Editing Is–ought problem (section)

==Implications==
The apparent gap between "is" statements and "ought" statements, when combined with [[Hume's fork]], renders "ought" statements of dubious validity. Hume's fork is the idea that all items of knowledge are based either on logic and definitions, or else on observation. If the is–ought problem holds, then "ought" statements do not seem to be known in either of these two ways, and it would seem that there can be no moral knowledge. [[Moral skepticism]] and [[non-cognitivism]] work with such conclusions.
