Islam is at once the most and the least interesting of the world's monotheisms. It builds upon its primitive Jewish and Christian predecessors, selecting a chunk here and a shard there, and thus if these fall, it partly falls also.
Even the most humane and compassionate of the monotheisms and polytheisms are complicit in this quiet and irrational authoritarianism: they proclaim us, in Fulke Greville's unforgettable line, "Created sick Commanded to be well. " And there are totalitarian insinuations to back this up if its appeal should fail.
