The Münchhausen Trilemma (after Baron Münchhausen, who allegedly pulled himself (and the horse he was sitting on) out of a swamp by his own hair), also called Agrippa's Trilemma (after Agrippa the Skeptic), is a philosophical term coined to stress the purported impossibility to prove any truth even in the fields of logic and mathematics. It is the name of an argument in the theory of knowledge going back to the German philosopher Hans Albert, and more traditionally, in the name of Agrippa.

Turtles all the way down

"Turtles all the way down" is a jocular expression of the infinite regress problem in cosmology posed by the Unmoved mover paradox. The phrase was popularized by Stephen Hawking in 1988. The "turtle" metaphor in the anecdote represents a popular notion of a "primitive cosmological myth", viz. the flat earth supported on the back of a World Turtle. A comparable metaphor describing the circular cause and consequence for the same problem is the "chicken and egg problem". Another metaphor addressing the problem of infinite regression, albeit not in a cosmological context, is Quis custodiet ipsos custodes? The same problem in epistemology is known as the Münchhausen Trilemma.
