The paper aims to discuss the remarks and criticisms that have been raised in the essays discussing my book The Life of Concepts. Hegel, Bachelard, Canguilhem. I focus firstly on the relationship that I establish between conceptual history and epistemology of concepts; then, I consider some purely epistemological criticisms; finally, I focus on the problem of political science and its relationship with the social sciences. In the last section of the paper, I attempt to address the more comprehensive question of the role of philosophy and its relationship to sciences.
