This document discusses the debate between reductionism and holism. Reductionism takes the view that a complex system is nothing more than the sum of its parts, while holism argues that the whole is greater than the sum of its parts and possesses characteristics that emerge from the organization and interaction of the parts. The document provides examples of attempting to apply reductionism to fields like economics, psychology, biology and physics. It notes that while reductionism breaks things down into their constituent parts, holism recognizes that organization plays a role and the whole possesses properties not found by analyzing only the parts. In the end, it questions how we can resolve the tension between these two perspectives.
