Consciousness begins when brains acquire the power, the simple power I must add, of telling a story.

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.

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you experience the emotion of sadness, there will be changes in facial expression, and your body will be closed in, withdrawn.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.

Consciousness permits us to develop the instruments of culture - morality and justice, religion, art, economics and politics, science and technology. Those instruments allow us some measure of freedom in the confrontation with nature.

But whether we want to do it because we want to have people to have a different idea of who we are or not, we do it naturally. So the way we construct our narrative is different from the way we constructed it a year ago. The difference is maybe very small or it may be huge.

A self that is very robust, that has many, many levels of organization, from simple to complex, and that functions as a sort of witness to what is going on in our organisms.

I think it's reasonable to say that even thought, in all likelihood, we have slightly different experiences of reality, they are similar enough to us not to clash. In other words, I'm not, it's very unlikely, in fact, let's say impossible, for you to say the situation in which you and I are in right now, relative to the machinery that is capturing this.
