The fundamental definition of maximizing consequentialism is
that the objectively right action is the action, among available alternatives,
that maximizes net good consequences. Do barely happy multitudes and utility
monsters mean that consequentialism so understood cannot provide the
fundamental guiding principle of morality?
1 Maximizing the
average or median.
Happiness is the most common candidate for the good. For
simplicity, I am going follow the majority here and take happiness to be what
the consequentialist wants to maximize. Having particularized that much, I will
feel free to use “utility” and “utilitarianism,” these terms often being
employed in place of “the good” and “consequentialism” especially by those who
take happiness or pleasure to be the consequential good. For a little
additional simplicity, I am going to assume that the subjects in whose
happiness we are interested are human beings.
Next we need to specify the math of the maximization of the happiness
of human beings. Is it total happiness over the whole population, or average
happiness, or median happiness or one of many other alternatives?
At this step the problems arise. Consider the maximization
of average happiness. Suppose there is someone in the population capable of
experiencing very great happiness – much more happiness than we ordinary folks.
In the literature, such persons are called “utility monsters.” Average consequentialism, then, would
apparently recommend pruning all the other members of the population whose
existence does not contribute materially to the happiness of the monster. After
all, the others just bring down the average.
Although total and average good are the usual candidates for
what consequentialism is to maximize, I am going to take a quick look at a couple
of other functions on the good, which can stand proxy for many more. Even
without a utility monster, person-pruning would typically be recommended for
median as well as average happiness. Eliminating those less happy than the
median person, assuming they do not contribute materially to either that
person’s happiness or those who would potentially become median, moves the
median up to happier and happier people.
Maximizing the happiness of the least happy person,
distantly related to a principle of Rawls, would hardly be a candidate for the
expression of consequentialist insight. It is interesting to note, however,
that it runs into the same problem. If we want a maximally happy least happy
person, homicide is again an obvious expedient. Subject to certain details
about interpersonal relationships and retaining enough people to keep the
society functioning, eliminating a large chunk of the population may well
result in a least happy person who is quite happy. Similar reasoning applies to
any percentile on the happiness ladder.
2. Read this section only if you have consequentialist concerns about
consequentialist genocide; otherwise skip to 3.
If you are reading this section, you may have doubts that
consequentialism could really promote the “pruning” of living persons in
support of a better average or median or minimum. Killings, after all, are generally un-utilitarian.
They erase all the future happiness that the victim would have had, and,
especially if there are as many of them as average happiness consequentialism
and its cousins might require, they could fill society in general with terror
and loathing.
However, erasure of the future happiness of the happiness-deficient
is exactly the point. Once that happiness quantity is off the books, the
average or median happiness goes up.
As for terror and loathing, they would have to be taken into
account in a real world exercise. One way of minimizing these dis-utilities
would be propaganda celebrating the superiority of consequentialism in the form
being enforced. Those who are less happy, it could be inculcated, ought to be
eliminated. They deserve it for bringing down the average or median happiness.
Repugnant as these rationalizations for murder are, single-minded
real world consequentialists are not going to toss them from their toolbox. We
have seen horrible, but quite effective, racist and nationalist propaganda not
very different from this.
A second way of dealing with eliminations for the greater
average or median good combines some mix of secrecy and fraud. If a loner is not seen again or if everyone
but a few insiders thinks a death is the result of an aneurysm or a freak
accident, terror and loathing can be minimized, at least until the numbers of
disappearances, aneurysms, and freak accidents become too large.
These practical patches would, I think it is safe to say,
only be partially successful, and hence the eliminations would, for
consequential reasons, have to be somewhat less sweeping than the worst
imaginable case.
In any event, however, this is all an unnecessary detour away
from our purely theoretical investigation. A consequentialism of averages can
license murder in the service of a utility monster, or a new median, by virtue
of the convention, long recognized in philosophy, that philosophical hypotheticals
are frictionless. If the existence of A is not logically inconsistent with the
existence of B, then I am allowed put them together in a philosophical counterexample.
It is a thought experiment, after all, not an engineering drawing. Maybe a
utility monster is not a biological possibility, and a society that puts up
with person-pruning is not anthropologically, sociologically, or politically
possible. The rocket scientists cannot produce spaceships capable of closing
towards each other at nearly the speed of light, but that does not stop us from
equipping the twins of their famous “paradox” with such vehicles.
Moreover, our real
worry about average happiness consequentialism nags forcefully before we even
start thinking about such details as terror and loathing.
Suppose that an average good month gives you and me 30
utiles of happiness. Anthropologists find an isolated mountain village of 50
persons. In a typical month, they enjoy about 100 utiles each. On another side
of the mountain lives a hermit, U. M. who is deliriously happy at all times.
The utility meter only goes up to 10,000, but the loud click with which it slams
into the top pin suggests that U.M.’s monthly happiness far exceeds 10,000.
