influenced and analysed the May 1968 student revolt. Lefebvre introduced the concept of the right to the city in his 1968 book Le Droit à la ville (the publication of the book predates the May 1968 revolts which took place in many French cities). Following the publication of this book, Lefebvre wrote several influential works on cities, urbanism, and space, including The Production of Space (1974), which became one of the most influential and heavily cited works of urban theory. By the 1970s, Lefebvre had also published some of the first critical statements on the work of post-structuralists, especially Michel Foucault. During the following years he was involved in the editorial group of Arguments, a New Left magazine which largely served to enable the French public to familiarize themselves with Central European revisionism. Lefebvre died in 1991. In his obituary, Radical Philosophy magazine honored his long and complex career and influence: The critique of everyday life One of Lefebvre's most important contributions to social thought is the idea of the "critique of everyday life", which he pioneered in the 1930s. Lefebvre defined everyday life dialectically as the intersection of "illusion and truth, power and helplessness; the intersection of the sector man controls and the sector he does not control", and is where the perpetually transformative conflict occurs between diverse, specific rhythms: the body's polyrhythmic bundles of natural rhythms, physiological (natural) rhythms, and social rhythms (Lefebvre and Régulier, 1985: 73). The everyday was, in short, the space in which all life occurred, and between which all fragmented activities took place. It was the residual. While the theme presented itself in many works, it was most notably outlined in his eponymous three-volume study, which came out in individual installments, decades apart, in 1947, 1961, and 1981. Lefebvre argued that everyday life was an underdeveloped sector compared to technology and production, and moreover that in the mid 20th century, capitalism changed such that everyday life was to be colonized—turned into a zone of sheer consumption. In this zone of everydayness (boredom) shared by everyone in society regardless of class or specialty, autocritique of everyday realities of boredom vs. societal promises of free time and leisure, could lead to people understanding and then revolutionizing their everyday lives. This was essential to Lefebvre because everyday life was where he saw capitalism surviving and reproducing itself. Without revolutionizing everyday life, capitalism would continue to diminish the
