A Foray into the Worlds of Plants and Fungi

In his extensive and revolutionary work, the biologist and philosopher Jakob von Uexküll examined the animal kingdom, laying the first foundations for a wider reflection on non-human animal agency in ecosystems. However, the scientist did not include in his reflection on Umwelt plants and fungi, widely considered passive organisms in the 1900s. In this paper, we will try to find the contact points between the biologist’s theories and contemporary botanical discoveries, taking into account some of the findings on plant agency, communication, and interaction even with fungi, crucial actors in the vegetal organization of the territory. The core of the work will be to demonstrate that plants could fit in an integrated and extended theory of Umwelt abandoning the “zoocentric” perspective that permeated the studies on botanical species. To achieve this aim, it will be necessary to first deconstruct the historical theorization of plants’ passivity, which has ancient roots and was enforced in some philosophical perspectives of the 20th century. Consequentially, with two focuses, the first one on communication and the second one on agency, the paper will highlight the possibilities and horizons that could be opened through a comparison between the theories of von Uexküll and nowadays botanical breakthroughs.
