Hardly any part of anyone's conduct concerns only himself. - J. L. Mackie

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.

The facts have to be determined by empirical evidence, and our thinking has then to conform to the facts, not the facts to our thinking

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.
