This thesis is an attempt to reflect on the theme of phenomena and sensuous world in the context of environmentalism. It deals with the condemnation of phenomena in the modern era science and especially in the contemporary neo-Darwinian biology, and with various attempts at rehabilitation of sensory perception as a relevant way of relating to the world in biology (Adolf Portmann, Hans Driesch) and philosophy (phenomenology, particularly Maurice Merleau-Ponty). The main subject of the thesis is the eco- phenomenology of David Abram and a comparison of his approach with the one held by contemporary biology. Based on this comparison it is argued in what manner may the thoughts of David Abram, and the effort to rehabilitate phenomena in general, be of benefit to the environmental discourse, particularly in terms of forming an original epistemology and ontology and concerning the ethical motivations.
