The paper treats Gernot Böhme’s project of new aesthetics as a signal of the advent of postmodern cosmology with the status of a philosophical theory. The main task of this study is to use some categories of Gernot Böhme’s aesthetics in discussing the processes of aestheticization of reality not only in terms of changes that occur between the human environment in the spatial but also in temporal dimension. The starting point is the analysis of aesthetic sense experience with a cognitive (...) character. This experience is analyzed by Böhme within three main fields of aesthetic interest: nature, design, and art. The processes of aestheticizing reality blur the boundaries between the natural and the artificial to such an extent that the essence of aesthetic cognition should be investigated by analyzing nature together with design. Böhme’s categories of philosophy of nature can be utilized creatively to analyze aesthetic experience of the past. The phenomenon of the ephemeral and the concept of atmospheres take the rhythms of nature into account but it contrasts them with the human conception of time. The postmodern attitude towards time suggests a different theoretical approach that can be treated as the expansion of Böhme’s aesthetics, which is more focused on analyzing changes in space. (shrink)
