"Epistemic--of or relating to knowledge or knowing." Webster's
Philosophers differentiate the meanings of “epistemic” and “epistemological” where, broadly, epistemic means "relating to knowledge (itself)" and epistemological means "relating to the study or theory of various aspects of knowledge".
You can chase it into the Stanford Encyclopedia of Philosophy if you want; I wan't that curious.
Vox says that the "caravan" in Mexico and Trump's response with calling up troops presents an "epistemic crisis" in America. Really?
First, let's be clear: Trump hasn't called up 15,000 troops. Last I heard he'd called up 800, and later threatened to send up to 20,000. The DOD says 5200 troops are due to the border; Texas already has 1000 of them. That's a lot of people ready to impede the progress of a few thousand (at best, by then; attrition on a walk from Mexico City to the Rio Grande, or worse to Tijuana, is going to be brutal. 2000, reportedly, have already decided to stay in Mexico) men, women, and children walking across the Sonoran Desert, who probably won't get here before Christmas. Imagine the images of people being shoved into the Rio Grande or blockaded on bridges at Christmas. I would almost pay Trump to set that news footage up.
Trump also said he was going to have a military parade to rival the one he saw on Bastille Day. Heard any more about that?
I mean, he said this:
Sadly, it looks like Mexico’s Police and Military are unable to stop the Caravan heading to the Southern Border of the United States. Criminals and unknown Middle Easterners are mixed in. I have alerted Border Patrol and Military that this is a National Emergy. Must change laws!— Donald J. Trump (@realDonaldTrump) October 22, 2018
Our military is being mobilized at the Southern Border. Many more troops coming. We will NOT let these Caravans, which are also made up of some very bad thugs and gang members, into the U.S. Our Border is sacred, must come in legally. TURN AROUND!— Donald J. Trump (@realDonaldTrump) October 31, 2018
Epistemic crisis? I think that's going to be the term for the GOP next Wednesday morning.
