You're also not a girl (I assume). There certainly are more differences between bats and humans than there are between boys and girls, but they're still different. The differences are physical as well as social. There certainly is a "girl role" that is "imposed" on girls, but that role is part of their identity. A boy who'd like to live in that role will not have had the same experiences as the girl.I would say the reason I don't know what it is like to be a bat is because I am not a bat — Moliere
Same here. I wonder if we experienced it the same way, though. Everyone experiences things based on who and what they are, and on their environment.I know what it is like to be poor because I have been poor.
The laws of logic are not contingent laws like man-made laws or even the laws of physics, which are what they are but could have been different. Logic is an essential part of reality: not everything that is logical is real, but everything that is real is logical. I+I=II because you can see II in I+I (just remove the + sign). It does not "appear" from it, like an effect appears from its cause. — Samuel Lacrampe
I know, and I was relating an objection: it depends on the assumption that nothingness should somehow be expected in the absence of a reason. A state of affairs of "nonexistence" is incoherent.I was alluding to Leibniz's cosmological argument. — frank
But it seems reasonable to believe everything has a cause. Only by considering causes to be reasons can the PSR be justified. I see no justification to believe there are necessarily non-causal reasons.The causality principle states that everything has a cause, which is very different from every thing has a reason.
That is all anyone could hope for, but my position is that the alleged persuasive power is a consequence of people failing to see the inherent problems that I've brought up.the FTA is persuasive, as a number of atheists have admitted -- giving it as a reason for positing a multiverse.
I agree with the approach, but disagree with your claim that there is intelligent direction "to that end." This characterization continues the same flawed reasoning by implicitly assuming there is an end (or goal or objective). That is one of my most important points.The strength of the FTA lies in the fact that when many improbable means coordinate to effect the same end, it is usually the case that they are intelligently directed to that end. This is the kind of reasoning used in court cases. So it's quite rational, even though not airtight.
Which sidesteps the important issue. The "realm of application" is the universe after Planck time. That's problematic for drawing conclusions about a broader scope - and a multiverse, and the possibility of differing "constants" is a broader scope.we do know that whatever the fundamental laws are, they closely approximate the physics we have in its verified realm of application.
Sandstone and snowflakes, to name two. But keep in mind that if we're including God among the possibilities to consider, we have to consider all metaphysically possible worlds - and a multiverse with differing constants is every bit as metaphysically possible as is a God. You can't dismiss multiverse for lack of evidence and then propose a God which also has no evidence.Relativist: There are many sorts things that exist in THIS world that would not exist had the constants been different
For example?
Aquinas distinguishes between essence (necessary and sufficient properties) and accidents (contingent properties). Consider humans: there are no necessary and sufficient properties for being human - every portion of human DNA is accident. You can define a sortal - i.e. a set of properties that divides up all beings into two sets: human and non-human, and if you only did that with the set of people alive today, you'd have no difficulty. However, try to divide up all living things that have ever lived on earth into human and non-human, and you will unavoidably have to draw an arbitrary boundary. Among the ways one identifies a species is that members of that species can breed and produce another of that species. Consider an ordered set of all your ancestors through the evolutionary past: each generation was the same "species" as the prior generation - able to interbreed. And yet, you are not the same species as your Australopithecus ancestors (as well as a great many other ancestors in the evolutionary chain.Aquinas is quite clear that neither essence nor existence are "things." They are just "principles" -- the foundation in reality (objective basis) for saying that a thing is (existence), and what kind of a thing it is (essence). So, if you think that there's an objective basis for saying something exists, you agree with Aquinas that it has "existence," and if you think there's an objective basis for saying you're human and Fido is a dog, then you agree that you and Fido have essences. There is nothing more to essence and existence than that.
The nature of the things that exist (such as whether they consist of form and substance, or whether they are states of affairs) is not a "fundamental fact" that comes from experience - rather, it is a postulated paradigm - an assumption.Relativist: My issue is that if you're going to accept unprovable postulates in your preferred metaphysics you must accept them in alternative metaphysics to avoid a double standard.
We know our fundamental facts directly from experience, not indirectly, via proofs.
The Loop Quantum Gravity cosmological model is dependent on Loop Quantum Gravity theory being true, which is testable in principle (see this). The Cosmology also predicts observable remnants in the CMB, but will require more precise measurement.What is the specific falsifiable prediction [in a rigorous mulitiverse hypothesis]?
