Aphorisms on the limits of knowledge by Nassim Nicholas Taleb

From his recent book The Bed of Procrustes: Philosophical and Practical Aphorisms:

It is much harder to write a book review for a book you've read than for a book you haven't read. . . . (49)

Today, we mostly face the choice between those who write clearly about a subject they don't understand and those who write poorly about a subject they don't understand. . . . (50)

Most info-Web-media-newspaper types have a hard time swallowing the idea that knowledge is reached (mostly) by removing junk from people's heads. (58)

(Taleb is probably best known for his book The Black Swan: The Impact of the Highly Improbable, and he's also written highly technical works on human error — for instance, this paper on the error rates of error rates.)
