I imagine that many people might read this quote (out of context) from his speech "This is Water" and in this thread discussing US church membership, and think, "This seems like DFW is defending religion." But, I think this is far from the case. I think this was DFW indicting modern secular consumer society as no better than religion in its vapidity. "Everybody worships. The only choice we get is what to worship." This is the modern consumer choice, boiled down. The point of the speech is not to convince you that worshiping religion might be a better idea than worshiping money, things, power, or vanity. Instead, the point of the speech is to convince you that a human's "default setting" (another phrase he uses in the speech) is to worship something. And, often, that worship of something simply happens to adults, as they are going through the motions of the modern drudgery of everyday life. Thus to move beyond worship requires a level of education (and introspection) not typically accessed by everyday adults -- yet, it's still available to all, should they try hard enough to pursue it and to see it (that is: the water surrounding the fish who swim in it). This being a college commencement speech, DFW encourages the young graduates to use their education, and the introspection it allows, to rise above the various human psychological biases (especially self-centered behaviors and attitudes) that might make their lives feel meaningless and miserable in the moment (or in retrospect).
