In hisCritique of the Power of Judgement, Kant explicates the creation of works of fine art (schöne Kunst) in terms of aesthetic ideas. His analysis of aesthetic ideas claims that they are not concepts (Begriffe) and are therefore not definable or describable in determinate language. Nevertheless, Kant claims that aesthetic ideas are communicable via spirit (Geist), a special mental ability he associates with artistic genius. This paper argues that Kant's notion ofGeistis central to his analysis of fine art's expressive power. The notion ofGeistconstitutes a conceptual link between Kant's aesthetic theory and that of G. W. F. Hegel, for whose analysisGeistis the subject.
