In reply to the discussion: Free will and consciousness [View all]cpwm17
(3,829 posts)28. Demasio apparently thinks we have free will, though he didn't explain in detail how it works,
which nobody does. He does have some of my opinions concerning the role of feelings in consciousness, but far more authoritatively than me:
page 93 in the pdf in Demasio's book: Descartes Error:

Before leaving the subject of human brain lesions, I would like
to propose that there is a particular region in the human brain
where the systems concerned with emotion/feeling, attention, and
working memory interact so intimately that they constitute the
source for the energy of both external action (movement) and internal
action (thought animation, reasoning). This fountainhead region
is the anterior cingulate cortex, another piece of the limbic system
puzzle.
My idea about this region comes from observing a group of patients
with damage in and around it. Their condition is described
best as suspended animation, mental and external-the extreme
variety of an impairment of reasoning and emotional expression...
Damage to this sector not only produces impairment
in movement, emotion, and attentiveness, but also causes a virtual
suspension of the animation of action and of thought process such
that reason is no longer viable. The story of one of my patients in
whom there was such damage gives an idea of the impairment.
The stroke suffered by this patient, whom I will call Mrs. T,
produced extensive damage to the dorsal and medial regions of the
frontal lobe in both hemispheres. She suddenly became motionless
and speechless, and she would lie in bed with her eyes open but with
a blank facial expression; I have often used the term "neutral" to
convey the equanimity-or absence-of such an expression.
Her body was no more animated than her face. She might make a
normal movement with arm and hand, to pull her bed covers for
instance, but in general, her limbs were in repose. When asked
about her situation, she usually would remain silent, although after much
coaxing she might say her name, or the names of her husband and
children, or the name of the town where she lived. But she would not
tell you about her medical history, past or present, and she could
not describe the events leading to her admission to the hospital.
There was no way of knowing, then, whether she had no recollection
of those events or whether she had a recollection but was unwilling
or unable to talk about it. She never became upset with my insistent
questioning, never showed a flicker of worry about herself or anything
else. Months later, as she gradually emerged from this state of
mutism and akinesia (lack of movement), and began to answer
questions, she would clarify the mystery of her state of mind. Contrary
to what one might have thought, her mind had not been
imprisoned in the jail of her immobility. Instead it appeared that
there had not been much mind at all, no real thinking or reasoning.
The passivity in her face and body was the appropriate reflection of
her lack of mental animation. At this later date she was certain about
not having felt anguished by the absence of communication. Nothing
had forced her not to speak her mind. Rather, as she recalled,
"I really had nothing to say."
To my eyes Mrs. T had been unemotional. To her experience, all
the while, it appears she had had no feelings. To my eyes she had not
specifically attended to the external stimuli presented to her, nor had
she attended internally to their representation or to the representation
of correlated evocations. I would say her will had been preempted,
and that seems also to have been her reflection.

They are talking about a purely voluntary decision to act. They are calling that free will.
