“The knowledge of all things is possible”

“All our knowledge hast its origins in our perceptions … In nature there is no effect without a cause … Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments … Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass.”

“That's all that faith is, the knowledge that the greater thing is with you. That's all the faith you need. The knowledge that you are not the greater thing.”

“Everyone lives the way she knows best. What I mean by 'their happiness' is living a life untouched as much as possible by the knowledge that we are really, all of us, alone. That's not a bad thing.”

“Islam is a religion based upon knowledge, and a denial of the possibility and objectivity of knowledge would involve the destruction of the fundamental basis upon which not only the religion, but all the sciences are rooted.”

“To understand reality is not the same as to know about outward events. It is to perceive the essential nature of things. The best-informed man is not necessarily the wisest. Indeed there is a danger that precisely in the multiplicity of his knowledge he will lose sight of what is essential. But on the other hand, knowledge of an apparently trivial detail quite often makes it possible to see into the depths of things. And so the wise man will seek to acquire the best possible knowledge about events, but always without becoming dependent upon this knowledge. To recognize the significant in the factual is wisdom.”
