“A striking and radical rereading of the first Critique through the concept of ‘epigenesis.’ . . . Mensch’s reading is bold and innovative; it deserves to be debated at length by Kant scholars.” 

Radical Philosophy

“Mensch’s attempt to interpret Kant’s transcendental philosophy in relation to eighteenth-century life sciences is original and exciting. … Mensch convincingly shows that questions concerning the origin of cognitions strongly informed Kant’s philosophy. This result is important, since many philosophers, often operating in the wake of Peter F. Strawson’s analytic Kant interpretation, have ignored these types of questions when studying Kant. In short: Mensch’s book is a good example of the fruitful integration of Kant studies with history of science.”

International Studies in the Philosophy of Science

“In this concise and tightly argued monograph, Mensch has demonstrated . . . Kant’s continual and critical attentiveness to the work of the emergent life sciences across the eighteenth century. She shows a clear grasp of what that scientific work took up and what its philosophical implications were—both for the scientists and for Kant. . . . Her account of how Kant came to understand the thinking of the naturalists over the course of the eighteenth century and relate it to his own quest for a transcendental ground of reason in self-generation is very well wrought.”

Kantian Review

“Kant’s Organicism is an excellent and fascinating philosophical-historical study, well worth reading for any Kant scholar. It also provides a rich source of stimulating ideas for contemporary Kantian philosophers.”

Studies in the History and Philosophy of Science

“Jennifer Mensch’s account of how Kant came to understand the thinking of the naturalists over the course of the eighteenth century and relate it to his own quest for a transcendental ground of reason in self-generation is very well wrought. She has made sense of a number of elements that I knew separately but had not seen in this compelling conspectus.”

“In recent years a host of editions, translations, monographs, and articles have introduced Anglo-American readers to a Kant different from the anti-metaphysical epistemologist and rigorous ethicist of earlier scholarship. Kant has emerged as a pragmatic anthropologist, a physical geographer, and a natural historian. Jennifer Mensch’s book seeks to unify the two pictures of Kant by tracking the formative background of the Critique of Pure Reason in Kant’s own original account of the biological development of individuals and species. Her provocative epigenesist reading challenges the distinction between matters of fact (quid facti) and grounds of validity (quid iuris) in Kant’s account of a priori knowledge.”
