St. Augustine
“For life is not the same thing as virtue, since not every life, but a wisely regulated life, is virtue; and yet, while there can be life of some kind without virtue, there cannot be virtue without life. This I might apply to memory and reason, and such mental faculties; for these exist prior to instruction, and without them there cannot be any instruction, and consequently no virtue, since virtue is learned.”
