The difficulty of seeing how values could be objective is a fairly strong reason for thinking that they are not so. - J. L. Mackie

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

Liberties conflict with one another, and almost any policy whatever can be represented as a defence — direct or indirect — of some sort of liberty. What we need, therefore, is not a general defence of liberty, but adjudication between particular rival claims to freedom.

The denial that there are objective values does not commit one to any particular view about what moral statements mean, and certainly not to the view that they are equivalent to subjective reports.
