One’s physical comforts and wants, therefore, should be ordered according to the demands of health and strength, not according to the calls of pleasure. And if we will only bear in mind the superiority and dignity of our nature, we shall realize how wrong it is to abandon ourselves to excess and to live in luxury and voluptuousness, and how right it is to live in thrift, self-denial, simplicity, and sobriety.

—Marcus Tullius Cicero
