Chapter 1 reconstructs the conceptual history of tact as a social, ethical, and aesthetic category. Starting out with Voltaire’s 1769 definition that marks tact’s fundamental paradigm shift from a sense of feeling to a form of sociability, I reconstruct the word’s ensuing career as a key concept in 19th- and 20th-century pedagogical, philosophical, and literary discourse. I discuss tact’s history within the context of the demise of the ancien régime and the rise of the bourgeois subject, reflecting on a variety of different historical and philosophical explanations (Elias, Adorno, Foucault). I reconstruct how and why, around 1800, tact turns into a key philosophical term, depicting an intuitive form of empirical judgement (Kant). I show how, in the second half of the 19th century, tact, understood as an individual deviation from normative structures, came to occupy a key position in the method dispute between the humanities and the natural sciences (Helmholtz). I conclude by reflecting on how psychological tact went on to become a key category in modern and contemporary hermeneutics, uniting the otherwise antagonistic work of scholars incl. Adorno, Gadamer, Barthes, Felski, and Macé.
