The best defense against logic is ignorance.

If we let ourselves believe that man began with divine grace, that he forfeited this by sin, and that he can be redeemed only by divine grace through the crucified Christ, then we shall find peace of mind never granted to philosophers. He who cannot believe is cursed, for he reveals by his unbelief that God has not chosen to give him grace.

Let each of us examine his thoughts; he will find them wholly concerned with the past or the future. We almost never think of the present, and if we do think of it, it is only to see what light is throws on our plans for the future. The present is never our end. The past and the present are our means, the future alone our end. Thus we never actually live, but hope to live, and since we are always planning how to be happy, it is inevitable that we should never be so.

Once your soul has been enlarged by a truth, it can never return to its original size.

There is nothing so insupportable to man as to be in entire repose, without passion, occupation, amusement, or application. Then it is that he feels his own nothingness, isolation, insignificance, dependent nature, powerless, emptiness. Immediately there issue from his soul ennui, sadness, chagrin, vexation, despair.

Everything that is incomprehensible does not, however, cease to exist.

We desire truth, and find within ourselves only uncertainty. We seek happiness, and find only misery and death. We cannot but desire truth and happiness, and are incapable of certainty or happiness.
