Here.  An excerpt:

I've changed my views a lot over the years. I'm much less reactionary than I used to be. I was opposed to homosexual marriage in my book Sex and Reason, published in 1992, which was still the dark ages regarding public opinion of homosexuality. Public opinion changed radically in the years since. My views have changed about a lot of things. I've become much more concerned with long prison sentences; softer on drugs; more concerned with consumer protection, the environment and economic inequality; less trustful of purely economic analysis—the last partly because of the crash of 2008 and the ensuing economic downturn. That shook some of my faith in economic analysis. And developments in psychology have required qualification of the "rational choice" model of economic behavior. So my views have changed a lot. You don't want a judge who takes a position and feels committed to it because he thinks it's terrible to change one's mind.
