More Anthropic Physics?

Picture this:

cosmicdarkagesillustration

The left hand end represents what can be “seen” directly from earth, relatively local and recent in red-shift terms. Look out any window. Out into space, backwards in time.

CMBR, (Cosmic Microwave “Background” Radiation) at the right end, represents the iconic echoes of the original big-bang in microwave-visible structures. So iconic, the little strip of the “heat map” already carries the whole story. Verily, a meme.

Blog post and original paper, both by  Stacy McGaugh.

Blog Post on Tritonstation:
“The next cosmic frontier: 21cm absorption at high redshift.“

Paper on Arxiv:
“Predictions for the sky-averaged depth of the 21cm absorption signal at high redshift in cosmologies with and without non-baryonic cold dark matter.“

So much cosmology suffers from doubts of can it really be science? – regarding the tenuous and indirect nature of any “empirical” evidence to support speculative interpretations of what little can be observed, if anything. The CMBR heat-map originally created a stir because it appeared to show structure (very early in the history of the universe) in which our perspective, (as human observers on earth today) was reflected in the patterns of those structures.

That ought to be impossible. It suggests Copernicus was right, we, the earth, our solar system, really are somehow the centre of the universe.

To paraphrase any number of cosmologists at the time.

Of course the smart-money, philosophy, was always on the side of some observer effect. That our would-be objective model of physics is after all a human construct, probably with our perspective as observer (ie model-builder) built into the story. It’s only natural. Humans are – obviously – the center of physics. We built this city. Science can’t be as entirely objective as it would like to be. Physics is anthropic.

If that was literally true of the cosmos, not just our model of it, there is a good deal of supernatural explanation to be denied. And denial is what bad physicists did. Physics is political.

Good physicists keep looking, theoretically and empirically. Theoretically you can make a teleological (information / entropy / patterns) argument that intelligent life is in some sense an end – an objective – of cosmic evolution. Central in some grand scheme of things, even if a geometric cosmic centre in space-time is a moot concept. More denial, obviously, from bad physicists. Good theoretical physicists, those that recognise the metaphysical dependencies in their natural philosophy, are working on many fronts to explain what is going on. Many philosophers too.

But the science of this story still depends on some good physicists finding some empirical evidence to join up these extremes of cosmic evolution with some middle-ground.

The search for gravitational waves was part of that story. But when stakes are so high – the entire supernatural vs objectivity confusion – agendas are (almost) inevitably politically motivated to deny one side of the argument. As Brandon Carter pointed out many years ago – in earlier “fine-tuning” debates, long before the CMBR observations – the mere suggestion of the word Anthropic sends most physicist screaming for the hills in denial of any such possibility as a matter of policy. People stop listening.

Which is where the latest work by Stacy McGaugh (with original linked at the top) comes in. Good news is – whatever the technical, empirical detail and the statistical interpretations (eg in the significance of very small differences between mind-bogglingly large numbers for example), not to mention the physics itself- human perceptions of the boundaries of possibility are acknowledged rather than denied.

“Wonderfully, the atomic physics of the 21cm transition is such that it couples to both the radiation and gas temperatures in a way that matters in the early universe. [Me neither, but.] It didn’t have to be that way — most transitions don’t [*]. Perhaps this is fodder for people who worry that the physics of our universe is fine-tuned.”

“In the meantime, I think we’re obliged to take their result seriously, and not just hope it goes away (which seems to be the first reaction to the impossible).”

Worth a read. Don’t worry, be happy. Keep calm and carry on. Onward and upward.

Phase-transitions – really are part of this “fluid” picture.]

Poisoning the Environment

Just a quickie, a hold-that-thought post (prompted by the US Glyphosate court verdict, but not specifically about that):

Two things – herbicides and pesticides, and controlling vermin.

Humans are an intelligent evolved species. We didn’t get where we are by allowing the environment to take over our lives – we legitimately manage our environment in enlightened ways that secure the future of humanity.

Rats we control – scare away from habitation, kill as humanely as we can if we have to. Except for domesticated individuals we don’t invite rat tribes to share our space. Crows we control, they outcompete for food supplies and steal eggs from physically weaker species. Moles we control, and so on.

Ditto, we control invertebrate pests and vigorous weeds in agriculture and domestic gardening. We do it with as much humanity and consideration for unintended consequences as we can, but we do it.

But we’ve controlled ourselves down to barely sustainable levels.

Whether it’s controlling crows on grouse-moors or moorland inhabited by Curlew (@BBCR4Today, today) – takes some ingenuity, not to disturb other breeding species and the environment more generally. In our domestic garden context – judicious scaring and discouraging seems to work, but only just. It is ideological to defend crows rights as somehow sacrosanct over broader environmental care.

Neonicotinoids have a bad rap for poisoning bees and other pollinating insects beyond originally intended environmental control – obviously before that the likes of DDT were the villain.

