I liked early Amis a lot, but I stopped reading him some time ago. I admire Hitchens on literary topics - I think he is very astute. McEwan, I read a bit. But I suppose it's more the ideological phenomenon that they represent together that interests me.
I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.
Sometimes you have to lie. One often has to distort a thing to catch its true spirit.
