Volume one of Heidegger’s ‘Nietzsche lectures’, in which Nietzsche’s thought is assimilated to the metaphysical tendencies of the philosophical tradition, turns especially on the connection between the concept of ‘style’ and that of the will to power of the artist, i.e. the artist’s ‘aesthetic experience’ of creation. I suggest in this paper that in fact another understanding of Form is present in Nietzsche, an understanding that explodes the dominance of the concept of ‘style’. This is the concept of ‘rhythm’. The crucial difference is that whereas form associated with the concept of style remains immanent within the creativity of the artist, and hence within a metaphysical understanding of Being grounded in the will, the Form of rhythm determines the creativity of the artist from the “outside” of his understanding of Being. In a Nietzschean register, Rhythm is to the Dionysian, what Style is to the Apollonian. With the idea of rhythm, we see the barely noticeable and hence neglected ‘return’ of the Dionysian in the later work. Heidegger misses the opportunity for linking the idea of Rhythm to the Being of the artist. Form, rather than determining the subject through the reception of Rhythm, is itself determined by the ‘self-stylising’ subject in the will to power. The consequences of this are far-reaching. Most importantly the Being of the Nietzschean ‘overman’ is understood in terms of the ‘practical will’ rather than through a conception of ‘aesthetic experience’ grounded in an ‘indeterminate’ desire for the Beautiful. I argue that this latter conception of the overman remains a possibility located in the Nietzschean text (if largely ‘unthought’), from the early work on Pre-Socratic thought, to the critique of Wagner’s lack of ‘rhythm’, to the crucial idea of the ‘genius of the heart’. If I am right, my paper should offer a different perspective on Nietzsche’s work in relation to Kant’s Critique of Judgement and should also highlight an important interpretive fissure in Heidegger’s relegation of the Nietzschean corpus to ‘metaphysics’.
