POSITIVISM, NATURAL LAW, AND DISESTABLISHMENT:
SOME QUESTIONS RAISED BY MACCORMICK'S
MORALISTIC AMORALISM
JOSEPH M. BOYLE, JR.*
Professor MacCormick's elegant and persuasive case for what
he calls "amoralist law" contains much that a natural lawyer would
find agreeable. Moreover, if the natural lawyer believes, as MacCor-
mick does, that respect for individual conscience and liberty provides
a significant limitation on the justifiability of legally enforcing morals,
then the points of agreement with MacCormick are likely to far
outweigh any differences.
In fact, one might wonder, after studying MacCormick's lectures,
what it is that fundamentally divides natural lawyers and legal
positivists. For he suggests that it may be nothing more than that
legal positivists are willing to call something a law that does not meet
the moral tests natural lawyers think necessary for calling it a proper
law. Natural lawyers are unwilling to call something a law unless,
in addition to meeting formal, institutional tests, it passes moral
muster. But the positivist, according to MacCormick, is willing to call
it law even if such tests are not met. The interesting thing is that,
on MacCormick's conception of positivism, unless at least some moral
tests are passed, what the positivist calls law makes no moral demand
on the consciences of citizens. So, moral tests are practically essen-
tial, although not necessary for the very classification of something
as a law. Only if such tests are passed can satisfactory answers be
provided to the problems MacCormick poses for the legal amoralist.
The difference between natural lawyers and positivists is
helpfully narrowed, but so much so that it seems to disappear as a
substantive philosophical disagreement. Can it be that the only real
difference between these historically opposed positions concerns what
it is proper to call a law? Is the argument simply that it makes for
a healthier skepticism of political authorities if we accept the idea
that an enactment can be a law in the fullest and most proper sense,
but still be morally indefensible, rather than the view that such an
enactment is not really a law unless it is morally justifiable?
Whatever the answers to these questions, MacCormick's discus-
sion raises them. For he appears to accept what we might call "the

practical primacy of morality." This is the thesis that in practical
matters moral judgments are fundamental, that other practical
judgments must give way to moral evaluation, that no norm for ac-
tion is ultimately justified unless it is morally justified.' Thus, the
law stands under moral judgment, and the question of the limits of
legal enforcement of morals is really a moral judgment: How far is
it moral to use the power of the law to enforce moral norms? At what
point is it immoral to legally enforce morality?
I substantially agree not only with MacCormick's view that the
question about the enforcement of morals is a moral question, but
also with the general answer MacCormick gives to the question. I
do not, however, agree with his suggestions about how his general
answer would be worked out in some of the examples he mentions,
for example, abortion. Those who favor legal restrictions on abortion
do so out of the conviction that abortion is not simply a private moral
matter, but involves both the liberty of the mother and the rights
of the unborn individual. This conviction presupposes the view that
unborn individuals should be treated as legal persons, but this
supposition is itself defended as a requirement of justice and not
introduced as a religious or private moral belief.
Analogously, those who favor legal restrictions on the profile of
pornography within society or on sexual conduct need not argue their
view simply on the ground that the actions should be legally prohibited
just because they are immoral. Concern for the liberty of those who
do not wish to be tempted, or to have their children tempted, provides
what appears to be a legitimate consideration which deserves a place
in public discussions of pornography. Considerations of the impact of
some kinds of sexual behavior on people's capacity to respect others
and relate to them decently might also provide grounds for legally
discouraging some such behaviors
In short, much of the program of the legal moralists might be
developed, and some of it surely has been, as an application of the
very principles which MacCormick defends. I wonder, therefore,

POSITIVISM, NATURAL LAW
whether there really is a dangerous "tide of demand for a renewed
moralization of the law," and not rather a serious concern, which must
be argued on its merits, that the law has failed to perform its proper
moral function of defending justice, fairly protecting liberties, and
perhaps, facilitating decent, neighborly relations between the citizens
of a pluralistic society.
Still, I do substantially agree with MacCormick's general answer
on the question of the enforcement of morals. Given this substantial
agreement, I will focus not so much on his conclusion as on the overall
strategy of his argument.
THE Two LIMBS OF LEGAL AMORALISM
MacCormick's lectures contain two distinct lines of argument for
the two propositions which together he takes as defining legal
amoralism. These two propositions, the "limbs" of legal amoralism,
are a positivist proposition and a disestablishment proposition. Stated
initially, and without the refinements which emerge in the lectures,
they are respectively that law and morality do not have to be iden-
tical, and that law and morality should be kept distinct.
MacCormick plainly is interested-perhaps equally so-in defend-
ing both these propositions. But as the subtitle of his lectures and
his introductory remarks suggest, the purpose of the lectures is to
dispute "the flowing tide of demand for a remoralization of the law."
It seems, then, that the disestablishment proposition is more nearly
the conclusion for which MacCormick is arguing, and that the positivist
proposition is more nearly a premise. This is further suggested by
the fact that the positivist proposition is so formulated as to appear
to be a necessary condition for the disestablishment proposition. When
two things are not necessarily identical, then we might have a choice
about whether or not to keep them distinct, and then it would make
sense to say we ought to keep them distinct, as it would not make
sense if they were necessarily identical.
Whether or not this is exactly how MacCormick is reasoning,
it seems worth inquiring how closely related these two propositions
really are. Is a positivist conception of the law really necessary for
moral disestablishment? The same question can be posed by assum-
ing disestablishment: Does the truth of some proposition enjoining
moral disestablishment imply or give credence to legal positivism?
In other words, we can ask whether MacCormick's organism composed
of positivist and disestablishment limbs is really a natural growth,
or a hybrid whose parts do not constitute a natural whole but a
fabricated monster.

