This is the first cultural history of terms of emotion found in German, French, and English language encyclopaedias since the late seventeenth century. Insofar as these reference works formulated normative concepts, they documented shifts in the way the educated middle classes were taught to conceptualise emotion by a literary medium targeted specifically to them. As well as providing a record of changing language use (and the surrounding debates), many encyclopaedia articles went further than simply providing basic knowledge; they also presented a moral vision to their readers and guidelines for behaviour.
