Almost always, when I'm on TV, the producers who call me, who negotiate what we're going to say, is a woman.

Today, most women are surrounded by ingenious gadgets. They don't grow the peas or raise the chicken that they serve for dinner; instead they hunt and gather in the grocery store. They go through catalogs or department stores to buy clothes instead of shearing sheep, carding wool, and weaving cloth for skirts and coats and blankets.

I think romantic love evolved to enable you to focus your mating energy on just one individual at a time, thereby conserving mating time and energy.

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.

The brain was not built to walk into a bar, where you know nobody, and start a conversation. That's not the way humanity has courted.

People live for love. They kill for love. They die for love. They have songs, poems, novels, sculptures, paintings, myths, legends. It's one of the most powerful brain systems on Earth for both great joy and great sorrow.

Romantic love is an addiction: a perfectly wonderful addiction when it's going well, and a perfectly horrible addiction when it's going poorly.
