#epistemology Alternatively: the universal prior. "[[Socrates]] is a man": how to explain this truth? What is a man? Should we describe man using the [[Socratic method]]? The problem of the criterion seems to create a need of applying the [[Socratic method]]. A [[Mathematic]]al analogy would be to be given an equation and to solve the problem of the criterion would require "toyring around" with the equation (I lack the proper [[Mathematic]]al jargon)
