Consequentialism

• Locates morality entirely in the consequences

• An action is morally right if it generates the best consequences (of the possible courses of action)

• A question for consequentialismo What is meant by consequences?

Jeremy Bentham (1748-1832)

“Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do…”

Page 4: Utilitarianism Ethics Dr. Jason M. Chang. Consequentialism Locates morality entirely in the consequences An action is morally right if it generates the

Jeremy Bentham (1748-1832)

“They govern us in all we do, in all we say, in all we think: every effort

we can make to throw off our subjection, will serve but to demonstrate and confirm it.”

Jeremy Bentham (1748-1832)

“By the principle of utility is meant that principle which approves or

disapproves of every action whatsoever according to the

tendency it appears to have to augment or diminish the

happiness of the party whose interest is in question.”

Principle of Utility

The morally right action is the action that produces the greatest happiness (pleasure) for the greatest number of people.

Features of Utilitarianism

• Everyone affected by action is counted

• Everyone’s happiness counted equally

• Assumes happiness can be quantified

• Consequences include everything that will happen in the world if action is performed

Advantages of Utilitarianism

• Definite method for deriving morally right action

• Reduces moral disagreement

• Makes sense that morality is about consequences

The Queen v. Dudley and Stevens

Page 12: Utilitarianism Ethics Dr. Jason M. Chang. Consequentialism Locates morality entirely in the consequences An action is morally right if it generates the

The Queen v. Dudley and StevensFacts:

• May 19, 1884: The English yacht Mignoette sets sail

• Crew = Dudley, Stephens, Brooks, and Parker the cabin boy

• July 5: Mignoette sunk; crew forced onto lifeboat

• Crew have little food and no drinking water

• July 18: Dudley and Stephens kill Parker

• Crew feeds on Parker’s body and blood

The Queen v. Dudley and Stevens

Analysis:• Issue

o May an innocent person be killed (and eaten) to save the lives of others?

• Argument from Dudley and Stephens’ defense

o Actions committed out of necessity to prevent some greater harm (i.e., the death of all)

o Dudley and Stephens’ action was justified

Page 14: Utilitarianism Ethics Dr. Jason M. Chang. Consequentialism Locates morality entirely in the consequences An action is morally right if it generates the

The Queen v. Dudley and Stevens

Analysis:• Court’s decision

o Killing to prevent greater harm may not be excused when the person killed is innocent

• Court’s reasoningo Allowing killing to prevent greater

harm sets a dangerous precedent

o Cannot compare the value of different human lives

Page 15: Utilitarianism Ethics Dr. Jason M. Chang. Consequentialism Locates morality entirely in the consequences An action is morally right if it generates the

The Queen v. Dudley and Stevens

From the Court’s Opinion:

“By what measure is the comparative value of lives be measured? Is it to be strength, or intellect, or

what? […] In this case the weakest, the youngest, the most unresisting, was chosen. Was

it more necessary to kill him than one of the grown men?”

Ford Pinto Case

Page 17: Utilitarianism Ethics Dr. Jason M. Chang. Consequentialism Locates morality entirely in the consequences An action is morally right if it generates the

Ford Pinto Case

• The Ford Pinto was rushed into production in much less than the usual time.

• Pre-production crash tests showed that rear-end collisions would rupture the car’s fuel system easily

• Ford decided to manufacture the car anyway, even though Ford owned a patent on a much safer gas tank.

• For more than eight years, Ford lobbied against government safety standards that would have forced Ford to change the gas tank.

Ford’s Cost/Benefit Analysis

Benefits of fixing gas tank:

(180 x $200,000) + (180 x $67,000) + (2,100 x $700) = $49.5 million

Costs of fixing gas tank:

12.5 million vehicles x $11 = $137 million

Criticisms of Utilitarianism

• Happiness is difficult to calculateo Especially when having to

calculate value of human lives

• Fails to account for rights and dignity of persons