That's not what I asked. I asked if you believe the laws of nature EXIST (not operate) independently of the entities that exhibit them.I am not saying that they can operate independently of the things they operate on. That would be nonsense.
Consider the fact that there's nothing unnatural about the fact that there exist fictional narratives with fictional characters - so yes, these DO exist in the real world (as fictions). Fictions exist in our minds, just as redness exists in our minds.Humans are part of the physical universe, so this suggests redness (that thing we perceive and contemplate) is part of the physical world. — Relativist
This is like saying that Harry Potter and Sherlock Holmes exist in the real world, because the books and films that represent their adventures exist in the real world. I don't think this argument holds water. — Pattern-chaser
OK, but this is because of the nature of "redness." I'll relate a philosophical thought-experiment.The definition you use for "red" is unusual, and does not include many or most of the shades of meaning used by humans when they say "red"....My view is broader, and tries to embrace all of the meanings that humans conventionally use "red" for. — Pattern-chaser
The evolution of complex structures is not due to decision making. I suggest you read up on natural selection.at what point did a single cell decide it was going to start splitting and growing into a heart?
and if it DID, why?
was it already a brain that knew it needed a heart?
was a Primordial Goo Brain smarter than we are now?
that it (accidentally randomly) knew it needed a complex operating system??
but even if it WAS that smart -- how the heck did it manage to keep the body alive while it was
3D printing itself over a million years? one. piece. at. a. time. when all the pieces function as a WHOLE? — Uniquorn
You've reference the Fine Tuning Argument, and I inferred that you were referring to the FTA for God's existence. If I'm mistaken that your agenda is to "prove" God's existence based on the alleged "fine tuning" of these constants, then there's nothing really to discuss. But if that is what you have in mind, then I see an argument from ignorance behind the reasoning: we don't know why the constants are in this narrow life permitting range, therefore it must be due to design.You've bandied about "arguments from ignorance" for a while I don't recall advancing any -- nor you pointing out any. On the other hand, you're using our ignorance wrt a multiverse as a counter to the FTA. Please be specific as to any arguments from ignorance you think I'm making.
And as I keep repeating, we don't know what the true fundamental laws of nature actually are. All we can know is what we have access to, and that's the way the laws of nature manifest in this universe. To avoid continuing to go in circles, I'll interject that our fundamental disagreement is really metaphysics, not the physics. We can agree that known physics does not entail a multiverse, much less variations in the so-called fundamental constants. This takes our epistemic quest out of the realm of (narrowly defined) physical possibility. What is the implication? It just implies the answer is beyond the realm of current physics. If you were to claim, "therefore it must be God" you would be committing an argument from ignorance. Why should we think a supernatural being is more likely than an unknown natural cause? The converse seems more likely because we don't know that there exists anything other than the natural world.But, as I keep repeating, the MWI is not evidence against the FTA because every "world" has the same physical constants
So what? This universe happened to produce a set of things that we characterize as "living." Why regard this as special?No, the FTA infers that life was intentional from the fact that the variables have the exact values required to produce life.
You are relating a coincidence (two things unexpectedly coinciding). What is life coinciding with?Suppose you ran a store with only one thing costing $1.59 and a young person plunks $1.59 on the counter, looking at you expectantly. It would be a rational inference to conclude that the child wants the one thing costing $1.59.
I considered this implied, but OK, let's formally add it: Consider a metaphysically possible world, W, which contains complex objects of type T which would not exist had the fundamental constants differed from what is actual in that world.Relativist: "Consider any metaphysically possible world W, which contains complex objects of type T. One could argue that W was fine tuned for T.."
This is simply false. For the argument to be persuasive, you need the additional datum at the core of the FTA, viz., that minute variations of W's constants would preclude the existence of Ts.
I believe you're right about Aristotle. I had confused his metaphysics with that of Thomas Aquinas. Thomist metaphyics has the view of essence that I was referring to: it is an integral part of his metaphysics, and yet it is pure assumption that there is such a thing.You are confusing my individual characteristics with what allows me to be called a "human." Aristotle's essences are not individual, but specific. So, "Essence entails the existence of necessary and sufficient properties for individuation" is simply false. "Essence entails the existence of necessary and sufficient properties for delineating 'kinds'" is true.
