Diary, “Get over it dude, why u so obsessed with Hoffman’s Case Against Reality?”

I'm happy to report that after an unexpected extension, my critical review of Donald Hoffman's "Case Against Reality" is complete.  I thought to do more by way of summary, but not getting any inspiration, so I'm done.  Perhaps in a year, providence willing, it'll be fun to revisit and see if I can write an interesting summary.  In the meantime, this will have to do.

HOFFMAN'S "CASE AGAINST REALITY," 

PLAYING BASKETBALL IN ZERO-GRAVITY, A REVIEW

Hoffman Playing Basketball in Zero-gravity Review is intended to offer solid information, food for thought, and hopeful inspiration for students concerned with American’s descent into delusional thinking.  It is set up to be easily skimmed, contains copious references to expert sources and reporting, along with a few promising gems.  

I've been challenged with the question: "Why am I so "obsessed" with Hoffman’s Case Against Reality?"

It’s a fair enough question.  Why have I spent a half year thinking about it, then nearly another half year and thousands of words dissecting Donald Hoffman’s book, The Case Against Reality, why evolution hid the truth from our eyes? 

I’ll tell you why,  

* It started with Donald Hoffman boasting that he’s doing serious solid science that is relevant to our daily lives.  When all he’s doing is sophisticated mathematical games, computer modeling, philosophizing, wrapped in just-so storytelling.  But, none of it deserves being called serious science! 

* Getting further into the book, I found my Down to Earth sensibilities and my respect for physical sciences increasingly offended by this man’s glib disregard for natural facts as scientists have refined them.

* His dismissal of physical sciences and the physicalist paradigm were as laughable, as they were irritatingly disingenuous.  

* His notion that the perceiver composes the perceived, is childish.  

After all, doesn’t light need to reflect off an object before we can perceive it?  The perceiver composes an impression of the perceived.  How does Hoffman justify such gross distortions of physical fact?

* His constant reliance on computer analogies to answer questions - is reminiscent of an evangelical’s dependence on their own Bible to make their case, such debate tactics are not acceptable for a scientist.

* His constant conflation of Objective Reality and Physical Reality, needs a spotlight.  

“Objective” being a product of our minds doing their best to keep subjective human biases out of their observation and learning process.  

Thus, science’s dependence on process and measurements; physical evidence and repeatability; facts at hand driving understanding; a community of experts always looking over each other’s shoulders; constructively learning from mistakes; demand for honesty at all levels of communication; and so on.

* His tendency to imply that Evolution has agency reveals a limited appreciation for actual “wet” evolution unfolding one day at a time, over the course of deep time.  

* In fact, turns out the only thing Hoffman knows about Evolution, is Evolutionary Game Theory.  (He's never studied actual Evolution.)  Realizing that, made Hoffman’s simplistic sweeping pronouncements regarding Evolution that much more galling.

* Then, his quantum level rhetorical fancy dancing that disingenuously conflates conclusions from atom smasher experiments with our macroscopic day to day reality, was like listening to nails being scrapped across a chalkboard.  

* He joined the chorus of talking head$, proclaiming “Space-time and Reality (as we know it) is Doomed,” a mere figment of our imagination.  Why?  Basically because their latest and greatest math breaks down, leaving them with no other conclusion.

* Then to fill in this contrived void, Donald’s imaginative storytelling comes to the rescue with Hoffmanian Conscious Agents that zip around interpreting reality for us, because the reality we think we are seeing, isn’t really there, says Professor Hoffman.  He assures us that he has the math to “prove” it.

Prof Hoffman #10b - Community - Playing Basketball In Zero-Gravity - Hoffmanian Conscious Agents (2/3)

Case Against Reality:  “I have touted the virtue of precision in a theory of consciousness. …”    (Chapter ten, ¶39)

Citizenschallenge:  Precisely modeling one’s idea is one thing, accurately reflecting Earth, evolution, human nature, is another.  

Hoffman’s Case Against Reality is a philosophical/religious thesis, removed from actual nature and physical reality.  Hoffmanian Conscious Agents offer nothing to observe, and nothing that can ever be tested, beyond computer games.  

The book was a disappointment with little to enhance current neurological, physical, or psychological understanding.  It is marketable intellectual entertainment for the sci-fi, woo loving crowd.  

To me, it's a splendid example of the sort of fame and fortune seeking hubristic follies that helped create today’s willfully ignorant populous, which in turn enabled the current political degeneration, along with all its horrendous cascading consequences of late.

