Stephen Darwall (born 1946) is a contemporary moral philosopher, best known for his work developing Kantian and deontological themes.

He was named Andrew Downey Orrick Professor of Philosophy at Yale University in 2008.

[11] In addition to his works on ethical theory, Darwall has worked on the history of ethics with publications like The British Moralists and the Internal ‘Ought’: 1640-1740 (1995)[12] and Modern Moral Philosophy: From Grotius to Kant (2023), the first in a planned series tracing the development of moral philosophy through the twentieth century.

[13] His book The Heart and Its Attitudes (2024) examines the role of second-personal attitudes in fostering personal relationships and emotional connections, building on his earlier work on mutual accountability and morality.

[14] His other publications include Impartial Reason (1983), Philosophical Ethics (1998), and Welfare and Rational Care (2002), alongside seven edited anthologies, such as Moral Discourse and Practice (1997), co-edited with Allan Gibbard and Peter Railton.
