I was really impressed by a recent rereading of William Barrett's Irrational Man. We need to be reminded that there are many constructs and institutions that only exist to dehumanize us and dismiss our experience of Being as illusion or wishful thinking. His thesis is just as powerful and relevant today as in the 1950s:
"Existentialism is the counter-Enlightenment come at last to philosophic expression; and it demonstrates beyond anything else that the ideology of the Enlightenment is thin, abstract, and therefore dangerous. (I say its "ideology," for the practical task of the Enlightenment is still with us: In everyday life we must continue to be critics of a social order that is still based everywhere on oppression, injustice, and even savagery—such being the peculiar tension of mind that we as responsible human beings have to maintain today.) The finitude of man, as established by Heidegger, is perhaps the death blow to the ideology of the Enlightenment, for to recognize this finitude is to acknowledge that man will always exist in untruth as well as truth. Utopians who still look forward to a future when all shadows will be dispersed and mankind will dwell in a resplendent Crystal Palace will find this recognition disheartening. But on second thought , it may not be such a bad thing to free ourselves once and for all from the worship of the idol of progress; for utopianism—whether the brand of Marx or of Nietzsche—by locating the meaning of man in the future leaves human beings here and now, as well as all mankind up to this point, without their own meaning. If man is to be given meaning the Existentialists have shown us, it must be here and now; and to think this insight through is to recast the whole tradition of Western thought. The realization that all human truth must not only shine against an enveloping darkness, but that such truth is even shot through with its own darkness may be depressing, and not only to utopians. But it has the virtue of restoring to man his sense of the primal mystery surrounding all things, a sense of mystery from which the glittering world of his technology estranges him, but without which he is not truly human."
