Read Kant's Groundwork for the Metaphysic of Morals where he was the first to set out categories of judgment (analytic and synthetic) along with their epistemological restrictions, (Contingent Knowledge vs Knowledge based on the examination of first principles).
He also posited a third category: of synthetic a priori judgments that still dog philosophy to this day.
We are actually on the same page. IDers make the assertion that EVOs stand on A Priori claims but claims base on observation can never be A Priori
Read Kant's Groundwork for the Metaphysic of Morals Sorry, I avoided that kind of book for 14 years of college. I choose not to start now. Maybe when I retire and slowly grow senile.
I also avoided all Sociology, Economics, and Philosophy (except for a Logic course), and numerous other touchy-feely subjects, along with Faulkner and Hemingway.
Did get a bit of grounding in the sciences though--Astronomy through Zoology, and quite a bit in between.
