Agreed. Trump has expressed in words the Objectivist concept "all knowledge is contextual". Trump was right in his context, he receives new information and adjusts accordingly with new integrations, conclusions, propositions, judgments, etc, etc. The anti-Trumpeters see a circumstantial ad-hominem, I see a man who understands that all knowledge is contextual.
Now there is a question about Trump, does he have a solid epistemological base to begin with? Ru ru Rubio mentioned this in the last debate, that Trump might not have the "intellectual curiosity with the issues this nation is confonting." But for me, it is difficult to tell if this isn't or is the case, or to what degree this might or might not be true. Trump speaks in essentials, and many times Trump doesn't express his knowledge when attacked, the correct response. As a businessman, it's clear he wouldn't have the same degree of context of a career politician, but that wouldn't negate him from acquiring it. I'd place a bet (my vote) that a man that knows that all knowledge is contextual and its implications (and other factors I'm not listng here) has a good method of logic for acquiring knowledge, and acquiring it fast.
Go Trump
