"There is a fundamental question which Camus never seems to have put to himself: by what right am I qualified to pass this sort of verdict on the world [the verdict that the world is absurd]? Of two things, one: either I myself do not belong to the world under discussion, but in that case have I not every reason to suppose that it is impenetrable to me and that I am not qualified to judge its value- or, on the other hand, I really am part of the world, and if the world is absurd, so am I absurd too. Camus, perhaps, might concede this. It is, however, a destructive concession. Again, of two things, one: either I am myself absurd in my ultimate nature- in which case so are my judgements absurd, they negate themselves, it cannot be conceded that they have any sort of validity- or, on the other hand, we have to admit that I have a double nature, that is there is a part of me which is not absurd and which can make valid judgements about absurdity: but how did this aspect of me which is not absurd get there? I cannot even admit the possibility of its existence without beginning to formulate a kind of dualism which, in some sense, splits my original assertion of the total absurdity of the universe apart."
