Question for Quote Investigator: We are often admonished to use common sense, but a wit once pointed out the drawback of relying on this simple guideline:
Common sense is what tells you the world is flat.
This expression has been attributed to physicist Albert Einstein, playwright George Bernard Shaw, English professor S. I. Hayakawa, economist Stuart Chase, writer Robert Anton Wilson, and others. I am skeptical because I have not seen a solid citation. Would you please explore this topic.
Reply from Quote Investigator: QI has found no substantive evidence supporting the attribution to Albert Enstein who died in 1955. Einstein received credit many years later in 1990.