On
yet a third side of the mountain is a community whose members are not very
happy. Their economists tell them that if they follow one set of policies, they
will evolve, over several generations, towards the happiness level of the first
community with roughly their own existing level of population. Other policies,
including birth control, but no killings, will eventually lead them to a U.M.
like personage, self-perpetuated by cloning. Consistent average utilitarians should
argue that the villagers should follow the second set of policies.
If you disagree, then we do not have to worry
about the more distressing sorts of average utility pruning to conclude against
the average good consequentialists and their cousins.
3. Maximizing the
total.
Planet A has a billion (109) inhabitants, each of
whom enjoys roughly 100 utiles per month.
Planet B has a trillion (1012 ) inhabitants , each of whom
enjoys 1 utile per month. It is just barely a life worth living. B has ten times more total happiness than
A. Has there ever been a
consequentialist who would think B truly has the better of it?
4. Can consequentialism be correct?
So the most obvious candidates for what it is to maximize
the good can come into severe conflict with our intuitions, even when we focus our
intuitions on the good a la
consequentialism. Can consequentialism
yet claim to provide the principle of
right action? Here are some conceivable
arguments in support of an affirmative answer.
5. An anti-genocide
rider for average good consequentialism?
The horrible I have paraded out to discredit the average
good version of consequentialism is a utility monster aided and abetted by
homicidal consequentialists. Similar parades take place early in the
consequentialist module of many classes on ethical theory. Isn’t it obvious,
however, that we should call a halt to this dystopia-mongering by simply
adopting a proviso prohibiting the taking of human life?
This won’t work for two reasons: first, the utility monster problem
would reappear without murderous prunings; second, and far more important, the
proviso would be un-consequentialist.
As we have already seen birth control population measures
favoring utility monsters can lead to as consequentially unintuitive results as
death camps. We will shortly see another, more pedestrian case, where the
proviso would not cure the utility monster problem of average utilitarianism.
From the side of theory, however, the decisive objection to
the proviso is that it is alien to consequentialism. “Don’t kill even if it maximizes the good” is
obviously a non-consequentialist, i.e. a deontological, principle. At the end
of the day, consequentialism may well need to be hemmed in by deontology for all
sorts of reasons. Here, however, my concern is whether, in the face of such
problems as utility monsters and barely happy multitudes, consequentialism can
still claim to provide the
fundamental moral principle. For that question, consequentialism can rely on nothing
beyond its own resources.
5. An alternative
technical definition of greatest good.
Perhaps there is a mathematical formula that will mix in a
little total good consequentialism with the average good version so as to
preserve the attractive features of each while suppressing their worst case applications.
In looking for such a formula, I am not going to take as a starting point total
happiness. It is not happiness itself we
are interested in, but happy people. That we can produce unlimited happiness by
crowding in ever more barely net happy people shows a fundamental defect in
total good consequentialism. By contrast, the utility monster sort of problem
seems as if it might be philosophical sleight of hand, directing our attention
away from a roughly sound idea.
So is there formula that retains the virtues of average good
consequentialism but vanquishes utility monsters and related devices? A first thought is that the formula should
somehow deflate the utiles count of the monsters. We certainly would like such
a deflation when population policy is in question, most imperatively when offing is in the offing.
However, it is far from obvious that we want to deflate a utility
monster’s utility in every case. Suppose the question is whether to subsidize
the training of opera singers or the training of jockeys. (Of course, there
should be a vote about this, but I am assuming that all our voters are average-good
utilitarians. So each voter will be concerned with the question whether or not
a deflator should be applied for averaging purposes to the happiness of the utility
monster among them.)
I submit that we don’t yet know. It will depend upon the monster.
All the initial definition tells us it that a utility monster is capable of
being, and generally is, preternaturally happy. That is what is important for
population policy. For the present purpose, however, we need to know, at a
minimum, about the sensitivity of the monster’s happiness to such external
environmental changes as a dearth or plenitude of singers or jockeys.
Suppose that the utility monster is super-sensitive to
changes in the opera scene. Although enormously happy in any case, the monster
is very disappointed when exposed to second rate bel canto. The decrease in monster utility is so great as to swamp
the gains and losses of happiness in the rest of the population relative to the
singer versus jockey choice. Here, it may well be, a deflator would be in order.
In an opposite scenario the celestial happiness of the
monster might be affected by matters of the opera house or race track only by
roughly the same number of utiles as any ordinary opera or race fan. The
monster will remain ecstatic, with only a small percentage change in that ecstasy
however the singer-jockey question is resolved. So the monster’s preferences
will affect the average, but no more than do those of anyone else. No deflator
would be appropriate.
We could use a deflator only for people whose utility
differential between singers and jockey’s was greater than some preset figure –
a figure well in access of the median differential. Yet is this fair to the
dedicated opera and track aficionados?
If you care too much about something, your happiness or unhappiness
should get capped for utilitarian purposes? In addition to its utter
arbitrariness, such caps, again seem, again, un-consequentialist.
