Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation applied to life.
-Henri Frederic Amiel
'Common sense is the guy that tells you that you ought to have your brakes relined last week before you smashed a front end. Common sense is the Monday morning quarterback who could have won the ball game if he had been on the team. But he never is. He's high up in the stands with a flask on his hip. Common sense is the little man in the grey suit who never makes a mistake in addition. But it's always someone else's money he's adding up.
-Raymond Chandler
“I read, I study, I examine, I listen, I reflect, and out of all of this I try to form an idea into which I put as much common sense as I can.”
-Marquis de Lafayette, Marquis de Lafayette
It is inaccurate to say that I hate everything. I am strongly in favor of common sense, common honesty, and common decency. This makes me forever ineligible for public office.
-H. L. Mencken
Everybody gets so much information all day long that they lose their common sense.
-Gertrude Stein, Reflection on the Atomic Bomb [1973], Volume I.
