I watched a fascinating episode in the BBC's 'Horizon' strand yesterday evening, attempting to answer the question "How do we know who we are?".

This was a good summary of the various strands of thinking that have been gathering force around this topic over the last decade as research into it starts to become mainstream science.
The BBC's Horizon page is currently here:
www.bbc.co.uk/horizonAnother good overview (and actually quite detailed) examination of this topic of identity and what makes 'me' think that I am 'me' is in Tor Norretranders' book
"The User Illusion"Both Horizon and Tors share the view that this person we call "I" is probably a synthesis of the several biological brain processes working as a kind of 'network'. And that many of these processes operate out of necessity on an unconscious level.
Tors maintains that because our brains are able to receive and process many millions of bits of information (far more than we could handle consciously) and because memory gives us an evolutionary advantage, then 'consciousness' (the person we think of as 'I') only exists as a kind of librarian in what is actually an almost totally automated library. The librarian is there as a kind of organising principal and comfort factor.
Both Horizon and Tors point to recent research showing that apparently conscious decisions - for example to reach for a glass of water because I'm thirsty - actually take place
unconsciously first.
Horizon repeated experiments which show that this actually unconscious decision-making process happens up to SIX seconds before the conscious part of the brain builds the illusion that it made the decision. The presenter was astounded to discover that the scientists watching him inside a magnetic resonance imager were able to know whether he had decided to press a left or right button before he was consciously aware of his decision!
Horizon also showed how the brain could be fooled into thinking that it was observing itself (and its body, of course) sitting in one place when it was actually a few feet away.
I'm fascinated by all of this because of its profound implications for change work, personal development and emotional intelligence.
It seems that science is able to prove what some philosophers and therapists have been attempting to work with for some time, things like:
1) If I change the inputs to my mind, for example, the kind of tv I watch, or I change my biological processes, for example by sleeping better or exercising more, then the "I" will also be changed
2) I can use my mind to imagine observing myself and introduce the information of my behaviour as part of my unconscious library. I can create a feedback loop that introduces more awareness of the whole me, not just the illusory conscious part, and add more choices about how the whole of that behaves
3) I can be aware that a lot of my reaction to and understanding of other people arises from this amalgam of unconscious processes. Then, I can (a) deliberately use my unconscious to help build better understanding of others and (b) give my internal librarian a little more choice in what reactions I actually let myself express
4) The best change work will balance working at a conscious level with the knowledge that most of what determines a person's sense of self is actually happening at an unconscious level. Working with the whole physiological system, for example reminding somebody how their posture affects their internal confidence and their external ability to relate to others becomes very important. As does working directly at a subconscious level, for example using metaphor and imagery to describe a person's experience, hopes and fears rather than talking more (illusory) directly about them.
I'm also reminded of the Buddhist concept of Anatta, meaning 'no self', in which the mind is nothing but a complex compound of fleeting mental states. Descartes and Bertrand Russell had related things to say - nice to see science catching-up!
How are you doing with your own sense of who you are?
And what does it mean for you if who you think you are is more fluid and unconsciously-determined then we thought?
Please leave a comment because it helps people to express their thoughts too.
