The philosophical work of Adam Węgrzecki is guided by questions about man. Węgrzecki speculates about various the various concepts of humanity that have arisen in philosophical thought throughout history, and he shows the difficulties in formulating views on human nature, its stability, and its variability. His anthropological thought forms an attempt to reconcile opposing positions on this matter. He bases his theory on the notion of a personal entity, that is, a subject. The subject functions as a focal point of Węgrzecki’s anthropological considerations, which include discussions of concepts of identity, of being oneself, of freedom. In his view, the (personal) subject is the foundation on which the identity of the person is realized through the individual who is being him (or her) self. Węgrzecki often refers to representatives of the phenomenological tradition, in particular to Roman Ingarden and Max Scheler, as well as to the renowned anthropologists, Arnold Gehlen and Helmut Plessner. The most striking characteristic of Adam Węgrzecki’s thinking is his normative approach to being oneself: for him, this denotes a task, specifically, the task of self-determination in the face of values. Self-determination therefore has an ethical dimension, which is expressed by the call to actively “lead one’s life”.
