Here is a link to an interesting article by Ian Hunter about the relevance of some of the novel’s concepts today. Here is a little:
The most influential English author of the 20th century may well have been Eric Arthur Blair, a.k.a. George Orwell, the subject of Jeffrey Meyers’s fascinating biography, Orwell: Wintry Conscience of a Generation. This is the kind of book that forces one to evaluate its subject afresh; Mr. Meyers manages to separate Orwell the man from Orwell the legend, while allowing the reader to trace the development of both. Given what had already been written about Orwell, it is a tribute that nearly every page contains some fresh revelation about Orwell’s life or some new insight into the significance of his work.
Orwell’s most influential novels (Animal Farm and Nineteen Eighty-Four) were sometimes dismissed by critics as Cold War polemics but it is fascinating how they yield fresh insight into, say, the war in Afghanistan.
Each time I hear terms such as “collateral damage” or “holy war,” I recall the Ministry of Information in Oceania.
