Classical Theories in Normative Ethics
Three
Different
Types of Ethical Theories
The ethical theories
that philosophers have advanced fall into three main groups. To
understand these different types, one needs to think about the
different types of moral or ethical judgments, broadly conceived, that
people make.
1. Everyday Moral/Ethical
Judgments
Question: What are some
of the different types of ethical judgments, broadly conceived, that
people make?
The expression “different types”
is not the most precise expression, since we can divide things up into
different types either by means of very broad categories, or by very
fine grained ones. What I have in mind here is a division based
upon categories that are as broad as possible.
One thing that people certainly
do is to make judgments about the actions of people, and that’s
certainly a broad category. So we characterize actions as right
and wrong, we say that someone should or shouldn’t have done something,
or that something was a good thing to do, or a bad thing to do.
Do we make moral judgments about
things other than actions?
Well, we also make moral
judgments about people. We say that people like Hitler and Stalin
were very bad people – or that they were evil people – and that other
people are very good people.
So we make moral judgments about
actions, and about people. Are there any other broad categories
of things that we make ethical judgments about?
Another category – a slightly
less obvious one, I think – is that of traits of character.
Consider traits of character like being an honest person, or being a
loving person, or a person who keeps his or her promises. We
think of these as good traits to have, while we think of traits such as
that of being a cruel person, or a dishonest person, or an unfaithful
person as bad traits to have. Or we speak about virtues and vices.
We have, then, at least these
three broad categories of moral judgments, based on the things that we
make moral judgments about:
(1) Moral judgments about actions being right or wrong;
(2) Moral judgments about people being good or bad;
(3) Moral judgments about traits of character being good or bad, being
virtues or vices.
Is there any other type of
ethical judgment, broadly conceived? The answer is that there is,
and it is an extremely important one. But before going on to
consider what that might be, let us focus on the three categories that
we have noticed so far, and think about the following questions:
(a) Are these three types of judgments all independent of one another,
or are they somehow logically related?
(b) If they are logically related, how are they related? Is one
of these three categories more fundamental than the other two, so
ethical judgments of those other two types can be analyzed in terms of
ethical judgments of the more fundamental type?
Here, for example, is a possible
view, and one that some philosophers appear to accept:
1. Of the three types of ethical judgments we have considered so
far, the fundamental ones are those that are about traits of character,
about virtues and vices.
2. Talk about the good or badness of people can then be analyzed
in terms of judgments about the goodness or badness of traits of
character. At least as a starting point, then, one might say:
A person is a good person to the extent that they possess good traits
of character rather than bad ones, and a bad person to the extent that
they possess bad traits of character rather than good ones.
3. Similarly, talk about the rightness and wrongness of actions
can be analyzed in terms of judgments about the goodness or badness of
traits of character. In particular, the following sort of
analysis might be suggested:
An action of a certain type T is a morally
right action if and only if there is some virtuous trait of character C such
that people with that virtuous character trait C are disposed to perform actions of type
T.
An action of a certain type T is a morally
wrong action if and only if there is some bad trait of character C such that
people with that bad character trait C are disposed to perform actions of type
T.
What is one to say about this
theory? Does it seem right that of the three types of ethical
judgments we have considered so far, it is judgments about the goodness
or badness of traits of character that are logically the most
basic? What alternative view (or views) might be proposed
here? Which seems to you the most plausible?
2. Another, Very Important Type
of Evaluative Judgment
There is, however, another type
of ethical judgment, broadly conceived – one might speak of an
evaluative judgment – that one tends not to think of when one talks
about morality or ethics, but that is very important. To see what
it is, ask yourself whether there are things other than actions,
people, and traits of character that one refers to as good or bad.
Consider the following:
“How was the party? Was it a good one?”
“Today was a bad day for Sue. Everything went wrong that could
have gone wrong.”
“Bruce was a nice person, but he had a rather bad life, with lots of
unhappiness and suffering, and some tragic events.”
“That plane crash was really bad.”
In these sentences, the terms
“good” and “bad” are being applied not to actions, nor to people, nor
to traits of character. They are being applied to things like
occurrences, or events, or parts of a person’s life, or a person’s life
as a whole.
