For Grayling, work on technical problems is only one aspect of philosophy. Another aspect, one which has been at the centre of philosophy's place in history, has more immediate application to daily life: the questions of ethics, which revolve upon what Grayling calls the great Socratic question, 'How should one live?'. In pursuit of what he describes as 'contributing to the conversation society has with itself about possibilities for good lives in good societies', Grayling writes widely on contemporary issues, including war crimes, the legalisation of drugs, euthanasia, secularism, human rights and other topics in the tradition of Polemics. He has articulated positions on humanist ethics and on the history and nature of concepts of liberty as applied in civic life. In support of his belief that the philosopher should engage in public debate, he brings these philosophical perspectives to issues of the day in his work as a writer and as a commentator on radio and television.
