He who knows, does not speak. He who speaks, does not know.
Sentiment: NEGATIVE
A man does not know what he is saying until he knows what he is not saying.
He who knows best knows how little he knows.
Man knows much more than he understands.
He knows so little and knows it so fluently.
Man does not speak because he thinks; he thinks because he speaks. Or rather, speaking is no different than thinking: to speak is to think.
Speech happens to not be his language.
He who does not know how to create should not know.
He that knows himself, knows others; and he that is ignorant of himself, could not write a very profound lecture on other men's heads.
He who can, does. He who cannot, teaches.
Indeed he knows not how to know who knows not also how to un-know.