Moreover, it would seem that such
judgments can be applied to situations that do not involve any people
at all. Compare, for example, the following two possible worlds:
World 1: A world that
contains no human beings or other intelligent beings, but that does
contain plants and animals, all of which are herbivores.
World 2: A world that is
just the same as World 1 with respect to the types of plants and
herbivores that it contains, but that rather that containing only
herbivores, contains a large number of carnivores as well, as well as
many more natural disasters, such as forest fires.
So World 2 will contain much more
pain than World 1, with various animals being hunted down and killed by
other animals, and animals dying painfully in things like forest
fires. Doesn’t one want to say, then, that World 1 is a world
that is better than World 2?
The basic idea, then, is that in
addition to ethical or evaluative judgments concerning the goodness or
badness of people, the rightness and wrongness of actions, the goodness
or badness of traits of character, one also has:
Judgments or propositions about the goodness
or badness of events and states of affairs, about the desirability or undesirability of such things.
3. One of the Most Fundamental
Questions in Meta-Ethics
We are now in a position to
consider one of the most important, and one of the most fundamental
questions in meta-ethics. It concerns the relation between
evaluative judgments or propositions of the final sort just mentioned,
and evaluative judgments or propositions of the other three types
considered earlier.
To simplify things, suppose that
one decided that as regards ethical judgments or propositions about
actions, people, and traits of character, the basic judgments or
propositions were those concerning actions, asserting that certain
actions were morally right, or morally wrong, or morally permissible,
or morally obligatory, that certain actions should or should not be
done, or may be done. The questions that are crucial are then as
follows:
(1) Are judgments or propositions about the rightness and wrongness of
actions logically more basic than judgments about the good and badness,
the desirability or undesirability, of events and states of affairs, or
is it the other way around, with the latter being more
fundamental? Or are both types of judgments fundamental?
(2) If one of these two types is more fundamental, which one is it, and
how is the other type of judgment related to that more fundamental
type?
How might one of these two
types of judgments be related to the other? One possibility is
that judgments or propositions about the rightness or wrongness of
actions might be fundamental, and judgments or propositions about the
goodness or badness of states of affairs might be analyzed in one of
the following ways:
“A state of affairs of type S is good” =def.
“One ought to bring about states of affairs of type S.”
Or perhaps:
“A state of affairs of type S is good” =def.
“One ought not to destroy states of affairs of type S.”
Suppose instead that it is
judgments or propositions the goodness or badness of states of affairs
that are fundamental. Then judgments or propositions about the
rightness or wrongness of actions might be analyzed as follows:
“Action S is morally right” =def.
“Among the possibilities open to one, action S is the one that produces
the best balance of good states of affairs over bad states of affairs.”
“Action S is morally wrong” =def.
“Among the possibilities open to one, action S is not the one that
produces the best balance of good states of affairs over bad states of
affairs.”
We’ll consider the pros and cons
of these alternative views later on. But, offhand, do you have a
clear preference for either of these views?
4. Three Main Types of
Ethical Theory: Consequentialist Theories, Deontological
Theories, and Virtue Theories
Different views as to which type
of ethical statement is the most fundamental give rise to different
sorts of ethical theories. So let us consider the three main
possibilities have taken seriously.
(1) Consequentialist Theories
Consequentialist theories
maintain that the fundamental ethical judgments involve claims about
what states of affairs are intrinsically good and intrinsically
bad. The idea then is that an action's being wrong can be
analyzed along the lines just mentioned, that is, in terms of its not
being the action that, among those that are open to one, produces the
best balance of good effects over bad effects.
At this point, there is a crucial
idea that needs to be introduced, namely, the idea of something’s being
intrinsically good, or intrinsically bad – or,
alternatively, of something’s being good
in itself, or bad in itself.
Consider, for example, the experiences that one typically has when one
visits a dentist. They are not usually experiences that one would
choose to undergo unless one thought that things would be better later
on than they would be if one did not see the dentist. Visiting
the dentist is therefore instrumentally
good; it is good as a means
either to something else that is desirable, or as a means to something
else that is even more undesirable, such as a lot of future pain.