As herbicides, strong poisons used to be the norm 2-4-DP, Paraquat, Chlorate, you name it. These days domestically at least – there is only one game in town – Glyphosate, whether it’s branded RoundUp or not, made by Monsanto or not – and Monsanto are part of Bayer now anyway.

Neonics and Glyphosate have their own unintended consequences – we need to care about that. But the fact is these “modern” control chemicals are much less effective that older blunter instruments AND with more pervasive negative consequences.

Safer to use simple strong poisons – oxidising agents and other crude methods – that degrade into safer side-products locally, than persistent and pervasive complex chemicals. (I now Glyphosate degrades – but it’s so safe it’s useless for its intended purpose except when used on an industrial scale – counter-intuitive unintended consequence is the drive for greater use(!) – eg for crop desiccation as well as herbicidal use. Main risks are high-dose human exposure rather than environmental anyway.)

We’re overly mesmerised by proven issues than unknown risks, and defeating the primary human flourishing objectives. (Taleb is particularly strong on “fat-tail” risks, but has a particular anti-Monsanto shills agenda, and I have no doubt “their” chemists have over-stepped ethical boundaries in defence of interests, but …)

KISS – otherwise we’re just kicking environmental risks into the long grass.

[Post Note: Still just a holding post,
but picked this up from conspiracy-debunker Myles Power:

I like to think he’s right, but I have no evidence review of my own. Old people dying of cancer has to be the norm, so for me it’s about statistical significance vs the options, and there aren’t many options if we ban all human deployed poisons. Back to my main argument.]

[Ditto – Climate Change vs “Denial” – proper scepticism involves understanding risk tails. Simply invoking “precautionary principle” when dealing with the “unpredictable” is as reckless as ignoring risk. Taking risks is what humans do.]

The Boris Burqa Brouhaha

I feel the need to comment on the recent Boris bollox since it conflates several topics I’ve written about at length before. This tweet from @Whoozley sets the agenda fair enough:

“Banning” is generally wrong way to address any complex topic with divided opinions, and to be fair, that IS Boris’ substantive point.

Attacking the individual is generally wrong too – but that depends on freedoms and motivations (see complex). Attacking an issue by “mocking” archetype individuals – letter-boxes and bank-robbers – is kinda OK if you are the court-jester but not if you expect to be taken seriously as a politician. Being provocative in order to start a debate can be OK too – but this debate has already started. 9/11 provocative enough for you? What we need now are constructive contributions. It’s not a matter of “shutting down debate”, it’s a matter of proceeding responsibly. The “right to offend” comes with context dependent responsibilities. Boris has a track record when it comes to rhetorical irresponsibility and opportunism – it is for this he should be damned. (And of course with Boris and 2018’s populism, you could go well beyond this in to deliberate divisive agendas (*).)

Of course, the right to choose what to wear is not absolutely free in general. Muslim or not we have social mores on what is appropriate to wear / expose, where and when, body and face. See modesty more generally – always the elephant in the room in these debates. (And think bum-cracks and lard-arsed leggings, you name it. When it comes to freedom, the sky’s the limit, but not always appropriate. “Too much information” generally covers it.)

That’s all pretty general – appropriateness – true of so many issues.

It’s the final point that adds a distinct additional level of complexity here. That is the extent to which wearing Muslim body coverings is in fact a choice for the woman concerned. Before we even get to questions of religion and patriarchy, this is as complex as multiculturalism itself. The extent to which cultural & religious differences – symbols and practice – should be tolerated, supported, encouraged, moderated, segregated, integrated, etc, etc. Bigotry city for the overly simplistic.

As @Whoozley says, it is – “well complicated“.

[Post Note: And to illustrate the point …

Yes, Atkinson’s relative silence is significant. Joke or otherwise context matters. Baddiel gets it – see the Dankula case. Atkinson is however wrong with “you should only apologise for a bad joke”. We can’t all be court-jester. Your humour can be as offensive and edgy as you like, so long as it’s good – and so long as you are the court-jester. Come in Frankie Boyle. Come in Rod Liddle.

Boris (like Corbyn) is cynically emulating Trump no doubt encouraged by Bannon. “Whilst masquerading as a serious politician, I can break all the rules and take you all for fools.” That is the real offense. Rules are for the guidance of wise men and keeping the village idiot in their place. Political correctness is properly about how you choose to use language in politics, not about the topics you’re allowed to mention. It’s the choices you make that tell us about your intentions, not the words. The fact we can all play the fool, doesn’t mean we should. That’s insanity.

Oh and one more:

So what’s the fuss? The burqa? – see “it’s complicated”.]

Psybertron2020 – a Sustainable Future

Psybertron is entering a phase of housekeeping and consolidation ready for a sustainable future. Watch this space for updates on live and archive links.

