Jean-Jacques Rousseau was one of the most engaging yet enigmatic philosophers of the eighteenth century. He wrote with a flair and directness unique among great thinkers, yet beneath the surface of his works there is an extraordinarily complex theory of human nature and society. His diverse body of writing often leaves students struggling to find a coherent philosophical outlook. Rousseau: A Guide for the Perplexed is a clear and thorough account of Rousseau's major works and ideas, providing an ideal guide to the complicated thought of this key philosopher. 

Translated into Portugese as:

I regard his study as one of the two or three best treatments of the Social Contract in any language. In addition to providing a clear and deep account of Rousseau’s thought, Simpson considers its relevance to contemporary liberal theory. He does so without distorting either Rousseau’s thought or that of the contemporary thinkers he discusses. He succeeds in showing that Rousseau is not merely a precursor, but is also a valuable interlocutor in modern debates.

A fine study, full of ideas ... clearly and straightforwardly written.

In a lucidly written introduction and six chapters, Simpson elegantly disentangles four different kinds of liberty in the thought of Rousseau: natural, civil, democratic, and moral...Simpson’s book is a pleasure to read and important for thinking through many pressing political questions...the aims of his book are excellently carried out
