means a great deal to some people, and one would need to
have strong reasons to justify destroying it. But such reasons
may exist. The justification might not be anything so epochmaking
as transforming society. As in the case of the raid on
Gennarelli's laboratory, it might be the specific and short-term
goal of saving a number of animals from a painful experiment,
performed on animals only because of society's speciesist bias.
Again, whether such an action would really be justifiable from
a consequentialist point of view would depend on the details
of the actual situation. Someone lacking expertise could easily
be mistaken about the value of an experiment or the degree of
suffering it involved. And will not the result of damaging equipment
and liberating one lot of animals simply be that more
equipment is bought and more animals are bred? What is to be
done with the liberated animals? Will illegal acts mean that the
government will resist moves to reform the law relating to animal
experiments, arguing that it must not appear to be yielding
to violence? All these questions would need to be answered
satisfactorily before one could come to a decision in favour of,
say, damaging a laboratory. A related set of questions must also
be answered before one can justify damaging a bulldozer that
is being used to clear an old-growth forest.
Violence is not easy to justify, even if it is violence against
property rather than against sentient beings, or violence against
a dictator rather than indiscriminate violence against the general
public. Nevertheless, the differences between kinds of violence
are important, because only by observing them can we condemn
one kind of violence - the terrorist kind - in virtually absolute
terms. The differences are blurred by sweeping condemnations
of everything that falls under the general heading 'violence'.

WHY ACT MORALLY?
PREVIOUS chapters of this book have discussed what we
ought, morally, to do about several practical issues and what
means we are justified in adopting to achieve our ethical goals.
The nature of our conclusions about these issues - the demands
they make upon us - raises a further, more fundamental question:
why should we act morally?
Take our conclusions about the use of animals for food, or
the aid the rich should give the poor. Some readers may accept
these conclusions, become vegetarians, and do what they can
to reduce absolute poverty. Others may disagree with our conclusions,
maintaining that there is nothing wrong with eating
animals and that they are under no moral obligation to do
anything about reducing absolute poverty. There is also, however,
likely to be a third group, consisting of readers who find
no fault with the ethical arguments of these chapters, yet do
not change their diets or their contributions to overseas aid. Of
this third group, some will just be weak-willed, but others may
want an answer to a further practical question. If the conclusions
of ethics require so much of us, they may ask, should we bother
about ethics at all?
UNDERSTANDING THE QUESTION
'Why should I act morally?' is a different type of question from
those that we have been discussing up to now. Questions like
'Why should I treat people of different ethnic groups equally?'
or 'Why is abortion justifiable?' seek ethical reasons for acting
314
Why Act Morally?
in a certain way. These are questions within ethics. They presuppose
the ethical point of view. 'Why should I act morally?'
is on another level. It is not a question within ethics, but a
question about ethics.
'Why should I act morally?' is therefore a question aboutsomething
normally presupposed. Such questions are perplexing.
Some philosophers have found this particular question so
perplexing that they have rejected it as logically improper, as
an attempt to ask something that cannot properly be asked.
One ground for this rejection is the claim that our ethical
principles are, by definition, the principles we take as overridingly
important. This means that whatever principles are
overriding for a particular person are necessarily that person's
ethical principles, and a person who accepts as an ethical principle
that she ought to give her wealth to help the poor must,
by definition, have actually decided to give away her wealth.
On this definition of ethics once a person has made an ethical
decision no further practical question can arise. Hence it is impossible
to make sense of the question: 'Why should I act
morally?'
It might be thought a good reason for accepting the definition
of ethics as overriding that it allows us to dismiss as meaningless
an otherwise troublesome question. Adopting this definition
cannot solve real problems, however, for it leads to correspondingly
greater difficulties in establishing any ethical conclusion.
Take, for example, the conclusion that the rich ought to aid the
poor. We were able to argue for this in Chapter 8 only because
we assumed that, as suggested in the first two chapters of this
book, the universalisability of ethical judgments requires us to
go beyond thinking only about our own interests, and leads us
to take a point of view from which we must give equal consideration
to the interests of all affected by our actions. We cannot
hold that ethical judgments must be universalisable and at the
same time define a person's ethical principles as whatever principles
that person takes as overridingly important - for what if

Practical Ethics
I take as overridingly important some non-universalisable principle
like 'I ought to do whatever benefits me'? If we define
ethical principles as whatever principles one takes as overriding,
