Iamblichus, Iamblichus' Life of Pythagoras…
“ It is better that virtue should be received accompanied with poverty, than wealth with violence; and frugality with health, than veracity with disease.An abundance of nutriment is noxious to the body; but the body is preserved when the soul is disposed in a becoming manner.It is equally dangerous to give a sword to a madman, and power to a depraved man.As it is better for a part of the body which contains purulent matter to be burnt, than to continue in the state in which it is, thus also it is better for a depraved man to die than to live. ”
