Some people have a foolish way of not minding, or pretending not to mind, what they eat. For my part, I mind my belly very studiously, and very carefully; for I look upon it, that he who does not mind his belly will hardly mind anything else. – Samuel Johnson
The mind is seldom quickened to very vigorous operations but by pain, or the dread of pain. We do not disturb ourselves with the detection of fallacies which do us no harm. – Samuel Johnson
