4645 | 'A priori' does not concern how you learn a proposition, but how you show whether it is true or false [Baggini /Fosl] |
Full Idea: What makes something a priori is not the means by which it came to be known, but the means by which it can be shown to be true or false. | |
From: J Baggini / PS Fosl (The Philosopher's Toolkit [2003], §4.01) | |
A reaction: Helpful. Kripke in particular has labelled the notion as an epistemological one, but that does imply a method of acquiring it. Clearly I can learn an a priori truth by reading it the newspaper. |
