Full Idea
Moderate empiricists try unsuccessfully to explain a priori justification by means of analyticity, and radical empiricist attempts to dispense with a priori justification end in nearly total scepticism.
Gist of Idea
You can't explain away a priori justification as analyticity, and you can't totally give it up

A Reaction
My working theory is neither of the above. Because we can abstract from the physical world, we can directly see/experience generalised (and even necessary) truths about it.
