'Heydt's scholarship is formidable. For those immersed in the literature of the period, this book will further their researches. For those, like this reviewer, who lack background knowledge in which to place the great figures, Heydt supplies a huge amount of information that could not otherwise be obtained except by great (and even tedious) labour. All those interested in [eighteenth-century] ethics are in his debt.' David McNaughton, Notre Dame Philosophical Reviews
