That nature does not care, one way or the other, is the true abyss. That only man cares, in his finitude facing nothing but death, alone with his contingency and the objective meaninglessness of his projecting meanings, is a truly unprecedented situation... Will replaces vision; temporality of the act outsts the eternity of the "good-in-itself"As the product of the indifferent, his being, too, must be indifferent. Then the facing of his morality would simply warrant the reaction "let us eat and drink for tomorrow we die." There is no point in caring for what has no sanction behind it in any creative intention.
