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.

In 'Self Comes to Mind' I pay a lot of attention to simple creatures without brains or minds, because those 'cartooned abstractions of who we are' operate on precisely the same principles that we do.

There's something that intervenes and is very important which has to do with value. Value in the true biological sense, which is that contrary to what many people seem to think, taking it at face value - sorry for the pun - we do not give the same amount of emotional significance to every event.

I think it's possible to a certain extent to make those comparisons. The problem is the detail with which the comparison can be made. Of course, the first place to make such a comparison would be to ask for a testimony from different people and have people report on what they experience.

Something may have happened before, and yet this thing that happened just after may be so important that you don't even know about the thing that happened before and when you tell your story to yourself, or to someone else, it's going to be told not on the basis necessarily of the time course, but rather on the basis of how it was valued by you.

We're seeing it the same way, we're hearing the same way, we have the same conception of the situation. And so, for all purposes, we are operating with a very similar perception.

The self is a perpetually recreated neurobiological state.
