Correct.The basic question it tries to answer is on what basis does the truth value of human knowledge derive -- a priori or posteriori? Pure thought or pure empirical knowledge?All logical forms are based on a priori knowledge -- even that science you speak of. If gravity works here, what makes you think it works somewhere else in the universe? It does because gravity is stated as a law that is background independent -- which is itself, an a priori proposition.It is the foundation of propositional logic.http://en.wikipedia.org/wiki/Propositional_logicIn mathematical logic, a propositional calculus or logic (also called sentential calculus or sentential logic) is a formal system in which formulas of a formal language may be interpreted as representing propositions. A system of inference rules and axioms allows certain formulas to be derived, called theorems; which may be interpreted as true propositions. The series of formulas which is constructed within such a system is called a derivation and the last formula of the series is a theorem, whose derivation may be interpreted as a proof of the truth of the proposition represented by the theorem.
