Source: The Long Dark Tea-Time of the Soul (1988), Ch. 13
Context: My own strategy is to find a car, or the nearest equivalent, which looks as if it knows where it's going and follow it. I rarely end up where I was intending to go, but often I end up somewhere I needed to be.

This had made many people very angry and has been widely regarded as a bad move.

“Anything invented after you're thirty-five is against the natural order of things.”
The Salmon of Doubt (2002)
Context: Anything that is in the world when you're born is normal and ordinary and is just a natural part of the way the world works. Anything that's invented between when you're fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you're thirty-five is against the natural order of things.

Context: If you try and take a cat apart to see how it works, the first thing you have on your hands is a nonworking cat. Life is a level of complexity that almost lies outside our vision; it is so far beyond anything we have any means of understanding that we just think of it as a different class of object, a different class of matter; 'life', something that had a mysterious essence about it, was God given, and that's the only explanation we had. The bombshell comes in 1859 when Darwin publishes On the Origin of Species. It takes a long time before we really get to grips with this and begin to understand it, because not only does it seem incredible and thoroughly demeaning to us, but it's yet another shock to our system to discover that not only are we not the centre of the Universe and we're not made by anything, but we started out as some kind of slime and got to where we are via being a monkey. It just doesn't read well.

Context: It can hardly be a coincidence that no language on Earth has ever produced the expression "As pretty as an airport." Airports are ugly. Some are very ugly. Some attain a degree of ugliness that can only be the result of a special effort. This ugliness arises because airports are full of people who are tired, cross, and have just discovered that their luggage has landed in Murmansk (Murmansk airport is the only exception of this otherwise infallible rule), and architects have on the whole tried to reflect this in their designs.
