During the two centuries since the publication of 'The Wealth of Nations,' the main activity of economists, it seems to me, has been to fill the gaps in Adam Smith's system, to correct his errors and to make his analysis vastly more exact.

The pollution problem is always seen as someone who was doing something bad that has to be stopped. To me, pollution is doing something bad and good. People don't pollute because they like polluting. They do it because it's a cheaper way of producing something else.

In my long life, I have known some great economists, but I have never counted myself among their number nor walked in their company.

People have used my views for purposes which are very different from mine.

Like lots of baby boomers, I was brought up on archaic anthropomorphism. Upstanding Christian dogs. Rabbits with family values. Because the ancient texts and pictures were sacred - Potter, Milne and the rest. Even concerned parents who knew Freud and Jung never saw the contradictions in feeding us on them.

As the father of two daughters, the ongoing struggle for women's equality is very personal for me. That's why it has been an honor during my time in Congress to support women's rights by advocating for reproductive rights, equal pay, access to paid maternity leave and quality child care.

While I have never learned to use a computer, I am surrounded by family and friends who carry information to me from blogs, Facebook, Twitter, and various websites.

The national team was like a second family for me. I will always carry those 13 years of my life in my heart.
