Ok, so. Context. Right. I think that Douglas Adams transcends context. Yes, indeed, every other sentence is a quotable nugget of goodness. But it's also wonderful prose.
From Dirk Gently's Holistic Detective Agency:
"If the Universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don’t. It’s like a human body, you see. A few cuts and bruises here and there don’t hurt it. Not even major surgery if it’s done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make."
For The Long Dark Tea-Time of the Soul:
"It can hardly be a coincidence that no language on Earth has ever produced the phrase, '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."
From various parts of THHGTG:
"He hoped and prayed that there wasn't an afterlife. Then he realized there was a contradiction involved here and merely hoped that there wasn't an afterlife."
And:
"What to do if you find yourself stuck with no hope of rescue: Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems more likely, consider yourself lucky that it won't be troubling you much longer."
