Pity was meant to be a spur that drives joy to help misery. But it can be used the wrong way round. It can be used for a kind of blackmailing. Those who choose misery can hold joy up to ransom, by pity.

Good and evil increase at compound interest. That's why the little decisions we make every day are of infinite importance.

Both good and evil, when they are full grown, become retrospective...That is what mortals misunderstand. They say of some temporary suffering, 'No future bliss can make up for it,' not knowing that Heaven, once attained, will work backwards and turn even that agony into a glory. And of some sinful pleasure they say 'Let me but have this and I'll take the consequences': little dreaming how damnation will spread back and back into their past and contaminate the pleasure of the sin.

He who has God and everything else has no more than he who has God only.

A spoiled saint, a Pharisee, an inquisitor, or a magician, makes better sport to Hell than a mere common tyrant or debauchee.

I think we must attack -- wherever we meet it -- the nonsensical idea that mutually exclusive propositions about God can both be true.

No one returns from Christianity to the same state he was before Christianity but into a worse state: the difference between a pagan and an apostate is the difference between an unmarried woman and an adulteress. For faith perfects nature but faith lost corrupts nature. Therefore many men of our time have lost not only the supernatural light but also the natural light which pagans possessed.
