I assume the buyer will know that William Godwin was the husband of Mary Wolestonecraft and father of Mary Shelley, and father-in-law of the poet Shelley. (The great quartet are buried in a churchyard in Bournemouth town centre, if you are nearby). While the Terror raged in France and Pitt responded with censorship and arrests of radicals in Britain, Godwin wrote this first statement of anarchism. It is a plea for the abolition of the state and its replacement, not by some sort of selfish and competitive individualism, but voluntary association based on simple inner goodness and personal conscience.
It would be redundant to say more: if the reader is aware of the historical context, between Enlightenment and Romanticism, and at the moment the French Revolution turned into a totalitarian nightmare, it all makes instant sense.
200+ years on it remains lucid, readable, thought-provoking and even inspiring. Utopian though Godwin was, his humanity and absolute scepticism about power and those who seek it cannot but command respect.
For a £20 or £15 book to come down to half the price seems reasonable, though would it not be lovely to find a hardback version in some local second-hand bookshop. 40 years ago these anarchist, socialist and other radical paperbacks were the main stock-in-trade of university and university-town bookshops: from the LSE bookshop windows one could spot Godwin, Marx and Gramsci from 30 paces--now they seem to have been relegated to the back shelves. How times change!
So, recommended in any case, and recommended at the price.
