Analytic Idealism in a Nutshell: A straightforward summary of the 21st century’s only plausible metaphysics by Bernardo KastrupMy rating: 5 of 5 stars
Kastrup is brilliant, and this book provides an excellent exposition of the metaphysics behind his cosmology. His theorizing usefully dispatches several of the nuttier directions that dogmatic physicalism has taken. Along the way, he provides an excellent elucidation of what information theory is and what it isn't. I've been craving that since forever. Not to mention putting A.I. in its place.
The trouble is that although he claims Occam’s Razor as his guide, he introduces still more needless complexity with his flip-flop from physical to mental; thinking that he’s reduced complexity by claiming that all of reality might reduce to a single principle, which is mind.
I have more than a little sympathy for this maneuver, but in fact Kastrup glides past a more basic distinction between perceptual and conceptual reality. By replacing the substance of physics with mind-only, Analytic Idealism actually re-enters woo-woo mysticism rather than to escape from it.
In the end, Kastrup has conducted a sleight-of-mind 'against' himself; he fools himself in almost the way that he accuses physicalist scientists of doing.
Kastrup is right about many things, and his insights have enabled him to challenge accurately many of the stranger cosmologies of his physicalist colleagues. But that doesn't quite stop him from his own weird conclusions.
In brief, Kastrup substitutes an inside/outside duality for the now antique mind/body duality for which Descartes generally receives credit or blame, depending on one's disposition. Mind/body maps to concept/percept while inside/outside creates an entirely unnecessary complication about that aspect of mind which cannot consistently be claimed to be inside, and that which is demonstrably outside.
Kastrup’s usage of his newer term "alter" to describe our individuated interiority is useful, though not meaningfully different from Descartes' usage for mind once inside and outside are introduced.
In Kastrup’s “analytic idealism,” alters exist in a field of “subjectivity,” built on the analog of a possible grand unification theory for quantum electrodynamics, where there would be a single quantum field upon which all that we perceive as physical has no separate ‘substance’ from the field. A wave is an action on water and is nothing without the water. It has no substance, and is the very meaning of abstraction once we call it into being. Abstraction is a conceptual maneuver whereby concepts are taken from physical reality.
No actual circle exists in nature, any more than numbers can be imposed there without some degree of abstraction. But the concept of the circle and the power of numbers to help with prediction and therefore with understanding are both undeniable. Sure, a circle is the stuff of mind, while we may perceive only approximations. It’s the matching of percept with concept which composes understanding.
While there may not be any actual and perfect circles in what I would still call the physical world – the world of substance – there are plenty of structures whose description is equivalent to their actuality. Molecules, for instance, whose structure is identical from one to the next such that each is individually indistinguishable. But they do have a describable form.
‘Field of subjectivity’ is only meaninglessly different from ‘field of objectivity.’ The meaningful distinction is between conceptual and perceptual reality.
As do many who descend from the world of information technology, and in his case also the kind of Quantum Electro Dynamics which energizes CERN, where he once worked, Kastrup uses the inaccessibility of personal thoughts to others/outsiders – the secrecy of our thoughts and feelings – to prove his inside/outside distinction.
He then goes further, and for me beyond the pale, to replace the sensible apprehension of the boundary of skin with a fairly, to me, specious metaphor of a “dashboard.” In many ways - and this is surprising to me - Kastrup is himself stuck in the Western set of imperatives as much as are those physicalists that he ridicules.
"Alter" is his metaphor for how individuals - chips off the cosmic mind of analytic idealism - are individuated. We are likened to the seemingly separate selves of those who suffer dissociative identity disorder, or what used to be called multiple personality disorder.
One of the weirdest of Kastrup's moves is that he posits a reality apart from perceptual reality (as conventionally considered) that is more real than what we perceive. I suppose the metaphor is that the physically real is composed of unperceivable parts; subatomic particles, in a vast emptiness, say, pervaded only by a quantum field.
According to him, those “particles” are actually eddies in the subjective field without substance of their own. Quantum fields may be more both/and than he thinks though, which might even scotch the dream of completion for a Grand Universal Theorem. Not every literate human culture is quite so obsessed as the West is with history as unitary progress toward completion.
He attributes our misperception - our inability to perceive actual reality - to the perceiver inside our perceptual apparatus having only a dashboard by means of which to perceive. We can’t see reality in itself. Well, of course we can’t. Reality as we perceive it is also composed with concepts, which are mind extended into matter.
But Kastrup then goes so far as to say that the things of our lived experience from behind our dashboard wouldn't exist without someone there to perceive them. They exist in mind and not in matter, remember. He thus reintroduces the gracefully moribund mind inside the mind corroborating sensory inputs. The mind behind the inner screen is a free floating "alter." A mind inside a mind in infinite regress.
Abstraction is real. The physical is real. One is conceptual while the other is perceptual. Putting both on the same side in a universal field of subjectivity is where Kastrup stops following the principle of Occam’s razor. Analytic idealism is far more complex than a metaphysics allowing for both conceptual and perceptual reality; both mind and physical stuff.
