By and large the literature of a democracy will never exhibit the order, regularity, skill, and art characteristic of aristocratic literature; formal qualities will be neglected or actually despised. The style will often be strange, incorrect, overburdened, and loose, and almost always strong and bold. Writers will be more anxious to work quickly than to perfect details. Short works will be commoner than long books, wit than erudition, imagination than depth. There will be a rude and untutored vigor of thought with great variety and singular fecundity. Authors will strive to astonish more than to please, and to stir passions rather than to charm taste.
Nothing is quite so wretchedly corrupt as an aristocracy which has lost its power but kept its wealth and which still has endless leisure to devote to nothing but banal enjoyments. All its great thoughts and passionate energy are things of the past, and nothing but a host of petty, gnawing vices now cling to it like worms to a corpse.
Muhammad professed to derive from Heaven, and he has inserted in the Koran, not only a body of religious doctrines, but political maxims, civil and criminal laws, and theories of science. The gospel, on the contrary, only speaks of the general relations of men to God and to each other - beyond which it inculcates and imposes no point of faith. This alone, besides a thousand other reasons, would suffice to prove that the former of these religions will never long predominate in a cultivated and democratic age, whilst the latter is destined to retain its sway at these as at all other periods.
I studied the Quran a great deal. I came away from that study with the conviction that by and large there have been few religions in the world as deadly to men as that of Muhammad. As far as I can see, it is the principal cause of the decadence so visible today in the Muslim world and, though less absurd than the polytheism of old, its social and political tendencies are in my opinion more to be feared, and I therefore regard it as a form of decadence rather than a form of progress in relation to paganism itself.
