Weber had major reservations about the implications of the operation of so seemingly inexorable a process, which he sometimes referred to as creating an ‘iron cage’ that would increasingly restrict individuality. He recognized that a narrow calculation of ‘instrumental rationality’ was likely to conflict with 'substantive rationality’ i.e. the rationality of outcomes appraised in terms of wider human objectives. At the same time, however, in a world ‘disenchanted’ by rationality, he did not believe that a 'strictly scientific’basis existed for a generalized conception of human interests or human needs. Human beings possess freedom of action, and must therefore ultimately make their own choices (see also VALUE FREEDOM AND VALUE NEUTRALITY).
Other theorists have taken a more optimistic view of the outcome of the rationalization process. HABERMAS, for example, has suggested that ‘human interests’ will be identifiable in a context in which a truly democratic critical discourse exists (see also CRITICAL CULTURAL DISCOURSE). In general, however, sociologists have remained more agnostic on such issues (see also FORMAL AND SUBSTANTIVE RATIONALITY).
