Book excerpt: "A critical analysis of courtly love and medieval troubador literature, this book claims that both traditions were instrumental in the construction of the modern subject and its preparation for life in the highly regulated societies of the modern world. Relating troubadour texts to the rise of commerce, luxury commodities, social differentiation, the centralization of authority, and the crusades, the author proposes that western romantic love, from its courtly beginnings, eroticized the forms and values of the early European commercial economy and nation-states -- playing a key role in the subjection of medieval hearts, minds, and bodies to the disciplines of emerging modern powers." -- Back cover.
