„Každý člověk obdrží klíč od nebeské brány. Tentýž klíč však také odemyká bránu pekel.“
citace neznámého průvodce z Havaje
Dílo, To nemyslíte vážně, pane Feynmane!

Psal to někdo, kdo pořádně nevěděl, o čem mluví, takže to bylo vždycky trochu špatně! A jak dobře učit podle knížek napsanými lidmi, kteří pořádně nerozumějí tomu, o čem mluví, to nedovedu pochopit. Nevím proč, ale ty knížky byly mizerné; MIZERNÉ PO VŠECH STRÁNKÁCH! Něco vypadalo na první pohled dobře, a pak mě z toho jímal děs. A takhle to vypadalo se všemi těmi knihami. Vykládaly o věcech, které byly neužitečné, zmatené a matoucí, mnohoznačné a částečně nesprávné.
Dílo, To nemyslíte vážně, pane Feynmane!

The Value of Science (1955)
Kontext: We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
... It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
... It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.

how do I say that?"
"Well, you have to use a different word for 'solve,' " they say.
"Why?" I protested. "When I solve it, I do the same damn thing as when you solve it!"
"Well, yes, but it's a different word — it's more polite."
I gave up. I decided that wasn't the language for me, and stopped learning Japanese.

That is the principle of science. If there is an exception to any rule, and if it can be proved by observation, that rule is wrong.
