I asked Mrs Botogol: "Do you think each of us is a coherent single self, or do you think we all contain a multiplicity? Different people, if you like, in the same body?"
"Please don't call me Mrs Botogol when we are at home, dear" she said.
At the ICA opinion was mixed: Rita Carter believed she has no free will and no self. "I, zombie" if you will - I am a zombie and so is my avatar. I didn't agree, but it's such a nihilistic viewpoint that is rather difficult to take issue with: arguing with a self-identified zombie is like arguing with the SatNav. I wished I hadn't praised her book, but comforted myself that perhaps I probably couldn't help it.
On the panel Raymond Tallis gallantly declared his faith in Rita Carter "I believe you have a self" he said and I was surprised to find myself on Tallis's side, arts against science, as Carter frowned at him (rather ungraciously I thought, but then it must he hard for her, surrounded by unthinking zombies acting mechanically and without imagination. A bit like being at work)
I jotted down random nuggets from each speaker. The most intriguing was the idea of different-sized selves (mania being swelling of self, and depression a diminution). The most confounding was the question of whether we are still ourselves when we dream...ouch.
The most amusing factoid (ie it appeals directly to my prejudices) is that, apparently, when a Myers-Briggs test is repeated there is only a 25% chance of finding the same personality type.
That would explain it then.
