The development of urban studies during the 1960s and 1970s was an offshoot of mainstream social sciences which, at least in Latin America, were formulated from a critical standpoint based largely on a renovated Marxism and the rise of the structuralisms. Now that this framework's apparently solid base has come under question in the so‐called ‘paradigm crisis', what is the outlook for urban studies and, in general, for the critical social sciences? This article poses a series of ideas which hopefully will contribute to a discussion on these and other aspects of a theoretical debate which cannot be ignored by urban researchers.