In my usage, the only meaning for interiority is that there must be a physical divider for perception to occur. That's not the same as to say that there must be a perceiver "inside" or behind some screen. There is no real locus for the self inside of mind. Kastrup’s replacement of skin with screen, and mind with alter recreates a superfluous and unnecessary confusion.
Perception happens to a body as divided from the rest of reality by a skin and its organic involutions which form our perceptual organs. The mind of the perceiver has never been confined there, inside our skin nor certainly inside our skull. Kastrup and I seem to agree on this.
As do most scientific thinkers, Kastrup - who talks about emotion more than most scientists do, and certainly more than most devoted materialists ever would - still relegates emotion to being epiphenomenal to consciousness. He often conflates thoughts and feelings as things without extension. He claims to deproblematize the puzzle of consciousness by positing that mind is the whole shebang. So, no problem with consciousness being transformed or transmuted out of physical stuff!
But really, consciousness is just the apprehension of both conceptual and perceptual reality. A lizard knows a hawk when it sees one. Evolution adds the quickening of emotion to the apprehension of a hawk to short-cut conscious thought.
At some level higher than a lizard, something like re-cognition occurs, bringing choice along with reaction.
I confess that I don’t see the need for the usage of “qualia” that many philosophers see. Just because colors and flavors don’t exist in the thing itself, the fact that such so-called qualia are almost universally shared should be sufficient to put them on the perceptual side of things. Niggling about the marginal cases seems not much different from mistaking distortions for wholesale misperception, as Kastrup tends to do.
Those perceptions assigned to the category of qualia are rather more complex than simpler perceptions. I would say that the proof for their objective existence is simply that we can talk about them. And animals respond to qualia much further “down” the line.
I would say that concepts exist outside the individual mind, and that, therefore, emotion is fundamental and even primordial. Indeed, mind cannot be described without emotion. Any mind is as much about emotion as it is about cognition. I’ll even grant that Kastrup might agree with this.
But emotion requires at least as much definition as physical forces do. Here’s my radical maneuver: emotion is both real and as outside of mind as perception is.
In my usage, emotion is rather more like the false definition of gravity as a simultaneous force acting at a distance. That sort of physical simultaneity is better defined by a shared 'curvature' of space-time, as Kastrup urges us to understand. Emotion is defined by actual simultaneity without any physical force involved. Emotion is engendered by conceptual/mental and not perceptual/material movement. Emotion involves no physical force but is engendered by the matching of concept with percept, the apprehension of new concepts or the transformation of old ones. It is not a process which can exist within an asocial individual. For humans, emotion takes as much learning as does cognition. But unlike perception, emotion is felt directly by the mind. If mind is outside the skin, then so is emotion.
And furthermore, morality is no more a part of Kastrup's purportedly comprehensive analytical idealism than it is a part of physicalism. Kastrup’s ethics might be something like “we have to keep contributing to the cosmic mind.” In the same way, a physicalist might use the imperative to understand as the highest purpose for humanity.
But in fact, conscience is more a matter of fellow feeling. For humans, the recognition which engages conscience is enhanced by the highly individualized nature of faces and voices and stature and skin coloring.
Being me is still about outside and inside, and a bat or a human only knows what it's like to be me from the outside. And yes, I mean that I don't know what it's like to be me from the inside. I can't know myself without you who help me to know myself. Cogito ergo sum is nonsense, as we all know. My good friends know my thoughts much better than I do. That sometimes hurts. Don’t we hide from ourselves as much as we have secrets? And having secrets doesn’t indicate a thing about the privacy or insidishness of our mind. Sure, we put some of our thoughts behind a blind, and sometimes we blind even ourselves.
To repeat myself again and again, I make my claim for his fooling himself in part because of his strange - to me - reliance on the hackneyed usage of an instrument panel to describe our distance from understanding or even describing the world as it fully is. Like a computer screen and its icons as related to the workings of the actual computer, another of the metaphors he uses, we only know what is presented. Trying to interact directly with the inners of a computer could only get in the way of its usefulness. This "interface" between inside and outside is identical, I would say, to the dualistic distinction between mind and body, and equally useless as an explainer of anything.
His screen metaphor confuses our perpetual shortfall from full understanding with a perceptual shortfall from full seeing. Indeed, I don't believe any adequate description for 'understanding' exists in his arguments.
Sure, there is more complexity to the world than what we can know, but almost none of this regards what most of us will continue to call the physical world. The contours of the physical world are as real as the conceptual relations beneath or behind or within those contours. Those interior contours of reality are, yes, mental, but as with the surfaces, they are the same to every understander. Instruments on a panel may refine our perception, but they almost never change its outlines.
