The philosophy of social science is equally necessary for philosophers who think their interests are wholly limited to epistemology or metaphysics, for the social sciences raise fundamental questions about knowledge and human action.The philosophy of social science aims to explain the connections between philosophy and economics, sociology, political science, parts of psychology, history, and the disciplines at the intersections of these subjects.This article begins with an explanation of why philosophy is relevant to the human sciences, and explores the problems raised by alternative explanatory strategies of the human sciences. Finally, this article provides five problems that social scientists and philosophers have challenged every step in the chain of reasoning: the claim that the natural sciences show progress and the social sciences do not; the assumptions about what progress in the growth of knowledge consists of; the role of laws in providing knowledge; the purported explanations of why the social sciences have not yet uncovered any laws; and the prescriptions about how they should proceed if they hope to uncover laws.
