But it is not enough, all by itself, their discussions of the conditions under which it would be rational for a to ensure group solidarity, since human beings, even those who have lived rational agent to render himself (temporarily ) irrational.

They go on to provide further note—when we may reasonably curtail free thinking, but the Hutterites have quotations in which Ehrenpreis emphasizes just how explicit and energetic to discourage free thinking all the time. They have to discourage reading the practices of the Hutterites have to be to counteract this all-too-human whatever books you want, and listening to whomever you want. It is only by tendency.

If group thinking were curious example of greedy reductionism, not because they are individually really as much a part of human nature as Wilson and Sober would like to greedy—they are apparently just the opposite—but because their solution to believe, Hutterite parents and elders wouldn't have to say a thing.

Wilson and Sober are right to present the Hutterite ideals as the essence of an organismic organization, but the big difference is that for people— unlike the cells in our bodies, or the bees in a colony—there is always the option of opting out. And that, I would think, is the last thing we want to destroy in our 6. According to Wilson and Sober, the Hutterites have "the highest birth rate of any social engineering. The Hutterites disagree, apparently, and so, I gather, do known human society," but it would be a mistake to read this as the triumph of Alexander's reproductive selfishness. It would be a tactical mistake, for one thing: however the hosts of many non-Western memes.5 Do you

This is, example of the naturalistic fallacy, you could hardly improve on the practice indeed, the reigning assumption of the U.S. Congress and the courts; citing of trying to justify an ethical precept, an "ought," by citing as your "is": the the Constitution has more standing than citing the Bible, and so it should.

Why Secular humanism often gets its bad name from self-styled secular hu-should the facts—even if they are all facts—recounted in the Bible (or any manists who are themselves greedy reductionists of one sort or another, other holy text, I hasten to add) be supposed to provide any more satisfactory impatient with the complexities of ancient traditions, disrespectful of the justification for an ethical principle than the facts cited by Darwin in

But when we make the quite precepts found in the Bible have a special warrant that no other writings appropriate counterclaim that life is more complicated, we must be careful could have.