The complexity we miss from behind our screens is really mostly social and intellectual. The sort of complexity that it's always hard to understand without actual engagement. It is indeed our physicalist researches which have, by way of measurement and calculation, enabled us to refine our understanding according to the materialist scientific method, to the extreme that we have.
Of course, there is complexity to the physical world which we cannot see directly. But we can certainly understand it by way of instruments connected to a dashboard.
Sure, we are limited in our perceptions by the fact that we don't see all frequencies of light, nor hear all frequencies of sound, nor taste all that might be tasted. But when we do extend our perceptions by use of those instruments which compose his metaphor, we have no reason to expect that the invisible - meaning not fully perceived - world would be drastically altered [sic] from that part of it which we do perceive.
And to perceive is not to understand. Instrumentation and numbers enable a deepening of our understanding of the physical world. There is no reason to suspect that the physical world is substantially different or other from what we perceive directly. And you will never know me by my guts. Do we see through or with a telescope? Our instruments allow us to make better predictions. The best part is that quantum physics puts a stop to our dreams of complete understanding. We cannot and do not stand outside the real world.
Understanding is a match between conceptual and perceptual reality. As regards the material world, that would involve the ability to predict behaviors based on an understanding of properties. Emotional reality depends, differently, on mutuality and simultaneity of a sort which can't exist in the physical world.
For a conscious agent having free will, emotion impels both physical motion away or against or toward at the same time that it instigates a mental quest for understanding. It is telling that Kastrup is involved in developing hardware for Artificial Intelligence. But, mirabile dictu, he is not so mystified by it as are those whose most precious dream is to get fabulously rich and powerful off it. Kastrup’s explanation about what AI is and isn’t is just as good and clear as is his explication of information theory.
If mind is all, then there can be no fundamental difference in mind depending on its substrate. Kastrup avoids the trap that the brain is the house of the mind. It's not just that AI has a difficult time with emotion. It's that the on/off nature of silicon logic gates divides such quasi-thinking from the extension that living mind has to the universe all around. Kastrup gives us this and then takes it away with his dashboard.
As the mind researcher Riccardo Manzotti urges us to understand, our memories are not contained in our brains, which instead loops our actual perceptions of actual things. Our memories are all around us. Visit a former habitation if you can find one that hasn't changed too drastically, and feel the memories rush in. Our brain generalizes from multiple perceptions to form concepts. Those concepts are also out in the world. We prove this easily by the languages which create our social being. We share conceptual reality.
It is specifically this conceptual reality which mind "imposes" on what we perceive. We organize the world into lions and tigers and bears, never mind that these are not always so distinct as our mind would like them. Those objects still exist if conceived differently by others. Sure, there is some raw stuff not yet conceptualized. But the reality that we've already conceived is as real as real can be, despite Kastrup's protestation that evolution requires distortion of our perception. Distortion does not make the world that we perceive unreal. Distortion is correctable.
Emotion is as real and external to us as is measurable and detectable physical reality. Indeed, the reality of emotion falls out naturally from Kastrup’s definition of reality as cognition. Mind before matter, as it were. And emotion before cognition.
I do think his discarding of matter complicates rather than simplifies his cosmology. Of course, matter is something, but it is not everything. Neither is mind. Contrasting with his usage for the parsimony of Occam's razor, I would say that to maintain the yin/yang of both mind and matter is the parsimonious course. Get rid of static outside/inside. Reality moves.
As illustration, consider that evolution has a direction which is, in rough terms, opposite to the direction of physical entropy. Indeed I would say that the physical enactment of time's arrow is defined by that interplay, and I would call the direction of life's evolution something akin to love or eros (for the materialists).
On-line, Kastrup has described his own uncanny experiences, which are nothing other than meaningful coincidence, which probably can't be proven or disproven, since it's only meaningful to those who find it so. But Kastrup has described his openness to such happenings after being convinced by his own analytic idealism. Likewise, evolution depends on random mutations - on happenstance - which is no longer so meaningless when taken in the aggregate.
Apart from the metering of entropy, material science has no explanation for time's arrow. And yet for all his analytical idealism, Kastrup still treats time in the way that historians do, and supposes a before and after for everything. Having experienced death a few times, I have the revelation that before and after collapse into a lifetime fully present. Kind of the way the Big Bang might or should be conceptualized, instead of trying to measure its distance from now across time. I would love to disabuse Kastrup of his fear of death.
Love is indeed the hardest guide for humans to follow, though most of us know it easily enough in opposition to, say, hate. From there, everything about morality can be built, no man-made dictates from a man-made God required. However, why not call the non-alterial [!!] all of analytic idealism - the cosmic mentation, if you will - why not call that God? What else to call cosmic mind? It does remain other to us, and always shall be. And God won’t be conscious until or unless there’s another cosmos. Ha! Bernardo and I agree!
Is it any wonder now that the world is in the thrall of conscienceless individuals? These are people without fellow-feeling, sometimes believing that they are following God’s dictates, and sometimes obeying the false consciousness of transactional materialism.
