I can not understand how anyone claiming an interest in the politics of the Left could start reading George Orwell's "Homage to Catalonia" and not quickly complete reading it.
Yet in this article, Nick Cohen of all people states "....I did start Homage to Catalonia a few years ago, but to my shame I never finished it."
This might help to explain why Nick finds it difficult to oppose both Fascism and Imperialism at one and the same time, even though in his book "What's Left?" he talks of the need to be able to "walk and chew gum at the same time".
A full study of Orwell would put him on this wavelength. Anyone not hooked on Orwell, should start scanning Gauche. And (praise indeed) as good as Orwell himself is Bernard Crick's biography of him.
