Dominique Lestel has been developing for several years as a “philosophical ethology” which explores how the human is constituted through his life shared with the other than human (animals, plants, fungi, quasi-autonomous artifacts and ghosts). In this perspective he studies the metaphysical dimensions, epistemological, ethical, epistemological, aesthetic, ecological and political alive facing the convergence of NBTIC technologies (nanotechnology, biotechnology, information technology and cognition). Methodologically, he tries to practice a “field of philosophy” that leads the philosopher to compromise with the world (and he headed Amazon a life shared research program with the animal in Teko Amerindians (Tupi Guarani) with his Italian colleague Egle Barone) – and porosities between philosophical practice and artistic practices of particular interest to him. He also tried to introduce in France the important thinkers who are still there partially or completely unknown as the Norwegian Arne Naess, American Paul Shepard, or the Australian Val Plumwood. Very conscious of the international dimension of contemporary thought, he has held positions in research or teaching in many foreign universities (University of California, MIT, Boston University, School of the Institute of Art of Chicago, University of Montreal , Macquarie University (Sydney), Keio University, Tokyo University, etc.). Before joining the Department of Philosophy, he introduced the teaching of cognitive science at the ENS with the physicist Jean-Pierre Nadal and logician Giuseppe Longo in the 90s and was a founding member of the Department D ‘Cognitive Studies. For several years, until 2013, he was responsible for the team of Eco-ethology and cognitive ethology of the National Museum of Natural History.