Sounds similar to Thomist metaphysics, and it again sounds like an assumption - not something that we know exists due to evidence, but rather something that is postulated. My issue is that if you're going to accept unprovable postulates in your preferred metaphysics, you must accept them in alternative metaphysics to avoid a double standard. Every metaphysical theory depends on postulates (sometimes called "first principles").My metaphysical framework is dynamic realism -- that "existence" is convertible with "the power to act in some way," and a being's "essence" is a specification of its possible acts. (This isn't Aristotle's definition of "essence,")
All physics is rooted in empirical data, even when at the stage of hypothesis. Any physics hypothesis may assume physical structures that are not observable- consider quantum field theory. Nevertheless theories are falsifiable, and so are the rigorous multiverse theories, such as Loop Quantum Cosmology which is derived from Loop Quantum Gravity (an incomplete quantum theory of Gravity.Relativist: We weren't discussing evidence. You had alleged the multiverse hypothesis was "mythological" and that it was not falsifiable.
A theory is mythic if it has no evidentiary basis. It is unfalsifiable if no evidence can falsify it. You did not show I was wrong on either count. ("I admit there is no evidence for a multiverse.")
The dependency of life on the universe having these constants within a narrow range is accepted science, but it is still nothing more than a post-hoc analysis. It's somewhat interesting that we wouldn't have existed had these constants differed. The error in reasoning occurs only when attempting "prove" God's existence by this fact. And it most certainly IS consistent with the scientific endeavor to explore whether or not there's a reason for the constants being what they are - and the only valid way to explore this is to consider if and how they could have been DIFFERENT. This has nothing to do with figuring out why there is life, because life just happens to be something that exists in this universe. Some naturalists fall for the bait and try to answer it, but they're as misguided as those who tackle the equally presumptive question: why is there something rather than nothing?You seem confused as to my position. I'm open to the possibility of a multiverse. I even think it's a sensible line of inquiry. What I'm discussing is the current epistic value of the multiverse hypothesis as opposed to the FTA. It should be obvious that any hypothesis lacking supporting evidence (as you agree wrt a multiverse) has no epistic value. On the other hand, the FTA is based on evidence and peer-reviewed calculations. I agree that the FTA is not a "proof," but it does have epistic value. So it makes a far stronger case in the legal sense.
You are mistaken about Armstrong's metaphysics - it's pretty complete, and it's coherent. We don't necessarily need to explore it in detail. And no, I'm not actually committed to Armstrong's metaphysics. I bring it up when other metaphysical assumptions are made to show that any conclusions that are made are contingent upon those metaphysical assumptions being true.I am willing to grant this is the case. Since my sentence is perfectly meaningful in normal English language discourse, I conclude that Armstrong's metaphysics is inadequate to normal English discourse. You are perfectly free to limit yourself to their framework. I prefer to be open to many complementary projections of reality.
Existence is a concept referring to the quality of "existing." To exist is to be in the world (world in the generic sense, not necessarily limited the physical world). The world contains beings (=existents, the things that exist). The set of all beings = the totality of reality.“Existence” is metaphysically-undefined. In any case, no one denies that this physical world is real in its own context, and that your life, and this physical world which is its setting, are real in the context of your life.
"Sleep" seems a poor characterization. Death is the cessation of being, if there is no "afterlife." If there is an afterlife, there is no "sleep" - there's just a transition of states of being. In neither case does the term "timelessness" seem applicable. "Timelessness" suggests to me something that does not experience time. "Sleep suggests subtle change in state of living consciousness, not a cessation of consciousness nor a transition of states of being.The finality of that sleep at the end of lives, and the absence of any knowledge, memory or perception that there is, was, or could be, such things as identity, time or events, suggests the use of the word “timelessness”.
I'll clarify. Math and logic use the symbol, "∃" , which is read, "there exists". This is not an ontological claim, it is used to analyze mathematical and logical relations. I label this a "hypothetical existence." It may, or may not, refer to something that is in the world. But (hypothetically) if it exists, we can deduce various things about it.So all you’re doing is defining your “objective existence” as more than hypothetical existence....
...for Materialists, of course.[/quote]Relativist:" That there exists an external, physical world is a properly basic belief, an epistemological foundation for all else." — Michael
I strongly disagree. Our innate, nonverbal view of the world is our epistemic foundation.Your experience is the epistemic foundation for all else.
