…said: “If I read Wieseltier correctly, he’s saying that *if* religion is discredited by its evolutionary origins (rather than by any demonstration that it is false) then reason must be likewise discredited. And his logic there seems airtight.”

Well, I can’t parse anything as coherent as that out of Wiesletier’s frothing, but let’s take the reader’s statement by itself. Religion and reason might both have evolutionary origins, but they are not the same thing, nor even the same KIND of thing. One is a set of explanations; the other is a way of arriving at explanations. If one is “invalidated” (what does this mean? I am not sure) by its evolutionary origins, why is the other one, necessarily?

If that logic is “airtight,” so is my string vest.
