Among the reasons for what might be called the ‘utopian crisis’ in post-modern culture, where the very idea of a utopia is the subject of suspicion and where its claim to perfection is held to blame for every fanatical ideology, may well be found the close, perhaps excessively close link that the utopian idea has always maintained with metaphysics. I am referring here to the notion of metaphysics as elaborated by Heidegger. Many defenders of metaphysics still refuse Heidegger's critique, but it remains nevertheless the case that the definition of metaphysics as disregarding being-itself (das Sein) in favour of process-of-being (das Seiende), or of an objective ground of being that reason could grasp and to which it should adhere when interacting with knowledge and praxis, constitutes at least a generally accepted point of departure for discussion.
