ABSTRACT
The central concerns of the philosophy of science as a whole divide into two areas. One of these areas, perhaps the traditionally more dominant side, encompasses such questions as: Is scientific knowledge possible? If so, how? What methods of reasoning do scientists use? What is the role of observation and experiment in scientific reasoning? Are theories justified that concern entities and processes that cannot be observed? This area is where philosophy of science overlaps with epistemology, the theory of knowledge.
