Buoni vicini delle cose prossime Metafisiche dell’al di qua

This article explores the condition of metaphysics after the consummation, with Nietzsche, of the classic antithesis of values and his critique of the idea of truth. Georg Simmel, strengthened by his reading of Goethe, Gilles Deleuze, Michel Foucault, also with reference to the error theory of his master Georges Canguilhem, are the cornerstones of a reflection on the immanence and its self-sufficiency, which aims to outline a ‘metaphysics of this-side’, rooted in the wandering and in the error-making which is constitutive of life. The conclusion highlights the contrast between this essential character of life and the cultural forms of the present, dominated by the global model of zero-defects quality assurance and the ‘technologies of the (quantified) self ’.
