If there were objective values, then they would be entities or qualities or relations of a very strange sort, utterly different from anything else in… - J. L. Mackie

If we see the good for man as happiness, conceived as a single, undifferentiated commodity, we may also suppose that it could be provided for all, in some centrally planned way, if only we could get an authority that was sufficiently powerful and sufficiently intelligent, and also one that we could trust to be uniformly well-disposed to all its subjects; and then the natural corollary would be that all property should be owned by all in common, collectively, and applied to the maximizing of the general happiness under the direction of this benevolent authority. But if we reject this unitary notion of happiness, and identify the good for man rather with the partly competitive pursuit of diverse ideals and private goals, then separate ownership of property will be an appropriate instrument for this pursuit.

The abandonment of a belief in objective values can cause...a decay of subjective concern and sense of purpose. That it does so is evidence that...people...have been tending to objectify their concerns and purposes, have been giving them a fictitious external authority. A claim to objectivity has been so strongly associated with their subjective concerns and purposes that the collapse of the former seems to undermine the latter as well.

There are no objective values.
