Cornelius Castoriadis made a significant and distinctive contribution to the development of the notion of the dialectic of control. In the first instance, Castoriadis formulated an important reconceptualization and restatement of the Marxist conception of the central contradiction of capitalism. He argued that capitalism depended on the creativity of workers while excluding them from effective control. Similarly, Castoriadis sought to extend the Marxist analysis of those tendencies present within the structuration of the labour process that may prefigure a socialist reorganization (...) of production. Castoriadis’s analyses of capitalism during the phase of his involvement with Socialism or Barbarism are likewise informed by his assessment of state socialist regimes. In particular, this assessment provided important insights into the modalities of control in modern society and the complications of transcending forms of institutional domination in modernity. It will be argued that some of the distinctive intentions of Castoriadis’s later elucidation of the social imaginary can be traced to his interpretation of bureaucratic capitalism and that this is evident in his subsequent accounts of the capitalist imaginary. In his later theory, Castoriadis interprets the problem of the dialectic of control in terms of the relationship between instituting and instituted society. Castoriadis’s analysis of capitalism during the period of Socialism or Barbarism will be situated in the wider debates over capitalism at that time. Similarly, Castoriadis’s departure from some of the philosophical sources that influenced the development of the notion of the dialectic of control will be explored. (shrink)