The idea then is that if something is desirable as a means, if
something is instrumentally valuable, then it must be because is either
brings about some state of affairs that is good in itself, good independently of its consequences,
or because it is a means of avoiding about some state of affairs that
is bad in itself, bad independently of its consequences.
One has then the crucial ideas of states of affairs that are intrinsically good and intrinsically bad, and this gives
rise to the following very important ethical questions:
(1) What types of states of affairs are intrinsically good?
(2) What types of states of affairs are
intrinsically bad?
Discussion of these Two Questions
What are some possible answers to question (1)?
Pleasure? Friendship? Freedom to act? Knowledge,
perhaps of certain types? Great works of art? Development
of a morally good character? A relationship with God?
What are some possible answers to question (2)?
Pain? Ignorance of important truths? Development of a
morally bad character? Lack of a relationship with God?
Given the idea of intrinsically good and
intrinsically bad states of affairs, let us now return to considering
consequentialist approaches to morality.
A Famous Consequentialist
Theory: Utilitarianism
The most famous consequentialist
theory is utilitarianism. This theory comes in different
versions. Some versions maintain that the only thing that is intrinsically good, or good in itself, is pleasure, and the only thing that is
intrinsically bad is pain. So to determine the
moral status of an action, what one considers the total quantity of pleasure that the action
produces, and the total quantity
of pain that it produces. The better the balance of the former
over the latter, the better the action is, and the action with the best
balance of pleasure over pain is the action that one should perform.
If this view is right, then other
things that are valuable are only
instrumentally valuable. So things like friendship,
knowledge of various sorts, great works of art, and so, are valuable
only because they give rise to pleasure, or to a reduction in pain.
This version of utilitarianism
was advanced by Jeremy Bentham (1748-1832). Bentham entered
Oxford at the age of 12, and graduated at the age of 15, and then went
on to study law. Rather than practicing law, however, he worked
on the tasks of developing a better legal system, and of reforming both
criminal and civil law. His work had a very great impact upon
legal theory.
Bentham's approach to ethics was
then both adopted, and modified, by many philosophers. Two of the
earliest were James Mill (1773-1836), and his son, John Stuart Mill
(1806-1873). The latter is the author of Utilitarianism,
certainly the best-known exposition of utilitarianism, and still widely
read today.
In his book Utilitarianism, John Stuart Mill
argued that one could maintain, as Bentham had, that the only thing
that is intrinsically good is pleasure, and the only thing that is
intrinsically bad is pain, without agreeing with Bentham that all that
mattered was the quantity of the pleasure or pain. Thus Mill said,
"It is quite compatible with the principle of utility to recognize that
some kinds of pleasure are more desirable and more valuable than
others. In estimating ·the value of· anything else, we
take into account quality as well as quantity; it would be absurd if
the value of pleasures were supposed to depend on quantity alone."
This immediately leads, of
course, to the question that Mill immediately went on to ask, and
answer:
"What do you mean by 'difference of quality in pleasures'? What,
according to you, makes one pleasure more valuable than another, merely
as a pleasure, if not its being greater in amount?’ There is only one
possible answer to this.
Pleasure P1 is more desirable than pleasure P2 if: all or almost all
people who have had experience of both give a decided preference to P1,
irrespective of any feeling that they ought to prefer it.
If those who are competently acquainted with both these pleasures place
P1 so far above P2 that they prefer it even when they know that a
greater amount of discontent will come with it, and wouldn’t give it up
in exchange for any quantity of P2 that they are capable of having, we
are justified in ascribing to P1 a superiority in quality that so
greatly outweighs quantity as to make quantity comparatively
negligible." (Jonathan Bennett’s translation, p. 6)
Then a little later (p. 7), there
is Mill’s famous remark:
"It is better to be a human being dissatisfied than a pig satisfied;
better to be Socrates dissatisfied than a fool satisfied. And if the
fool or the pig think otherwise, that is because they know only their
own side of the question. The other party to the comparison knows both
sides."