Housekeeping Tip

Broken links are a standard feature of long-standing web-pages, like mine. The internet evolves even if nothing changes with the organisation and addressing of your own site. And in fact I have a major house-keep in progress.

One feature of WordPress I covet is a search and replace algorithm that would permit human-mediated bulk-edit of changed links. Seems fixing links is still an entirely manual exercise.

This Google feature helps find broken links, but fixing is one long manual chore, I’ve done sporadically in the past, but impossible to complete.

Simply organising found broken links even by simple alpha-numeric order would allow batch selection for a “replace” string. Come on guys.

Krauss Catch-up

Wouldn’t normally share personal gossip, not even concerning people whose professional work I have little respect for, but I felt it necessary to add a footnote to some remarks I had already made in a post from 2014 concerning the recent 2018 news about Larry Krauss.

Maslow, Pirsig and Foucault Catch-up

Was prompted to revisit a couple of older posts on Abraham Maslow after someone asked me to explain a reference this morning.

The one I shared was this one: “Motivation 3.0 – Pink Does Maslow“.

Then I noticed one of my earliest Maslow posts was way back in 2002 “Maslow’s Hierarchy of Needs” and that I had already added up-front links to two better later posts, the one above from 2013 and also “The Meme of Maslow’s Mojo” from 2011.

Strangely, the reason Maslow was in my mind was another query in recent days – was it Bruce or Eddo? – asking if I’d noticed parallel’s between Maslow and Robert Pirsig’s evolutionary levels. Of course I had, plenty of times, but only noticed this morning that I’d made that explicit in the 2002 post above.

“I’ve [already] made made countless references to Maslow ever since I noticed that Pirsig’s levels of “value” (absolute quality or goodness) appeared to mirror [Maslow’s hierarchy of needs.]” (2002)

If that’s not fascinating enough, imagine my surprise at this:

“Pirsig and Foucault seem to say [Maslow’s levels] represent something pretty fundamental about human social organisation and values.” (2002)

Pirsig, Maslow and Foucault already in 2002. I spent quite a bit of this last year joining up some Foucault dots in some other new correspondence on Pirsig. I’ll need to go back to see where I made the original Pirsig-Foucault levels connection. (And here it is, reading Foucault’s “Les Mots et Les Choses” in Aug / Sept 2002.) (Plus panrelationalism, threes / triads / triples / onion-skins, Wheeler on semantics underlying physics … it’s all in there on Foucault.)

I need to stop reading and start writing!

=====

[Post Note: Ikigai – Similar set of concerns from the individual looking out rather than what interaction with the world gives to the individual – another representation of the content of Maslow:

Strictly only 3-way – anyone on a mission to love stuff the world doesn’t need is surely a twisted psychopath? (Except with a narrow utilitarian idea of “need”.) Or if you prefer, what the world needs …. is love.]

Changing Your Mind

A pet hate of mine is “rational” people who see the point of a rational argument as being to change someone’s mind, to convince someone of something.

A bonkers idea at any time, not to mention a complete waste of time if you think the person you are trying to convince isn’t being rational anyway. It’s a bonkers idea in general because only you can change your mind, and that’s true of anyone else. You can’t change my mind.

The point of dialogue is to learn. And to be “rational”, the dialogue can be any mix of the objectively logical and subjectively rhetorical as long as it is directed in good faith. The point is to understand better what you understand and believe. And that’s true of anyone else. When it’s not, you and/or they are not actually engaging in the dialogue, you’re not even at first-base yet. All bets are off.

Once that dialogue is engaged, minds evolve. That’s how minds change. They’re not changed by someone else.

There are only two situations where point-scoring critical debates that win and lose, making and refuting points, have any place.

Where both parties are already – in good faith – inside a control volume where it is the objective and mathematical logic that is being validated. Even in what look like academic scientific arguments, neither party will  remain confined to that control volume throughout. Everyone has an agenda and interests. Their skin may be in a different games.

Where the belief or opinion makes sense to be treated as a genuinely democratic choice. When the decision is properly going to be some kind of popular vote. Though again democracy is never perfect, and the debate will invariably be a mix of the objective and subjective.

Anywhere else it’s only dialogue that evolves minds. Even the Socratic questioning kind can only go so far in good faith if it expects to involve undermining the other party or reducing a case to absurdity. Any actual mind changing will depend on defensive responses at the time and reflective activity after the event. It is possible to protest too much. It might indicate loss of good faith and skin in different games.

It is the reflection – the internal experience – that might evolve your mind.

=====

[Post Note: Ha, this very morning from Jon Haidt, tweeted by @PoeBrianL:

Illustrates the other point I often make, that the “reasoning” aspect of the mind-changing – or even simple decision-making – is almost invariably a post-rationalisation (“post-hoc reasoning” here), reducing the outcome to some logical objective relations and causes, which is rarely what has actually happened psychologically.

