“Consequentialism and the Argument from Rationality”
Nicolas Maloberti (Bowling Green State University)
ABSTRACT
Deontological theories hold that it is
impermissible to commit an act of an objectionable type even when it is
necessary to minimize the occurrence of acts of the very same type. But how can
the minimization of morally objectionable conduct be morally unacceptable? Some have claimed that deontology contradicts a familiar
conception of rationality and, therefore, that consequentialism ought to be
preferred. The purpose of this paper is to show why this argument for
consequentialism might fail. It is argued that a commitment to a plausible
conception of practical rationality might not entail the rejection of
deontological constraints, as the consequentialist would claim. Contrary to
what others have done, neither the idea of
an impersonal ranking of states of affairs nor the maximizing conception of
rationality is challenged in the process.
Consequentialism
and the Argument from Rationality
It has been claimed that only consequentialism can be
consistent with the demands of practical rationality. The purpose of this paper
is to show why that might not be the case. It is argued that the
non-consequentialist might endorse the same conception of rationality that the
consequentialist does. In other words, it would not be true that a commitment
to a plausible conception of practical rationality entails the rejection of
deontological constraints. It is acknowledged that saving deontological
constraints from the charge of irrationality might entail endorsing an unfamiliar
conception of value. But it is claimed that such a conception would seem to be
more plausible that the counterintuitive judgments that follows from the
non-existence of deontological constraints.
I. The ‘Paradox of Deontology’
A deontological theory is a moral theory affirming the
existence of deontological constraints.
The characteristic feature of such moral restrictions is that we are forbidden
to violate them even when our violation would be necessary to prevent a greater
number of violations. So deontological theories hold that it is impermissible
to commit one act of an objectionable type in order to minimize acts of the
very same type. But how can the minimization of morally objectionable conduct
be morally unacceptable? Robert Nozick discovered this puzzling feature
presenting his own theory:
If nonviolation of C is so important, shouldn't that be
the goal? How can a concern for the nonviolation of C lead to the refusal to violate
C even when this would prevent other more extensive violations of C? What is
the rationale for placing the nonviolation of rights as a side constraint upon
action instead of including it solely as a goal of one's action?[1]
Some years later, in his widely acclaimed book, The Rejection of Consequentialism, Samuel
Scheffler raised this question again.[2]
Nozick had claimed that deontological constraints reflect the Kantian principle
that “individuals are ends and not merely means; they may not be sacrificed or
used for the achieving of other ends without their consent”[3].
Scheffler says that it is natural to interpret Nozick's contention as a
suggestion that violations of deontological constraints involve violating the
victimized individuals themselves, treating them as means instead of ends.[4] But
then, Scheffler would reject the plausibility of Nozick's answer. The reason is
simple: regardless of how high the disvalue of a violation of constraint C is,
Scheffler reminds us that a greater number of equally weighty violations might
take place, and hence at least as much disvalue will ensue if the constraint is
not violated.[5] Scheffler
also claims that it makes no difference which feature of a violation is singled
out as having high disvalue. For nothing one can say about that feature will be
capable of explaining a moral rule denying that it is permissible to minimize
the occurrence of the very same feature.[6] In
The Limits of Morality, Shelly Kagan would
seem to share Scheffler’s diagnosis. After his examination of possible
deontological answers, Kagan concluded: “not only has the [deontologist] failed
to give an adequate explanation; he has failed to give even the beginnings of
one.”[7]
Consequentialism is usually understood as an account
of right action. The right action is the one that produces the highest-ranked
state of affairs in terms of a given conception of the good. On the contrary, deontology could be
understood as maintaining that given any impersonal principle for ranking
overall states of affairs from best to worst, there will be circumstances in
which one is not permitted to produce the best available state of affairs.
Deontology could then be understood as a system of constraints on the
maximization of moral goodness. For deontology, there are limitations on the
conduct of the individual agent which take priority over calculations of
overall impersonal value. The weight given to this priority is such that, at
least sometimes, it is impermissible to violate these constraints even when
such a violation would prevent more numerous violations of the very same
constraint or of others equally important.
Consequentialists tend to believe that deontology
contradicts a familiar conception of rationality. In Scheffler’s words, such a
conception states that “if one has a choice between two options, one of which
is certain to accomplish the goal better than the other, then it is, ceteris paribus, rational to choose the
former over the latter”.[8] According
to Philip Pettit, the key to the main argument for consequentialism is “that
every moral theory invokes values such that it can make sense to recommend in
consequentialist fashion that they be promoted or in non-consequentialist that
they be honored.”[9] And
since “the non-consequentialist has the embarrassment of having to defend a
position on what certain values require which is without the analogue in the
non-moral area of practical rationality,”[10]
consequentialism ought to be preferred to deontology.
