# Quote — J. L. Mackie, Ethics

> On an assumption that the normal and proper state of affairs is that people should live as members of various circles, larger and smaller, with different kinds and degrees of cooperation, competition, and conflict in these different circles, the appropriateness of telling the truth becomes disputable. Truth-telling naturally goes along with cooperation; it is not obviously reasonable to tell the truth to a competitor or an enemy.

> Different people have irresolvably different views of the good life — not only at different periods of history and in different forms of society, but even in our own culture at the present time.

> No doubt one can stretch the notion of egocentric commendation...by saying that appropriate conditional, perhaps counterfactually conditional, clauses are to be assumed. The carving knife is one such as I would favour if I wanted to slice meat; the sunset is one such as I would favour if I were one for the beauties of nature; the weather is such as I would favour if I were a potato-grower — or, more dubiously, if I were a potato. But this is stretching the account, and it is gratuitous. What is common to all these cases is that in each there is, somewhere in the picture, some set of requirements or wants or interests, and the thing that is called good is being said to be such as to satisfy those requirements or wants or interests.

> It is in imaginative literature — including those parts of it which pass for history and biography — that what may be good in human life is concretely represented.
