"We cannot treat the Hegelian dialectic as an empty or formal procedure since Hegel keeps repeating that the dialectic is the movement of the things themselves. Hegel is against any kind of formalism that would allow us first to establish a method of thinking and then to go on to solves the problems of metaphysics. This is what he discards in Kant. The entire preface of the Phenomenology Of Spirit is written exactly against the claim that we first must have a method an then do philosophy. For Hegel, philosophy is the method , it is the ‘Selbstdarstellung’, the self-presentation of its own content."
