This book provides a framework for Augustine's understanding of will, an aspect of his thought that has proven to be both essential and inscrutable. Han-luen Kantzer Komline demonstrates that Augustine's view is "theologically differentiated," comprising four distinct types of human will, which correspond to four different theological scenarios. This account of the Augustinian will gives a comprehensive picture of the development and mature shape of Augustine's thinking on this vital yet perennially puzzling topic.
