J. R. Molloy <firstname.lastname@example.org> provided us with some interesting text by Francis Crick:

Here is where I get a bit confused.
Didn't Crick just get done explaining that we are aware of the decisions to act but not aware of the computations which lead to the decisions to act? And consequently we confabulate to make meaning out of it all and reassure ourselves of our self-determination? There is only process and outcome. We observe the outcome and convince ourselves it is the product of our will.
Why then would he suddenly start talking about where in the brain Free Will is located? Doesn't he mean "where the computations are?"
Anyway, it's long been disconcerting to me that so much of my behavior is not actually under my control. This is one of the reasons I'm a transhumanist. Transhumanism to me is all about attaining Free Will and potentiating our intelligence. It may be the most important human limitation to overcome.
