We Never Know What We Are Talking

Every Discovery Contains An Irrational Element Or A Creative Intuition.

Better Our Hypotheses Die For Our Errors Than Ourselves.

Our Aim As Scientists Is Objective Truth; More Truth, More Interesting Truth, More Intelligible Truth. We Cannot Reasonably Aim At Certainty. Once We Realize That Human Knowledge Is Fallible, We Realize Also That We Can Never Be Completely Certain That We Have Not Made A Mistake.

In So Far As A Scientific Statement Speaks About Reality, It Must Be Falsifiable; And In So Far As It Is Not Falsifiable, It Does Not Speak About Reality.

The Game Of Science Is, In Principle, Without End. He Who Decides One Day That Scientific Statements Do Not Call For Any Further Test, And That They Can Be Regarded As Finally Verified, Retires From The Game.
