This text explores Martin Heidegger's interpretation of the Greek term fysis (physis), which he translates into German as Walten (ruling or prevailing). The author argues that fysis is not merely growth within a fixed order or the execution of a pre-determined plan, but a dynamic process encompassing deviations and errors. Using the example of a two-headed calf, the text illustrates that even abnormal growth remains a manifestation of fysis rather than its cessation. Growth is characterized as a form of 'blind groping' or experimentation—a trial-and-error process rather than a strictly programmed development. Furthermore, fysis-Walten includes the capacity to respond to external damages and injuries sustained during organic events. Nature attempts to repair such defects, often necessitating practical compromises. Ultimately, the text presents fysis as a living, unpredictable, and adaptive force where perceived flaws are integral to the governance of natural life, reflecting a broader understanding of natural order and its inherent flexibility.
