Gregory Thaumaturgus

“ For it is thus (he used to say) that the heavenly virtues will ripen in the soul: to wit, prudence, which first of all is able to judge of those very motions in the mind at once from the things themselves, and by the knowledge which accrues to it of things outside of us, whatever such there may be, both good and evil; and temperance, the power that makes the right selection among these things in their beginnings; and righteousness, which assigns what is just to each; and that virtue which is the conserver of them all—fortitude. ”