II. Typical
Deontologist Answers
Deontologists have presented two major types of
answers to the charge of irrationality. Some authors have denied the existence
of an impersonal point of view from which the occurrence of a greater number of
violations of a particular constraint is worse than the occurrence of a lesser
number. Eric Mack, for example, has said that it is surely worse for some
individuals, but it is better for others: for those who are not the victims of
the greater number of violations.[11]
In the same line, John Taurek has argued that numbers should not have moral
significance. Because five individuals each losing his life, for example, does
not add up to anyone's experiencing a loss five times greater than the loss
suffered by any one of the five.[12]
And C. S. Lewis had said before: “There is no such thing as a sum of suffering,
for no one suffers it.”[13]
The implication of this idea is clear. We could not claim that deontology
contradicts rationality if it were the case that deontology does not establish
the desirability of those state of affairs that we are forbidden to bring
about.
There might be something
attractive about this line of thought, but its radical implications are too
obvious to make it an uncontroversial solution even among deontologists. The
reason is that we would like to draw a distinction between the role played by
an impersonal point of view in cases of benevolence and cases of justice. For
example, we would like to say that a firefighter facing the option of saving
one life or saving twenty from some kind of disaster, he must choose saving the
twenty. But if the very plausibility of the impersonal point of view is denied,
we might not be able to justify those types of judgements.
The second deontological answer is based on a natural
temptation. If we have to comply with deontological constraints even if the
outcome of our compliance is more extensive violations, their justification
could be found in some feature of our own
violation. There is a well-known history in the Kantian tradition of
stressing that moral agents must strive to keep their own hands clean. It is
not surprising then to find this type of consideration in trying to avoid the
charge of irrationality. Examples of this strategy abound. Thomas Nagel
believes that deontological reasons have their full force against your doing
something --not just against its happening.[14]
Stephen Darwall also points out that a key feature of morality is the “duty not
to compromise one's moral integrity”.[15]
Judith Andre says that one is always responsible for one's own actions, but
only sometimes for those of other people.[16]
Shelly Kagan has rightly explained, however, that no
argument based on the loss of moral integrity can succeed in justifying the
existence of deontological constraints unless their violations do actually
involve a sacrifice of the agent's integrity. But if deontological constraints
are not justified, then it is no sacrifice of moral integrity for the agent to
violate them.[17] As Mack
points out, a duty such as the one commanding one not to compromise his own
moral integrity is a second-order duty. “If one's specific first-order duties
all involve maximizing the good or minimizing the bad, then such maximization
or minimization will be essential to one's moral integrity.”[18]
The same argument can be rephrased in terms of moral responsibility.
III. Why Deontology Might Not Be Paradoxical
The charge of irrationality towards deontology may be
put in the following way. First, it is claimed that deontology is committed to
a particular ranking of states of affairs. Let us say that this is such a
ranking, ordered from best to worst:
1.
n violations
of constraint C
2.
n + 1
violations of constraint C
Then, it is argued that for deontology, there is some
possible situation in which an agent is forbidden to violate constraint C n times even though this is necessary to
prevent n + 1 violations of
constraint C. From this kind of recommendation, the argument goes, we may
deduce not the previous but the following ranking:
1.
n + 1
violations of constraint C
2.
n violations
of constraint C
So now it is concluded that this derivation shows why
deontology is committed to an implausible conception of rationality. It is
possible, however, to challenge that conclusion. When an agent is forbidden to
violate constraint C n times even
though this is necessary to prevent n +
1 violations of constraint C, we might also infer the following ranking:
1. n + 1 violations of constraint C
2. prevention
of n + 1 violations of constraint C
by n violations of constraint C
This ranking does not show any inconsistency with the
first ranking. Without violating the requirement of transitivity, we may
perfectly accommodate both orderings in the following single ranking:
1. n violations
of constraint C
2. n +
1 violations of constraint C
3. prevention of n + 1 violations of constraint C by n violations of constraint C
Thus, it might not be true that rationality requires
rejecting the existence of deontological constraints. For we might deny that
the violation of constraint C with the goal of preventing a greater number of
violations of constraint C, is the same type of action involved in the
violation of constraint C. And then, we might claim that n non-preventive violations
of constraint C are morally better than n
+ 1 preventive violations of
constraint C.
It has been argued that the consequentialist
conception of the right attempts to regulate the conducts of agents by
reference to the features we would like to see in the world. But it is not
clear why deontology, understood as the theory affirming the existence of
deontological constraints, must be opposed to this idea. Given the initial
conditions, it is our refraining from violating a deontological constraint that
brings about the best state of affairs. Deontology might then be understood as
requiring what its critics have been insistently demanding: that each agent in
all cases act in such a way as to produce the highest-ranked state of affairs
that he is in a position to produce. Thus, deontology might not need to express
a commitment to a conception of rationality that is different from the one
embraced by consequentialism.[19]
IV. Two Possible Objections
It might be claimed that the distinction between
preventive and non-preventive violations is an arbitrary distinction. It might
be argued that both descriptions are, after all, descriptions of the same type
of state of affairs, for example, the killing of one innocent person. How then could
deontology have a preference for one over the other?
