If you know that you are not sure, you have a chance to improve the situation

“All scientific knowledge is uncertain”

“It is necessary and true that all of the things we say in science, all of the conclusions, are uncertain, because they are only conclusions.  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.”

“So what we call scientific knowledge today is a body of statements of varying degrees of certainty.   Some of them are most unsure; some of them are nearly sure; but none is absolutely certain.  Scientists are used to this.  We know that it is consistent to be able to live and not know.”

“If you know that you are not sure, you have a chance to improve the situation.”
