Abstract

These books make significant contributions to contemporary realism. Psillos’s book presents an excellent overview of the central components of current scientific realism, the main challenges to it, and the most promising strategies for defending it. It is a work of remarkable clarity, synthesis, and argumentative rigor. Psillos’s realism is committed to three claims: Scientific theories make irreducible assertions about unobservable entities which are literally true or false ; In the case of mature, successful theories, their success provides good reason for taking their assertions about unobservables to be true, or approximately so ; and What makes scientific theories true or false is the mind-independent natural-kind structure of reality.
