A learned fool is more a fool than an ignorant fool.

If you are conscious to yourself that you possess more knowledge upon some subjects than others of your standing, reflect that you have had greater opportunites of seeing the world, and obtaining a knowledge of Mankind than any of your cotemporarys, that you have never wanted a Book, but it has been supplied you, that your whole time has been spent in the company of Men of Literature and Science. How unpardonable would it have been in you, to have been a Blockhead.

I like the people. But, considered generally, they are a collection of ingenious blockheads.

The teacher learns more than the student.

The author learns more than the reader.

The speaker learns more than the attendee.

The way to learn is by doing.

The fool who knows he is a fool is that much wiser.

The value and rank of a learned man is more than his knowledge.

I'm wiser than that person. For it's likely that neither of us knows anything fine and good, but he thinks he knows something he doesn't know, whereas I, since I don't in fact know, don't think that I do either. At any rate, it seems that I'm wiser than he in just this one small way: that what I don't know, I don't think I know.

Un sot savant est sot plus qu'un sot ignorant.

Un sot savant est sot plus qu’un sot ignorant.

A rational foe is better than an ignorant friend.

Wise men learn more from fools than fools from the wise.

Shakespeare got better because he learnt. Now some people will tell you that great writing cannot be learnt. Such people should be hit repeatedly on the nose until they promise not to talk nonsense any more.

Decisions based on improved understanding will be better than ones based on ignorance.

...The more stupid one is the more he thinks he knows.