You are imaging things. I did no such thing.You’ve admitted that you don’t have an answer regarding in what noncircular way you think that this physical world is more than that.
Relativist: "We are not taught that there is an external world "
.
There’s undeniably an external world in our experience. That’s what our experience story is about.
Not me. I was raised Catholic. I eventually came to question what I was taught, just as you did.We’re taught, from an early age, to be little Materialists and Science-Worshippers. Some of us never question that.
Who said it did?As animals, we instinctively deal with our surrounding physical world as best we can. Kids, and most people, and (for all we know) all other animals leave it at that, and don’t ask what there really is, or why they’re in a life, or why there’s something instead of nothing.
.
…but that doesn’t support Materialism.
We have that in common.if you say that you don’t know what ontology I believe in, that might be because I emphasize that I don’t claim or assert one.
You've made two errors: 1) you assume I'm a materialist; 2) you don't understand the principle of parsimony."I apply the principle of parsimony."
.
It doesn’t support you. Materialism, with its big brute-fact*, fails the Principle of Parsimony.
I agree that we can't confirm our properly basic beliefs. That does not preclude having rationally justified beliefs. My theory is that we have these properly basic beliefs because we are a product, and component, of this world (and this is true irrespective of whether there is a supernatural creator). This could be wrong, of course, but neither you nor anyone else has given me a reason to doubt it.But no, there’s absolutely no evidence, no physics-experiment, to support a claim that this physical world is other than the hypothetical setting in your hypothetical experience-story, a complex abstract logical system.
You repeated this multiple times. You seem to be saying, "nothing you've said has convinced me that my assessment is false." That's great, but I wasn't trying to convince you of anything, I was just sharing what I believe. I hope you realize that such statements don't give me any reason to think I have it wrong either.None of that supports a claim that this physical world is other than what I said it is.
You are casting my assertions in terms of subjectivism, that is certainly not my claim. Of course, you can believe whatever you like. I hope you aren't trying to convince me of anything, because if you are- you're failing miserably.I addressed your Subjectivism argument in my previous post.
That is not "an ontology" it is an ontological claim. OK, I hear you and I disagree with you.To propose an ontology, I’d propose that the physical world is nothing other than part of a logical system of inter-referring abstract facts, and that the describable world consists of nothing other than that.
As I said above, I don't believe in an ontology. I do believe certain things exist (e.g. the physical world), and other things possibly exist (such as gods), and I'm just not sure about the nature of the mind (is it really something immaterial?)You’re the one with an ontology that you aren’t specifying or being clear with us about.
I prefer to use the term "fact" to refer to an element of reality as distinct from propositional descriptions of a elements of reality. Abstractions can be the subject of propositions and discussed as such - if this is what you mean, I completely agree.At least as discussion-topics, there uncontroversially are abstract facts
I think you may misunderstand the principle of parsimony. It seems to me that whatever is the foundation of reality, it entails a very complex brute fact. An omniscient, immutable God who created material reality is an extremely complex brute fact. But the principle of parsimony is actually an epistemological principle that we should refrain from making any more assumptions than necessary to explain the facts at hand. It does NOT mean that reality is simple.“Physicalism” (a regrettable two-meaning word for Materialism (or for a philosophy-of-mind position)) is blatantly unparismonious, with its big, blatant brute fact.
You had several similar reactions wherein I tell you something I believe, and then you react in this way (what, inferring that I think you DON'T believe this?). I'm not suggesting what you do, or don't believe, I'm just telling you what I believe.Relativist:" it seems irrational to believe something just because it is POSSIBLY true"
.
And what do you think that I believe in.
That's an interesting and bizarre perspective, since you've given no reason to believe "the physical world is nothing other than part of a logical system of inter-referring abstract facts." And of course, I disagree - there are very good reasons to believe the physical world is something other than this. I expect we'll just have to agree to disagree on this.I emphasize that, in this discussion, I’m not advocating an ontology or metaphysics. I’m merely pointing out that there’s no reason to believe in an ontology that says that this physical world is other than what I’ve said [the physical world is nothing other than part of a logical system of inter-referring abstract facts])"
This one: "the physical world is nothing other than part of a logical system of inter-referring abstract facts"Relativist:" …, or do you think you can show that your view is more worthy of belief than mine? "
.
What belief of mine are you referring to? If I made a controversial claim, what was it?
