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.

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.

For real human beings, the only realism is an embodied realism.

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.

The essence of metaphor is understanding and experiencing one kind of thing in terms of another.

We now know, from the latest research about neurons, that we are hard-wired for empathy. We're hard-wired for cooperation. That is something about what we are as people - what it means to be a human being. And what Barack Obama was addressing was not just race or just the nature of politics. The great speeches address who we are as people, what it means to be a human being.
