We live in a culture that discourages empathy. A culture that too often tells us our principle goal in life is to be rich, thin, young, famous, safe, and entertained.

Of all the rocks upon which we build our lives, we are reminded today that family is the most important.

The silence killed your faith.

We don't have this huge footprint, we are less likely to be targeted as, you know, occupiers [in Afghanistan and Iraq].

No one in the United States of America should ever be targeted because of who they are, what they look like, or how they worship.

I know starting careers in troubled times is a challenge, but it is also a privilege. Because it's moments like these that force us to try harder, dig deeper and to discover gifts we never knew we had. To find the greatness that lies within each of us. So don't ever shy away from that endeavor. Don't stop adding to your body of work. I can promise that you will be the better for that continued effort as will be this nation that we all love.

There are a lot of very religious scientists around. I think the problem here is that in our school systems, and to some degree - and this is where it is relevant - with school boards around the country that are mandating curriculums and textbooks, you start seeing this weird watering down of scientific fact so that our kids are growing up in an environment - and this connects to what I was saying earlier abou the media - where everything's contested. Where nothing is true.
