quality of everyday life, and inhibit real self-expression. The critique of everyday life was crucial because it was for him only through the development of the conditions of human life—rather than abstract control of productive forces—that humans could reach a concrete utopian existence. Lefebvre's work on everyday life was heavily influential in French theory, particularly for the Situationists, as well as in politics (e.g. for the May 1968 student revolts). The third volume has also recently influenced scholars writing about digital technology and information in the present day, since it has a section dealing with this topic at length, including analysis of the (1977); key aspects of information theory; and other general discussion of the "colonisation" of everyday life through information communication technologies as "devices" or "services". The social production of space Lefebvre dedicated a great deal of his philosophical writings to understanding the importance of (the production of) space in what he called the reproduction of social relations of production. This idea is the central argument in the book The Survival of Capitalism, written as a sort of prelude to (1974) (The Production of Space). Lefebvre contends that there are different modes of production of space (i.e. spatialization) from natural space ('absolute space') to more complex spaces and flows whose meaning is produced in a social way (i.e. social space). Lefebvre analyzes each historical mode as a three-part dialectic between everyday practices and perceptions (), representations or theories of space () and the spatial imaginary of the time (). Lefebvre's argument in The Production of Space is that space is a social product, or a complex social construction (based on values, and the social production of meanings) which affects spatial practices and perceptions. Lefebvre argued that every society—and, therefore, every mode of production—produces a certain space, its own space. Lefebvre's concept has been criticised: e.g. in The Urban Question, Manuel Castells. Many responses to Castells are provided in The Survival of Capitalism, and some such as Andy Merrifield argue that the acceptance of those critiques in the academic world would be a motive for Lefebvre's effort in writing the long and theoretically dense The Production of Space. In "Actually-Existing Success: Economics, Aesthetics, and the Specificity of (Still-)Socialist Urbanism," Michal Murawski critiques Lefebvre's dismissal of actually existing socialism by showing how socialist states produced differential space.
