Etc.

Terrence Kilmartin the great literary editor of the Observer never went to the office but ran the books pages from Soho pubs (hiring taxis to take the page proofs to Fleet Street). All kinds of young literary types hung around him, and the price for being in his company was they had to drink a great deal. One day one came to him and said, "Terry, I've met this girl." "Good for you," said Terry. "We're going to be married and I can't spend all day and night drinking in Soho anymore. But I want you to know, I'm not stopping because she's made me stop. The truth is I just don't enjoy it anymore." Kilmartin raised his haggard face and his bloodshot eyes bored into the ignorant whelp. "Do you think," he bellowed. "Do you think that any of us do this because we ENJOY it ?"

       
Thomas Hardy, Jude The Obscure

People go on marrying because they can't resist natural forces, although many of them may know perfectly well that they are possibly buying a month's pleasure with a life's discomfort.

We are linked by blood, and blood is memory without language.

If someone could definitely prove to me that people are happier and healthier under a system of “free love” than marital monogamy, I would just think “This just proves that people’s desires are wicked. Even more reason for coercion!
