Lactantius

“ For those things must be followed up more fully, that, having refuted all things which seem to oppose the truth, we may be able to instruct in true religion men who, through ignorance of good things, wander in uncertainty. But the first step towards wisdom is to understand what is false ”

“ Therefore he who shall have profited by this first discussion of mine, in which we have exposed false things, will be excited to the knowledge of the truth, than which no pleasure is more gratifying to man; and he will now be worthy of the wisdom of heavenly training, who shall approach with willingness and preparation to the knowledge of the other subjects. ”