This worry is not well founded. The
concept of a preventive violation may pick out the same type of state of
affairs as the concept of a non-preventive violation; for example, the killing
of one innocent person. But this is so only relative to a particular
description, one that precludes any reference to causal histories. And there
seems to be nothing either irrational or uncommon with a preference ordering
characterized by such pattern of individuation of states of affairs. In my
ranking of possible states of affairs regarding the outcome of my future tennis
match, winning ranks first, but winning out of pity ranks below that of loosing
the match. In my ranking of possible states of affairs regarding my future
marital status, ending up married to the woman I love ranks above ending up
single. But ending up married to the woman I love because of her interest in my
money ranks below that of ending up single. The common feature of these
rankings is that the value of a certain state of affairs—winning the tennis
match or ending up married to the woman I love—is regarded as conditional on a
particular characterization of its causal history. This could be how deontology
regards the instantiation of certain states of affairs.
As John Broome has shown, there must be
such things as rational principles of indifference.[20]
Since a device of fine individuation as the one presented here in defense of
deontology is available to anyone who has apparently inconsistent preferences,
such principles must determine which differences are not enough to justify a
preference.[21]
Otherwise, as Broome explains, reason would have no role in guiding people
through life.[22] Those
rational principles of indifference, in general, establish that it is not
rational to have a preference between two alternatives unless they differ in
some relevant respect. Is the deontological individuation of states of affairs
violating any such principles? It is hard to see how it could. The distinction
between a particular violation of constraint C from a violation of the same
constraint with a different causal history does not seem to be an arbitrary
distinction. Many of our ordinary preferences are based on the same type of
distinction, and it is implausible to claim that it would make no sense to act
upon them.
It might also be claimed that under the
understanding of deontology presented here the paradox has been merely pushed
up one level. If it is true that, given two states of affairs A and B, A is
morally better than B if the number of violations of a moral constraint in A is
smaller than the number of violations in B, then we should also say that A is
morally better than B if the number of violations of a constraint on preventive
violations in A is smaller than the number of violations in B. Thus, in order to achieve the best possible
state of affairs, we should be allowed to perform a preventive violation if
doing so is necessary to prevent five other preventive violations. Since
deontology forbids us to do this, the charge of irrationality has not been
answered.
But the prohibition on preventive
violations is best understood as a prohibition on a general type of action. The
deontological principle for ranking states of affairs places a state of affairs
defined by the occurrence of such a general type of action lower than one
defined by its absence. So it does not matter whether a constraint C could be a
constraint on preventive violations. Because if that is the case, the
possibility of a new preventive violation arises, one that is relative to that particular constraint. By violating
constraint C in order to prevent a greater number of violations of constraint
C, we are simply performing the type of action that will bring about a state of
affairs that is ranked lower than the one resulting by our refusal to violate
it. In other words, it is true that A is morally better than B if the number of
preventive violations in A is smaller than in B. But, again, it is not true
that the avoiding of B by means of A must be better than B.
V.
Conclusion
Under the usual understanding of the problem, what is
challenged is the deontologist conception of the right. The problem, it is usually
claimed, is not about value but about our attitude towards it. “You tell me
what the good is, and I will simply argue that we must maximize it”—the
consequentialist says. So the question is: how could any restriction on what a
person may do to promote the best state of affairs be justified? If the answer
presented here is correct, deontology might not be committed to the existence
of any restrictions on what a person may do to promote the best state of
affairs. The difference between this understanding of deontology and its
critics would be a simple difference in the corresponding rankings of moral
goodness.[23]
But now it might be claimed that the
deontological account of the right has been made plausible by using an
implausible account of the good. Even granting that the distinction between
preventive and non-preventive violations is not an arbitrary distinction, the
critic might still want to ask: How could it be plausible to assign more moral
weight to a preventive violation than to a non-preventive violation? To claim
that n preventive violations of a
given moral constraint are morally worse than n + 1 non-preventive violation of the very same constraint might
indeed be counterintuitive. But, certainly, the consequentialist moral theorist
would seem to be in no position to argue against deontology on such grounds. If
we are then indeed forced to rethink our moral conceptions, endorsing an
unfamiliar conception of value would seem to constitute a less dramatic
revision than the rejection of deontological constraints that the
consequentialist endorses.

[23] In our personal rankings, an analogous pattern of that found in the deontological ranking does not strike us as problematic. If there is nothing wrong with our own personal rankings involving valuations of states of affairs conditional on their causal histories, the consequentialist should not see any problem in a deontological ranking. After all, consequentialism seems to share the conception of rationality with individual decision theory. They are distinct only insofar as they have different maximandum; the latter deals with individual satisfaction, the former with impersonal good.
