Abstract
This article uses a history of concept formation focused on Pierre Bourdieu's probabilism to provide the groundwork for a probabilistic sociology. We argue that not only was Bourdieu a probabilist, but that reframing probability along heterodox lines holds empirical promise when it is also linked to new concept formation, as evident in the case of Bourdieu. For the anglophone sociological field, probability is of primary significance for method and epistemic commitment. Sociological theory continues to react to the integral role of probability used for the purposes of sociological knowledge but finds very little in the way of concept formation that does not adopt the same commitments as the methodologists. The history we outline retrieves a different approach, one which finds Bourdieu aligned with objective probability borrowed from the sociology of Max Weber. This version of probabilism locates probability directly in the world and makes it a source of concept formation without the intervention of the methodologists. This article follows Bourdieu as he recognizes objective probability in the work of Weber (around 1973) and then engages in novel concept formation on these grounds. Ranging between spaces of objective probability (fields), spaces of randomness (games of chance), and spaces of determinism (apparatus), Bourdieu's mature probabilism reveals the conceptual and meta-methodological differences that come with making probability objective. Probabilistic expectations derive from the world itself, rather than existing as part of explanation or method. Specifically, this history of concept formation reveals a looping relation between objective probability (chances) and learned probability (expectations) that, as Bourdieu himself appreciated, holds wide-ranging implications for best knowledge practices and empirical sociological research.
