It seems, despite UD’s resources tab, some still struggle to understand ID in the three distinct senses: inference, theory/research programme, movement. Accordingly, let us headline a clarifying note from the current thread on people who doubt, for the record:

[KF, 269:] >>. . . first we must mark out a matter of inductive reasoning and epistemology. Observed tested, reliable signs such as FSCO/I [= functionally specific, complex organisation and/or associated information, “fun-skee”] beyond 500 – 1,000 bits point to design as cause for cases we have not observed. This is the design INFERENCE.

A classic example of FSCO/I, the organisation of a fishing reel
A von Neumann, kinematic Self Replicator, illustrating how an entity with
self-replication reflects considerable additional FSCO/I, where
the living cell embeds such a vNSR
The metabolic network of a cell exhibits FSCO/I in a process-flow, molecular nanotech self replicating system
Petroleum refinery block diagram illustrating FSCO/I in a process-flow system
The design inference reduced to a flowchart, the per aspect explanatory filter

Note, inference, not movement, not theory.

Following the UD Weak Argument Correctives under the Resources tab, we can identify ID Theory as a [small] research programme that explores whether there are such observable, testable, reliable signs, whether they appear in the world of life and in the cosmos, whether we may responsibly — notice, how duties of reason pop up naturally — use them to infer that cell based life, body plans, the cosmos etc are credibly the result of intelligently directed configuration . . . and that’s a definition of design. This, in a context where the proposed “scientific” alternative, blind chance and/or mechanical necessity has not been observed to actually produce things exhibiting FSCO/I etc.

Logically, this is an application of inductive reasoning, modern sense, abduction.

Which is common in science and is commonly held to ground scientific, weak philosophical sense, knowledge. Weak, it is open ended and can be defeated by further analysis and evidence, warranted, credibly true [and so reliable] belief.

Going beyond, where we have further information, evidence and argument we may explore whodunit, howtweredun, etc.

Such is after all commonplace in technical forensics, medical research, archaeology, engineering [esp. reverse engineering], code cracking etc. I guess, these can be taken as design-oriented sciences. Going back to 4th form I remember doing natural science explorations of springs. Manufactured entities. So are lenses, mirrors, glass blocks, radio systems, lasers etc.

Beyond the theory, there is a movement, comprising supporters and friendly critics as well as practitioners consciously researching design theory or extending thinking on it and applying same to society or civilisation, including history of ideas.

The first major design inference on record in our civilisation is by Plato, in The Laws, Bk X:

Ath [in The Laws, Bk X 2,360 ya]. . . .[The avant garde philosophers and poets, c. 360 BC] say that fire and water, and earth and air [i.e the classical “material” elements of the cosmos — the natural order], all exist by nature and chance, and none of them by art . . . [such that] all that is in the heaven, as well as animals and all plants, and all the seasons come from these elements, not by the action of mind, as they say, or of any God, or from art, but as I was saying, by nature and chance only [ –> that is, evolutionary materialism is ancient and would trace all things to blind chance and mechanical necessity, contrasted to “the action of mind” i.e. intelligently directed configuration] . . . .

[[T]hese people would say that the Gods exist not by nature, but by art, and by the laws of states, which are different in different places, according to the agreement of those who make them . . . .

Then, by Heaven, we have discovered the source of this vain opinion of all those physical investigators . . . . they affirm that which is the first cause of the generation and destruction of all things, to be not first, but last, and that which is last to be first, and hence they have fallen into error about the true nature of the Gods.

Cle. Still I do not understand you.

Ath. Nearly all of them, my friends, seem to be ignorant of the nature and power of the soul [[ = psuche], especially in what relates to her origin: they do not know that she is among the first of things, and before all bodies, and is the chief author of their changes and transpositions. And if this is true, and if the soul is older than the body, must not the things which are of the soul’s kindred be of necessity prior to those which appertain to the body?

Cle. Certainly.

Ath. Then thought and attention and mind and art and law will be prior to that which is hard and soft and heavy and light; and the great and primitive works and actions will be works of art; they will be the first, and after them will come nature and works of nature, which however is a wrong term for men to apply to them; these will follow, and will be under the government of art and mind.

Cle. But why is the word “nature” wrong?

