Values in Science and the Value of Science. Recollections about John Stewart’s Trajectory

Aiming at establishing an objective and disengaged biography of John Stewart would go against his own conception of life, science and thought. In this text, I therefore present some recollections of my encounter and collaborations with John, and sketch some steps of his rich intellectual career. In the continuity of the discussions and disagreements I had the chance to develop with him, I also propose some reflections on the place of values in science, and on the value of science itself.
