Aron presents rich portraits of these three thinkers, drawing from them what remains of enduring worth, even as he distances himself from Durkheim's project for a science of society, Pareto's exaggerated critique of humanitarianism, and Weber's tragic pessimism. Aron's book is essential for clarifying his profound indebtedness to and crucial divergences from the thought of Max Weber, the sociologist par excellence, in Aron's view.
Together with volume 1, which treats the work of Montesquieu, Comte, Marx, and Tocqueville, it forms the definitive survey of the great social thinkers to date. Yet, as Daniel J. Mahoney and Brian C. Anderson explain in their introduction, Main Currents is more than a survey; it is above all a challenge to contemporary social science to retain the ambition of an older, philosophically informed sociology to present an interpretation of modern society and to reflect on the meaning of universal history.
