What is Death

In reading through a number of the threads, I’ve been struck by apparent conceptual acceptance most folk have with the term “death”, taking for granted (it appears) that everyone else reading the term understands it pretty much exactly as the poster intended. However, it also appears to me that there are a few different underlying understandings of the meaning of that term.

I for one am not and never have been all that comfortable conceptually with the term. I find the term to be sort of a contrast place holder for “that which is no longer alive”, but vaguely defined. And from there different folk attach all sorts of esoteric or assumed baggage that I don’t fully grasp or understand. For example, some folk apparently think of “death” as a thing – an actual object independent of (though clearly tied to) living things. I don’t understand that concept. Then there are some folk who think of “death” as something like a transition or perhaps threshold (portal…door…take your metaphorical pick) that living things “pass through” when they “lose life”. Uhh…oookay… And then there are some folk who think of death as something like a state of existence – like sleep I guess only…uhh…deeper…maybe? I do not understand any of those concepts of death.

To me, “living” is a term I use to denote a functioning autonomous system that seeks out resources for the perpetuation of the system’s operation and/or reproduction, and that expels byproducts derived from the system function and resource use. As such, fire to me is very much a living thing. And while in a metaphorical sense I might say that a fire has “died” after it’s gone out, I simply mean that the conditions for that combustion system no longer exist. Similarly, to me, bodies no longer living have simply reached a state where the conditions for the physiological system no longer exist. Systems, by their very nature of resource use and environmental stress, wear. As such, they eventually get to a point they stop functioning. Seems odd to call that “death” to me.

 

Evo-Info sidebar: Conservation of performance in search

Introduction to Evolutionary Informatics, by Robert J. Marks II, the “Charles Darwin of Intelligent Design”; William A. Dembski, the “Isaac Newton of Information Theory”; and Winston Ewert, the “Charles Ingram of Active Information.” World Scientific, 332 pages.
Classification: Engineering mathematics. Engineering analysis. (TA347)
Subjects: Evolutionary computation. Information technology–Mathematics.

Denyse O’Leary, an advocacy journalist employed by one of the principals of the Center for Evolutionary Informatics, reports that I have essentially retracted the first of my papers on the “no free lunch” theorems for search (1996). What I actually have done in my online copy of the paper, marked “emended and amplified,” is to correct an expository error that Dembski and Marks elevated to “English’s Principle of Conservation of Information” in the first of their publications, “Conservation of Information in Search: Measuring the Cost of Success.” Marks, Dembski, and Ewert have responded, in their new book, by deleting me from the history of “no free lunch.” And the consequence is rather amusing. For now, when explaining conservation of information in terms of no free lunch, they refer over and over to performance.1 It doesn’t take a computer scientist, or even a rocket scientist, to see that they are describing conservation of performance, and calling it conservation of information.

The mathematical results of my paper are correct, though poorly argued. In fact, the theorem I provide is more general than the main theorem of Wolpert and Macready, which was published the following year.2 If you’re going to refer to one of the two theorems as the No Free Lunch Theorem, then it really should be mine. Where I go awry is in the exposition of my results. I mistake a lemma as indicating that conservation of performance in search is due ultimately to conservation of information in search.

In Defense of Republican Atheism

In a recent comment, Vincent writes that

However, I would argue that if we believe in human freedom, then that freedom has to include the freedom to bind oneself to a particular vision of humans’ ultimate good – whether it be one that includes God as its core or one which excludes God as a hindrance to unfettered liberty.

I’m very interested in theories of freedom and this idea of atheism as somehow involving “unfettered liberty.”

God loves you. Enjoy your eternity in hell.

A question for Christians, particularly those of the inerrantist stripe.

28 Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell.

Matthew 10:28, NIV

And:

8 He will punish those who do not know God and do not obey the gospel of our Lord Jesus. 9 They will be punished with everlasting destruction and shut out from the presence of the Lord and from the glory of his might 10 on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed.

2 Thessalonians 1:8-10, NIV

“Punished with everlasting destruction.” Is that what a perfectly merciful, perfectly benevolent Father would do to his children?

