David Hume was born three hundred years ago, on 26th April 1711. He lived most of his life in Edinburgh, with only a few improbable interludes: one as tutor to a lunatic, one assisting in a comic-operatic military adventure, and one somewhat more successfully as Embassy Secretary, being a lion in the literary salons of Paris. Apart from these his life was devoted to philosophy, history, literature, and conversation. He is the greatest, and the best-loved, of British philosophers, as well as the emblem and presiding genius of the great flowering of arts and letters that took place in the Edinburgh of the eighteenth century—the Scottish Enlightenment. As with all philosophers, his reputation has gone through peaks and troughs, but today it probably stands higher than it ever has.
