'Does Anything Really Matter?' gives philosophers that were critized by Derek Parfit in his books 'On What Matters' an opportunity to respond to Parfit's criticisms. It includes essays on Parfit's views by Richard Chappell, Andrew Huddleston, Katarzyna de Lazari-Radek and Peter Singer, Bruce Russell, and Larry Temkin. A third volume of 'On What Matters', in which Parfit engages with his critics and breaks new ground in finding significant agreement between his own views and theirs, is appearing as a separate companion volume.
