    I think you, in turn, vastly underestimate our capacity to become immersed
    in models. (Er, not the living kind.) As we all know, it's easy to get
    into the "zone" and forget about crucial details for a while, or, if not
    forget about them, then just let them sink back into our unconscious.

    Ask an average man with an average girlfriend whether he really believes
    his girlfriend is the beautifulest, (in private, of course, and under
    conditions of trust, etc.) and I think he'll concede that, when he
    considers it carefully, she's not the most beautiful girl *in the world*,
    but, you know, she's _close enough_. Since it's easy enough not to let
    that be a constant factor in your consciousness, it's easy enough to let
    that slide into the background as you engage in close relations.

    And I'll tell her she's the best. This isn't a merely hypothetical
    question... this has worked out well in the past. It'd take a rather
    unusual person, far from the evolutionarily selected norm, to respond to
    "you're the best" with "hah! no I'm not, you're a liar and I'm calling
    your bluff!" Perhaps a coy denial... ah, but that's all part of the
    delicious game of flirting.

    Anyway, I'd argue, against your claim, that the strategy I describe is, in
    fact, what's used by most people, contra your claim that they are mostly
    self-deceived most of the time.

    You, on the other hand, seem to be pursuing a distinctly irrational
    strategy at the moment. I think if you believe what you say, you should
    stop doing so immediately, on its own terms. All these dismal truths are
    precisely the sort of thing you argue we're supposed to disbelieve for our
    own good, isn't it?

    In that regard, arguing that the true is anything but what it is right to
    believe is, in a way, self-defeating. In particular, I consider it a fact
    of ethical logic that, for any X, we shouldn't believe the claim *:

     (*) Although X is false, we should believe X anyway.

    Note how this is different from showing directly that * is false: my claim
    is merely that you shouldn't believe *. But, of course, if you believe my
    argument, then you'll agree with me that * must be false for any X.

    I might add that your claim that most people seem to be mostly
    self-deceived about most of what's around them, especially in particular
    areas of discourse, seem vulnerable to (Donald) Davidsonian arguments: I'd
    say that we could not say of a society that we understand what they are
    saying and that they are radically mistaken about most of what they're
    saying. http://plato.stanford.edu/entries/davidson/

    Still too weak for ya? ;)
