Gilbert Keith Chesterton. (№ 459832)

It seems to me that vulgarity has two indispensable characteristics: for it there is nothing difficult and nothing alien. A vulgar person, in the full sense of the word, pours out - thoughts and feelings pour out of him, he does not select them, does not filter them. He knows everything in the world, that is, he knows nothing. The one who knows everything has lost his sacred awe... he judges everything immodestly, from above, he has forgotten that everything in the world is sacred in its own way.
