In chapter seven Mills sets out what is thought to be his vision of Sociology. He writes of the need to integrate the social, biographical, and historical versions of reality in which individuals construct their social milieus with reference to the wider society (Mills, 1959, 132-134).
He argues that the nature of society is continuous with historical reality. In doing so, Mills writes of the importance of the empirical adequacy of theoretical frameworks. He also writes of the notion of a unified social sciences. This he believes is not a conscious effort but is a result of the historical problem-based discourses out of which the disciplines developed, in which the divisions between the disciplines become increasingly fluid (Mills, 1959, 136-140). Thus, Mills sets out what he believed to be a problem-based approach to his conception of social sciences (140-142).