Of course I am, but I believe we are also able to contemplate objective reality, that we actually can escape subjectivism. I believe you have things backwards when you claim the physical world is a logical system of inter-referring abstract facts - these abstract "facts" (actually: propositions) are descriptive of what actually IS. Logic is not an existent, it is a rational process, so to claim the physical world is a "logical system" is a category error. Again, we needn't agree - and I doubt we ever will.So you aren’t central to your experience?
I've given you one: we believe it innately, and it is reasonable to think that this is because we are a product of that substantial world. Now you can't make that claim; you have to find a reason to reject what I've said.“I suggest that this life and the physical world in which it is set, are completely insubstantial”
.
Relativist: Why do you believe such a thing?
.
I merely claim that there’s no reason to believe otherwise.
We both are. But at least mine is grounded in our innate view of the world. I don't have any idea how you came up with your bizarre view.let’s be clear which of us is advocating an unverifiable, unfalsifiable proposition.
If the physical world exists, and it is nothing more than "part of a logical system of inter-referring abstract facts," then you must believe abstract facts exist. If abstract facts do not exist, then the physical world doesn't exist.No need to quibble about how or if the abstract facts exist. I haven’t claimed that they exist other than as subjects of discussion or mention.
100 years after the big bang, there was no one around to have an "experience story". At that point in time, did abstract facts exist?Saying that the abstract facts depend on there being someone to discuss them is meaningless, because there are inevitably infinitely-many experience-stories with their complementary protagonists, some of whom discuss abstract facts.
This is an assumption: "the physical world is nothing other than part of a logical system of inter-referring abstract facts."what I’ve been saying doesn’t include any assumptions, brute-facts, beliefs or controversial statements.
Our knowledge about everything is limited, and yet we end up believing things anyway. We typically come to a belief based on the information at hand, and that's why the mere possibility of inscrutable reasons doesn't defeat a belief in God's non-existence that is formed based on the information we actually have.An Omni-benevolent God as judged with our limited knowledge? Yes or no?
Christians choose to love God while their on earth, and yet they continue to sin.The answer is that the only reason that those in heaven do not sin is because they have chosen to love God.
Sure, ...and that's also why some people conclude a 3-omni God doesn't exist. If there is such a God then there are compensating gods, but IF there are no compensating goods, then such a God cannot exist. Contemplate the evil in the world without presumption of God's existence, and seeing no compensating goods, then the conclusion is obvious. (That's not to suggest this need be the end of the epistemic quest)and as above - the theist answer remains, compensating goods or morally justifiable reasons. Which is why this issue always inevitably spirals to this point and has for many many years
My premise makes no assumption like this, but you can suggest this as the environmental condition that results in the absence of sin. But the question becomes: Why would an omnibenevolent God place the creatures that he loves in any OTHER environment? Why did he choose to make us suffer?On P4. Your proposition is assuming there is evil in heaven that the free willed beings in heaven would be free to chose if they desired, but don't because of their nature created by God. I do not think it is a valid assumption that there is evil in heaven. Or at least a case need to be made for it.
Sure: there is one all encompassing state in a quantum system, but the issue is: how does the classical world that we experience emerge from the quantum system that comprises reality. A realist view of MWI is based on the ontological commitment that physical reality is a quantum system, and that the classical world of experience is an eigenstate of that QM system. So the "world branching" is (technically) just a classical perspective: each eigenstate is a classical "world."When I say that Everett's interpretation is more epistemological than ontological, I am speaking about the "manyness" of the worlds envisioned...It is not many worlds on top of each other, but a mathematical means of representing a single state in as a sum of mathematical forms called "eigenfunctions."
It's moot what you see in the literature because you're seeing response based on a flawed premise. The alleged "fine tuning" is a product of post hoc analysis. The FTA has the unstated assumption that life was a design objective. Consider any metaphysically possible world W, which contains complex objects of type T. One could argue that W was fine tuned for T. What is special about life? It's special to us, but that doesn't make it intrinsically special. I feel special to myself, and am the product of a series of improbable accidents of pairs of individuals who happened to reproduce: was I the product of a priori design? If you disagree with my analysis, try reformulating the FTA without assuming life is intrisically special, or assuming the world was "fine tuned" (a question begging concept).So, the physics showing that minute variations in the constants leads to conditions unsuited to life depends on the assumption of design? Would you care to provide an example showing how this assumption changed the calculations? Or even how it could change the calculations? The vast literature generated by naturalists to support the possibility of a multiverse as an explicit alternative to fine-tuning shows that some very prominent physicists and cosmologists take the calculations quite seriously.
