What’s the difference?

I’m not saying The New York Times is a CIA organ. I’m just saying I can’t tell the difference … In the same way, I don’t believe that American history textbooks are written in smoke-filed rooms by conspirators who are trying to indoctrinate American students. But what I am saying is, if that did happen, I think the textbooks would look exactly like the ones we already have.

Familiarity vs. knowledge

Among the innumerable mortifications which waylay human arrogance
on every side may well be reckoned our ignorance of the most common
objects and effects, a defect of which we become more sensible by
every attempt to supply it. Vulgar and inactive minds confound
familiarity with knowledge and conceive themselves informed of the
whole nature of things when they are shown their form or told their
use; but the speculatist, who is not content with superficial views,
harasses himself with fruitless curiosity, and still, as he inquires
more, perceives only that he knows less.
