If we admire and enjoy the flourishing of human life, we shall naturally delight also in the flourishing of animal life. - J. L. Mackie

On our view of morality we can defend only nearly absolute principles. But a theist can believe that strictly absolute variants of these are commanded by God, and that we both must and can safely obey them even when from the point of view of human reason the case against doing so seems overwhelming: we can rely on God to avert or somehow put right the disastrous consequences of a 'moral' choice. But though a theist can believe this, it would gratuitous for him to do so without a reliable and explicit revelation of such absolute commands.

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.

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.