Aristotle's reasoning was a product of his time, but with advances in science and analytic philosophy, we can see that the notion of essence has no empirical basis. And yet there continue to be philosophers who embrace the metaphysics (e.g. Edward Feser).Aristotle was an empiricist. He did not "hypothesize that 'essence' exists." He said that our definitions of universal terms reflect common elements in their instances and that we may name those common elements the object's "essence." In other words, essences are the foundation in reality for essential definitions. I do not see how any empiricist could deny that there are real differences, found in individuals, that allow us to say this is human and this a canary. Biologists do that every time they determine what species an organism is.
We weren't discussing evidence. You had alleged the multiverse hypothesis was "mythological" and that it was not falsifiable. I showed that you were mistaken on both counts. I admit there is no evidence for a multiverse, but there are good reasons to think this might be the case - as I discussed. Multiverse is consistent with what we know, and it is entailed by some reasonable extrapolations about what we know (these extrapolations are what I referred to as "incomplete theories"). Science advances in this way; accepted theory does not arrive in its final form.Really? "Incomplete" theories now have evidentiary standing? This merits no further discussion.
Errors in the analysis are self-correcting - that's what peer review is for." So incomplete that it has made no falsifiable prediction and its supporters mix results from logically inconsistent versions. I will not repeat the harsher and less charitable criticisms.
Agreed, but this doesn't make metaphysical speculations that are devoid of math any prettier. I bring these things up not because they are necessarily true, but rather to show why we shouldn't be seduced by metaphysical explanations that implicitly rely on arguments from ignorance. We should be agnostic to the existence of multiverse, not hastily dismissing it for insufficient empirical basis while declaring victory for a deism that also lacks an empirical basis.I merely note that dressing ignorance in mathematical lace doesn't make it a thing of beauty.
That's fine as long as you refrain from arguments from ignorance as I just discussed.I have no problem with physics that only works for empirical reality. I am not sure why anyone would -- accept to rationalize a faith position.
You seem to have some physical/metaphysical framework in mind, and are judging the Armstrong-Tooley framework from that perspective. That is the category error. Armstrong developed a fairly complete metaphysics, and it can account for everything you've discussed - but it of course does so very differently. So, for example, from the perspective of Armstrong's metaphysics, it's meaningless to assert "laws of nature lack the defining characteristics of matter". We don't really need to debate which metaphysics is true, as long as you don't implicitly insist that your metaphysical assumptions form the proper basis for exploring metaphysical truths.You're arguing skew to the point here. It is not a question of whether we think abstractly or not. The question is: what are the properties of the object of thought. We think abstractly of quanta and fields, yet we know they are material because they have mass-energy and parts outside of parts (extension). We think abstractly of works of art, but we know they are composed of atoms. When we think of the laws of nature, our concept does not involve parts outside of parts -- they are not spatially divisible -- or the possession of mass-energy. Thus, laws of nature lack the defining characteristics of matter -- not because our thoughts are abstract, but because what we are thinking about falls into a different category.
This flavor of string theory entails multiple possible "low energy physics" (the physics we observe), and this string theory is falsifiable.The problem arises because string theory is formulated most naturally in 10 or 11
spacetime dimensions, whereas the spacetime of our perceptions is four dimensional. The
extra space dimensions are rendered unobservable by a process called compactification:
they are rolled up to a very small size. ... This basic notion may be extended to any
number of extra dimensions, but then the process of compactification is no longer unique.
In general, there are very many ways of compactifying several extra dimensions. When
additional degrees of freedom in string theory are taken into account, compactification
may involve several hundred variables, all of which may vary from one region of the
universe to another. These variables serve to fix the low-energy physics, by determining
what sorts of particles exist, what their masses might be and the nature and strengths of
the forces that act between them. The theory also permits compactification to spaces with
other than three dimensions. Thus string theory predicts myriad possible low-energy
worlds. Some might be quite like ours, but with slightly heavier electrons or a somewhat
stronger weak force. Others might differ radically, and possess, say, five large (i.e.
uncompactified) space dimensions and two species of photons.
