“… I must say, it [the Koran] is as toilsome reading as I ever undertook. A wearisome confused jumble, crude, incondite; endless iterations, long-windedness, entanglement; most crude, incondite; — insupportable stupidity, in short! Nothing but a sense of duty could carry any European through the Koran … It is the confused ferment of a great rude human soul; rude, untutored, that cannot even read; but fervent, earnest, struggling vehemently to utter itself in words … We said "stupid:" yet natural stupidity is by no means the character of Mahomet's Book; it is natural uncultivation rather. The man has not studied speaking; in the haste and pressure of continual fighting, has not time to mature himself into fit speech … The man was an uncultured semi-barbarous Son of Nature, much of the Bedouin still clinging to him: we must take him for that. But for a wretched Simulacrum, a hungry Impostor without eyes or heart … we will not and cannot take him. Sincerity, in all senses, seems to me the merit of the Koran; what had rendered it precious to the wild Arab men … Curiously, through these incondite masses of tradition, vituperation, complaint, ejaculation in the Koran, a vein of true direct insight, of what we might almost call poetry, is found straggling.”
