Moreover, metaphor is typically viewed as characteristic of language alone, a matter of words rather than thought or action. For this reason, most people think they can get along perfectly well without metaphor. We have found, on the contrary, that 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.

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.

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.

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