Falling bodies
That moment when you realize, in midflight, that you boarded the wrong plane
For the first time since my conversion to the Catholic faith I don’t think if I was an Anglican now I would have bothered converting. Don’t get me wrong I’d never go back to Anglicanism.. but I don’t think that if I was an Anglican now I’d see the point of being a Catholic. 1/2— Fr David Palmer (@FrDavidPalmer) October 26, 2019

The Incarnation and the image of God
Inerrancy for me but not for thee
Many Christian conservatives profess to defend the inerrancy of Scripture when, in fact, they are defending the inerrancy of their interpretation of Scripture.— Tentative Apologist (@RandalRauser) October 26, 2019
Ehrman v. Williams rematch
In order get the story wrong you'd have to have a different mechanism of information–so it's like they've gone to the effort of doing research to get all the context right and then you're going to say they were casual about the stories; and for that you need to have some sort of system of selective corruption of information that corrupts the most important stuff and leaves all the trivial stuff in place.
What would it take, if you're already committed to the idea that there can't be any mistakes, then how would you be open to the idea that there might be a mistake. It's doing theology, it's not doing history. History isn't done by coming at it with a theological presupposition about what had to happen. You look at the evidence. You don't approach it by saying this has to be right. If you're going to do proper history you can't allow your presuppositions about God to affect the outcome. You're saying Christian history isn't the same as history. If you go to a history department there are criteria.
The joy of solving Rubik's cubes
Some loosely and tenuously connected musings, nothing more:
- Let's divide scientific investigation into two categories: the experimental sciences and the historical sciences.
Generally speaking:
The experimental sciences involve experiments which can be setup under predetermined conditions and repeated. This in turn can be done by teams of different scientists at different places and different times. The cumulative repetition, if the experiment is successful in proving a hypothesis or theory, fosters greater confidence in its accuracy.
By contrast, the historical sciences involve a singularity. A one-time event which cannot be repeated. Consider the big bang in cosmology or the origin of life and evolution in the biological sciences. We can't playback the big bang or how life originated and evolved. Closer to home, I have in mind historical and archeological research, SETI, and forensic medicine.
This doesn't necessarily mean one can't be as confident in theories investigating singular historical events as one can be in theories based on experiments. For example, inference to the best explanation arguments can be quite reasonable.
- Atheists often demand evidence for God in answered prayers and miracles. They want God to demonstrate to them that he exists.
Perhaps some atheists would be willing to see some "extraordinary" miracle like God writing something like "the Bible is true" with the stars. Although I recall a prominent atheist (it might've been Peter Atkins) who said that even if God performed an extraordinary miracle, he would chalk it up to a neurological dysfunction and disbelieve what he saw.
In my experience, though, most atheists demand repeat experiments to test whether an answered prayer or a miracle is truly from God.
However, why should prayers or miracles be subject to repeat experiments? We'd be treating God like a mechanical miracle dispenser. That's not how personal agents work. If I want to test someone and see if they will give me something, I don't ask them to sit in a controled environment, under the watchful eye of people hired to record his every action, and repeat my question to him over and over again to see if there'll be a different result.
Instead, I think prayers or miracles might be better investigated using the tools of investigation in the historical sciences rather than the experimental sciences. Such as inference to the best explanation. Consider the people, circumstances, related events, etc., in and around a purported answered prayer or miracle, on a case by case basis, rule out other possibilities, and so on.
- On a completely different note:
Most people enjoy reading, listening to, and/or watching stories.
At the same time, we enjoy re-reading a good story or re-watching a good movie, even though we know the entire story including ending. We love to re-experience our favorite stories over and over again. For example, many people love to re-watch their favorite movies or television episodes.
However, this isn't true for every story. There are some good stories which we wouldn't want to re-read or re-watch even if we could. Perhaps the stories are good but they're too personally difficult or even traumatic to read or watch again.
Also, there are often stories which we find delightful that we couldn't watch again. Take murder mystery or detective stories. We might enjoy Sherlock Holmes or Agatha Christie, but once the case has been solved, we're not all that interested in going through it again.
I presume that's at least partly because it wasn't so much the story itself that was captivating but finding out what the ending was. Discovering whodunnit. The joy was primarily in untangling the thorny knot of the mystery.
Similar things could be said for other things besides literature. Take the sciences or math. Some scientific or mathematical problems are fun to do on one's own even though everyone knows the answer or how they'll turn out. Other scientific or mathematical problems are more like solving a Rubik's cube or finishing a crossword puzzle.
Just as there different types of scientific investigations, such as investigations focused on repeating and reproducing the same experiment as well as investigations focused on solving a mystery or a puzzle, it's interesting there are stories we enjoy re-experiencing time and time again as well as stories we enjoy but could only read or watch once.
Spontaneous creation
Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going. (Stephen Hawking and Leonard Mlodinow in The Grand Design)
Several problems:
- How do scientific laws "create" material objects? Such as subatomic and atomic particles. Not to mention spacetime itself. These are what the universe consists of, after all.
