We do not merely perceive objects and hold thoughts in our minds: all our perceptions and thought processes are felt. All have a distinctive component that announces an unequivocal link between images and the existence of life in our organism.

Of necessity, the autobiographical self is not just about one individual but about all the others that an individual interacts with. Of necessity, it incorporates the culture in which the interactions took place.

You're not the same after, say, an incredible love affair that went very well or a love affair that went bad. Or something that happens to your health, or something that happened to somebody else's health, that is close to you. Or something that happens professionally.

Emotion operates, very often when you think about how you react to the world, you know, something is happening to you, you're simply going along and you're being confronted by different things, not necessarily very important or significance for your ultimate life, but you are constantly reacting to the world.

Consciousness, much like our feelings, is based on a representation of the body and how it changes when reacting to certain stimuli. Self-image would be unthinkable without this representation.

Imagine, for example, birds. When they look out at the world, they have a sense that they are alive. If they are in pain, they can do something about it. If they have hunger or thirst, they can satisfy that. It's this basic feeling that there is life ticking away inside of you.

When you experience the emotion of sadness, there will be changes in facial expression, and your body will be closed in, withdrawn. There are also changes in your heart, your guts: they slow down. And there are hormonal changes.
