The motif of water also has an epistemological dimension: looking at an object in isolation in order to create reliable knowledge is a proven methodological practice. At the same time, however, this isolation always means a loss of contextual knowledge.This is why many innovative fields of research today are characterized by the desire to liquefy overly rigid assumptions, which are often at the beginning of positive knowledge production, in favour of more complex models and thereby expand the contexts to be included. On the one hand, this makes the basis for orientation more uncertain, on the other hand, it seems more suitable for representing and understanding the processes of change in nature and society. The motif of liquefaction loses its metaphorical dimension when it comes to describing manifestations of water as a separate actor in a complex process. This often involves a balancing of forces and quantities. Against this background, scientific research appears to be an attempt to correct imbalances, impending irreversible tipping points and destructive asymmetries through targeted measures and to learn from water in its diverse interrelationships with humans, nature and technology.
Taken consistently, this perspective promises solution concepts for fundamental challenges of the present, whether at the level of basic research or concrete application practice in local and global context.
The ethnologist and linguist Franz Boas (1858-1942), whose interdisciplinary and explicitly culturally relativistic perspective was and still is trend-setting for the challenges of transdisciplinary research on both a local and global scale, is a godfather in the conception of the exhibition. With its combination of narrative, mathematical and technical aspects, his doctoral thesis “Contributions to the knowledge of the colors of water” (1881) in the field of physics, is a striking example of the idea of combining abstract questions with vivid motifs, which also guides the exhibition. His 1886 habilitation lecture at the Friedrich Wilhelm University in Berlin, “Die Eisverhältnisse des arktischen Ozeans” (The ice conditions of the Arctic Ocean), was again dedicated to water, but now as a geographer and anthropologically oriented. Boas’ life-world motif of the colourfulness of water forms a basic motif for the potentials and limits of the generalization of knowledge.