Mill’s answer to the question of
what it means to say that one pleasure is qualitatively better than another
one is interesting. But one can also ask what it is for one
pleasure to be quantitatively greater
than another, and the question is whether there is any way of answering
that question other than by also appealing to what people who are
familiar with both pleasures would choose.
It’s not exactly clear, then,
that Mill’s distinction between quantitative and qualitative
differences in pleasures makes sense. If not, then one could view
the above passages from Mill as really providing an account of what it
is for one pleasure to be quantitatively
greater than another.
Two other, fairly closely related
versions of utilitarianism are worth mentioning. First of all,
one can jettison the ideas of pleasure and pain in favor of the ideas
of happiness and unhappiness,
and hold that the only thing that is intrinsically
good is happiness, and
that the only thing that is intrinsically
bad is unhappiness.
One then needs to offer an account of what happiness and unhappiness
are, if this is not to be explained simply in terms of pleasure and
pain.
A final version of utilitarianism maintain
that the only thing that is intrinsically
good is getting what one wants, having
one’s desires satisfied, and that the only thing that is intrinsically bad is not getting
what one wants, not having one’s
desires satisfied.
But, it might be objected, aren’t
pleasure and pain very closely related to the satisfaction and
non-satisfaction of one’s desires? The answer is that this isn’t
so. Many people, especially in America, for example, have a very
strong desire to be extremely wealthy. They would be willing, for
example, to spend, say, two years in solitary confinement if they would
receive a few million dollars at the end of those two years. Yet
many such people may virtually never think about the fact that they are
not extremely wealthy, and, even when they do, will not be in
pain. So not having a very strong desire satisfied is not
identical with, nor even closely related to, being in pain.
This form of utilitarianism is
often referred to as preference
satisfaction utilitarianism, in contrast to what is referred to
as the hedonistic
utilitarianism of Bentham. The preference satisfaction
utilitarian agrees with hedonistic utilitarian that pleasure is
intrinsically good and pain is intrinsically good, but he or she
maintains that pleasure is intrinsically good pleasure is, by
definition, simply a sensation that one intrinsically desires, while
pain is, by definition, simply a sensation whose absence one
intrinsically desires. So pleasure is intrinsically good
precisely because one is getting what one intrinsically wants, while
pain is intrinsically bad precisely because one is getting what one
intrinsically does not want. But pleasure and pain are not the
only things that are intrinsically significant, since one can have
desires for things other than sensations.
Given an account of what states are intrinsically good and what states
are intrinsically bad, the utilitarian claims that the rightness of an
action is related to the good or badness of its consequences.
Though here, too, there is a split between two rather different
approaches, referred to as
(1) Act utilitarianism, and
(2) Rule utilitarianism.
Act utilitarianism maintains that
the rightness and wrongness of an action is a matter of how the
consequences of the action compare with the consequences of the other
actions that the person could have performed: the right action is the
one with the best consequences, the best balance of good effects over
bad effects.
Rule utilitarianism, in contrast,
maintains that the consideration of consequences is relevant, not in
choosing an individual action, but in deciding upon moral rules.
The correct moral rules are those rules that are such that if people
follow them, the best consequences will result overall, over the long
term. The right action to perform in a given situation,
accordingly, is not the action that will have the best consequences in
that situation: the right action, rather, is the action that conforms
to the moral rules that are the best moral rules - in the sense just
explained.
Non-Utilitarian Forms of
Consequentialism
A distinctive characteristic of
utilitarianism in all of its forms is that it is held that there is only one thing that is intrinsically
good and only one thing that
is intrinsically bad. If one maintained, instead, that there were two or more things that were
intrinsically good or two or more
things that were intrinsically bad, then one have to say how to weight
those different things against one another. So if one held, for
example, that both pleasure and friendship are intrinsically good, the
question would arise as to how valuable friendship was in comparison
with pleasure, and it might well be difficult to find a non-arbitrary answer to that
question.
Could there be a non-utilitarian
form of consequentialism that there is only one thing that is
intrinsically good and only one thing that is intrinsically bad?
The difficulty would be that it is surely true either that non-sadistic
pleasures are intrinsically good, or that the satisfaction of harmless
desires is intrinsically good, and the question is how one could
account for this in terms of some other type of thing that is
intrinsically good.