Ath. Because those who use the term mean to say that nature is the first creative power; but if the soul turn out to be the primeval element, and not fire or air, then in the truest sense and beyond other things the soul may be said to exist by nature; and this would be true if you proved that the soul is older than the body, but not otherwise.

[[ . . . .]

Ath. . . . when one thing changes another, and that another, of such will there be any primary changing element? How can a thing which is moved by another ever be the beginning of change? Impossible. But when the self-moved changes other, and that again other, and thus thousands upon tens of thousands of bodies are set in motion, must not the beginning of all this motion be the change of the self-moving principle? . . . . self-motion being the origin of all motions, and the first which arises among things at rest as well as among things in motion, is the eldest and mightiest principle of change, and that which is changed by another and yet moves other is second. [–> notice, the self-moved, initiating, reflexively acting causal agent, which defines freedom as essential to our nature, and this is root of discussion on agents as first causes.]

[[ . . . .]

Ath. If we were to see this power existing in any earthy, watery, or fiery substance, simple or compound-how should we describe it?

Cle. You mean to ask whether we should call such a self-moving power life?

Ath. I do.

Cle. Certainly we should.

Ath. And when we see soul in anything, must we not do the same-must we not admit that this is life?

[[ . . . . ]

Cle. You mean to say that the essence which is defined as the self-moved is the same with that which has the name soul?

Ath. Yes; and if this is true, do we still maintain that there is anything wanting in the proof that the soul is the first origin and moving power of all that is, or has become, or will be, and their contraries, when she has been clearly shown to be the source of change and motion in all things?

Cle. Certainly not; the soul as being the source of motion, has been most satisfactorily shown to be the oldest of all things.

Ath. And is not that motion which is produced in another, by reason of another, but never has any self-moving power at all, being in truth the change of an inanimate body, to be reckoned second, or by any lower number which you may prefer?

Cle. Exactly.

Ath. Then we are right, and speak the most perfect and absolute truth, when we say that the soul is prior to the body, and that the body is second and comes afterwards, and is born to obey the soul, which is the ruler?

[[ . . . . ]

Ath. If, my friend, we say that the whole path and movement of heaven, and of all that is therein, is by nature akin to the movement and revolution and calculation of mind, and proceeds by kindred laws, then, as is plain, we must say that the best soul takes care of the world and guides it along the good path. [[Plato here explicitly sets up an inference to design (by a good soul) from the intelligible order of the cosmos.

Earlier in the same Bk X, he had noted just how old and how philosophically loaded evolutionary materialism and its appeal to chance and/or necessity are, drawing out consequences for law, government and community:

Ath[enian Stranger, in The Laws, Bk X 2,360 ya]. . . .[The avant garde philosophers and poets, c. 360 BC] say that fire and water, and earth and air [i.e the classical “material” elements of the cosmos — the natural order], all exist by nature and chance, and none of them by art . . . [such that] all that is in the heaven, as well as animals and all plants, and all the seasons come from these elements, not by the action of mind, as they say, or of any God, or from art, but as I was saying, by nature and chance only [ –> that is, evolutionary materialism is ancient and would trace all things to blind chance and mechanical necessity; observe, too, the trichotomy: “nature” (here, mechanical, blind necessity), “chance” (similar to a tossed fair die), ART (the action of a mind, i.e. intelligently directed configuration)] . . . .

[Thus, they hold] that the principles of justice have no existence at all in nature, but that mankind are always disputing about them and altering them; and that the alterations which are made by art and by law have no basis in nature, but are of authority for the moment and at the time at which they are made . . .

We see the wider setting and the more specific themes.>>

U/D May 14, to promote from 470 below and onward, a summary of kernel ID theory as a cluster of postulates — based on clips from the UD Resources tab:

ID as a Postulates based Scientific Framework

The theory of intelligent design (ID) holds

[–> key, evidence backed postulate, cf those of Newtonian dynamics and special then general relativity, thermodynamics and statistical thermodynamics, postulational cores can be brief but sweeping in impact]

that

[First, Evidence-backed Programmatic Postulate:] certain features of the universe and of living things are best explained [–> explicit reference to logic of abductive reasoning] by an intelligent cause rather than an undirected process such as natural selection.

ID is thus a scientific disagreement with the core claim of evolutionary theory that the apparent design of living systems is an illusion.