How did Intelligent Designer/God do it? How was life created?

Since scientists have not been able to prove or even logically explain the origins of life (abiogenesis) by natural, unguided, gradual processes often referred to as the bottom-up approach, it is conceivable to imply that the process of life origins on Earth could be scientifically explained by the design and creation process often referred to as the top-down approach.The top-down approach is sometimes used by scientists in attempts of recreation of small life forms, like a eukaryotic cell.

I will however apply the top-down approach to the process of the designing and creating of human life Intelligent Designer or God (ID/God) could have used.

In other words, the top-down approach is the only conceivable way of the designing and creating life as even in case of the simplest of cells all organelles and functional structures of a cell have to be present, and at the same time, as they are mutually interdependent, including the cell membrane, for it to function or be alive or stay alive. Without the cell membrane or one of the structures or organelles, the cell stops functioning and eventually dies.

The embarrassing “science” of the origins of life: The missing piece of evidence that persuaded scientists to believe in abiogenesis

What comes to your mind when you hear or read the word science? To most the word science correlates with fact, proof or  even truth.

In my countless debates over the years with scientist and supporters of the origins of life (OOL) or evolution, I’ve often asked the question what convinced them so strongly about something, like abiogenesis. The answers I often got would be:

“…I believe it,  because I believe in science…”

Is it really science? 

No doubt to many, whether scientists or not, the word science is often paralleled with trustworthiness, credibility, reliability, soundness and even authority and influence.

”If something is dubbed as “science”, you’d better believe!” – many would say.

My thoughts on JohnnyB’s new view of Irreducible Complexity

Jonathan Bartlett, known here as JohnnyB, has written a very thought-provoking post titled, A New View of Irreducible Complexity. I was going to respond in a comment on his post, but I soon realized that I would be able to express my thoughts much more clearly if I composed a post of my own, discussing the points which he raises.

Before I continue, I would like to say that while I find JohnnyB’s argument problematic on several counts, I greatly appreciate the intellectual effort that went into the making of his slide presentation. I would also like to commend JohnnyB on his mathematical rigor, which has helped illuminate the key issues.

Without further ado, I’d like to focus on some of the key slides in JohnnyB’s talk (shown in blue), and offer my comments on each of them. By the time I’m done, readers will be able to form their own assessment of the merits of JohnnyB’s argument.

Confabulation

An interesting essay in Aeon by neurologist Jules Montague:

Why is the brain prone to florid forms of confabulation?

She had visited Madonna’s mansion the week before, Maggie told me during my ward round. Helped her choose outfits for the tour. The only problem was that Maggie was a seamstress in Dublin. She had never met Madonna; she had never provided her with sartorial advice on cone brassieres. Instead, an MRI scan conducted a few days earlier – when Maggie arrived at the ER febrile and agitated – revealed encephalitis, a swelling of the brain.

Now she was confabulating, conveying false memories induced by injury to her brain. Not once did Maggie doubt that she was a seamstress to the stars, no matter how incongruous those stories seemed. And that’s the essence of confabulation: the critical faculty of doubt is compromised. These honest lies were Maggie’s truth…

‘Memetics is a Dumb Explanation’ says Dennettian ‘naturalist’

The resident professional ‘philosopher’ of TSZ recently wrote this:

“’memes!’ is a dumb explanation.”

Yes, I agree! (Although that person doesn’t seem to know the difference between ‘memes’ and ‘memetics.’ – e.g. I don’t mind ‘memes’ used for popular shared internet links, but that’s not ‘memetics.’)

Well, given the weekend’s significance for a billion+, let’s ‘crucify’ memetics then. Why is ‘memetics’ a dumb explanation? And there’s no need to hold back with merely ‘dumb’. If one is an ideological ‘naturalist’, isn’t one forced into something like ‘memetics’ because they share the same materialist, naturalist, agnostic/atheist worldview as (chuckling at his own supposed lack of self-identity!) Daniel Dennett? Isn’t the built-in materialism of ‘memetics’ what made it so attractive to certain people and for the same reason obviously not attractive or believable to most others?

