. Why not frame him? He will be imprisoned if
found guilty and this will result in peace and safety. Only you, the
innocent man and the real criminal (who will keep quiet), will know the
truth. What is the morally right thing to do? Similar to the case of
Rachel Nickel’s alleged killer, Colin Stagg, convicted though innocent
4. You are an army officer who has just captured an enemy soldier who
knows where a secret time bomb is planted. If it explodes it will kill
thousands. Will it be morally permissible to torture the solider so that
he reveals the bomb’s location?
If you knew where the soldier's children were, would it also be
permissible to torture them to get him to reveal the bomb’s
whereabouts? Similar to US Government policy of rendition (removing
terror suspects to countries that torture) following 9/11.

Wrap up Bentham
• On the piece of paper/ post it note, write one thing
you have learned today…
• Could be a concept you are now familiar with.
• Or, a new key term in your vocabulary.
• A theory that you are more confident in
understanding.
• Developed an academic/exam skill.
• If nothing, be honest. But say why you feel nothing.
