Thomas Metzinger is a German philosopher. He currently holds the position of director of the theoretical philosophy group at the department of philosophy at the Johannes Gutenberg University of Mainz and is an Adjunct Fellow at the Frankfurt Institute for Advanced Studies.He has been active since the early 1990s in the promotion of consciousness studies as an academic endeavor.In 2003 he published the monograph Being No One. In this book he argues that no such things as selves exist in the world: nobody ever had or was a self. All that exists are phenomenal selves, as they appear in conscious experience. He argues that the phenomenal self, however, is not a thing but an ongoing process; it is the content of a "transparent self-model."Metzinger is praised for his grasp of the fundamental issues of neurobiology, consciousness and the relationship of mind and body. However, his views about the self are the subject of considerable controversy and ongoing debates.Excerpted from Wikipedia.
