“...it's a mistake to think that happiness is the goal. I'm not sure I understand." "I was referring to the goals which you in your civilization are so good at setting yourselves, and which incidentally allow you to achieve many interesting things. But happiness is a different thing altogether. If you try to achieve it, you have every chance of failing. And besides, how would you ever know that you achieved it?

She found a way of making the exciting men nicer and that was by leaving them. But then, they weren't exciting anymore either.”

“Or rather, he was sad because that morning he'd understood that he'd understood nothing, because while he still understood nothing he wasn't sad at all, but now that he'd understood that he'd understood nothing he felt sad, if you follow.”

“Some people, very many actually, both men and women, complained of having enjoyed a very loving relationship with someone, but of no longer feeling the same way despite still being very fond of that person, with whom they generally lived.”
