Major Ethical Theories
UtilitarianismKantian ethicsRights
A Major Misunderstanding
One must “declare allegiance” to one ethical theory in order to “do” ethics
Arguments undermining all known ethical theories collectively make it plain that there is no theoretical basis for ethical thought at all
A Better Understanding
A & S, p. 9Human life and behavior is
exceedingly complexTo be workable as a theory or model,
must be simpler than real lifeTherefore, any one theory will have
gaps and blind spots but may be good partial description of the moral life
A Helpful Metaphor?
Approach each ethical problem as a job
Ethical theories are tools in your tool box which you bring to the work
Part of job is picking the right tools to perform that job well
Utilitarianism
Core Idea: Ethics should be based on facts about the results of our actions upon human happiness and suffering in the real world
Facts for Utilitarianism
What counts as human happiness or unhappiness
Actual probability that a particular action will produce a certain amount or type of happiness or unhappiness
Utilitarianism as Ethics
Fact: Most of us act most of the time as if we count for more than others
To be an ethical system, utilitarianism must insist that all count equally
Utilitarianism
Do what produces the greatest net gain in happiness over unhappiness (the greatest good) for the greatest number of people
Crude Utilitarianism
A&S, p. 14: All right to kill one innocent person if organs would save lives of five others
Ignores long term consequencesIgnores subtle consequencesIgnores ripple effects
Classical Utilitarianism
J.S. Mill, 1840-1860All human values or disvalues can be
reduced to happiness or unhappiness, and these can be measured quantitatively (“utilitarian calculus”)
Objection: Different human values seem to be of radically different types, not simply different quantities
Preference Utilitarianism
E.g., Peter SingerWhat is right is to perform the act
which maximizes the value preferences that are achieved for the greatest number of people (I.e., the most people possible get more of what they value)
Criticisms of Utilitarianism
Do not show that it has no valueInstead show its natural and
necessary limits and weaknesses (I.e., for what jobs it is less well suited as a tool of inquiry)
Major Criticisms
“One thought too many” Utilitarianism as too weak an ethical
theory“Utilitarians can’t rent videos”
Utilitarianism as too stringent an ethical theory
Shogun Example
British sailor is being tortured alive Japanese samurai stands in moonlit
garden and derives great gratification (including sexual) from listening to screams
Is what was done to British sailor wrong?
Examples- cont.
Utilitarian father trying to decide whether to rescue his child vs. any child at random from an immediate danger
Bernard Williams: Father has had “one thought too many” to be an ideally ethical person
Conclusion
Utilitarianism seems especially weak in capturing some of our most basic moral intuitions about:
The injustice of sacrificing the interests of the few for the many
The moral relevance of special relationships
Can’t Rent Videos?
Utilitarianism as too stringent an ethical system if taken literally (so long as any human misery exists anywhere in the world)
How far removed from our everyday, average standard of behavior can/should an ethical theory be?
Kantian Ethics
Core Idea: We can use our reason to discern that some actions are wrong based on the nature of the action and apart from its practical consequences
Kant: What is ethics?
“If you want to get more of Y, then you should do X” (hypothetical imperative)
“Do X” (categorical imperative)
Possible Sources for Ethics (Kant)
FACTS Changing, unstable Yields only hypothetical imperatives
“PURE REASON” (Logic) Eternal, universal Gives rise to categorical imperative
Logic (pure reason)
Sam is unmarried
All bachelors are unmarried
Categorical Imperative
“Act so as always to treat others as ends-in-themselves and never as means only”
“Act so that you could will your action to become universal law”
Two ways to express the same basic idea (Kant)
Why are two the same?
Could one will the opposite of “treat others as ends and never as means only” to be universal law?
If so, I should treat others as means only
Then others should treat me as means only
But I have willed this to be universal law
Why are two the same? (II)
But only an “end-in-itself” (possessed of autonomous will) could will something to be universal law
Therefore willing opposite leads to logical contradiction
Therefore “treat others as ends…” is categorical imperative
Illustration: Tell the Truth
Should I tell a lie?Can I will lying to become universal law?If lying were universal practice, “truth”
would no longer have any meaningBut if “truth” has no meaning neither
does “lying”Logical contradiction as universal law
Common Terminology
Utilitarianism is a consequentialist ethical theory
Kantianism is a deontological (duty-based) ethical theory
For Kant, source of duty is the concept of autonomy and rational will (pure reason as source of ethical duty)
Rights Theory
Dworkin: Rights as “trumps”Nozick: “Side constraints”Most of the time we are entitled to
try to maximize the good consequences of our actions
A right takes priority over maximizing the good (line you can’t cross even to get to a good place)
Two Ways to Cheapen Rights
Invoke your “rights” whenever anyone interferes with your getting anything you happen to want
Be willing to rescind the rights of others whenever they act in ways that you happen not to like
Libertarianism
Distinguish:Positive right: a right to have or
obtain something (other people have to do something)
Negative right: a right to be free of something (other people have to not do something)
Libertarianism
State power may be used only to protect negative rights
Any state power to protect positive rights is wrong, because it must violate someone else’s negative rights to be free of seizure of property
Critique of Libertarianism
Right to trial by juryRequires that numerous services be
provided and that various institutions have to be established
Most of these require support in terms of salaries, maintenance costs, etc.
A great deal of tax money is needed
Critique of Libertarianism
This means a right to trial by jury is a positive right
BUT: usually viewed as a negative right, I.e. right to be free from unfair imprisonment or punishment
Does whether it is positive or negative determine how important or how basic it is?
Critique of Libertarianism
Some positive rights may be absolutely vital and well worth protecting
Some negative rights may be unimportant or superficial and may not be worth protecting
Some redistribution of resources among people in society is an inevitable function of the state
