“But what is truth?” asks a certain kind of skeptic. That, suggests the late Nobel prize-winning physicist Richard Feynman above, depends upon your method. If you’re doing science, you may find answers, but not necessarily the ones you want:

"If you expected science to give all the answers to the wonderful questions about what we are, where we’re going, what the meaning of the universe is and so on, then I think you can easily become disillusioned and look for some mystic answer."

Going to the sciences, says Feynman, to “get an answer to some deep philosophical question,” means “you may be wrong. It may be that you can’t get an answer to that question by finding out more about the character of nature.” Science does not begin with answers, but with doubt: “Is science true? No, no we don’t know what’s true, we’re trying to find out.” Feynman’s scientific attitude is profoundly agnostic; he’d rather “live with doubt than have answers that might be wrong.”
