Abstract
Thought experiments have a long and illustrious history. But in spite of their acknowledged importance, there has until recently been remarkably little said about them. How do they work? Why do they work? What are the different ways in which they work? And above all: How is it possible that just by thinking we can learn something new about the world? This paper surveys some of the recent approaches, including my own , and discusses their various prospects. Chief among the alternatives is John Norton′s argument view. The paper ends by drawing attention to some of the outstanding problems in thought experiments. These are some of the issues that will likely be the focus of attention and research in the future
