The era of big government is over.

I ask that all Americans demonstrate in their personal and public lives... the high ethical standards that are essential to good character and to the continued success of our Nation.

We know there are billions of stars and planets literally out there, and the universe is getting bigger. We know from our fancy telescopes that just in the last two years more than 20 planets have been identified outside our solar system that seem to be far enough away from their suns - - and dense enough - - that they might be able to support some form of life. So it makes it increasing less likely that we're alone. But if we were visited someday, I wouldn't be surprised.

Everybody knows that I have tougher ethics rules than any previous President.

We must all be profoundly grateful for the magnificent achievements of our forbearers in this century. Yet perhaps in the daily press of events, in the clash of controversy, we don't see our own time for what it truly is - a new dawn for America.

In science, if the last 50 years were the age of physics, the next 50 years will be the age of biology.

I always get nervous when people start talking about legacies.