RNA editing in cephalopods

From Wired:

But when Stanford University geneticist Jin Billy Li heard about Joshua Rosenthal’s work on RNA editing in squid, his jaw dropped. That’s because the work, published today in the journal Cell, revealed that many cephalopods present a monumental exception to how living things use the information in DNA to make proteins. In nearly every other animal, RNA—the middleman in that process—faithfully transmits the message in the genes. But octopuses, squid, and cuttlefish (but not their dumber relatives, the nautiluses) edit their RNA, changing the message that gets read out to make proteins.

In exchange for this remarkable adaptation, it appears these squishy, mysterious, and possibly conscious creatures might have given up the ability to evolve relatively quickly. Or, as the researchers put it, “positive selection of editing events slows down genome evolution.” More simply, these cephalopods don’t evolve quite like other animals. And that could one day lead to useful tools for humans.

From the paper itself:

Evidence for the Resurrection: Why reasonable people might differ, and why believers aren’t crazy

Easter is approaching, but skeptic John Loftus doesn’t believe in the Resurrection of Jesus. What’s more, he thinks you’re delusional if you do. I happen to believe in the Resurrection, but I freely admit that I might be mistaken. I think Loftus is wrong, and his case against the Resurrection is statistically flawed; however, I don’t think he’s delusional. In today’s post, I’d like to summarize the key issues at stake here, before going on to explain why I think reasonable people might disagree on the weight of the evidence for the Resurrection.

The following quotes convey the tenor of Loftus’ views on the evidence for the Resurrection:

Dennett in The New Yorker

I wanted to bring to your attention a lovely profile piece on Dan Dennett, “Daniel Dennett’s Science of the Soul“.  It’s nice to see a philosopher as respected and well-known as Dennett come alive as a human being.

I’d also like to remind those of you interested in this sort of thing that Dennett has a new book out, From Bacteria to Bach And Back: The Evolution of Minds. The central project is to do what creationists are always saying can’t be done: use the explanatory resources of evolutionary theory to understand why we have the kinds of minds that we do. There are decent reviews here and here, as well as one by Thomas Nagel in New York Review of Books that I regard as deliberately misleading (“Is Consciousness an Illusion?“).

[Note: The profile and/or the Nagel review may be behind paywalls.]

 

Is it easy to get a new protein? A reply to Ann Gauger

In a podcast on the show, ID the Future (March 14, 2017), Dr. Ann Gauger criticized a popular argument that purports to show how easy it is to get new proteins: namely, the evolution, over a relatively short 40-year period, of nylonase. (Nylonase is an enzyme that utilizes waste chemicals derived from the manufacture of nylon, a man-made substance that was not invented until 1935.) While Dr. Gauger made some factual observations that were mostly correct, her interpretation of these observations fails to support the claim made by Intelligent Design proponents, that the odds of getting a new functional protein fold are astronomically low, and that it’s actually very, very hard for new proteins to evolve. Let’s call this claim the “Hard-to-Get-a-Protein” hypothesis (HGP for short).

To help readers see what’s wrong with Dr. Gauger’s argument, I would like to begin by pointing out that for HGP to be true, two underlying claims also need to be correct:

1. Functional sequences are RARE.
2. New functions are ISOLATED in sequence space.

In her podcast, Dr. Gauger cites the work of Dr. Douglas Axe to support claim #1, when she declares that the odds of getting a new functional protein fold are on the order of 1 in 10^77 (an assertion debunked here). Dr. Gauger says little about claim #2; nevertheless, it is vital to her argument. For even if functional sequences are rare, they may be clustered together – in which case, getting from one functional protein to the next won’t be so hard, after all.

If claims #1 and #2 are both correct, then getting new functions should not be possible by step-wise changes. Remarkably, however, this is precisely what Dr. Gauger concedes, in her podcast, as we’ll see below.

Contradictions in the Christian Bible

Contradictions are rife in the Christian bible. Here at The Skeptical Zone we have recently discussed those surrounding how Saul died. We’ve also noted the two conflicting accounts of Judas’ death and what he did with the thirty pieces of silver. There are dozens more.

