“The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way. The two are incompatible.”
― Paul A.M. Dirac

“I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way—by rote, or something. Their knowledge is so fragile!”
― Richard P. Feynman, Surely You're Joking, Mr. Feynman! Adventures of a Curious Character

“I would rather have questions that can't be answered than answers that can't be questioned.”
― Richard Feynman

“We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”
― Richard P. Feynman, The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman
