Immanuel Kant
Kant published other important works on ethics, religion, law, aesthetics, astronomy, and history. These include the "Universal Natural History" (1755), the "Critique of Practical Reason" (1788), the "Metaphysics of Morals" (1797), and the "Critique of Judgment" (1790), which looks at aesthetics and teleology.
Allen W. Wood
Wood has written prolifically on many subjects in moral and social philosophy, and publications he has authored include: "Kant's Moral Religion" (1970), "Kant's Rational Theology" (1978), "Karl Marx" (1981), "Hegel's Ethical Thought" (1990), "Kant's Ethical Thought" (1999), "Unsettling Obligations" (2002), "Kant" (2004), "Kantian Ethics" (2007) and "The Free Development of Each: Studies in Freedom, Right and Ethics in Classical German Philosophy". He is also working on a book continuing his 'Ethical Thought' series entitled "Fichte's Ethical Thought", fulfilling his earlier suggestion that "having written a book on "Hegel's Ethical Thought" and a book on "Kant's Ethical Thought", I should... write a book... on "Fichte's Ethical Thought".
