Introduction to Ethical Theory

Page 2: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Why Survey Ethical Theory At All?

Different Aims in Different Courses

– In a course on ethical theory

In order to investigate what the correct theory is

– In a course like this

In order to acquire some tools to work with

The survey identifies a number of perspectives that should be taken into account when considering ethically difficult cases

Page 3: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Relativism vs. Objectivism Again

Last week, we primarily considered moral relativism

Remember relativism is not just a descriptive theory. It’s a normative theory.

– It claims not just that people’s moral beliefs differ, but that all there is to the moral facts is the beliefs held in a particular culture.

– What’s right = what a culture believes is right

This week we’ll focus on objectivism

Page 4: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Moral Objectivism

• 'Moral facts' are like 'physical facts'.

• What the facts are is independent of what anyone thinks

• They have to be discovered like the laws of physics

• Discovery may be difficult (again, compare to physics)

• Note: Believing in objectivism doesn’t mean you know what the moral facts are

Page 5: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Why Focus on Objectivism?

A glib answer:

– Our culture places importance on justifying our moral beliefs.

It says we should, morally speaking, defend those beliefs.

– As such, even if relativism is true, it seems we’re morally obligated to defend our beliefs as though there were objective facts to uncover

Page 6: Philosophy 2803 – Lecture II Introduction to Ethical Theory

What Are the Objective Facts?

Suppose for the moments that objectivism is true. What are the objective facts of morality?

Three Candidates:

– Consequentialism– Deontological Theories– Principilism

See text for other examples

Page 7: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Case #1

X, an emergency room physician, happens upon a roadside accident. A car has crashed leaving 4 people seriously hurt

After calling 911, X begins examining the injuries of the 4 people

All are in danger of dying if they don’t receive immediate attention.

A quick examination reveals that one person, K, will require so much attention the other three may well die before he finishes treating K

If K is left until last, his life is in serious danger, but X will likely be able to save the other three

Page 8: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Consequentialism

Consequentialists maintain that whether an action is morally right or wrong depends on the action's consequences. 

– In any situation, the morally right thing to do is whatever will have the best consequences.

– E.g., save 3 people, rather than 1

Consequentialist theories are sometimes called teleological theories.

Page 9: Philosophy 2803 – Lecture II Introduction to Ethical Theory

What Kind of Consequences?

Consequentialism isn't very informative unless it's combined with a theory about what the best consequences are.

E.g., Creedism =

consequentialism + the theory that consequences should be assessed in terms of how they reflect on the career of Creed

Good for Creed = good consequences

Page 10: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Utilitarianism

Utilitarianism is the most influential variety of consequentialism

The 'Founders' of Utilitarianism

– Jeremy Bentham (1748-1832) – John Stuart Mill (1806-1873)

The Basis of Utilitarianism:  ask what has intrinsic value and assess the consequences of an action in terms of intrinsically valuable things.

Page 11: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Jeremy Bentham

Page 12: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Intrinsic vs. Instrumental Value

Instrumental Value - a thing has only instrumental value if it is only valuable for what it may get you

– e.g., money

Intrinsic Value - a thing has intrinsic value if you value it for itself

– i.e., you’d value it even if it brought you nothing else– It may, however, also possess instrumental value

What, if anything, has intrinsic value?

Page 13: Philosophy 2803 – Lecture II Introduction to Ethical Theory

What Has Intrinsic Value?

What Utilitarians Think Is Intrinsically Valuable:  happiness

– Actually, not all utilitarians agree that happiness is quite the right way of putting this. 

– Other suggestions include satisfaction, well-being, pleasure. (See text)

– Each variation yields a slightly different theory

– For now, the general approach is what matters

Page 14: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The ‘Greatest Happiness Principle’

"actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness.“ (John Stuart Mill)

– In other words, judge an action by the total amount of happiness and unhappiness it creates

– Note: this means the total happiness (and unhappiness) of everyone affected

Page 15: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Act vs. Rule Utilitarianism

Notice that the GHP is a little vague. 

it's not clear whether Mill means

– (i) an action is right if this sort of action tends to promote happiness or

– (ii) an action is right if this particular action will promote happiness.

If you believe in version i, you're a Rule Utilitarian. If you believe in version ii, you're an Act Utilitarian.

Page 16: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Case #2

X has inoperable lung cancer that is unresponsive to chemotherapy & radiation therapy

X will most likely die within one year

X’s physician believes X could not handle this news

X’s physician decides to lie about the diagnosis for a while in order to ‘buy X a little more time’

Page 17: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Deontology

'Duty Based' Ethics

Deontologists deny that what ultimately matters is an action's consequences. 

What matters is the kind of action it is.

What matters is doing our duty.

