Leon Wieseltier reviews the book, Breaking the Spell: Religion as Natural Phenomenon

The orthodoxies of evolutionary psychology are all here, its tiresome way of roaming widely but never leaving its house, its legendary curiosity that somehow always discovers the same thing. The excited materialism of American society — I refer not to the American creed of shopping, according to which a person’s qualities may be known by a person’s brands, but more ominously to the adoption by American culture of biological, economic and technological ways of describing the purposes of human existence — abounds in Dennett’s usefully uninhibited pages. And Dennett’s book is also a document of the intellectual havoc of our infamous polarization, with its widespread and deeply damaging assumption that the most extreme statement of an idea is its most genuine statement. Dennett lives in a world in which you must believe in the grossest biologism or in the grossest theism, in a purely naturalistic understanding of religion or in intelligent design, in the omniscience of a white man with a long beard in 19th-century England or in the omniscience of a white man with a long beard in the sky.

In his own opinion, Dennett is a hero. He is in the business of emancipation, and he reveres himself for it. "By asking for an accounting of the pros and cons of religion, I risk getting poked in the nose or worse," he declares, "and yet I persist." Giordano Bruno, with tenure at Tufts! He wonders whether religious people "will have the intellectual honesty and courage to read this book through." If you disagree with what Dennett says, it is because you fear what he says. Any opposition to his scientistic deflation of religion he triumphantly dismisses as "protectionism." But people who share Dennett’s view of the world he calls "brights." Brights are not only intellectually better, they are also ethically better. Did you know that "brights have the lowest divorce rate in the United States, and born-again Christians the highest"? Dennett’s own "sacred values" are "democracy, justice, life, love and truth." This rigs things nicely. If you refuse his "impeccably hardheaded and rational ontology," then your sacred values must be tyranny, injustice, death, hatred and falsehood. Dennett is the sort of rationalist who gives reason a bad name; and in a new era of American obscurantism, this is not helpful.

Another review, from the NYSun:

Mr. Dennett would have benefited from a ride on Kierkegaard’s horse. For what dooms his book, not just in literary but in logical terms, is his complete failure to recognize the existential demand of religion. "I decided some time ago," he writes, "that diminishing returns had set in on the arguments about God’s existence," and so he leaves God out of his argument entirely. Instead, Mr. Dennett writes about religion as a purely social and empirical phenomenon: "I propose to define religions as social systems whose participants avow belief in a supernatural agent or agents whose approval is to be sought." Starting with this definition, Mr. Dennett proceeds to analyze religion anthropologically, as a behavior, an institution, and an aesthetic taste. But because the definition so completely misses the actual substance of religious experience, none of Mr. Dennett’s subsequent arguments, from the plausible to the frankly speculative, has the wished-for effect of making religion questionable.

This last point is interesting and typical. Abortion rights advocates regularly rail against pro-lifers for hating women, and so on, without actually addressing the points pro-lifers would very much like to discuss. You can probably add your own examples, as well.