I’m trying hard to enunciate my thoughts in as coherent and concise a manner as I can.  This is because I want to be one of the many many ‘Children Of The Intellectual Enlightenment' who are needed to stand up for rational sober science; people willing to advocate for respect of the reality of our three dimensions and time; for the fact that matter is substantial and can be measured with astounding accuracy and repeatedly, etc., etc.  That serious good-faith science deserves to be respected and trusted.  

I’m just an attentive life long spectator, self-schooled and nearing my end, knowing a fraction of what serious students know.  Where are you??   This is my workbook and you are welcome to use any of it, respecting original sources.  I'm hoping some might find a little inspiration.  

Engage to do something to confront the creeping disconnect from Physical Reality and contempt for science that’s infecting so many people out there.  

Show ‘em you have Soul, the kind that emerges out of grasping deep time and Earth’s Evolution through the lens of science.  

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Donald Hoffman tells us: 

“Conscious realism is a non-physicalist monism.” 

 Lets unpack that:

In ontology and the philosophy of mind, a non-physical entity is a spirit or being that exists outside physical reality. Their existence divides the philosophical school of physicalism from the schools of idealism and dualism; with the latter schools holding that they can exist and the former holding that they cannot. If one posits that non-physical entities can exist, there exist further debates as to their inherent natures and their position relative to physical entities. [WIKI]   It get's over complicated, see here.

In other words, by his own definitions Hoffman’s “Case Against Reality” is a non-physical “reality”.  Namely, an abstract meta-physical idea and beyond the reach of empirical science.

Hoffman claims his mathematical rigor makes it science.  But, he forgets that serious science (as opposed to science fiction) also requires observation, measurement, evidence and facts.  

Rigorous mathematics without such physical touchstones, amounts to a self-indulgent head-game, one that has more in common with religious desires, than natural sciences.

chapter 10b, Community: The Network of Conscious Agents

Prof Hoffman #10a - Community - Playing Basketball In Zero-Gravity - The Network of Conscious Agents (1/3)

Cc:   Consciousness is an emergent property of biological complexity.

DH:  “The notion of a conscious agent is based on intuitions that are widely shared.  It must, however, be made precise and then endure the rough and tumble of science.”     (¶9)

Hoffman hasn’t produced anything tangible.  A fine tuned ‘theorem’ proven by mathematics within an idealized computer model universe, isn’t tangible.

Hoffman’s notions are the stuff of rough and tumble philosophical debates, not serious scientific inquiry.   That is, observing, measuring and learning about tangible stuff.

DH:  “…Evolution shaped our perception to hide the truth and to guide adaptive behavior.   (¶3) 

DH  : ”A new theory is required, in which spacetime, objects, their properties, and their fiction of cause and effect,…”   (¶4)

Besides a tendency to imbue Evolution with agency, Hoffman wants us to believe Conscious Agents act from outside.  

Where do Hoffmanian Conscious Agents originate?  How would they have been created?  Have they ever been observed?  Are they God’s twinkle dust holding everything together?  

Evolution isn’t a thing, or a program, it’s a label we put on accumulating change over time.

chapter 10a, Community: The Network of Conscious Agents

I invite you to consider a different kind of “Conscious Agents.”

If organisms were to survive upon this four dimensional Earth they needed to perceive and act.  Sense organs needed to be invented or nothing would have happened on Earth.  

Furthermore, those organs needed to communicate with something; and that something needed to decode the incoming data; that data needed to be communicated to higher authorities for processing; decision making; and inducing action.

“Conscious agents” are the information the brain sends forth to blossom into the thoughts within our mind. 

A neuroscientist would correct me, by telling me about “neural correlates of consciousness,” then perhaps they’d point out the recent discovery of three super neurons that cradle a mouse’s mammalian brain, along with the implications and how that’s impacting the direction of current research.

Prof Hoffman #9 - Scrutiny - Playing Basketball In Zero-Gravity - Needs, in life and business

Hoffman starts chapter nine by repeating his drill:

DH:  “Our sense forage for fitness, not truth.  They dispatch news about fitness payoffs: how to find them, get them, and keep them.

Keep in mind, this according to a theorem that plays out in an idealized mathematical universe of Hoffman’s design.  Not in our real universe ! ! !

DH:  “Despite their focus on fitness our senses confront a tsunami of information.  …”  (¶1-2)

All that Hoffman reduces to simplistic four-square games with ill defined terms such as “fitness” - “truth” - “hawk” - “dove” - terms that are fundamentally meaningless when it comes to actual evolution on Earth with it’s constant tsunami of information coming at us.