Identify principle(s) from which our duties arise

Page 18: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Kinds of Deontological Theory

There are many kinds of deontological theory

– e.g., ‘The Golden Rule' - "Do unto others as you'd have them do unto you."

Deontological theories may be identifed as monist or pluralist depending on the number of fundamental principles of duty the theory identifies

– Monist = 1– Pluralist = more than 1– See text for examples of pluralism

Page 19: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Kant

Immanuel Kant (1724-1804) is the most influential deontologist.

Rejecting Consequentialism

"A good will is good not because of what it effects or accomplishes." Even if by bad luck a good person never accomplishes anything much, the good will would "like a jewel, still shine by its own light as something which has its full value in itself."

Page 20: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Categorical Imperative

Kant claims that all our actions should be judged according to a rule he calls the Categorical Imperative. 

First Version:  "Act only according to that maxim [i.e., rule] whereby you can at the same time will that it become a universal law."

– E.g., telling a lie whenever you need to borrow money is morally wrong because this sort of act is not ‘universalizable’. 

– If everyone acted this way, the whole practice of promising to repay a loan would collapse.

Page 21: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Second Version of the C.I.

Second Version (The “practical imperative”): “Act in such a way that you treat humanity, whether in your own person or in the person of another, always at the same time as an end and never simply as a means.”

– Note: Kant is a monist since he thinks both versions of the C.I. ultimately say the same thing

This means there are certain ways we must not treat people (no matter how much utility might be produced by treating them in those ways)

– E.g., don’t lie to a patient

Page 22: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Second Principle & Medical Ethics

The second principle has been very influential in medical ethics

A ‘medical’ reading of this principle

– it is necessary to treat people as autonomous agents capable of making their own decision

Page 23: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Autonomy

A central element in many deontological theories is the idea of autonomy

Autonomy = self + rule

Autonomous decisions are ones which you make for yourself for your own reasons (ideally, your own well-informed reasons)

By respecting your autonomous decisions, we respect you as an ‘end in itself’

Page 24: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Group Work

1. List the strengths of deontology

2. List the weaknesses of deontology

3. List the strengths of consequentialism

4. List the weaknesses of consequentialism

Page 25: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Strengths of Consequentialism

Practical, Results-oriented View

Relatively clear how to make ethical judgments – simply reflect on consequences

Page 26: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Weaknesses of Consequentialism

How can we know all the consequences of an action?

How can we compare utility from person to person?

Do we include all generations?  All species?

Will utilitarianism lead us to ‘repugnant conclusions’?

– In theory, any kind of action could be justified if the consequences of the situation work out just right.

Page 27: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Strengths of Deontology

Sets clear moral boundaries – Some things just can’t be done

Possibility of multiple principles allows for flexibility– Only on pluralist versions of deontology

Page 28: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Weaknesses of Deontology

If we don’t rely on consequences for moral justification, then can we find a convincing case for identifying basic moral principles?– Deontology’s basic approach is not as simple as

consequentialism’s

Deontology can seem overly ‘legalistic’– i.e., too focused on rules– too inflexible

Page 29: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Point

Considerations raised by both theories are worth taking seriously

We’ll close by considering a theory that tries to encompass both: principilism

Page 30: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Principilism

Principilism attempts to have it both ways

Popularized by Beauchamp and Childress

– Principles of Biomedical Ethics (1979)– The ‘Georgetown Mantra’

Now the dominant theory in medical ethics

Page 31: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Four Principles

1. Autonomy 2. Beneficence 3. Non-maleficence 4. Justice

– The text might call this a pluralist deontological theory since it endorses a number of fundamental principles

– I disagree. Conditions 2 & 3 identify this as a hybrid of consequentialism and deontology

Page 32: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Principles

1. Autonomy

– The autonomy of patients (families, co-workers, etc.) must be respected

2. Beneficence

– Help others (i.e., benefit them)

Page 33: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Principles

3. Non-maleficence

– ‘Do no harm’

4. Justice

– “fair, equitable, and appropriate treatment in light of what is due or owed” (Beauchamp & Childress, 2001, 226)

– Treating like cases alike

Page 34: Philosophy 2803 – Lecture II Introduction to Ethical Theory

Assessing Principilism

Note: while this is the orthodox theory in medicine these days, it’s not the be all and end all of medical ethics

Principilism’s virtue: takes consequences and principles seriously

Principilism’s vice: how do we balance consequences and principles when push comes to shove?

– This is a question we’ll confront numerous times in this class

Page 35: Philosophy 2803 – Lecture II Introduction to Ethical Theory

The Point (Again)

As noted, we will not attempt to settle the question of which ethical theory is correct

Think of the theories discussed tonight as identifying viewpoints that must be considered when taking a stand on issues in medical ethics

We must be prepared to consider challenges to our views and arguments from these viewpoints
