Book excerpt: Henri Lefebvre's three-volume Critique of Everyday Life is perhaps the richest, most prescient work by one of the twentieth century's greatest philosophers. The first volume presented an introduction to the concept of everyday life. Written twenty years later, this second volume attempts to establish the necessary formal instruments for analysis, and outlines a series of theoretical categories within everyday life such as the theory of the semantic field and the theory of moments. The moment at which the book appeared—1961—was significant both for France and for Lefebvre himself: he was just beginning his career as a lecturer in sociology at Strasbourg, and then at Nanterre, and many of the ideas which were influential in the events leading up to 1968 are to be found in this critique. In its impetuous, often undisciplined prose, the reader may catch a glimpse of how charismatic a lecturer Lefebvre must have been.
