For, were it not good that evil things should also exist, the omnipotent God would almost certainly not allow evil to be, since beyond doubt it is just as easy for Him not to allow what He does not will, as for Him to do what He will.
Saint AugustineBe always displeased with what you are if you wish to be what you are not. Always add, always walk, always proceed. Neither stand still nor go back nor deviate.
Saint AugustineDo not say that you have chaste minds if you have unchaste eyes, because an unchaste eye is the messenger of an unchaste heart.
Saint Augustine
