"Racism is taught in the home. We agree on that? Well, it's very hard to teach racism to a teenager who's listening to rap music and who idolizes, say, Snoop Dogg. It's hard to say, 'That guy is less than you.' The kid is like, 'I like that guy, he's cool. How is he less than me?"
"There are a lot of obstacles in the way of our understanding animal intelligence - not the least being that we can't even agree whether nonhuman species are conscious. We accept that chimps and dolphins experience awareness we like to think dogs and cats do. But what about mice and newts? What about a fly? Is anything going on there at all?"
"Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option."
"The message that I gave on the - on the steps today was that you need to stand for those things that are right and empower the individual. Believe in the power of one person. Don't believe that you can't do it. Everybody wants - everybody wants a shot. That we can all agree on. Beyond that, it becomes politics. I'm not talking politics."
"Life does not agree with philosophy: There is no happiness that is not idleness, and only what is useless is pleasurable."
"I'm not defined by where I came from. I never took part in the rules and hatred that sometimes go along with religion. But if my parents are happy with what they believe, then I'm happy to stay out of their way. We agree to disagree."
"Republicans have been losing the war of words for years now. Now they are just caving because they don't even want to try. I don't agree with that approach."
"I just think Texas and that whole Bible Belt section is so, like, corporate. And I don't agree with organized religion in that respect."
"If we don't get gun-control laws in this country, we are full of beans. To have the National Rifle Association rule the United States is pathetic. And I agree with Mayor Michael Bloomberg: It's time to put up or shut up about gun control for both parties."
"And Barack and I were raised with so many of the same values, like you work hard for what you want in life. That your word is your bond that you do what you say you're going to do. That you treat people with dignity and respect, even if you don't know them and even if you don't agree with them."
