Reason and Experience in Mendelssohn and Kant provides the first in-depth examination of the lifelong intellectual relationship between two of the greatest figures of the European Enlightenment, Immanuel Kant (1724-1804) and Moses Mendelssohn (1729-1786). Both were engaged in a common project of striking the right balance between rationalism and empiricism. They sometimes borrowed from one another, often disagreed with one another, and can usefully be compared even when they did not directly interact. Guyer examines a series of comparisons and contrasts: their arguments and conclusions on a range of metaphysical issues, including proofs of the existence of God, immortality, and idealism; their shared interests in aesthetics; and their path-breaking work on the "religion of reason" and the separation of church and state. Setting the work of both philosophers in historical context, Guyer shows that, where Kant sometimes provides deeper insight into the underlying structure of human thought, Mendelssohn is often the deeper student of the variety of human experience. This is evident above all in their treatments of aesthetics and religion: Mendelssohn recognizes more deeply than Kant the emotional impact of art, and while Kant imagines that organized religion will one day be superseded by pure morality, Mendelssohn argued that organized religion in all its varieties seems here to stay, and so toleration for religious variety is an inescapable requirement of human morality. Based on an exhaustive study of a wide range of texts, this study demonstrates the on-going relevance of Kant and Mendelssohn to modern thought.

Paul Guyer presents the first in-depth examination of the lifelong intellectual relationship between two of the greatest figures of the European Enlightenment, Immanuel Kant and Moses Mendelssohn. He explores their influence on each other and their disagreements, with particular focus on metaphysics, religion, and aesthetics.

Religion within the Boundaries of Mere Reason is a key element of the system of philosophy which Kant introduced with his Critique of Pure Reason, and a work of major importance in the history of Western religious thought. It represents a great philosopher's attempt to spell out the form and content of a type of religion that would be grounded in moral reason and would meet the needs of ethical life. It includes sharply critical and boldly constructive discussions on topics not often treated by philosophers, including such traditional theological concepts as original sin and the salvation or 'justification' of a sinner, and the idea of the proper role of a church. This new edition includes slightly revised translations, a revised introduction with expanded discussion of certain key themes in the work, and up-to-date guidance on further reading.

This collection of essays by one of the preeminent Kant scholars of our time transforms our understanding of both Kant's aesthetics and his ethics. Guyer shows that at the very core of Kant's aesthetic theory, disinterestedness of taste becomes an experience of freedom and thus an essential accompaniment to morality itself. At the same time he reveals how Kant's moral theory includes a distinctive place for the cultivation of both general moral sentiments and particular attachments on the basis of the most rigorous principle of duty. Kant's thought is placed in a rich historical context including such figures as Shaftesbury, Hutcheson, Hume, Burke, Kames, as well as Baumgarten, Mendelssohn, Schiller, and Hegel. Other topics treated are the sublime, natural versus artistic beauty, genius and art history, and duty and inclination. These essays extend and enrich the account of Kant's aesthetics in the author's earlier book, Kant and the Claims of Taste (1979).

Immanuel Kant famously said that he was awoken from his "dogmatic slumbers," and led to question the possibility of metaphysics, by David Hume's doubts about causation. Because of this, many philosophers have viewed Hume's influence on Kant as limited to metaphysics. More recently, some philosophers have questioned whether even Kant's metaphysics was really motivated by Hume. In Knowledge, Reason, and Taste, renowned Kant scholar Paul Guyer challenges both of these views. He argues that Kant's entire philosophy--including his moral philosophy, aesthetics, and teleology, as well as his metaphysics--can fruitfully be read as an engagement with Hume. In this book, the first to describe and assess Hume's influence throughout Kant's philosophy, Guyer shows where Kant agrees or disagrees with Hume, and where Kant does or doesn't appear to resolve Hume's doubts. In doing so, Guyer examines the progress both Kant and Hume made on enduring questions about causes, objects, selves, taste, moral principles and motivations, and purpose and design in nature. Finally, Guyer looks at questions Kant and Hume left open to their successors.

Metaphysicians have for centuries attempted to clarify the nature of the world and how rational human beings construct their ideas of it. Materialists believed that the world (including its human component) consisted of objective matter, an irreducible substance to which qualities and characteristics could be attributed. Mindthoughts, ideas, and perceptionswas viewed as a more sophisticated material substance. Idealists, on the other hand, argued that the world acquired its reality from mind, which breathed metaphysical life into substances that had no independent existence of their own. These two camps seemed deadlocked until Immanuel Kant's Critique of Pure Reason endeavored to show that the most accurate theory of reality would be one that combined relevant aspects of each position, yet transcended both to arrive at a more fundamental metaphysical theory. Kant's synthesis sought to disclose how human reason goes about constructing its experience of the world, thus intertwining objective simuli with rational processes that arrive at an orderly view of nature.
