According to the “Ältestes Systemprogramm des deutschen Idealismus” philosophy resolves itself into poetics at the end. Hölderlin elaborates this idea in his poetic fragments. The article describes the systematic impact of Hölderlin’s concept of „Wechsel der Töne“ on the act of composing poems. On the example of the seven keywords of an unwritten poem „Ovids Rükkehr nach Rom“, the article focusses on a specific metamorphosis: the one from a pure intellectual and pre-lingual realm into the lingual sphere of a concrete poem. Thereby it becomes clear that the way of thinking (in its pre-lingual sense) is poetic; the process of thinking transforms itself into a genuine poetic progress, and vice versa the structure of a poem turns out to be part of a creative development of thinking. By contrast, the described transformative process elucidates an impact of contemporary poetics, because transformation as a core issue is mostly only referred to linguistic, social, or cultural aspects.

The volume is devoted to the approach of the philosopher Karl Joël, which he presented under the title “Der Ursprung der Naturphilosophie aus dem Geiste derMystik” in 1906. Although the times have changed, it is worth pointing out the sources from which Joël drew, according to the conviction that gave rise to the present volume. Just as he himself asks about the origin of the philosophy of nature, so the contributions to this volume will enquire about the origin of his own thought. After a presentation of Joël’s concept (Schwaetzer), the three epochs to which he primarily recurs will be considered: Antiquity (Schneider), the Renaissance (Cuozzo) and German Idealism (Hueck), including Late Idealism (Hernández). Finally, there is a view from the present (Thomas). In a narrower sense, the question of the present volume is situated in the area of a philosophy of nature of the Anthropocene. It discusses the thesis that the philosophy of nature arises from mysticism without being dissolved in it, but that the former must not deny its origin Joël thus offers a concept of science that productively questions current understandings and is at the same time embedded in an anthropology that also takes seriously the mental and spiritual in man and the cosmos.

In the so-called Anthropocene, we pose anew the question of what man is. If humankind wants to face present challenges, the preconditions of our “Weltanschauung” come into view. Whereas in the past one used to link cultures by factors such as geography or national identity, today it seems necessary to expand the parameters of cultural comparison. Therefore, different forms of consciousness have had to be analysed as different cultural types. Aiming to describe these forms, the 15th century view is of relevance because it sets the course for the modern reflexive form of consciousness and its sciences – but also its alternatives. With that in mind, this article will focus on the example of Nicholas of Cusa. It shows that art and technology can be understood as manifestations of two different types of consciousness. One type, concerning technology and science, refers to the “anima sensibilis”, including a discursive capacity oriented towards sensual perception. The other type legitimizes and guarantees the first and consists in judging; this pure, mental process has to be actively generated. Cusanus named this type of consciousness as “viva imago”, which forms itself towards a “viva substantia”.

Johannes Kepler's thinking represents a central turning point in the development of the modern understanding of atmosphere. Kepler takes up the ancient conception of the cosmos as a whole divided into living and animated spheres, but reshapes it using specifically modern scientific and epistemological approaches. This gives rise to a view of the Earth as an animated organism, which prefigures modern concepts of atmosphere against the background of a comprehensive vitality of nature. Furthermore, Kepler's embedding of his reflections in the context of astrological prognostics enriches the modern aesthetic discussion with a remarkable perspective: prognostic, i.e. temporal, perception of atmosphere.
