You never know what your history is going to be like until long after you're gone.

I have faith, as I did when I announced my stem-cell decision in 2001, that science and ethics can coexist.

I know the human being and fish can co-exist peacefully.

If we're an arrogant nation, they'll resent us; if we're a humble nation, but strong, they'll welcome us. And our nation stands alone right now in the world in terms of power, and that's why we've got to be humble, and yet project strength in a way that promotes freedom.

It is time to set aside the old partisan bickering and finger-pointing and name-calling that comes from freeing parents to make different choices for their children.

Iran is obviously part of the problem. They sponsor Hezbollah. They encourage a radical brand of Islam.

We are bound by ideals that teach us what it means to be citizens. Every child must be taught these ideals. Every citizen must uphold them.... I ask you to be citizens. Citizens, not spectators. Citizens, not subjects. Responsible citizens building communities of service and a nation of character.
