Julien Nédélec imagines a three-way tour of his exhibition, for which he has enlisted the help of a judge, Thomas Giraud, and a philosopher of science, Vincent Israel-Jost.

Thomas Giraud is a judge and has a doctorate in Philosophy of Law.

Vincent Israel-Jost (Strasbourg, 1977) holds a PhD in mathematics applied to medical imaging (University of Strasbourg, 2006) and a PhD in Philosophy of Science (University of Paris 1, Panthéon-Sorbonne, 2011). He is the author of a work on scientific observation published by Classiques Garnier (2015). Currently a FNRS research fellow at the Catholic University of Louvain, he lives in Paris where he is also involved in several musical projects (Vitaphone, Jorg Feudenfjord, Hygiène Intime and Félicalm) as a composer, guitarist, producer and singer.
