Where does one science end, and another begin? How do the sciences interact at their boundaries, if there are boundaries at all? And if different sciences tell us different
things on the same subject matter, how can we tell which is/are right? Most abstractly put, these are the questions I shall address in this thesis. Of course, these questions are
partly historical and sociological, and must be answered as such. However, my project is philosophical. That is, I want to learn some methodological, epistemological as well
as metaphysical lessons in attempting to answer these questions. Specifically, I will be exploring the boundaries of two branches of behavioural and social science, namely,
economics and psychology.
