What is Kuhn’s Problem?

Inspired by the work of Kuhn, we might want to develop an account of science that explains how it is that while much of science involves the investigation of a world as articulated by a paradigm, the scientist is nevertheless an observer and rational interpreter of a mind-independent world that does not change its character over time. Kuhn himself recognizes that there is a challenge here that he does not know how to meet. I argue that progress can be made on this challenge by carefully examining and criticizing Kuhn’s account of deliberation in science. Inspired by certain views about Gestalt psychology and examples such as the duck/rabbit picture, Kuhn takes deliberation in science to be a consequence of seeing things a certain way, rather than rational deliberation in science making new ways of seeing things possible. I argue that the most serious problems of Kuhn’s view of science stem from this fact, and that we can free ourselves from these problems by not following Kuhn here. In particular, I argue using material from Hanson and Peirce that we should think of the revolutionary scientist as being revolutionary not merely in virtue of seeing things in a new way, but rather for showing – typically through painstaking deliberation – that certain conjectures connected with new ways of seeing the world are reasonable (even prior to anything like inductive confirmation.) This makes coming to see the world differently a deliberative process that is importantly unlike seeing a rabbit/duck picture differently. Such a way of thinking allows us to view the articulation of a new paradigm as a deliberative process that does not take some paradigm or other for granted, but rather as a deliberative process that interrogates existing orthodoxy for its suitability to survive into the next paradigm. The result is a (sketch of a) view of science that maintains much of what is important to Kuhn, but departs from him where his view is least convincing.
