Abstract

What are thought experiments? How and why do they work? What do they reveal about the nature of rationality? These are the problems that I attempt to solve in my inquiry. ;Regarding the first problem, my preliminary answer can be stated as follows: Thought experiments are our imaginative explorations of new ways to experience and understand our world. It is my conviction that the ability to try out new ways of experiencing and understanding various phenomena is essential to the growth of our knowledge and is constitutive of our sense of meaningfulness in our world. This conviction is the guiding idea of my study. ;This conviction is debatable. It cannot be the starting point of my argument. My tactic, rather, is to select and examine certain kinds of thought experiments, to show how and why they work, and to uncover the rationality that supports their implementation. I will show that the rationality is not specific to thought experimentation but is constitutive of all sorts of human organizing activities. The importance of a proper analysis of thought experiment is that it can give us an insight into human rationality in general. ;Thought experiments have played a central role in scientific development in human history. Yet almost nobody has any insight into how and why they work. But now recent research on cognition, especially research on meaning, imagination, concepts, reasoning, and cognitive development has begun to shed light on the imaginative structure of thought experiments. Therefore, we now have a means to begin to analyze the central mechanism of thought experimentation. My inquiry suggests what such an analysis would look like
