is an objective stage of research—where one looks at the relations of the social space and the structures of the field; while the second minute must be a subjective analysis of social agents' dispositions to act and their categories of perception and understanding that result from their inhabiting the field. Proper research, Bourdieu argues, thus cannot do without these two together. Science and objectivity Bourdieu contended there is transcendental objectivity, only when certain necessary historical conditions are met. The scientific field is precisely that field in which objectivity may be acquired. Bourdieu's ideal scientific field is one that grants its participants an interest or investment in objectivity. Further, this ideal scientific field is one in which the field's degree of autonomy advances and, in a corresponding process, its "entrance fee" becomes increasingly strict. The scientific field entails rigorous intersubjective scrutinizing of theory and data. This should make it difficult for those within the field to bring in, for example, political influence. However, the autonomy of the scientific field cannot be taken for granted. An important part of Bourdieu's theory is that the historical development of a scientific field, sufficiently autonomous to be described as such and to produce objective work, is an achievement that requires continual reproduction. Having been achieved, it cannot be assumed to be secure. Bourdieu does not discount the possibility that the scientific field may lose its autonomy and therefore deteriorate, losing its defining characteristic as a producer of objective work. In this way, the conditions of possibility for the production of transcendental objectivity could arise and then disappear. Reflexivity Bourdieu insists on the importance of a reflexive sociology in which sociologists must at all times conduct their research with conscious attention to the effects of their own position, their own set of internalized structures, and how these are likely to distort or prejudice their objectivity. The sociologist, according to Bourdieu, must engage in a "sociology of sociology" so as not to unwittingly attribute to the object of observation the characteristics of the subject. They ought to conduct their research with one eye continually reflecting back upon their own habitus, their dispositions learned through long social and institutional training. It is only by maintaining such a continual vigilance that the sociologists can spot themselves in the act of importing their own biases into their work. Reflexivity is, therefore, a kind of additional stage in the scientific epistemology.
