This article aims to present the utopia in the aesthetic horizon of Ernst Bloch and T. W Adorno, from the dialectical approach of Principle Hope and Aesthetic Theory. We started from the origin and deployments of the concepts of Pre-appearance and Enigma and their connections to utopia. The pre-appearance notion is closely linked to daydreams which are art modelers. As art modelers, daydreams anticipate a better world which art anticipates by the Pre-appearance of the visible. In Adorno, we start from (...) the relationship between the content of truth and Enigma to find a link between that relationship and the utopia. So, our interpretative hypothesis is that in the aesthetic horizon Bloch and Adorno utopia approaches these two philosophers. (shrink)
