Discussion of a paper by Thierry NGosso entitled ‘On the Relevance of Teaching Creationism at the University’, as part of the meetings of the Hoover Chair at UCLouvain. The discussion focuses on (a) the notion of teaching and academic critical thinking, (b) the variety of epistemological contexts (eg between the faculties of sciences, law or theology), (c) the limits of separation models that would preclude the interdisciplinary and intersubjective treatment of the thematic.