The upshot is that it seems
likely non-utilitarian forms of consequentialism will have to be what
one might call non-monistic
theories, according to which either that there are two or more things that are
intrinsically good or that there are two
or more things that are intrinsically bad, or both, and so will
face the comparison issue mentioned earlier.
(2) Deontological Theories
The most important alternative to
consequentialist theories is what are known as “deontological”
theories. (The term “deontology” comes from a Greek word that
means, “what is binding”.) Deontological theories maintain
that statements about what one ought to do cannot be explained in terms
of statements about the goodness and badness of consequences.
In support of this claim,
advocates of deontological approaches often argue that individuals have rights, and that it is wrong to
violate those rights simply on the grounds that doing so will lead to a
better balance of good states of affairs over bad states of affairs.
A possible argument for deontological
theories, and against consequentialist theories involves the case of a
brilliant doctor – call her Mary, and it runs as follows:
Mary is stranded on a desert island, and that she has five patients who
need various organ transplants if they are to live: one needs a heart
transplant, one a liver transplant, one a lungs transplant, one a
kidney transplant, and one a pancreas transplant. Unfortunately,
no organs are available, so it looks as if Mary cannot do anything to
save her five patients. But then it occurs to her that she has a
healthy patient, and that that person could be a source of the needed
organs. So Mary kills the healthy patient, and uses that person’s
organs to save the lives of the five patients who would otherwise die.
The question was whether Mary
acted wrongly or not? If she did, then it would seem that at
least act consequentialist positions must be false, since Mary by
choosing to kill one patient to save five, chose the action with the
better consequences.
Many people are inclined to say
that what Mary did was wrong. But as we also saw, when one shifts
to some cases that appear to be related – such as the trolley case
where one can save five people by steering a trolley onto another
track, where it will kill only one person, people sometimes have
intuitions that conflict with their intuitions in the doctor case.
To return to the characterization
of deontological theories, such moral theories generally feel that some
or all of the following concepts are of ethical importance:
(a) the idea of individual rights;
(b) the idea that someone deserves,
or does not deserve something;
(c) the idea of fairness;
(d) the idea of a reasonably equitable
distribution.
(a) has been illustrated by the
case of the doctor, but could be illustrated by many other cases as
well. Consider, for example, massive redistribution of the
world's wealth.
For (b), consider the case of
deciding who should get a TV set that is to be given away: a friendly
grandmother, or a mass murderer. (Suppose that it would give the
murderer more happiness than the grandmother.)
For (c) and (d), consider a
parent who consistently gives nicer presents to one of her children
than she gives to the others. (Again, we can suppose that more
happiness is produced by this way of doing things.)
Some Varieties of Deontological
Theories
One of the big divides in the
case of deontological theories is that between those that postulate a
number of unrelated principles concerning what actions are right and
what actions are wrong. A philosopher named W. D. Ross
(1877-1971), for example, maintained that people had a number of what
he referred to as “prima facie duties”. Thus, in his book The Right and the Good (1930), Ross
listed the following seven prima facie duties:
(1) The obligation to be faithful, including the obligation to keep
one’s promises;
(2) The obligation of reparation – the obligation to repay others when
one has harmed them;
(3) The obligation of gratitude;
(4) The obligation of non-maleficence – that is, not to harm others;
(5) The obligation to treat others fairly and justly;
(6) The obligation of beneficence – that is, to help and benefit
others; and
(7) The obligation to improve oneself.
As in the case of non-monistic
consequentialist theories, when one holds that there are several
different factors that are morally significant, the question arises as
to how they are weighted. So Ross is faced with the question of
saying how these various duties compare with one another in strength.
A famous deontological theory
that attempts to avoid this problem is that offered by the German
philosopher (1724-1804). Kant set out his moral theory in
different places, one of which you have read parts of: The Foundations of the Metaphysics of
Morals. There Kant attempt to set out a principle from
which all moral duties can be derived. His first formulation of
that principle is as follows:
“Act as though the maxim of your
action were to become, through your will, a universal law of nature.”
