"Nature has placed
mankind under the
governance of two
sovereign masters
pleasure and pain"
"It is for them alone to point out what we
ought to do as well as to determine what
we shall do"
Bentham believed that human
beings are motivated by
pleasure and pain.
Bentham believed that
pleasure is the ultimate
motivator.
All humans pursue pleasure and seek to
avoid pain. Pleasure is the sole good and
pain is the sole evil
The hedonic calculus
The hedonic calculus is a
quantitive assessment of a
situation
Immediacy
We should bear in mind how distant
the anticipated benefits of each possible
course of action are. The more distant the
beenfits the less weight we should give
them in making our decision.
Succession
The likelihood that the pleasure or pain
will be followed by more pleasure or pain .
Whether the pleasure or pain is followed
by more pleasure or pain should effect
your decision.
Duration
Longer lasting pleasure is
preferred over pleasure only
lasting a short period of time.
Certainty
The probability of the pleasure
resulting from the act.Will it
definitely bring pleasure of only
possibly bring pleasure.
Extent
The more people that enjoy
the pleasure the better.
Intenisity
Mild pleasure is less valuabale than
intense pleasure. Acts leading to the
latter are preferred to the former acts.
Purity
An act that causes only pleasure is better
than one that causes the same amount of
pleasure mixed with a little pain.
To calculate the greatest happiness for the
greatest number, you will need to determine
and predict the amount of happiness that will be
produced from each action. From this
calculation you can then determine which
action to take as the one that creates the most
happiness is the right one. The way in which a
utilitarian would calculate this would be to use
the following categories.
Principle of utility
Bentham believed that the
rightness or wrongness of an
action was judged by its utility or
usefulness to produce pleasure.
The act that produces the most
happiness is the most moral.
Mill's utilitarianism
Mill's life
Mill was heavily influenced by
Bentham from an early age.
Mill has been linked to the
creation of modern feminism
Mill is considered one of the greatest and
the most influential British philosopher of
the nineteenth century.
Mill adjusted Bentham's
theory of utilitarianism
J.S Mill
Mill believed that the
well-being of an
individual was
heightened when the
individual is able to
pursue their own end.
Mill believed that the well-being
of any one person was the most
important deciding factor in any
decision made.
Quality over quantity
Distinguishes the difference between higher and lower
pleasures. That some pleasures were worth more than others.
Pleasures of the mind were more valuable then pleasures of the
body.
Mill believed that gaining a higher
pleasure should be considered better
than one without even if the person
gained some sadness from the action
taken.
"It is better to be a human being
dissatisfied than a pig satisfied.
Better to be socrates dissatisfied
then a fool satisfied "
"Human beings have more than
animal desires and once we
know that we do not regard
anything as true happiness that
include satisfaction of those
desires"
Strengths and weaknesses
of Mill's Utilitarianism
Strengths
It takes the situation into account
while still maximising the
importance of the individual.
Mill's utilitarianism is supported by christrian believes.
The idea of higher and lower pleasures
gives more justification
Weaknesses
The idea of pleasure and pain is subjective.
Not everyone is capable of determining the
probability of consequences of actions.
There is no strict definitiion of what higher and lower pleasures are.
Strengths and weaknesses of
Bentham's Utilitarianism
Weaknesses
Impractical
It is impractical to suggest
that we have time to
deliberate and apply the
calculus to every situation
we come across especially
as we may not have the full
information.
Strengths
Intuitively correct
It is intuitively correct becuase
common sense dictates that all
situations are not identical and
sometimes a different approach is
needed.
Yard Stick
Bentham created the principle of
utility as a method of social reform.
It is a way of testing a law for its
utility for human kind. If it does not
meet the goals of a human then
Bentham argued the law should be
changed.
Cultural diversity
It takes into account cultural
diversity. Each culture is allowed to
operate equally and in parallel
without one being considered more
superior than the other.
Humanistic
It seeks to
maximise a human
goal, its basis is
therefore
grounded in
humanity and does
not seek authority
from another
source.
Act, Rule and Preference
utilitarianism
Act
An act utilitarian would want to decide what
action would lead to the greatest good and
apply the principle of utility directly.
Consequential
Relative
Telelogical
Weaknesses and
strengths of act
utilitarianism
Weaknesses
There is the potential to
justify any act.
It is difficult to predict
the consequences .
Strengths
Act utilitarianism can be
universally used.
The hedonic calclus is clearly
structured and culturally relative.
Jeremy
Bentham
Rule
Relative
Deontological
Consequential
A rule utilitarian would
judge the action by the
good-ness or badness of the
action for everyone involved.
Strengths and weaknesses
of rule utilitarianism
Strengths
Encourages people to be
kinder to produce
maximum happiness
Encourages people
to aim for higher
pleasures
Weaknesses
There is no clear
guidance
Rule utilitarianism does
not look into an individuals
Mill
Preference
Hare
Singer
Telelogical
A preference utilitarian judges actions
on being morally right or wrong
according to whether or not it fits to
preferences of all involved.
Strengths and weaknesses of preference utilitarianism
Strengths
Allows a person to make a
personal decision.
Choices do not be effected by others opinions.
Weaknesses
Som people are
incapable of making
their own decisions.
There are no set guidelines
that can be followed
The individuals decision may
not benefit the mass.
Peter Singer
Singer is an Australian philosophy. He was one of the
main theorists in bringing about the newest form of
utilitarianism, preference utilitarianism.
Hare
R.M Hare was an English philosophy. He along with Singer was
one of the main theorists in creating preference utilitarianism.
Bentham worked on
legal reforms and wrote
the principles of morals
and legislations in 1789
Born in London at a
time of great
scientific and social
change.
Demands were being made for greater
democracy and better human rights.
