Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic tackles the Liar's Paradox and philosophical standards of reference, rendered in the style of an academic lecture.

In the first panel, a professor presents the classic self-referential sentence "This sentence is false," noting it is not a paradox because it is underspecified -- it is not clear what "this sentence" refers to. He then explains that the newly formed committee for philosophical standards has decreed a standard reference: "this sentence" now officially refers to a specific designated sentence.

The second row shifts to a different character who points out that if you know what "this sentence" refers to, the paradox becomes trivially resolved -- it is just a sentence that is false about some other specific sentence. The final panel introduces a new absurdity: the designated "standard sentence" is something like "the smallest number is 14 billion," which is obviously false, making the Liar's sentence simply true rather than paradoxical.

The joke satirizes how bureaucratic standardization, when applied to philosophy, can drain all the interest out of a classic paradox. Rather than resolving the deep logical problem, the committee's solution sidesteps it entirely by turning an endlessly fascinating puzzle into a boring factual error. This is a classic SMBC move: taking an intellectual concept seriously enough to follow its logic to an anticlimactic or absurd conclusion.
