Two reasons, time constraints, and I didn't see any merit in your 'deconstruction.'
Of course you see no merit to it, because that’s your defensive rationalization for the fact that it must very discomfiting for you to realize that yet another one of your sources from which you carpet-bomb quotes is not a hard determinist. She’s a soft determinist — i.e., a compatibilist. She simply relabels “compatibilist free will” as “rational” behavior. That’s fine with me.
I see no merit because there was no apparent merit to be seen. Farah makes a distinction between a rational system and free will because there is a distinction to be made. A rational system doesn't work on the principle of will - nothing is willed, in the case of a brain, it functions - rationally - on the principle of neural architecture and information processing, not free will, not will, therefore a rational system, not a free will system.
Therefore, to declare actions performed by what is a rational system to be 'freely willed' is false.
What is the definition of “rational”?
agreeable to reason;
reasonable;
sensible:
a rational plan for economic development.
having or exercising reason, sound judgment, or good sense:
a calm and rational negotiator.
being in or characterized by full possession of one's reason;
sane;
lucid:
The patient appeared perfectly rational.
endowed with the faculty of reason:
rational beings.
of, relating to, or constituting reasoning powers:
the rational faculty.
All of these traits are necessary and sufficient conditions for compatibilist free will. They would be fully absent in a hard deterministic universe, which does not exist. If “falling dominoes” determinism were true (my metaphor for hard determinism) there would be no reason to expect rational behavior. There would be no reason to expect brains at all. What good is all that complex evolutionary baggage in a falling dominoes world? Although you have asserted that we are somehow different from rocks rolling mindlessly a hill, following without choice or cavil a geodesic, you have never specified how we are different. Rationality presupposes the need to think clearly, recall, foresee, and choose among available options in a way consistent with one’s perceived self-interest. None of that is possible in a falling dominoes world.
Nothing of the sort. The brain is a rational system, not due to free will, but because it has the capacity to process information and produce appropriate response, as it is evolved to do
The appropriate response is determined by an interaction of information, basically inputs, architecture and memory.
To conflate function with free will is false. To declare ' the brain is rational, therefore free will is false.
Decisions;
''There are two major ways of processing information facilitated by the human brain. I hold that all decisions are made by a risk/reward comparison of the incoming sensory information within the emotional brain (‘System 1 thinking’) rather than within the rational brain (‘System 2 thinking’). System 1, the emotional system for processing sensory information and generating responses to it according to a risk or reward weighting, is automatic, intuitive, and fast, even impulsive. System 2 is the rational, slow, and controlled system of thought, where we reason through our options. (For more about these systems of thought, see
Thinking Fast and Slow, Daniel Kahneman, 2011.)
Tucked away in the centre of the brain, System 1 monitors the environment one way or another to minimize risk to survival and maximize reward. Feedback continually updates the system about the environment. The emotional response system evaluates all the incoming sensory information, and then scores it for a ‘winner-takes-all’ competition to decide on the best response. My contention in this article is that System 1 interacting with incoming sensory information runs everything. There is no room for any homunculus here.''
The Rational Brain
''It is now clear that the two systems for decision-making in man operate so-called ‘dual process monitoring’ (see for instance De Neys and Glumicic in
Cognition Vol. 106, 2008). I see the mechanism for this dual processing being as follows. If at any time a certain threshold for alerting System 1 is not exceeded, judgement is withheld, and the more deliberative, rational System 2 may come into play. Nonetheless, the intuitive, emotional system still tends to strongly dominate. De Neys and Glumicic have found that subjects struggle to override the instinctive emotional risk/reward brain responses, since rational thought options often do not receive enough cerebral ‘weight’ to prevail over the choices of the emotional brain.''
My suggestion for how to understand that is as follows. The emotional brain always harvests the best option for response as the one having the highest risk/reward emotion score,
whether this score is derived primarily from the emotional brain, or indirectly via the rational brain. If nothing above a certain threshold is produced from the primary analysis of the incoming sensory information by the emotional system, then analysis is switched to the slower deliberations of the rational system. But – and here’s the rub – the eventual risk/reward score calculated is not estimated primarily through a ‘rational ranking’, but rather, is based on the risk/reward value of that response to the
emotional brain. Moreover, because of the way the brain works, the emotional score of rational deliberations is likely to often be less than rating from any analysis primarily through the emotional system. In effect then:
Rational options are chosen if and only if the emotion scores they evoke in the evaluation of the emotional brain are high enough to beat the scores of any more intuitive competitor responses.

Nope, not in the least. Not even a little bit. Responsibility requires a functional brain capable of making rational decisions, to be of sound mind.
Exactly! That’s not possible for a falling domino. Hence, compatibilism.
False labelling. 'Rational' does not equate to 'free will.' 'Function' does not equate to 'free will.' Compatibilists merely assert their definition and free will label.
Begging the question
Compatibilist: "free will is compatible with determinism"
Incompatibilist: "How do you know."
Compatibilist: "Because our definition says so."
Incompatibilist: "Why should I accept your definition?"
Compatibilist:"Because our definition allows free will to be compatible with determinism."
''Compatibilism is the belief that free will and determinism are compatible ideas, and that it is possible to believe both without being logically inconsistent.[1] It may, however, be more accurate to say that compatibilists define 'free will' in a way that allows it to co-exist with determinism.'' - wiki.
