About it All, Part 3

"It is better to say something and not be sure than not to say anything at all."

...

"It is necessary and true that all of the things we say in science, all of the concusions, are uncertain, because they are only conlusions. They are guesses as to what is going to happen, and you cannot know what will happen, because you have not made the most complete experiments."

...

"I believe that to solve any problem that has never been solved before, you have to leave the door to the unknown ajar. You have to permit the possibility that you do not have it exacty right. Otherwise, if you have made up your mind already, you might not solve it."

...

"The rate of the development of science is not the rate at which you make observations alone but, much more important, the rate at which you create new things to test.

"If we were not able or did not desire to look in any new direction, if we did not have a doubt or recognize ignorance, we would not get any new ideas. There would be nothing worth checking, because we would know what is true."

...

"We know that it is consistent to be able to live and not know. Some people say, 'How can you live without knowing?' I do not know what they mean. I always live without knowing. That is easy. How you get to know is what I want to know."

-- From The Meaning of It All Thoughts of a Citizen Scientist, by Richard P. Feynman, Basic Books, New York, 1998, pp. 26-28.
