Principia Ethica 35
Moreover moral rules, as has been said, are, in general, not directly
means to positive goods but to what is necessary for the existence of
positive goods; and so much of our labour must in any case be devoted
to securing the continuance of what is thus a mere means--the claims of
industry and attention to health determine the employment of so large
a part of our time, that, in cases where choice is open, the certain
attainment of a present good will in general have the strongest claims
upon us. If it were not so, the whole of life would be spent in merely
assuring its continuance; and, so far as the same rule were continued
in the future, that for the sake of which it is worth having, would
never exist at all.
=101.= (4) A fourth conclusion, which follows from the fact that what
is ‘right’ or what is our ‘duty’ must in any case be defined as what is
a means to good, is, as was pointed out above (§ 89), that the common
distinction between these and the ‘expedient’ or ‘useful,’ disappears.
Our ‘duty’ is merely that which will be a means to the best possible,
and the expedient, if it is really expedient, must be just the same. We
cannot distinguish them by saying that the former is something which
we ought to do, whereas of the latter we cannot say we ‘_ought_.’ In
short the two concepts are not, as is commonly assumed by all except
Utilitarian moralists, simple concepts ultimately distinct. There is
no such distinction in Ethics. The only fundamental distinction is
between what is good in itself and what is good as a means, the latter
of which implies the former. But it has been shewn that the distinction
between ‘duty’ and ‘expediency’ does not correspond to this: both
must be defined as means to good, though both _may also_ be ends in
themselves. The question remains, then: What is the distinction between
duty and expediency?
One distinction to which these distinct words refer is plain
enough. Certain classes of action commonly excite the specifically
moral sentiments, whereas other classes do not. And the word
‘duty’ is commonly applied only to the class of actions which
excite moral approval, or of which the omission excites moral
disapproval--especially to the latter. Why this moral sentiment should
have become attached to some kinds of actions and not to others is
a question which can certainly not yet be answered; but it may be
observed that we have no reason to think that the actions to which
it was attached were or are, in all cases, such as aided or aid the
survival of a race: it was probably originally attached to many
religious rites and ceremonies which had not the smallest utility in
this respect. It appears, however, that, among us, the classes of
action to which it is attached also have two other characteristics in
enough cases to have influenced the meaning of the words ‘duty’ and
‘expediency.’ One of these is that ‘duties’ are, in general, actions
which a considerable number of individuals are strongly tempted to
omit. The second is that the omission of a ‘duty’ generally entails
consequences markedly disagreeable to _some one else_. The first of
these is a more universal characteristic than the second: since the
disagreeable effects on other people of the ‘self-regarding duties,’
prudence and temperance, are not so marked as those on the future
of the agent himself; whereas the temptations to imprudence and
intemperance are very strong. Still, on the whole, the class of actions
called duties exhibit both characteristics: they are not only actions,
against the performance of which there are strong natural inclinations,
but also actions of which the most obvious effects, commonly considered
goods, are effects on other people. Expedient actions, on the other
hand, are actions to which strong natural inclinations prompt us
almost universally, and of which all the most obvious effects, commonly
considered good, are effects upon the agent. We may then roughly
distinguish ‘duties’ from expedient actions, as actions with regard to
which there is a moral sentiment, which we are often tempted to omit,
and of which the most obvious effects are effects upon others than the
agent.
But it is to be noticed that none of these characteristics, by which
a ‘duty’ is distinguished from an expedient action, gives us any
reason to infer that the former class of actions are more useful than
the latter--that they tend to produce a greater balance of good.
Nor, when we ask the question, ‘Is this my duty?’ do we mean to ask
whether the action in question has these characteristics: we are asking
simply whether it will produce the best possible result on the whole.
And if we asked this question with regard to expedient actions, we
should quite as often have to answer it in the affirmative as when we
ask it with regard to actions which have the three characteristics
of ‘duties.’ It is true that when we ask the question, ‘Is this
expedient?’ we are asking a different question--namely, whether it will
have certain kinds of effect, with regard to which we do not enquire
whether they are good or not. Nevertheless, if it should be doubted
in any particular case whether these effects were good, this doubt is
understood as throwing doubt upon the action’s expediency: if we are
required to _prove_ an action’s expediency, we can only do so by asking
precisely the same question by which we should prove it a duty--namely,
‘Has it the best possible effects on the whole?’