 

A review of Donald Hoffman’s, Case Against Reality, chapter 9, Scrutiny,

You Get What You Need, in Both LIfe and Business 

As I’ve worked on this project searching out respectable information and following leads.  I’ve been amazed by how much presence Hoffman’s Case Against Reality has attainted on the internet.  He truly is a marketing genius.

Seems that many people think this Case Against Reality is fascinating.  Time is doomed.  Man, how cool is that?!    

Me, I’m left wondering, what drives such a desire for this sort of vacuous escapism?  

DH:  “For those readers interested in marketing and business, this idea applies to visual advertising.  The goal of successful advertising is not merely, and sometimes not even, to present important facts.  It is to craft visual message that rivets the foraging eye of the typical shopper. …”   (¶12)

Prof Hoffman #8 - Polychromy - Playing Basketball In Zero-Gravity - Mutations of an Interface

DH:  “Color can speak volumes. … Color is a window into fitness - also a jailhouse. … Try to imagine a color you’ve never seen.  Can’t do it. … Color… like perception, is both window and prison.”   (¶1)

Polychromy = “the art of painting in several colors, especially as applied to ancient pottery, …”

We could also say that our bodies are the prison of our mind.  If you really wanted to look at it that way.  But, what’s it get you?  Beyond a reflection into your own psyche?

A review of Donald Hoffman’s, Case Against Reality, 

Chapter 8, Polychromy - Mutations of an Interface

DH:  “As a window on fitness color is not flawless, just adequate to guide our actions that keep us alive long enough to reproduce.  Color, like each of our perception, compresses the complexities of fitness payoffs to bare essentials.”   (¶2)

What gives Hoffman the right to expect some subjective idealized flawlessness from nature?  Seems a bit hubristic to me.

Sure color perception is an important element, among many important sense “elements,” none of them perfect in the best of times, all vulnerable to a galaxy of pathologies and quirks.  Such is life.  That’s why luck often matters as much as fitness.

The fundamental problem with Hoffman’s narrative is that he keeps blaming the perceived object for the quirks and short comings of the perceiving instrument.  It’s silly.

DH:  “(The human eye has 7 million cones and 120 million rods, each carrying compressed information.  The circuitry of the eye then squashes this down to 1 million signal and forwards it to the brain, which must correct errors and decode actionable messages about fitness.”   (¶8)

Thus optical illusions happens. I’m going to skip paragraphs worth of Hoffman’s tour through optics trivia.  I’ll share trustworthy authoritative sources and let them explain the details without Hoffman’s tactical omissions.

Prof Hoffman #7 - Virtuality - Playing Basketball In Zero-Gravity - Inflating a Holoworld

In chapter 7 of Case Against Reality, Hoffman’s “spacetime is doomed” mantra starts sounding like a hypnotist's spell, as reality fades from view.  Here we read more fascinating stories that reveal slivers of actual physics, but then contain too many important omissions to be of any constructive help.  

One way Hoffman misrepresents facts and twists conclusions is by anthropomorphizing the results and implications of quantum experiments and theory, all the while ignoring the profound difference between quantum scale experiments, and our macroscopic physical reality. 

Or, for that matter, you’ll not hear Hoffman acknowledge the profound difference between his mathematical models of idealized universes and our actual ever evolving universal physical reality.  

Of course bias comes into it.

some have the luxury of sitting back and dreaming,

Others best take reality as a given and stay focused,

and get on with it.

As a simple hands on working man, trying to follow through on Hoffman’s trains of logic leaves me overwhelmed time after time.  I don’t kid myself, with my middling layperson understanding of physics, I’m in no position to offer lectures or corrections to Hoffman’s details, nor is that my intent.  

Heck, I’ve had to do a lot of searching and additional reading these past weeks and again wrestling with this chapter, trying to grasp the various philosophical strands running through it and trying to wrap my head around the heady pipe dreams of these creative theorists.

My intention is to get through Hoffman’s book then to offer a saner down to Earth alternative.  An evolutionary perspective of our Earth and our human relationship with this physical reality we are embedded within.  Sans the religious baggage Hoffman’s theorem carries, stay tuned for more on that. 

I compensate for my mediocre mind by doing homework and knowing how to check out claims and weigh evidence.  For this chapter I’ve blown my deadline and spend a good deal of time learning more about what knowledgeable authorities have to explain.  I’ll be sharing highlights throughout this review.

chapter 7, Virtuality - Inflating a Holoworld

DH:  “… But here, where I don’t expect it, science injects a profound mystery: we still don’t understand “now” and “there”.  That is, we don’t understand time and space - length, width, and depth - which we take for granted, which are woven into the very fabric of our daily perceptions, and which we assume are a true and reliable guide to physical reality.”   (¶2)
