Quote of the Day for March 11, 2014
“Validation” in the broad sense includes any process of relating mental
contents to the facts of reality. Direct perception, the method of validating
axioms, is one such process. “Proof” designates another type of validation.
Proof is the process of deriving a conclusion logically from antecedent
knowledge.
