is a question from Quora, from which my favourite of the many responses was:
Although I am a huge fan of The Hitchhiker’s Guide to the Galaxy in all its incarnations and have been quoting from it nearly all my life, I think Douglas’s single best line of writing actually comes from The Salmon of Doubt (a collection of previously published and unpublished material that was published one year after his untimely death):
This is rather as if you imagine a puddle waking up one morning and thinking, ‘This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn’t it? In fact it fits me staggeringly well, must have been made to have me in it!’ This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, frantically hanging on to the notion that everything’s going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.
