J. R. Molloy <jr@shasta.com> 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.
