This book reintroduces the work of Raymond Aron and demonstrates the pertinence of his thought for reflection on social interaction and the human condition. One of Europe’s leading intellectuals, Aron was primarily a sociologist, but his writings transcended disciplinary boundaries and engaged with philosophy and political theory. A clear and concise introduction to Aron’s thought on a variety of major socio-political questions—including the importance to social thought of historical understanding, the connection between ideology and socio-political thinking, the development and nature of sociology itself, labor relations, international relations, and trans-disciplinary socio-political thought—Reintroducing Raymond Aron explains Aron’s work within its historical context, underlining its importance and relevance for contemporary sociological and political problems. It will therefore appeal to scholars and students of sociology, sociological theory, political theory, and international relations.
