Towards a Practical Form of Epistemology: The Case of Green Chemistry

This paper explores how chemists are transforming their own current background in order to act upon the world without jeopardizing life. In this respect, I will envisage science as both a system of propositions and a set of engaged practices. The scrutiny of chemical innovations will allow me to query the concepts of paradigm and that of scientific community. In doing so, I will connect the philosophy of science with the philosophy of technology so as to think about our relation with the world.
