Thomas Metzinger is a German philosopher. He has been active since the early 1990s in the promotion of consciousness studies as an academic endeavour. As a co-founder, he has been particularly active in the organization of the Association for the Scientific Study of Consciousness (ASSC), and sat on the board of directors of that organisation from 1995 to 2008. He served as president of the ASSC in 2009/10. Metzinger is director of the MIND group and has been president of the German cognitive science society from 2005 to 2007. In English he has published two edited works, Conscious Experience (1995), and Neural correlates of consciousness: empirical and conceptual issues (2000). The latter book arose out of the second ASSC meeting, for which he acted as local organizer. In 2015, together with Jennifer M. Windt, he published the Open MIND-collection, containing more than 100 original, peer-reviewed open access-papers from philosophy of mind, cognitive science, and neuroscience.
