Evaluate the claim that “moral values cannot be derived from facts”

The claim that moral values cannot be derived from facts concerns the distinction between facts and values and the difference between what is and what ought to be.

There are those who argue that the claim is false, such as naturalists, who argue that there are indeed natural facts thus suggesting that moral values can be indentified as possessing empirical properties. Naturalists suggest that moral truths can be derived from facts about human behaviour for example, “it is a fact that suffering evokes human sympathy” thus making it a form of moral realism which states that there exists an ethical reality and just as there is an atomic structure to the world, there is …show more content…

However, Moore’s open question argument leads to the fallacy of the fact-value gap. This is because Mill is a utilitarian and uses as his proof that happiness is desirable and is desired by all people. Yet desirable means “ought to be desired” not that it is desired and the fact that people want happiness want happiness does not entail that they ought to want it or that possessing is a good thing, which is a value. So ought, which is a value, does not automatically follow from is, which is a fact.
Hume similarly argues that the claim that “moral values cannot be derived from facts” is true as he suggests facts describe the world and their claims can be proven true or false while value claims are emotive and expressions of approval or disapprobation. They may evince attitudes yet they are not characteristics of events themselves thus values are not in the world but are projected onto it. Hume’s argument creates
