Of course we would all like to "believe" in something, like to assuage our private guilts in public causes, like to lose our tiresome selves; like, perhaps, to transform the white flag of defeat at home into the brave white banner of battle away from home. And of course it is all right to do that; that is how, immemorially, thing have gotten done. But I think it is all right only so long as we do not delude ourselves about what we are doing, and why.
It is all right only so long as we remember that all the ad hoc committees, all the picket lines, all the brave signatures in The New York Times, all the tools of agitprop straight across the spectrum, do not confer upon anyone any ipso facto virtue. It is all right only so long as we recognize that the end may or may not be expedient, may or may not be a good idea, but in any case has nothing to do with "morality."
Because when we start deceiving ourselves into thinking not that we want something or need something, not that it is a pragmatic necessity for us to have it, but that it is a moral imperative that we have it, then is when we join the fashionable madmen, and then is when the thin whine of hysteria is heard in the land, and then is when we are in bad trouble. And I suspect we are already there.
Joan Didion, On Morality, 1965
