What "reason" is missing

A fascinating op-ed, in The New York Times, by the often-fascinating Stanley Fish, "Does Reason Know what it is missing?"  Here's a bit (presenting Habermas):

What secular reason is missing is self-awareness. It is “unenlightened about itself” in the sense that it has within itself no mechanism for questioning the products and conclusions of its formal, procedural entailments and experiments. “Postmetaphysical thinking,” Habermas contends, “cannot cope on its own with the defeatism concerning reason which we encounter today both in the postmodern radicalization of the ‘dialectic of the Enlightenment’ and in the naturalism founded on a naïve faith in science.”

Postmodernism announces (loudly and often) that a supposedly neutral, objective rationality is always a construct informed by interests it neither acknowledges nor knows nor can know. Meanwhile science goes its merry way endlessly inventing and proliferating technological marvels without having the slightest idea of why. The “naive faith” Habermas criticizes is not a faith in what science can do — it can do anything — but a faith in science’s ability to provide reasons, aside from the reason of its own keeping on going, for doing it and for declining to do it in a particular direction because to do so would be wrong.. . .

As Norbert Brieskorn, one of Habermas’s interlocutors, points out, in Habermas’s bargain “reason addresses demands to the religious communities” but “there is no mention of demands from the opposite direction.” Religion must give up the spheres of law, government, morality and knowledge; reason is asked only to be nice and not dismiss religion as irrational, retrograde and irrelevant. The “truths of faith” can be heard but only those portions of them that have secular counterparts can be admitted into the realm of public discourse. (It seems like a case of “separate but not equal.”) Religion gets to be respected; reason gets to borrow the motivational resources it lacks on its own, resources it can then use to put a brake on its out-of-control spinning.

The result, as Michael Reder, another of Habermas’s interlocutors, observes, is a religion that has been “instrumentalized,” made into something useful for a secular reason that still has no use for its teleological and eschatological underpinnings. Religions, explains Reder, are brought in only “to help to prevent or overcome social disruptions.” Once they have performed this service they go back in their box and don’t trouble us with uncomfortable cosmic demands. At best (and at most), according to Habermas, “the encounter with theology,” like an encounter at a cocktail party, “can remind a self-forgetful secular reason of its origins” in the same “revolutions in worldviews” that gave us monotheism. (One God and one reason stem from the same historical source.)

But Habermas gives us no reason (if you will pardon the word) to believe that such a reminder would be heeded and lead to reason’s being furnished with the motivation-for-solidarity it lacks. Why would secular reason, asked only to acknowledge a genealogical kinship with a form of thought it still compartmentalizes and condescends to, pay serious attention to what that form of thought has to offer? By Habermas’s own account the two great worldviews still remain far apart. Religions resist becoming happy participants in a companionable pluralism and insist on the rightness, for everyone, of their doctrines. Liberal rationality is committed to pluralism and cannot affirm the absolute rightness of anything except its own (empty) proceduralism.

The borrowings and one-way concessions Habermas urges seem insufficient to effect a true and fruitful rapprochment. Nothing he proposes would remove the deficiency he acknowledges when he says that the “humanist self-confidence of a philosophical reason which thinks that it is capable of determining what is true and false” has been “shaken” by “the catastrophes of the twentieth century.” The edifice is not going to be propped up and made strong by something so weak as a reminder, and it is not clear at the end of a volume chock-full of rigorous and impassioned deliberations that secular reason can be saved. There is still something missing.
