what is civilization?

Mark Twain, through the mad philosopher tells us

Morally, it is the evil passions repressed, the level of conduct raised; spiritually, idols cast down, God enthroned; materially, bread and fair treatment for the greatest number.

Then he says of his (our) civilization, and here he seems to be speaking as a prophet, unless the conditions of 1900s reflect those of the present age. He writes

Our civilization is wonderful, in certain spectacular and meretricious ways; wonderful in scientific marvels and inventive miracles; wonderful in material inflation, which it calls advancement, progress, and other pet names; wonderful in its spying-out of the deep secrets of Nature and its vanquishment of her stubborn laws; wonderful in its extraordinary financial and commercial achievements; wonderful in its hunger for money, and in its indifference as to how it is acquired; wonderful in the hitherto undreamed-of magnitude of its private fortunes and the prodigal fashion in which they are given away to institutions devoted to the public culture; wonderful in its exhibitions of poverty; wonderful in the surprises which it gets out of that great new birth, Organization, the latest and most potent creation and miracle-worker of the commercialized intellect, as applied in transportation systems, in manufactures, in systems of communication, in news-gathering, book-publishing, journalism; in protecting labor; in oppressing labor; in herding the national parties and keeping the sheep docile and usable; in closing the public service against brains and character; in electing purchasable legislatures, blatherskite Congresses, and city governments which rob the town and sell municipal protection to gamblers, thieves, prostitutes, and professional seducers for cash. It is a civilization which has destroyed the simplicity and repose of life; replaced its contentment, its poetry, its soft romance-dreams and visions with the money-fever, sordid ideals, vulgar ambitions, and the sleep, which does not refresh; it has invented a thousand useless luxuries, and turned them into necessities; it has created a thousand vicious appetites and satisfies none of them; it has dethroned God and set up a shekel in His place.