I can see how scientific laws describe and explain patterns in nature. I can see how scientific laws make accurate predictions about the course of certain natural phenomena. But how do scientific laws have the ability or power to create or cause material objects to come into existence? How does a scientific law like "F=ma" have the ability to make a car materialize out of thin air? How does the law of gravity have the ability to make the universe come into existence? To kick off the big bang?
- Minimally laws describe natural phenomena. As such, what is the law of gravity without the existence of gravity? If the law of gravity exists, then presumably gravity exists too. If gravity exists, then it seems Hawking is arguing gravity is what's created the universe. If so, that would still leave unexplained what created gravity. As well as how gravity could exist before the universe exists.
- However, if it's possible for the law of gravity to exist without the existence of gravity, then where does the law of gravity exist if the universe doesn't exist? Is the law of gravity a free-floating Platonic ideal? Would the law of gravity need to inhere in some mind?
- What does Hawking mean by "nothing"? Does he mean what most people mean when they say "nothing" (a)? Or does he mean what physicists like Lawrence Krauss mean when they say "nothing", i.e., some primordial soup consisting of quantum fluctuations (b)?
a. If the former, then Hawking would be arguing something (the universe) came from literal nothing. How can something come from literally nothing on Hawking's beliefs? (Despite the fact that the law of gravity isn't "nothing". Rather it's "something".)
b. If the latter, then quantum fluctuations are clearly not "nothing" in the normal sense of "nothing". Rather quantum fluctuations are "something". If something (quantum fluctuations) created something else (the universe), then that only pushes the question back a step: where do these quantum fluctuations come from?
- Hawking notes the universe created itself. Spontaneous creation. That's illogical. A flat-out self-contradiction. If something doesn't exist yet, then how can it create itself?
Suppose I have a dog. A friend asks where I got my dog. I reply, my dog created itself, before it ever existed. It just popped itself into existence! How so? By its own sheer willpower? Even though the dog didn't exist to have a will in the first place. All this makes no sense.
This is true for any created object. Such as the universe which Hawking admits is a created object. Otherwise Hawking might have followed early 20th century physicists who argue the universe is eternal. It has always existed. It simply is.
- If the universe "spontaneously" created itself from the law of gravity, then doesn't that suggest the law of gravity isn't so much a "law" as it is something less than a law? I mean, wouldn't that be like saying 1 + 1 = 2, but sometimes spontaneous things happen, and 1 + 1 = 3.14 or 6.022 x 1023?
How would Hawking square this "spontaneous creation" (which suggests chance or randomness) with his uniformitarianism regarding scientific laws as well as the fact that he believes the universe is a closed system?
Keep in mind Hawking subscribes to M-theory rather than (say) quantum gravity.
- Hawking notes it's "not necessary to invoke God to light the blue touch paper and set the universe going". However why assume God is in conflict with a scientific law like gravity?
Suppose a scientific law did have creative powers - or at least have causal powers. Suppose the same scientific law caused the universe to exist. Suppose God exists too. As such, God could have used the scientific law to cause or create the universe. God and a scientific law with causal or creative powers aren't necessarily mutually exclusive.
Indeed, if God exists, the God of the Bible, then God would been the one in whom the laws of nature originate in the first place.
The species problem
THE THREE SPECIES PROBLEMS
The species problem is actually a number of problems that biologists have dealt with since the term was first applied to biological organisms by Aristotle. I call the three main problems the grouping problem, the ranking problem, and the commensurability problem. It will benefit us to clearly distinguish these at the beginning of our discussion and to bear them in mind as we consider the philosophy of species.

"In Christ"
Microevolution and macroevolution
What's the distinction between microevolution and macroevolution?
Traditionally the distinction is supposed to be at the species level. Micrevolution involves evolutionary changes within a species, while macroevolution involves evolutionary changes beyond a species. Such as when one species becomes another species. Or one species becomes two species (speciation).
- Yet, today, many scientists disagree with how to define a species. What, precisely, makes a species a species?
- Also, why is the focal point of macroevolution at the species level? Why is species where we draw the line between microevolution and macroevolution? After all, isn't evolution supposed to be akin to climbing Mt. Improbable? If so, then evolution is simply a gradual but continuous series of changes in one direction (give or take). Hence, why couldn't the line be drawn elsewhere?
- In fact, is it even a line so much as an outline or sketch? A fuzzy boundary?
- Moreover, aren't there multiple blurred lines?
- As such, the traditional demarcations between microevolution and macroevolution seem to overemphasize the significance and roles of species and speciation.
- Yet, if the borders are hazy enough between microevolution and macroevolution, then that could potentially affect the theory of evolution as a whole. After all, of what use are concepts like microevolution and macroevolution if the borders are so hazy? We might as well simply call microevolution "small change" and macroevolution "big change" for all the explanatory power these terms have.
- Macroevolution is supposed to be reducible to microevolution. Macroevolution is supposed to be the accumulation of small genetic changes over time (microevolution). Macroevolution is a continuous spectrum of microevolutionary changes.
