Abstract
Della Volpe was a professor of philosophy, one of the leading theoreticians of the Italian Communist Party in the 50s and 60s, and one of the few prominent intellectuals to retain party membership following the Hungarian revolt. Nonetheless, his Marxism is distinctly heterodox. The main thrust of Rousseau and Marx, which contains an essay of that name as well as several short papers on Soviet legality and "materialist methodology," is to establish certain continuities between Marx’s thought and earlier philosophy. Marx is here depicted as attempting to solve a problem first stated by Rousseau, the problem of egalitarian liberty, and as applying the logic of modern experimental science to moral and political questions.
