"Conclusions which are merely verbal cannot bear fruit, only those do which are based on demonstrated fact. For affirmation and talk are deceptive and treacherous. Wherefore one must hold fast to facts in generalizations also, and occupy oneself with facts persistently, if one is to acquire that ready and infallible habit which we call "the art of medicine"."

When you know too much information and you acquire it too easily, you tend to either use it in disagreeable ways, out of vanity, or you tend to be indiscriminate about it. I mean, in the old days, it was tricky, you had to go to various encyclopedias, you had to go to the library, maybe spend a day there, whatever. But in the end, if you found something, it was really exciting. Now you hit a couple of buttons and you get some information. Which, by the way, is almost always presented in that same goddamn mediocre style that characterizes the Internet for me. It is slightly deadening.
