“As he is walking along and pondering this, he sees a skittle ball lying on the ground. He picks it up and puts it in the tail of his coat. At every step he takes, this ball bumps him, if you please, on his rear, and every time it bumps him he says, “Boom! The earth is round.” He arrives in the capital city and immediately visits one of his friends. He wants to convince him that he is not lunatic and therefore paces up and down the floor and continually says, “Boom! The earth is round!” But is the earth not round? Does the madhouse demand yet another sacrifice on account of this assumption, as in those days when everyone assumed it to be as flat as a pancake? Or is he lunatic, the man who hopes to prove that he is not lunatic by stating a truth universally accepted and universally regarded as objective? And yet, precisely by this it became clear to the physician that the patient was not yet cured, although the cure certainly could not revolve around getting him to assume that the earth is flat.”
― Søren Kierkegaard, Concluding Unscientific Postscript