All this requires genetic changes. How do genetic changes occur? There are several ways, but the primary driver of these small genetic changes is supposed to be random mutations. In addition, these genetic changes can't be deleterious mutations, or even neutral mutations, but they must be beneficial mutations, in order to drive phenomena like speciation. However, the vast majority of mutations are not beneficial mutations. And according to mathematicians, the problem isn't solved even if given hundreds of millions of years to work with.
Biological information
In this post I'm going to talk about biological information, which in turn is relevant in debates over evolution.
However this post is just an introduction. As such I'm going to simplify a lot of things. I realize I'm sacrificing technical accuracy but I'm doing so in order to get some main ideas across for those who might have zero background in all this but who wish to be able to make a foray into the debate over evolution.
Without further ado:
What lies at the heart of every living thing is not a fire, warm breath, not a 'spark of life'. It is information, words, instructions. If you want a metaphor, don't think of fires and sparks and breath. Think, instead, of a billion discrete digital characters carved in tablets of crystal. If you want to understand life, don't think about vibrant, throbbing gels and oozes, think about information technology.(Richard Dawkins, "The power and the archives", The Blind Watchmaker)
- Let's start with a book, computer code, and DNA:
A book contains pages and text, but the pages are just paper and the text is just ink. Rather it's the words that convey the story. Not the words as text, but the words as information.
A computer program contains code, but code is fundamentally just a pattern of binary digits: 0s and 1s. Rather it's code as a set of instructions for a computer to execute that makes a program functional. Hence code isn't merely bits but code is information.
The DNA molecule contains four bases (adenine, cytosine, thymine, guanine), but these bases are ultimately atoms (e.g. carbon, hydrogen, oxygen, nitrogen), and atoms are just physical particles. Rather DNA (as genes) is biological information which can be transcribed and translated to build an organism.
- These aren't mere arguments from analogy (pace Dawkins). I'm not saying text is like code which is like DNA. Rather this is a comparison of information. I'm suggesting the common denominator in all three is information.
- Yet information is invisible. We can't sense it, not directly, but it exists. How does that work on atheism/naturalism and evolution/neo-Darwinism?
- An atheist like Dawkins might argue information emerges from physical properties. Such as in the arrangement of words, code, or DNA.
However, even if so, what would cause the information to be arranged in a particular manner? How does inert matter arrange itself? What causes the letters of the English alphabet to form words if left on their own? What causes DNA to arrange itself in a particular genetic sequence if it is merely a non-living molecule? Let alone a molecule which self-organizes and self-perpetuates.
- Is it natural selection? Since when did natural selection act at the atomic level? How does natural selection act on subatomic particles?
- Moreover, even if a few letters could, somehow, by chance, arrange themselves into words, and words into sentences, and sentences into paragraphs, and paragraphs into chapters, and chapters into a book, each subsequent step would seem to prove increasingly challenging. It's the old question of how long it takes for a monkey to type out the works of Shakespeare.
- There may need to be new information at each subsequent step. A phrase like "In the beginning" may have arranged itself randomly, not to mention somehow well enough to convey meaning, but the sentence "In the beginning God created the heavens and the earth" contains more information. Namely "God created the heavens and the earth".
Likewise it's one thing to have a single gene, but it's a lot more to have an entire genome. Let alone an entire organism.
Hence a question which needs to be addressed is from where does this extra information come? Who or what is adding extra words or sentences or paragraphs into our book? Who or what is injecting additional information into each subsequent step?
Otherwise is the information self-generated somehow, like an artificially intelligent computer writing new code for itself? How so? That seems highly implausible in the earliest lifeforms which surely would have not been anything like an A.I. computer.
- Any time information is generated, there needs to be some way to check it for errors. Quality assurance. Yet could one physical entity (an error checking mechanism) have (more or less) co-evolved with another physical entity (e.g. a molecule like RNA or DNA)? How could a complex error-check have evolved roughly simultaneously with a presumably simple molecule in the origin of life?

Knocking In The Enfield Case
Since the layout of the Hodgsons' house is significant in some of the contexts I'll be addressing below, click here to see a floor plan. I'll be citing Maurice Grosse and Guy Playfair's tapes a lot in the discussion that follows. I'll use "MG" to designate a tape from Grosse's collection and "GP" to designate one from Playfair's, so that MG2B refers to tape 2B in Grosse's collection, GP60A refers to 60A in Playfair's, and so on.
If you click here, you can listen to some of the knocking and watch a few witnesses discussing its characteristics. However, the large majority of the knocking on the tapes doesn't sound as unusual as what's played in the clip I just linked, and the knocking didn't always move around the way Grosse describes. It did sometimes have those characteristics, though, as well as other traits I'll be discussing below. I suspect the qualities of the knocking varied for reasons similar to why an individual's speech patterns, diet, dress, and other characteristics vary in everyday life. The poltergeist could have behaved differently on different occasions depending on how much energy it had at the time, its mood, what it was trying to accomplish, and so forth.
