This volume completes a trilogy of Steven M. Cahn’s shorter writings that includes The Road Traveled and Other Essays (2019) and A Philosopher’s Journey (2020). Included here are his contributions to three philosophical debates: first, whether events are fated to occur; second, whether God is knowable; and third, whether morality can conflict with happiness. The book contains not only Cahn’s essays but also edited versions of the writings to which he is responding, thereby putting his remarks into context and rendering them accessible to all. These pieces make clear why Professor Cahn is regarded as one of the leading philosophy teachers of his generation.
