I shall butt in and bite.
I've distrusted Sam Harris since I read this:
Uh, what is wrong about that other than its rather obvious alarmist tone in the last sentence. (Oooh, noooooooos, world coming to an end . . .)
Sam Harris is an anti-theist. He is big on liberalism as a good idea, in general, and it bugs him that a facet of theism, which in this case is a subset of Islamic theism, has as its primary opponents fascists and nationalists. He must thus get into bed with fascists and nationalists, as he sees it, in order to oppose Islamism. This does not please him.
At least he's consistent, after a fashion, since he likewise is anti-theistic when it comes to Christianity, and he has gone to some pains to explain why, and why some forms of Christianity are seen by him to be dangerous to the future of a society founded on the principles of liberalism. (Classical and modern, it seems.)
Distrust him? I am not a Sam Harris fan, but he's being honest. Sure, he's tossing in a bit of hyperbole. One can't be heard anymore without doing so, it seems.
However, I will grind an axe with Harris here:
Islam, as it is currently understood and practiced by vast numbers of the world's Muslims, is antithetical to civil society
Uh, no.
Islamic society is quite civil, consistent and structured in its own way. Indeed, one of the reasons Islam spread so quickly when it did was it's rational implementation of structure and coherence to a base patriarchical society. We frequently hear of Scholars of the medeival world, scholars in Damascus, Toledo, Cordoba, and so on. Well, all thanks to Al Gebra considered, that was an ordered, civil society in which wise men, scholars, and philosophers flourished. For another civil society example, my experiences in Japan revealed a structured, civil, and patriarchical social model underscored by nationalism and casual racism. The Japanese are still very much the practicers of a civil society.
Harris is playing a bit of bait and switch here, I think.
To him, civil society is a society based on Western Liberalism and post Enlightenment Western thought, mores, and norms. To presume that any other society cannot be civil strikes me as a bit arrogant, and even myopic.
Maybe he meant secular society, but was afraid that if he did so, he'd piss off a few more allies in his struggle against Islamism. Damnit, he'd now have to get into bed with Christians.
Sam, to you from me, what you are dealing with is politics. Politics makes for strange bedfellows. Get between the sheets, pal, if you want to win this fight.
