Abstract
Odd Langholm has previously given us three important book-length studies on price and value, wealth and money in the Aristotelian tradition, and the Aristotelian analysis of usury. The present work is an effort to integrate virtually all the secondary literature on economic speculation by every significant figure who studied or taught at Paris during its golden age. This is no mere compilation of prior research, however. The author has made detailed examinations of unedited manuscripts and rare incunabula in order to present a panorama of diverse speculators, each with his own intellectual genotype. In offering new interpretations and important nuances to previously established conclusions, this work may well serve as an indispensable reference for future investigations into medieval and early modern economic thought.