Rough as this is, it is enough to make me doubt that any formula for adjusting the way the averaging of
utility is to be done will work satisfactorily in all situations. The intuitively
right way to average in a particular case is going to depend too much on
details about the utility monster, or otherwise about the spread of
preferences, as well as details about the choice alternatives.
6. Satisficing
instead of maximizing consequentialism?
Some theorists (Simon, Slote, Pettit) have argued for a
consequentialism that seeks not the alternative that maximizes the good but an alternative that is good enough. The chief virtue of this version of consequentialism
is supposed to be that it is not as demanding as the maximizing forms. To do at
every decision point the very best thing for the global good really does ask
quite a lot of us.
It might be thought that satisficing consequentialism also
solves the problems of utility monsters and barely happy multitudes. A policy
that forswore shrinking population down to a small group of utility monsters
might yet be good enough, even though it would not maximize average utility.
Similarly a policy might well be good enough even if it did not maximize total
utility with a trillion barely happy people.
Still, if we want to satisfice with respect to average
happiness, utility monsters will once again pose a threat to the theory. It is
not that they force a dramatically pro-monster solution. Satisficing reduces
drama with respect to what is required.
Still, it has no such affect upon what is permitted.
Policies that do not winnow the population down to the utility monsters are
going to be good enough, but so are policies that do winnow.
Of course genocide in the service of utility monsters is not
really “good enough,” not being good at all.
Its obvious not-good-enough-ness, we may suspect, comes from
deontological principles sounding in equal moral worth. This is not, then, an interpretation
of “good enough” available to satisficing average good consequentialism, and so
that theory remains stuck with the permissibility of genocide.
As you anticipate, the same thing is true of satisficing
total utility consequentialism. It may be that a total quantity of utility less
than that of the barely happy individuals of the multitude will be good enough
for the satisficing total utility consequentialist, and that some of those
alternatives will have many fewer people and a greater average utility.
However, if total utility is what we are seeking to satisfice, then the
trillion barely happy individuals will also be good enough if that is what
maximizes total utility. The decision maker may choose one of the higher
average utility options, but that would either be on a whim or because of some
moral consideration other than satisficing total utility.
The move from maximizing to satisficing does not solve the
problems.
7. But
consequentialism is a practical, real world, moral methodology for which
utility monsters and trillion person planets are as irrelevant as multiple
spatial dimensions and talking giraffes!
Purported paradoxes from fantastic thought examples will not
keep anyone from being guided by consequentialist considerations in everyday
life. Can you remember any policy discussion lasting more than two minutes without
better or worse consequences being advanced in argument? Rarely, if ever, do those
discussions turn on whether average good or total good is in question, and
utility monsters have never been caught sight of outside philosophy classrooms.
I am not wholly unsympathetic to this objection. Still, that
we are so comfortable with consequential reasoning is no reason to avoid examining
its deep structure and justification. The average utility and total utility
problems cast doubt on the claim that, at bottom, morality equals consequentialism.
Utility monsters and barely happy multitudes seem to show that morality must
look to sources that are not consequentialist and sometimes conflict with and
limit consequentialism.
8. Conclusion
In this light, I do not see how we can give much credence to
the claim that consequentialism provides the final answer for the fundamental
question of moral theory. Even if we are agnostic as to exactly what is the
deep structure of morality, we should bear the deficiencies of consequentialist
theory in mind when its practical prescriptions clash with our intuitions.
For, example, there is Bentham’s view that criminal sentencing should maximize the utility of the society. This seems initially plausible and would unquestionably license much less severe penalties than most of the current sentencing in the United States. Given the concerns about the fundamentals of consequentialism, we might canvass our intuitions about potential punishment reforms.

Here is one. Society might well be happier if we sentenced
all convicted shoplifters, including first offenders, to life without parole. Shoplifting
would then be mostly deterred. It would not be entirely deterred. I once had a
client who could probably have purchased the high end store from which they
lifted a hundred dollar item. I doubt, however, that said client would have
been deterred by the prospect of being conveyed immediately from the shop door
to the gallows. (The client, I should add, was perfectly sane and competent
under existing legal definitions in most US jurisdictions.)
The near elimination of almost all shoplifting losses would
be a very great economic gain, the benefits of which would be widely
distributed. The collection of all those
who would have committed shoplifting under the old law would especially
benefit. Of course, a few of them would still get caught shoplifting and their subsequent
lives would be miserable. Those who were successfully deterred and
spared a shoplifting conviction, however, would likely lead much happier lives,
and they would vastly outnumber those who would shoplift in the face of the
draconian penalty.
Yet, even if it produced clear net positive utility, I have
a strong intuition, which I suspect you share, that it would be wrong to
sentence first time shoplifters to life terms.
Sometimes, as Rawls argued, moral intuitions can be modified
or overthrown if they conflict with an otherwise sound and well supported
theory. Utility monsters and barely happy multitudes give us reason to doubt
the soundness of consequentialism at its foundations and so weaken its force
against our intuitions in such cases as life terms for shoplifters.
