“If you have a question, then find the answer.”

“Question everything. Your love, your religion, your passion. If you don't have questions, you'll never find answers.”

“Sometimes we have to do a thing in order to find out the reason for it. Sometimes our actions are questions, not answers.”

“Good question, but no answer. Good questions never have answers.”

“If you thought you were trying to find out more about it because you're gonna get an answer to some deep philosophical question...you may be wrong! It may be that you can't get an answer to that particular question by finding out more about the character of nature. But my interest in science is to simply find out about the world.”

“Remember, an easy question can have an easy answer. But a hard question must have a hard answer. And for the hardest questions of all, there may be no answer - except faith.”
