The research points pretty clearly to the rise of companionate marriage, and I just think it's going to keep being popular, for the very simple reason that it's basically the only way to afford a family life in the 21st-century in advanced economies. It's one of the major reasons for the spike in income inequality. Surgeons used to marry their secretaries. Now they marry other surgeons.

Look at The Iliad, there's all this stuff about men loving children. The King of Sparta was the most brutal warrior of ancient Greece, and the only thing he liked to do was horse around with kids when he was back from slaughtering. One thing that feminism revealed is that being a distant patriarchal figure was not something men wanted to be. They want to be more involved in the lives of their children, and you can see that once they're allowed to have that connection, they crave it.

Marriage is this black box which is the key to all social and political problems; the family is the unit.

Marriage is an an inherently contradictory state. It involves the fusion of two people into one thing. And it's also love, and it's a lot of work, and it's got glory in its drudgery.

Almost all the voices in history have been men, but on this one question of gender, men don't talk about it. This has nothing to do with women; it has to do with men.

Men talk about masculinity through sports and clothes. They don't talk about gender, they talk about LeBron James and whether it's okay to wear lipstick and eyeliner. They're not getting to the question at hand, which is, "What does it mean to be a man when the traditional values of masculinity are eroding incredibly rapidly?'

When you ask single men in their 20s, "Do you want children?" they want children more than women do. Again, economics drive this. If you're a 29-year-old woman, having a baby is going to seriously blow up your career. If you're a 29-year-old man, it isn't.
