In this dialogue with José Manuel Sánchez Ron around his book Ciencia, política y poder. Napoleón, Hitler, Stalin y Eisenhower, the author reflects on the historian’s role in explaining the world we live in. The topics arising in the course of the conversation have been organized into three main sections.

The first is an approach to the author and his thought, so we know where he is coming from. The second, starting from the contents of his book – four historical case studies illustrating the complex relations between science, politics and power –, explores the idea that science is inseparable from political, military and economic power. And the third focuses on how history can help us understand today’s world.
