We are not thinking machines that feel; rather, we are feeling machines that think.

I continue to be fascinated by the fact that feelings are not just the shady side of reason but that they help us to reach decisions as well.

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.

When you deal with something like compassion for physical pain, which we know is very, very old in evolution - we can find evidence for it in nonhuman species - the brain processes it at a faster speed. Compassion for mental pain took many seconds longer.

We remove ourselves from the experience itself to a surrogate of the experience, which is whatever measure you take from the brain, be it the electroencephalogram or magnet encephalography or say functional magnetic resonance. So it's pretty tough to make those comparisons.

If I use the word consciousness, in our lab, in our institute, what we mean is the special quality of mind, the special features that exist in the mind, that permit us to know, for example, that we, ourselves, exist, and that things exist around us.

How can you have this reference point, this stability, that is required to maintain the continuity of selves day after day?
