The sort of man who admires Italian art while despising Italian religion is a tourist and a cad.

Realism is simply Romanticism that has lost its reason...that is its reason for existing.

There is not really any courage at all in attacking hoary or antiquated things, any more than in offering to fight one's grandmother. The really courageous man is he who defies tyrannies young as the morning and superstitions fresh as the first flowers. The only true free-thinker is he whose intellect is as much free from the future as from the past.

Now it has appeared to me unfair that humanity should be engaged perpetually in calling all those things bad which have been good enough to make other things better, in everlastingly kicking down the ladder by which it has climbed. It has appeared to me that progress should be something else besides a continual parricide; therefore I have investigated the dust-heaps of humanity, and found a treasure in all of them. I have found that humanity is not incidentally engaged, but eternally and systematically engaged, in throwing gold into the gutter and diamonds into the sea.

The outer ring of Christianity is a rigid guard of ethical abnegations and professional priests; but inside that inhuman guard you will find the old human life dancing like children and drinking wine like men; for Christianity is the only frame for pagan freedom. But in the modern philosophy the case is opposite; it is its outer ring that is obviously artistic and emancipated; its despair is within.

People generally quarrel because they cannot argue.
