Thomas Wagner’s book is not a history of sociology in the traditional disciplinary sense. Rather than reconstructing the internal development of theories or schools, it traces how sociological analysis and language came to function as a privileged medium through which modernity was articulated in West Germany during the first two decades after 1945. Across fifteen chapters, including a prologue and an epilogue, the book develops its narrative through carefully chosen scenes that foreground lived intellectual experience as much as formal theoretical debate.

From early on, Wagner makes clear that the central analytical pairing of the book is Theodor W. Adorno and Arnold Gehlen. Their juxtaposition is not intended as a contrast between mutually exclusive positions, but as a way of illuminating how divergent political orientations nonetheless converged around a shared sociological problematic. Both thinkers occupy pivotal positions in Wagner’s reconstruction of postwar discourse, and their relation to one another structures much of the book’s argument.

A recurring theme is the remarkable continuity of academic institutions after 1945, including the persistence of personnel shaped by the Nazi period. Against expectations of radical rupture, Wagner shows how, on a personal and professional level, left-leaning and conservative thinkers were often able to coexist, collaborate, and maintain cordial relations. This coexistence is not treated as a moral anomaly but as an index of the broader postwar condition, in which ideological boundaries were blurred by the pressures of reconstruction.

One of the book’s most striking observations concerns the unexpected affinities between left-leaning and conservative thinkers. Again and again, Wagner returns to the fact that figures such as Wolfgang Harich from the GDR, a very young Jürgen Habermas still deeply engaged in Marxology (57–58), and even Bertolt Brecht (169–171) could, at specific moments, find more theoretical proximity to Gehlen than to Adorno. This is not presented as a biographical curiosity, but as a structurally significant pattern. Its conceptual core lies in the centrality of activity in Gehlen’s theory of the human (29), which emphasizes action and the necessity of institutions for stabilizing individual and social life. Wagner convincingly suggests that this emphasis could resonate with Hegelian and Marxian motifs of labor and social mediation, even across sharp political divides.

At the same time, these observations raise tensions that the book does not fully resolve. Under the broad rubric of modernity, left and right sometimes appear so closely interwoven that ideological distinctions risk being levelled. One occasionally wishes for a stronger theoretical throughline that would take a clearer position on the political stakes of these proximities. Yet this levelling effect can also be read productively. Read in a generous light, the book’s form itself can be understood as reflecting the ideology-fatigue characteristic of postwar German public discourse which the book itself thematizes (145). Rather than imposing a totalizing framework, Wagner allows contradictions and ambiguities to stand, capturing a historical moment in which grand ideological syntheses had lost much of their credibility.

The contrast between Adorno and Gehlen is particularly instructive in this regard. For Adorno, sociology appears as a form of critical social theory oriented toward emancipation and a working-through of the Nazi past. For Gehlen, by contrast, sociology functions as a handmaiden to administration, tasked with stabilizing political institutions and managing social complexity (27). Despite this fundamental divergence, both thinkers assess the dangers of modern society in terms of an erosion of the subject (246). The proximity of this diagnosis to Gehlen’s concerns complicates any simple opposition between critical and conservative sociology and helps explain why both could operate within a shared sociological language.

Methodologically, the book distinguishes itself through its extensive use of private correspondence, biographical detail, and accounts of public cultural events. Discussions of everyday practices, such as Adorno’s and Gehlen’s media consumption and television viewing habits (181–183), are not treated as anecdotal curiosities. Rather, they illuminate how sociological sensibilities were embedded in daily life and mediated through emerging forms of mass culture. The emphasis on such material makes the book accessible without sacrificing analytical depth and supports a compelling diagnosis of postwar academic and public self-understanding.

If the book has a silent key figure, it is Gehlen. Although he is not always explicitly foregrounded, the epilogue traces his influence on both left intellectual traditions and contemporary right-wing rhetoric in public discourse. Wagner argues that Gehlen’s concepts often reappear implicitly, forming foundational elements in theories that distance themselves from his conservatism while nonetheless retaining key anthropological and institutional assumptions (268). This final gesture gives the book contemporary resonance and underscores its broader significance.

Overall, Wagner offers a nuanced and intellectually generous account of how sociology came to function as a central language of modernity in postwar Germany. By foregrounding lived intellectual practices, unexpected affinities, and institutional continuities, the book challenges rigid narratives of rupture and ideological polarization. Its greatest strength lies in showing that sociology’s postwar authority did not derive from theoretical consensus or moral clarity, but from its capacity to articulate ambivalence in a society marked by the search for new forms of self-understanding.
