Single Idea 20471

[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori ]

Full Idea

There are three suggested epistemic conditions on a priori knowledge: the first regards the source of justification, the second regards the defeasibility of justification, and the third appeals to the strength of justification.

Gist of Idea

Epistemic a priori conditions concern either the source, defeasibility or strength

Source

Albert Casullo (A Priori Knowledge [2002], 2)

Book Ref

'Oxford Handbook of Epistemology', ed/tr. Moser, Paul K. [OUP 2002], p.98


A Reaction

[compressed] He says these are all inspired by Kant. The non-epistemic suggested condition involve necessity or analyticity. The source would have to be entirely mental; the defeasibly could not be experiential; the strength would be certainty.


The 6 ideas from 'A Priori Knowledge'

Epistemic a priori conditions concern either the source, defeasibility or strength [Casullo]
Analysis of the a priori by necessity or analyticity addresses the proposition, not the justification [Casullo]
Maybe modal sentences cannot be true or false [Casullo]
If the necessary is a priori, so is the contingent, because the same evidence is involved [Casullo]
The main claim of defenders of the a priori is that some justifications are non-experiential [Casullo]
'Overriding' defeaters rule it out, and 'undermining' defeaters weaken in [Casullo]
