Rudy Professor Emeritus, Philosophy
Marcia Baron's research focuses on moral philosophy, moral psychology, and philosophy of criminal law. Topics she has written on include impartiality in ethics, and the apparent conflicts between on the one hand, loyalty, patriotism, friendship and love, and on the other, impartiality; manipulativeness; self-defense; the provocation defense; mens rea issues, including whether negligence should suffice for criminal liability; sexual consent; justifications and excuses; the value of acting from duty (and just how acting from duty should be understand); and virtue ethics. She is interested in the history of ethics, and has written extensively on Kant's ethics and less extensively on Hume's; she also has an interest in liberalism and political philosophy more generally. She is currently working on a book on self-defense and the reasonable belief requirement.
