This open textbook series currently includes volumes on the Philosophy of Mind, Ethics, Logic, Philosophy of Religion, Epistemology, and Aesthetic Theory and Practice, and it will eventually include nine volumes. “We envision the books as helping to orient students within the topic areas covered by the chapters, as well as to introduce them to influential philosophical questions and approaches in an accessible way. The books may be used for course readings on their own, or in conjunction with primary source texts by the philosophers discussed in the chapters. We aim thereby to both save students money and to provide a relatively easy route for instructors to customise and update the resources as needed.” - Logical Reasoning
