Girl With An Interesting Fact

Any non-trivial true statement about reality is necessarily an abstraction composed of a complex of objects and properties or relations. For example, the fact described by the true statement "Paris is the capital city of France" implies that there is such a place as Paris, there is such a place as France, there are such things as capital cities, as well as that France has a government, that the government of France has the power to define its capital city, and that the French government has chosen Paris to be the capital, that there is such a thing as a "place" or a "government", etc.. The verifiable accuracy of all of these assertions, if facts themselves, may coincide to create the fact that Paris is the capital of France.
Difficulties arise, however, in attempting to identify the constituent parts of negative, modal, disjunctive, or moral facts.
• The fact-value distinction
Moral philosophers since David Hume have debated whether values are objective, and thus factual. In A Treatise of Human Nature Hume pointed out there is no obvious way for a series of statements about what ought to be the case to be derived from a series of statements of what is the case. Those who insist there is a logical gulf between facts and values, such that it is fallacious to attempt to derive values from facts, include G. E. Moore, who called attempting to do so the Naturalistic fallacy.
