As a senator, I worried every day about the size of the federal deficit. I did not spend a single minute worrying about the effect of gays on the institution of marriage. Today it seems to be the other way around.

The Senate is indeed a deliberative body, and that quality serves the nation well. A slow-moving government helps us maintain a stable government. But slow moving is not the same as immobile.

The Federal Reserve bank buys government bonds without one penny.

In the Middle East, Iraq, Sudan, the former Yugoslavia and Northern Ireland, and many other places in the world, religion has been so divisive that people have killed one another, believing they were doing the work of God.

Plenty of kind, decent, caring people have no religious beliefs, and they act out of the goodness of their hearts. Conversely, plenty of people who profess to be religious, even those who worship regularly, show no particular interest in the world beyond themselves.

I was to Japanese visitors to Washington what the Mona Lisa is to Americans visiting Paris.

I think a lot of us share a fear that we and people we love will lose control of our own destinies at the end of life.

The starting point is the recognition that throughout history, religion has been a cause of bloodshed, and it remains so today. Because religion has contributed to the world's problems, it must develop specific and practical ways to help solve those problems.

Many, if not most, Americans can imagine a fate worse than death, and it is a seemingly interminable process of dying. For them, it is frightening that politicians can find ways to interject themselves into this sad process.

The loudest voices we hear are those who advocate conflict, divisiveness.

We are seekers of the truth, but we do not embody the truth. And in humility, we should recognize that the same can be said about our most ardent foes.
