Im still getting into the part about "absential" phenomenon. Thats his original contribution I think. Whats your thoughts on that? — schopenhauer1
Absentials are his way of talking about constraints. So I both agree with what he says, but don’t see it as original - at least within the systems science community.
The essential issue here is the difference between thinking of nature in terms of causal determinism and causal regulation.
It is is usual to imagine causality as a Newtonian system of impressed forces on material bodies. That is, a metaphysics of material/efficient cause.
A constraints-based metaphysics, like semiosis, cybernetics, hierarchy theory, etc, would instead say that nature operates on the principle of what is not forbidden is what can, and must, happen.
So reality is understood as basically free - a state of radical indeterminism or Peircean tychism. Everything tries to happen. But then global organising constraints evolve to impose top-down order on the chaos. The chaos is regulated by the new thing of form and “purpose”. A Newtonian looking world is what emerges in the limit of this natural ordering. We arrived at the “continuity” of law which is Peircean synechism.
This way of looking at things can eventually be applied rather directly to our biophysical models of life and neurobiological models of mind. That’s what I talk about all the time.
:nerd:
So in a wide variety of approaches which I endorse - Friston’s Bayesian Brain, Walter Freeman’s chaos theory, etc - consciousness has its particular character because the brain is a system for eliminating potential information states. It doesn’t compute some representation of the world so much as eliminate the near infinite variety of possible states of interpretation that could exist in regard to that world.
In that way, it is all about arriving at the particularity of a point of view - a state of pragmatic action - by constraining alway all unnecessary possibilities and thus leaving to freely happen what is left after that.
This speaks to the open character of our mental processes. The work is not to discover what is real. It is to eliminate alternatives to the degree our behaviour appears to be functional.
And that flipping of the paradigm is “absential” in that constraint is about the ability to eliminate alternatives. You arrive at counterfactual definiteness by having suppressed thoughts about everything else.
That is why attention is seen as a spotlight. As a neural process, it is literally a wave of inhibition that sweeps over the brain after about a third of a second (the p300 EEG potential) and so focuses our consciousness by suppressing every other state of interpretation we might have had.
And words function semiotically the same way. I say to you “pink elephant”. You now share the same mental image to the degree your mind can suppress other colours, other animals, indeed other objects.
But Indian or African elephant? A cartoon elephant or maybe an actual elephant got up in bright colours for a religious parade?
I didn’t say. So those become open minded degrees of freedom so far as that speech act went. And even if I kept adding constraints to be more specific, we would never expect to arrive at the same “beetle in the box”. There would always be residual indeterminism in the semiotic view.
But that is no problem for the non-Cartesian. All the (pragmatic) work that needs to be done lies on the side of the absentials. Consciousness is an example of a process in which it is the elimination of alternatives that turns the general into something specific. That is its deep “computational” logic.
And a ton of scientists get that. What is not widely understood is that this is a paradigmatic shift for science or philosophy itself. That is because most scientists just work this out within their own siloed domains.
So Deacon is good as a voice able to proclaim that general revolution. But as I say, he didn’t do enough to connect himself to the interdisciplinary community and so wasn’t regarded as a leader.
His first book felt it rather ignored the Vygotskeanism and social constructionism which was already vogue. Likewise Incomplete Nature felt as if it failed to attend to the broad changes of thought to be found in theoretical biology and neurobiology.
However that is only a mild complaint - a bit of social context for how his contributions were received.
