Love is about bottomless empathy, born out of the heart’s revelation that another person is every bit as real as you are. And this is why love, as I understand it, is always specific. Trying to love all of humanity may be a worthy endeavor, but, in a funny way, it keeps the focus on the self, on the self’s own moral or spiritual well-being. Whereas, to love a specific person, and to identify with his or her struggles and joys as if they were your own, you have to surrender some of your self.

I've moved away from that sort of deep-ecological extremism. I started to think: what can we do for wild birds right now? I don't want these particular species to disappear.

THE CORRECTION, when it finally came, was not an overnight bursting of a bubble but a much more gentle letdown, a year-long leakage of value from key financial markets, a contraction too gradual to generate headlines and too predictable to seriously hurt anybody but fools and the working poor.
