"While I am interested both in economics and in philosophy, the union of my interests in the two fields far exceeds their intersection"

This quote by Amartya Sen suggests that although he is interested in both economics and philosophy, his interests in the 2 fields are not limited to their crossway. Instead, he is interested in the union of the two fields, which goes beyond the crossway of the two. This indicates that he is interested in the ways in which economics and philosophy can be combined to produce something new and special. He is not just thinking about the ways in which the 2 fields overlap, however in the ways in which they can be combined to produce something brand-new. This quote recommends that Amartya Sen has an interest in exploring the capacity of integrating economics and viewpoint to produce something that is higher than the sum of its parts.
