Other books I've given up on include Finnegan's Wake, To The Lighthouse, Middlemarch, although I have read War and Peace it was a very long time ago, and I don't intend to have a re-read any time soon. More recently I've started, but not finished, Midnight's Children, We Need To Talk About Kevin, and The Raj Quartet.
Just writing the words above makes me feel a bit guilty, as if I've failed some important test. And maybe for some people I have. But why? We can't read everything on the planet, and even if we could, why should we? Reading novels is about entertainment, and there seems to me to be no reason why what entertains me should entertain you, and vice versa.
It also takes no account of the life stages we go through. In my teens I started with Georgette Heyer and Jean Plaidy, then gobbled down detective novels, followed by science fantasy before moving on to the complete works of Anthony Trollope in my 20s. In my 30s I read gardening books and lifestyle magazines - but I haven't touched either for years. I've changed my tastes over time and why not?
Being told I 'ought' to read something puts me against it. I'm sure I didn't like The Artist as much as other people seem to have done because all the reviews implied that you 'ought' to, so that put me in a resistant mood from the start.
I would agree that you ought to be kind to those weaker than oneself, or that you ought not to lie or steal or cheat, but reading isn't some moral decision. It can be informative, thought-provoking, mind-expanding and utterly absorbing, but it is, at heart, a form of entertainment. And there's no ought about it.
