Immanuel Kant’s Religion within the Boundaries of Mere Reason is a seminal text in modern philosophy, ethics, and the philosophy of religion. It is a complex and challenging work, which students and scholars often find difficult to penetrate. This Reader’s Guide provides a ‘way in’ to the text including: philosophical and historical context; an overview of key themes; section-by-section analysis of the text; a chapter on its reception and influence as a classic text of the Enlightenment; and a guide for further reading. It highlights the most important themes and ideas, clarifies certain opaque features, and examines the junctures in the text that are critical for any philosophical assessment of Kant’s argument. Eddis N. Miller offers a sound understanding of Kant’s Religion and the tools for students to philosophically assess Kant’s overall argument.
