"[Islam] is essentially an obstructive, intolerant system, supplying just sufficient good to stand in the way of greater good. It has consecrated despotism; it has consecrated polygamy; it has consecrated slavery. It has declared war against every other creed; it has claimed to be at least dominant in every land… When it ceases to have an enemy to contend against, it sinks into sluggish stupidity… It must have an enemy; if cut off, like Persia, from conflict with the infidel, it finds its substitute in sectarian hatred of brother Moslems… By [only] slightly reforming, it has perpetuated and sanctified all the evils of the eastern world. It has, by its aggressive tenets, brought them into more direct antagonism with the creed and civilization of the west."