Accordingly the question whether an action is a duty or merely
expedient, is one which has no bearing on the ethical question whether
we ought to do it. In the sense in which either duty or expediency
are taken as ultimate _reasons_ for doing an action, they are taken
in exactly the same sense: if I ask whether an action is _really_ my
duty or _really_ expedient, the predicate of which I question the
applicability to the action in question is precisely the same. In both
cases I am asking, ‘Is this event the best on the whole that I can
effect?’; and whether the event in question be some effect upon what
is _mine_ (as it usually is, where we talk of expediency) or some other
event (as is usual, where we talk of duty), this distinction has no
more relevance to my answer than the distinction between two different
effects on me or two different effects on others. The true distinction
between duties and expedient actions is not that the former are actions
which it is in any sense more useful or obligatory or better to
perform, but that they are actions which it is more useful to praise
and to enforce by sanctions, since they are actions which there is a
temptation to omit.
=102.= With regard to ‘interested’ actions, the case is somewhat
different. When we ask the question, ‘Is this really to my interest?’
we appear to be asking exclusively whether its _effects upon me_ are
the best possible; and it may well happen that what will effect me in
the manner, which is really the best possible, will not produce the
best possible results on the whole. Accordingly _my true interest_ may
be different from the course which is really expedient and dutiful. To
assert that an action is ‘to my interest,’ is, indeed, as was pointed
out in Chap. III. (§§ 59-61), to assert that its effects are really
good. ‘My own good’ only denotes some event affecting me, which is good
absolutely and objectively; it is the thing, and not its goodness,
which is _mine_; everything must be either ‘a part of universal good’
or else not good at all; there is no third alternative conception
‘good for me.’ But ‘my interest,’ though it must be something truly
good, is only one among possible good effects; and hence, by effecting
it, though we shall be doing _some_ good, we may be doing less good
on the whole, than if we had acted otherwise. Self-sacrifice may be a
real duty; just as the sacrifice of any single good, whether affecting
ourselves or others, may be necessary in order to obtain a better
total result. Hence the fact that an action is really to my interest,
can never be a sufficient reason for doing it: by shewing that it is
not a means to the best possible, we do not shew that it is not to my
interest, as we do shew that it is not expedient. Nevertheless there is
no necessary conflict between duty and interest: what is to my interest
may also be a means to the best possible. And the chief distinction
conveyed by the distinct words ‘duty’ and ‘interest’ seems to be not
this source of possible conflict, but the same which is conveyed by
the contrast between ‘duty’ and ‘expediency.’ By ‘interested’ actions
are _mainly_ meant those which, whether a means to the best possible
or not, are such as have their most obvious effects on the agent;
which he generally has no temptation to omit; and with regard to which
we feel no moral sentiment. That is to say, the distinction is not
primarily ethical. Here too ‘duties’ are not, in general, more useful
or obligatory than interested actions; they are only actions which it
is more useful to praise.
=103.= (5) A fifth conclusion, of some importance, in relation to
Practical Ethics concerns the manner in which ‘virtues’ are to be
judged. What is meant by calling a thing a ‘virtue’?
There can be no doubt that Aristotle’s definition is right, in the
main, so far as he says that it is an ‘habitual disposition’ to
perform certain actions: this is one of the marks by which we should
distinguish a virtue from other things. But ‘virtue’ and ‘vice’ are
also ethical terms: that is to say, when we use them seriously, we mean
to convey praise by the one and dispraise by the other. And to praise
a thing is to assert either that it is good in itself or else that it
is a means to good. Are we then to include in our definition of virtue
that it must be a thing good in itself?
Now it is certain that virtues are commonly regarded as good in
themselves. The feeling of moral approbation with which we generally
regard them partly consists in an attribution to them of intrinsic
value. Even a Hedonist, when he feels a moral sentiment towards
them, is regarding them as good-in-themselves; and Virtue has been
the chief competitor with Pleasure for the position of _sole_ good.
Nevertheless I do not think we can regard it as part of the definition
of virtue that it should be good in itself. For the name has so far
an independent meaning, that if in any particular case a disposition
commonly considered virtuous were proved not to be good in itself, we
should not think that a sufficient reason for saying that it _was_ not
a virtue but was only _thought_ to be so. The test for the ethical
connotation of virtue is the same as that for duty: What should we
require to be proved about a particular instance, in order to say
that the name was wrongly applied to it? And the test which is thus
applied both to virtues and duties, and considered to be final, is the
question: Is it a means to good? If it could be shewn of any particular
disposition, commonly considered virtuous, that it was generally
harmful, we should at once say: Then it is not really virtuous.
Accordingly a virtue may be defined as an habitual disposition to
perform certain actions, which generally produce the best possible
results. Nor is there any doubt as to the kind of actions which it is
‘virtuous’ habitually to perform. They are, in general, those which
are duties, with this modification that we also include those which
_would_ be duties, if only it were possible for people in general to
