Just how free are we?
Fundamental to our self-understanding as humans is the belief that we are responsible for our own actions. Clearly the edges of that get blurred a little when someone's past and upbringing are taken into account, when we factor in the influence of genetic make-up or perhaps chemical imbalances that affect someone's mental state - but there is an incredibly deep-rooted belief in a "self" that is more than merely a prisoner of a physical body/brain.
An article in New Scientist + another bit of Dawkin's book (still not finished - too many other more interesting things to finish!) + a BBC website report have connected to raise the issue...
The BBC picks up this story:
Scientists say they have found the part of the brain that predicts whether a person will be selfish or an altruist.
Altruism - the tendency to help others without obvious
benefit to oneself - appears to be linked to an area called the
posterior superior temporal sulcus.
Using brain scans, the US investigators found this region related to a person's real-life unselfish behaviour.
It's interesting that the scientist involved is quoted as saying "...understanding the function of this brain region may not necessarily identify what drives people like Mother Theresa..." - but why not?
Dawkins would say - though I'm sure much more eruditely (and more accurately) than I - that the "drive" for such behavious is revealed in evolutionary terms by its function (either directly or in quite complex and subtle ways) as benefiting the genetic make-up that promotes it (or in some cases by being the accidental by-product of something else that's beneficial - that's how he sees religion, by my understanding).
Into that heady mix, add a recent article New Scientist magazine:
Two Hypotheses Emerge. Hypothesis One says that free will is an illusion, that our consciousness of free action is as illusory as our experience of rainbows as “real objects”. Hypothesis Two says that our experience of free will reflects something real in the brain mechanisms that produce and sustain consciousness.
… Hypothesis One runs dead counter to evolution and [“it is totally unlike biological evolution to give us an extremely costly phenotype… that plays no role in the survival of the organism”], Hypothesis Two is consistent with our experiences, but seems crazy. Besides, it gives us three mysteries for one: To solve the mystery of free will, you have to solve the mystery of consciousness, and you do that by relying on the mystery of quantum mechanics. Hypothesis One is consistent with our scientific view of how the world works, but we cannot live with it.
When I discussed these issues in a lecture in London, someone in the audience asked: “If Hypothesis One were demonstrated to be true, would you accept it?” Notice the form of the question: If it were demonstrated that there is no such thing as free, rational decision making, would you freely and rationally decide to accept that demonstration?

Interesting question in terms of truth - especially in a 'post-modern' climate - if a scientific "truth" is seemingly "unliveable", does that mean we have to (a) ignore it and live as if it isn't true, (b) change our entire approach to life [which seems to make more sense than the new perspective], (c) wonder whether the 'scientific' approach misses an entire body of evidence - our own self-knowledge.
Is it not possible to argue that, in scientific evidence terms, my own life-long experimental results in being 'me' should have at least some part in the discussion?
