This brief text assists students in understanding Rawls' philosophy and thinking so they can more fully engage in useful, intelligent class dialogue and improve their understanding of course content. Part of the "Wadsworth Notes Series", (which will eventually consist of approximately 100 titles, each focusing on a single thinker from ancient times to the present), "On Rawls" is written by a philosopher deeply versed in the philosophy of this key thinker. Like other books in the series, this concise book offers insight into the thinking of a notable philosopher, which should better enable students to engage in reading and to discuss the material in class and on paper.
