Locke and Rousseau, if in different ways and different degrees, accepted the idea of the Social Contract: Hume, more historically minded, and more conservative in his convictions, was its critic.

'There is something,' he seems to say, 'in your diffe...

For the study of the great writers and thinkers of the past, historical imagination is the first necessity. Without mentally referring to the environment in which they lived, we cannot hope to penetrate below the inessential and temporary to the absolute and permanent value of their thought. Theory, no less than action, is subject to these necessities; the form in which men cast their speculations, no less than the ways in which they behave, are the result of the habits of thought and acti...

Its dazzling mixture of fantasy and satire is narrated by a personification of Folly, dressed as a jester, who celebrates youth, pleasure, drunkenness and sexual desire, and goes on to lambast human pre...

Burke's seminal work was written during the early months of the French Revolution, and it predicted with uncanny accuracy many of its worst excesses, including the Reign of Terror. A scathing attack on the revolution's attitudes to existing institutions, property and religion, it makes a cogent case for upholding inherited rights and established customs, argues for piecemeal reform rather than revolutionary change - and deplores the influence Burke feared the revolution might have in Brita...
