This article discusses symmetry as an analytical tool for sociological analysis. Symmetry is presented as a property of social formations and a way to generate information about them through their mutual comparisons. The concept thus displaces the old dichotomy between individual and society. The latter forces to think in terms of wholes and parts, unduly limiting the possibilities at hand by keeping individuals as prisoners of societies, as it were. Symmetry opens the door for more alternatives by making room for (...) more social formations at the same time. To develop this concept, the article turns to both Niklas Luhmann’s systems theory and Harrison White’s network theory which are presented as enacting an “order from noise” approach (as opposed to an “order from order” approach). The article then reconstructs a whole spectrum going from social formations at a high level of symmetry to social formations at a low level of symmetry. At the first end, we have social formations like groups that define the identities of persons (or even define persons as identities). At the other end, we have entire functional sectors (like politics, science, law, economy, etc.) whose chief characteristic is to be asymmetric to each other (so that doing politics, for instance, is unlike doing science and vice-versa).
