This document summarizes Daniel Little's views on social science as presented in his work "Action in History and Social Science". It discusses key concepts such as social regularities, causal explanations, and the relationship between agents and structures. Little argues that social science lacks universal laws and strong regularities. Instead, causal explanations should focus on causal powers, mechanisms, and how structures constrain yet are also shaped by individual agency. As a result, prediction in social science is limited compared to natural sciences.