(Jonathan Bennett’s translation, p. 24)
Then, later on, Kant offers two other formulations of what he takes to
be the fundamental principle of morality:
“Act in such a way as to treat
humanity, whether in your own person or in that of anyone else, always
as an end and never merely as a means.” (Jonathan Bennett’s
translation, p. 29)
“Act only so that your will could
regard itself as giving universal law through its maxim.”
(Jonathan Bennett’s translation, p. 32)
One problem here is that while the first and
the third formulations seem fairly closely related, the second
formulation looks very different, and it is not easy to see how one can
get from the first formulation to the second, and Kant’s attempt to do
so does not seem to me at all satisfactory.
The main problem, however, is concerned with how one
can derive any specific duties from any of these three
formulations. Thus John Stuart Mill, in Utilitarianism,
commenting on Kant’s approach, says,
"This remarkable man, whose system of thought will long remain one of
the landmarks in the history of philosophical thought, lays down in
that treatise a universal first principle as the origin and ground of
moral obligation:
Act in such a way that the rule on which you act could be adopted as a
law by all rational beings.
But when he begins to derive any of the actual duties of morality from
this principle he fails, almost grotesquely, to show that there would
be any contradiction—any logical impossibility, or even any physical
impossibility—in the adoption by all rational beings of the most
outrageously immoral rules of conduct. All he shows is that the
universal adoption of such rules would have consequences that no one
would choose to bring about." (Jonathan Bennett’s translation, p.
3)
Thus Kant attempts to show, by appealing to his
first formulation, that suicide
is morally wrong, and claims that one could not will that everyone
should commit suicide. But surely there is, as Mill would say of
this particular case, nothing that is either logically impossible or
physically impossible about willing that everyone commit suicide.
All that is true is that that everyone’s committing suicide would be a
very undesirable outcome.
(3) Virtue Theories
The third main type of ethical
theory that is being discussed by philosophers today is what is called
“virtue theory.” This type of theory goes back to the beginning
of philosophy in Athens, and you have read parts of Aristotle’s Nicomachean Ethics, where Aristotle
sets out a virtue theory approach.
The distinction between virtue
theories and deontological theories does not seem as great as that
between either of these theories, on the one hand, and consequentialist
theories on the other. For it would seem that for any moral rule,
one can postulate both a corresponding, virtuous trait of character,
and a corresponding vice. Similarly, for any virtuous trait of
character, and the corresponding vice, one can postulate a
corresponding moral rule. So it seems that there is a one-to-one
mapping from one to the other. One has for example:
Moral Rule
Virtue
Vice
One should not lie.
Being
honest Being a liar
But if this can be done, then the
implications of a given virtue theory with regard to what one ought to
do will coincide
with the implications of the corresponding deontological theory.
So the difference between deontological theories and virtue theories
does not seem all that important. By contrast, consequentialist
theories, such as utilitarianism, often have quite radical conclusions
about what actions are right and what actions are wrong.
Still, one can ask about whether, if one rejects
consequentialism, one should go with a virtue theory or a deontological
theory, and it is not easy to see what to say here. One thing is
that virtue theories are not monistic
theories: a number of virtues are postulated – and in some cases, quite
a large number – so that a deontological theory that derives everything
from a single moral rule – or at least a very small number – will be
intellectually more illuminating.
Aristotle, in his Nicomachean
Ethics, did offer a general characterization of virtues, holding
that every virtue was a mean between two extremes, the extremes being
vices. Thus he described courage as a mean between cowardice on
the one hand, and rashness (or foolishness) on the other. But I
don’t think that this characterization, if it were right, would really
help one to pick out the virtues, since I think a trait can be
intermediate between two other traits, without being a virtue.
Consider, for example, the extremes of wanting to stick to the same routine, and wanting as much
variety as possible. Neither of these traits seems to me to be a
vice, nor does it seem that there is a virtue that lies between
them. So being a mean between two extreme is not a sufficient
condition of being a virtue. Nor does it appear to be a necessary
condition. For consider the virtues of being honest, or being faithful. What, in each of
these cases, are the two vices that the virtue in question is
intermediate between?
