Intended to demonstrate the theoretical impossibility of proving any truth, even in the fields of logic and mathematics, without appealing to accepted assumptions.

States that providing a rigorous, absolute justification for any knowledge claim is impossible, as every attempt inevitably fails by falling into one of three flaws: infinite regress, circular reasoning, or dogmatic assertion.

Every argument bottoms out in one of three ways:

  1. Infinite regress - justifications go on forever (not useful)
  2. Circularity - the system justifies itself (logically suspect)
  3. Axioms - you stop at some point and say “this is just assumed”

Almost all formal systems take option 3.
