AC Grayling likes to remind people that, on average, we can hope to live for around 1,000 months. Awareness of this fact fuels the incredible energy of Britain’s most prolific and erudite popular philosopher. Haste and serious thought are not necessarily good bedfellows, however, which is why Grayling’s public success has been matched with some professional suspicion.
