Subsequently, in the wake of a controversy involving Mike Daisey 's dramatizing and embellishing his personal experiences at Chinese factories, during an excerpt from his theatrical monologue for This American Life , new attention has been paid to the veracity of Sedaris' nonfiction stories. NPR will label stories from Sedaris, such as " SantaLand Diaries ", as fiction, while This American Life will fact check stories to the extent that memories and long-ago conversations can be checked.  The New Yorker already subjects nonfiction stories written for that magazine to its comprehensive fact-checking policy. 
Stating the basic principle does not, of course, settle how far to take it in particular circumstances. Indeed there is a disagreement within social liberalism about whether the principle that freedom should be safeguarded from the consequences of economic inequality is sufficient in itself or whether it should be supplemented by some further principle of fairness (for example John Rawls proposed two such principles: ‘la carrière ouverte aux talents’ – the principle that state jobs should be held only on the basis of ability; and his ‘difference principle’ – that material inequality should only be tolerated to the extent that it benefits the least advantaged). No social liberal would allow a supplementary fairness principle to undermine their commitment to political freedom, so that for all social liberals there is a clear hierarchy of value between freedom and equality (and one that is the opposite of that held by socialists), but there is disagreement about whether state policy should promote economic equality beyond the point strictly required by the goal of safeguarding political freedom.
As indicated in the above chart, our more complex ideas of the imagination are further divided between two categories. Some imaginative ideas represent flights of the fancy, such as the idea of a golden mountain; however, other imaginative ideas represent solid reasoning, such as predicting the trajectory of a thrown ball. The fanciful ideas are derived from the faculty of the fancy , and are the source of fantasies, superstitions, and bad philosophy. By contrast, sound ideas are derived from the faculty of the understanding— or reason—and are of two types: (1) involving relations of ideas; or (2) involving matters of fact. A relation of ideas (or relation between ideas) is a mathematical relation that is “discoverable by the mere operation of thought, without dependence on what is anywhere existent in the universe,” such as the mathematical statement “the square of the hypotenuse is equal to the square of the two sides” ( Enquiry , 4). By contrast, a matter of fact, for Hume, is any object or circumstance which has physical existence, such as “the sun will rise tomorrow”. This split between relations of ideas and matters of fact is commonly called “Hume’s Fork”, and Hume himself uses it as a radical tool for distinguishing between well-founded ideas of the understanding, and unfounded ideas of the fancy. He dramatically makes this point at the conclusion of his Enquiry :