And as it says, whilst I say it is the private reflection that actually changes the mind, it is a rare event compared to all of the other explicit stages of dialogue.

And of course, having thoroughly read and enjoyed The Righteous Mind some years ago, I’ve clearly absorbed Haidt’s thinking into my own. Nothing is invented by one person in isolation. Knowledge and understanding co-evolve.]

[Post Note: Interesting seeming counter-example from James Willis on how we are all however susceptible to persuasion. In the context of this post, I point out that this is persuasion to act. Nothing in this story changed anything about what James “believed”.]

[Post Note:

Interesting and  believable from a many who knows statistical probabilities.]

Pigliucci vs Kastrup on Panpsychism

I have a lot of time for Massimo (Pigliucci) and have found Bernardo (Kastrup) at least interesting and provocative recently in his speculative output. A fascinating “flame-war” broken out on Twitter since Massimo published a “scathing” criticism of a recent Bernardo paper. A paper with an amazingly click-baity “question” for a headline it has to be said.

Sadly, the latter is playing his objection to the criticism to the gallery, including Deepak Chopra, so hard to sort out content from the flak. Anyway the topic is (or isn’t) pan-psychism, so with my interest in pan-proto-psychism – the same fundamental information underlying both mind-stuff and physical stuff – I thought I’d capture paper, critique & rebuttal for later archaeology.

Paper: The Universe is Consciousness.
(And the SciAm article with the click-baity question headline.)

Critique: Does the Universe Suffer from Multiple Personality Disorder?

Rebuttal: The Remarkable Criticism of Massimo Pigliucci.

Denying that his thesis is panpsychism gets off to a bad start in the executive summary of Bernardo’s original paper:

“there is only cosmic consciousness”

That looks the epitome of pan-psychism to me, even if not “bottom-up” whatever that means (presumably pan-proto-consciousness?)

And, I’m guessing from Massimo’s choice of headline we’re dealing with some analogy too far in multiple universe’s as multiple “conscious personalities”. Certainly “multiple personality disorder” doesn’t appear in Bernardo’s summary but is introduced by the SciAm headline writer.

Oh well, time to read.

=====

[Post Note: The dialogue continues:]

=====

[Post Note: And more “attack and defence”:
Susan Schneider disses panpsychism (after Chalmers) in SciAm.
And Bernardo needs to defend it. Beginning to see this whole thing as just another broad vs narrow definitional argument – the same perennial philosophy runs through all sides. People who overclaim universal consciousness are “woo” and those who are “meh, that’s just how it is” are ignored – meantime professional critics stoke differences over “mysteries” and “unproven” arguments as click-bait. Yawn.]

Sweet Reason

Rarely was a program so well named. Exemplary dialogue handled by Evan Davis on BBC R4 Sweet Reason on “Offense”.

The thesis being discussed was implicitly:
Weaponised Offense Taking
as part of
Identity by Victimhood.

Contentious topic on PC-Ness of free expression. With Jordan Peterson (white-male) and Dr Clare Chambers and Shaista Aziz (non-male / non-white) what a recipe.

And yes, couple of points where mutual buttons were pressed. The philosopher valiantly wanting to keep an objective handle on the “but who / in what position of power” aspect of the context for potentially offensive expression. The “White men …” response from Aziz … classic stuff …

Particularly liked the Rod Liddell example – the “I think we can call 40,000 Romanian immigrants a swarm” one-liner – demonstrating that the context (including the social role of the person) matters. In satirical journalism, the Court Jester role is recognised.

And yet … near perfect summary from Davis … JBP (the white man, naturally!) felt the need to insert his dangers of weaponisation point into the summary … but no actual dissent. And, as Davis noted at a couple of points, mostly violent agreement.

Exemplary on several levels.

Explicit – The topic and the content of the discourse leading to progressive agreement.

Context – JBP is probably red rag to many otherwise intelligent bulls in the current climate, so exemplary in not shrinking from any degree of difficulty.

Meta – The handling of proper dialogue. Balance of differing inputs, but with enforced listening, summarising between the parties, ad-hominems and adversarials suppressed.

Well done Evan Davis. Well done BBCR4 – with more of this there would be no need for any intellectual dark web.

‘Cept maybe marketing and book sales 😉

[Post Note: Also heard the @StephenSackur BBC World / News TV “HardTalk” interview with JBP (h/t @JacobKishere). Sackur clear pushes the critical side on each of 5 or 6 agenda – source as much from critics as his own reading – points, but gives JBP opportunity for clear responses. Good responses, good source of JBP thought in fact? Sackur doing journalist job with no lingering / hidden agenda apparent? Contrast with the (UK) original @CathyNewman i/v where despite the “you got me” ray of light, Cathy still harboured her leftist / feminist agenda, maintained it in the following weeks’ debate in fact.]