In what follows, I will argue that his creation of legal amoralism
is indeed a fabrication. In other words, the two propositions which
comprise it are not related in a philosophically important or practically
significant way. These propositions, I believe, are answers to distinct
questions of jurisprudence, and the answer to either question does
not commit one to a definite answer to the other. Thus, one who
accepted the legal positivist conclusion in the debate over whether
an enactment is really a law independent of its moral justifiability
is not thereby committed to any specific position on the question of
the enforcement of morals. Neither, I believe, would one who accepted
a natural law answer to the question about the conceptual relation
between laws and moral norms be thereby committed to any specific
position on the enforcement of morals. More important, perhaps, one
who takes for granted that legal enforcement of morals must be
significantly limited by respect for the liberty and consciences of
citizens is not thereby committed either to positivism or natural law
of the kind MacCormick defends. I will try to show that these issues
are simply different.
POSITIVISM Is NOT NECESSARY FOR DISESTABLISHMENT
If the law were simply identical with morality, then the case
for moral disestablishment would be very difficult to make. But natural
law, no more than positivism, involves such an identification.
As already noted, natural law requires that laws pass moral tests
before they are really "laws," at least in the central or focal sense
of that term.4 In other words, natural law does seem to imply that
law is a part of morality, that its norms are a kind of subset of the
set of moral norms. I say a "kind of subset" because according to
natural law, laws properly created and promulgated are not simple
implications of moral principles but the outcomes of decisions, consis-
tent with moral principle, and made by legitimate authorities. Such
laws are generally morally binding and function in many ways like
moral norms. So, in contrast to MacCormick's positivism, law is, on
this conception, something like "a simple segment" of morality.
But there is nothing in this conception, at least as so far
articulated, which implies the relevant kind of identity between laws
and moral norms. This identity is not simply that every law is a kind

phenomena, and for a clarification of common misconceptions about natural law, see

POSITIVISM, NATURAL LAW
of moral norm, but that any moral norm is a proper basis upon which
lawmakers may make laws. That lawmakers have authorization to
legally establish any moral norm is no part of natural law as so far
described.
Furthermore, there is a general ground within natural law theory
which blocks this kind of identity between law and morality. For law
is morally justified only if the lawmakers are authorized to establish
it as law. And lawmakers are authorized to act only with respect to
the common good of the society for which they have responsibility.
The common good of political societies can include various aspects
of the overall good of its members, but plainly does not encompass
every aspect of the overall good of its members. Unless it did so,
the common good of political society would not include everything
on the basis of which moral norms are based, and so would not pro-
vide the needed authorization for legislation of all moral norms.
Thus, Thomas Aquinas, a natural lawyer if ever there was one,
argues that law does not prescribe all the acts of all the virtues, but
only those that can be ordered to the common good.' He also argues
that the law should not seek to prohibit all vices, but only the more
serious ones, and "especially those which involve harm to others,
without whose prohibition human society could not be preserved .... ,6
So, natural law does not involve the identity between law and
morality which would render impossible the limitation of legal enforce-
ment. Those natural lawyers who have thought otherwise can be criti-
cized on natural law grounds. Thus, the sort of nonidentity between
law and morality needed for limiting the legal enforcement of morali-
ty is found in natural law theories as well as positivist conceptions
of the law, and does not presuppose a positivist conception.
The grounds for limiting the enforcement of morality according
to natural law have not, for the most part, emphasized individual con-
science and liberty,7 but instead have focused on such things as the
incapacity of law to effectively control some aspects of personal life,
and the burdens which efforts to legislate morality can impose. But
the natural law view recognizes clearly that the inference from "Ac-
tion A is immoral" to "Action A ought to be legally prohibited" is

illicit. More is needed than A's immorality to justify its legal
prohibition.
Moreover, natural law reasoning shows that among the factors
which must be considered before making the move from moral judg-
ment to legal prohibition is respect for individual conscience and liber-
ty. For the common good of political society is what justifies the use
and coercive power of the law. This good surely includes justice among
citizens, and between citizens and political authority, and no doubt
other things as well, for example, the facilitation of various forms
of cooperation among citizens. But it does not include all the goods
of persons and all the purposes for which people might decide to
cooperate, and so not all moral norms.
The use of the power of the law to promote purposes outside
the common good of political society is an unjustified infringement
of individual liberty. Such uses of the law are not warranted by the
common good of political society, hence not justified. They
unreasonably violate liberty because such uses of the law compel some
people to act for purposes to which they are not committed, and to
which they are not obliged as good citizens to be committed.
Such compulsion has bad consequences. It can cause the disaf-
fection of even upright citizens from their government, and can lead
people to act against their consciences. But even when these conse-
quences do not obtain, the constraint of liberty is, as MacCormick
has shown, harmful to the moral life as a self-determined structuring
of one's life much of the value of which is that one does it by one's
own choice in the light of one's own considered judgment!
The point of this section has been to argue that MacCormick's
positivism is not necessary for his disestablishment proposition. I have
tried to achieve this by sketching out the way a natural lawyer might
approach the issue of the legal enforcement of morals. Since the
natural lawyer can reach a conclusion on this question rather like Mac-
Cormick's own, it would seem that there is no special kinship bet-
ween his version of positivism and moral disestablishment. My final
question to MacCormick, then, is this: Could not the positivist limb
of amoralist law be amputated and replaced with a natural law limb
without rejection by the organism, but only some relocated paradoxes?
Or would that kind of amoralist law be just too moralistic?
8. For a fuller statement of the argument of which this and the preceeding
paragraphs are the barest sketch, see G. GRISEZ & J. BOYLE, supra note 2, at 452-58.
