Agnes Callard is a philosopher at the University of Chicago whose work sits at the rare intersection of rigorous academic thought and genuine public provocation. Author of 'Aspiration: The Agency of Becoming' (2018) and 'Open Socrates: The Case for a Philosophical Life' (2025), she argues that Socratic open inquiry - the willingness to be persuaded by better reasons - is not just for intellectuals but for everyone. A Guggenheim Fellow and Lebowitz Prize winner, she writes for The New Yorker, The New York Times, and The Point Magazine, runs the Night Owls public debate series in Chicago, and co-hosts the 'Minds Almost Meeting' podcast with economist Robin Hanson. Known for contrarian takes ('The Case Against Travel'), deeply personal essays, and a living arrangement that keeps her ex-husband as a co-resident, Callard treats philosophy not as a career but as a way of life.