The Skeptics’ Annotated Bible and The Thinking Atheist are two of several excellent resources on biblical contradictions and absurdities. The sheer volume of contradictions, though, is best demonstrated visually as is done at BibViz:

The creators of this site started with a cross-index of topics in the bible and pulled out those that contradict each other. You can click on the links to get more detail. As a bonus, the site includes references to the sections in the bible that contain Scientific Absurdities & Historical Inaccuracies, Cruelty & Violence, Misogyny, Violence & Discrimination Against Women, and Discrimination Against Homosexuals.

Obviously most Christians aren’t foolish enough to claim their bible is inerrant. Those that do, in the words of Desi Arnaz, have “got some ‘splainin’ to do.”

Why we probably don’t live in a computer simulation

Over at her blog, BackReAction, physicist Sabine Hossenfelder has written a cogently argued article titled, No, we probably don’t live in a computer simulation (March 15, 2017). I’ll quote the most relevant excerpts:

According to Nick Bostrom of the Future of Humanity Institute, it is likely that we live in a computer simulation

Among physicists, the simulation hypothesis is not popular and that’s for a good reason – we know that it is difficult to find consistent explanations for our observations…

If you try to build the universe from classical bits, you won’t get quantum effects, so forget about this – it doesn’t work. This might be somebody’s universe, maybe, but not ours. You either have to overthrow quantum mechanics (good luck), or you have to use qubits. [Note added for clarity: You might be able to get quantum mechanics from a classical, nonlocal approach, but nobody knows how to get quantum field theory from that.]

Even from qubits, however, nobody’s been able to recover the presently accepted fundamental theories – general relativity and the standard model of particle physics…

Indeed, there are good reasons to believe it’s not possible. The idea that our universe is discretized clashes with observations because it runs into conflict with special relativity. The effects of violating the symmetries of special relativity aren’t necessarily small and have been looked for – and nothing’s been found.

Are atheists really atheists as they claim?

I’m pretty sure that most knowledgeable people know that someone who claims to be an atheist is just making an overstatement about his/her own beliefs. As most knowledgeable people who claim to be atheist probably know that even the most recognizable  faces  of atheistic propaganda, such as Richard Dawkins, admitted publicly that they are less than 100% certain that God/gods don’t exist.

My question is: Why would anyone who calls himself an atheist make a statement like that?

Do we have a duty not to procreate?

Writing in the Sydney Morning Herald recently, Australian journalist Ruby Hamad explained her decision not to have any children. Ecological considerations proved to be a “very compelling factor” influencing her decision, leading her to conclude that for her and her partner, having a child would be “the more selfish decision.” Ms. Hamad details her reasons in a passage that makes for disturbing reading:

Our planet is in trouble. We all know this. The Amazon is depleting so rapidly, we have already lost 20 per cent of it and will lose another 20 in the next two decades – just as children born today are coming of age. Lucky them!

The Great Barrier Reef is as good as dead, as everyone who is not Pauline Hanson will admit, but deforestation is also happening in the oceans, thanks to the rise in global temperatures. Meanwhile, the oceans will be commercially extinct by the middle of the century, and the entire Arctic is living on borrowed time…

For lay people, the knowledge that one child born today will add 9,441 metric tons of carbon to the atmosphere is enough to turn them off procreation. “You can never take it back,” said one American woman. “That stopped me in my tracks.”

So, is Ruby Hamad right? In today’s post, I’d like to explain why I believe her logic is profoundly mistaken.

How Did The Designer/God do it?

I’m pretty sure that many creationists/ID proponents and skeptics about materialism have heard that question many times often when materialists get  cornered about their beliefs about the origins of life…The usual question posed by materialists is: How Did The Designer/God do it? We can’t recreate life, so tell us how was it created!

Does anyone have a theory about how ID/God/ET did it?

I have my own,  but I’m just curious how much smarter people than me would answer  the skeptics who often add to their skepticism: Did ID/God/ET just “poofed”  life magically into existence?
