Emotion is set in our genome and that we all have with a certain programmed nature that is modified by our experience so individually we have variations on the pattern. But in essence, your emotion of joy and mine are going to be extremely similar.

We may express them [emotions] physically slightly differently, and it's of course graded depending on the circumstance, but the essence of the process is going to be the same, unless one of us is not quite well put together and is missing something, otherwise it's going to be the same.

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

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.

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.

To me, body and mind are different aspects of specific biological processes.

Feeling of an emotion is a process that is distinct from having the emotion in the first place. So it helps to understand what is an emotion, what is a feeling, we need to understand what is an emotion.
