As women in industrial societies join the paid workforce, they gain the economic means to depart unhappy marriages more easily.

At first I assumed hate was the opposite of love. But it isn't. The opposite of love is indifference.

I don’t think we’re an animal that was built to be happy; we are an animal that was built to reproduce.

As societies continue to loosen their standards regarding what is appropriate female and male behavior, I think we are going to realize we have not only underestimated women, but also men.

Like most animals, we're wired to associate height with power.
