Conservatives say human beings are people who are primarily concerned with self-interest, and that's what they should be concerned with - self-interest and individual responsibility. They shouldn't be paying for anybody else's health care or anything else like that. As a result, government is something that should be absolutely minimal. It's not there for your overall protection and empowerment - it's not there to offer protection against disease or natural disasters or bad products or companies who sell you fallacious mortgages and so on.

One of the things cognitive science teaches us is that when people define their very identity by a worldview, or a narrative, or a mode of thought, they are unlikely to change-for the simple reason that it is physically part of their brain, and so many other aspects of their brain structure would also have to change; that change is highly unlikely.

If you're a progressive, you can find lots of people who call themselves conservatives, but who agree with you on lots of things. There are people who call themselves conservatives, but who love the land as much as any environmentalist. Progressives share a number of common values with people who call themselves conservatives. Barack Obama has understood that very well. What he calls bipartisanship is not adopting conservative views, but finding where people who consider themselves conservatives share with him and other progressives these fundamental American values.

Liberals have a set of folk theories that are fallacious. One of them comes from the Enlightenment, and the assumption is that you are supposed to be logical. They assume all you have to do is tell people the facts and they will reason to the right conclusion. This is utterly ridiculous. Thought is mainly metaphorical. The frames trump all the facts.

Metaphor is pervasive in everyday life, not just in language but in thought and action. Our ordinary conceptual system, in terms of which we both think and act, is fundamentally metaphorical in nature.

Empathy - that is, caring about people and acting responsibly on that care, not just for yourself, but for others - this is something that Barack Obama understands very well. He was a professor of constitutional law at the University of Chicago for ten years. As an expert on the Constitution and on our family values, he understands very well that the country is fundamentally about caring for one another. The day after his speech, he was interviewed on CNN, and Anderson Cooper asked him what patriotism was. He said patriotism begins with caring for one another.

If we are to know ourselves, philosophy needs to maintain an ongoing dialogue with the sciences of mind.
