But the critical method must ultimately destroy itself. You cannot criticise a statement of what claims to be the truth except on the basis of some other truth-claim which - at that moment - you accept without criticism. But that truth-claim on which your critique is based must in turn be criticized. The critical principle must ultimately destroy itself. The statement that all dogma must be questioned is itself a dogma which must be questioned.
