To accurately assess the moral status of fossil fuels, we must understand how and to what extent they positively and negatively affect the lives of human beings. This is a key theme in Alex Epstein’s first book, The Moral Case for Fossil Fuels. While writing the revised edition, The Moral Case for Fossil Fuels 2.0, Epstein developed a human flourishing-based framework for evaluating any technology, from GMOs to social media to self-driving cars. In this talk, Epstein will elaborate further on this framework, showing how it can help us to think clearly and objectively not only about technologies, but also about personal productiveness, recreation, rejuvenation, and other crucial aspects of life.