In a broader sense,

[2nd, Operational Postulate:] Intelligent Design is simply the science of design detection — how to recognize patterns arranged by an intelligent cause for a purpose.

Design detection is used in a number of scientific fields, including anthropology, forensic sciences that seek to explain the cause of events such as a death or fire, cryptanalysis and the search for extraterrestrial intelligence (SETI). [–> design oriented sciences. Signal to noise ratio in telecommunications is based on a design inference.]

[3rd, Empirical Warrant/Point of test or potential falsification postulate:] An inference that certain biological information may be the product of an intelligent cause can be tested or evaluated in the same manner as scientists daily test for design in other sciences.

ID is controversial because of the implications of its evidence, rather than the significant weight of its evidence. ID proponents believe science should be conducted objectively, without regard to the implications of its findings. This is particularly necessary in origins science because of its historical (and thus very subjective) nature, and because it is a science that unavoidably impacts religion.

[Evidence Corollary:] Positive evidence of design in living systems consists of the semantic, meaningful or functional nature of biological information, the lack of any known law that can explain the sequence of symbols that carry the “messages,” and statistical and experimental evidence that tends to rule out chance as a plausible explanation. Other evidence challenges the adequacy of natural or material causes to explain both the origin and diversity of life . . . .

Intelligent design [ID] – Dr William A Dembski, a leading design theorist, has defined ID as “the science that studies signs of intelligence.” That is,

[4th, Designs and Signs Postulate:] as we ourselves instantiate [thus exemplify as opposed to “exhaust”], intelligent designers act into the world, and create artifacts. When such agents act, there are certain characteristics that commonly appear, and that – per massive experience — reliably mark such artifacts. It it therefore a reasonable and useful scientific project to study such signs and identify how we may credibly reliably infer from empirical sign to the signified causal factor: purposefully directed contingency or intelligent design. [–> definition of design, note, abductive inference from observed sign to signified cause.]

Among the signs of intelligence of current interest for research are:

[Supplement, on evidence:] [a] FSCI — function-specifying complex information [e.g. blog posts in English text that take in more than 143 ASCII characters, and/or — as was highlighted by Yockey and Wickens by the mid-1980s — as a distinguishing marker of the macromolecules in the heart of cell-based life forms], or more broadly

[b] CSI — complex, independently specified information [e.g. Mt Rushmore vs New Hampshire’s former Old Man of the mountain, or — as was highlighted by Orgel in 1973 — a distinguishing feature of the cell’s information-rich organized aperiodic macromolecules that are neither simply orderly like crystals nor random like chance-polymerized peptide chains], or

[c] IC — multi-part functionality that relies on an irreducible core of mutually co-adapted, interacting components. [e.g. the hardware parts of a PC or more simply of a mousetrap; or – as was highlighted by Behe in the mid 1990’s — the bacterial flagellum and many other cell-based bodily features and functions.], or

[d] “Oracular” active information – in some cases, e.g. many Genetic Algorithms, successful performance of a system traces to built-in information or organisation that guides algorithmicsearch processes and/or performance so that the system significantly outperforms random search. Such guidance may include oracles that, step by step, inform a search process that the iterations are “warmer/ colder” relative to a performance target zone. (A classic example is the Weasel phrase search program.) Also,

[e] Complex, algorithmically active, coded information – the complex information used in systems and processes is symbolically coded in ways that are not preset by underlying physical or chemical forces, but by encoding and decoding dynamically inert but algorithmically active information that guides step by step execution sequences, i.e. algorithms. (For instance, in hard disk drives, the stored information in bits is coded based a conventional, symbolic assignment of the N/S poles, forces and fields involved, and is impressed and used algorithmically. The physics of forces and fields does not determine or control the bit-pattern of the information – or, the drive would be useless. Similarly, in DNA, the polymer chaining chemistry is effectively unrelated to the information stored in the sequence and reading frames of the A/ G/ C/ T side-groups. It is the coded genetic information in the successive three-letter D/RNA codons that is used by the cell’s molecular nano- machines in the step by step creation of proteins. Such DNA sets from observed living organisms starts at 100,000 – 500,000 four-state elements [200 k – 1 M bits], abundantly meriting the description: function- specifying, complex information, or FSCI.)

[(f) evidence of the fine tuned cosmos.] . . . .

Thus, ID can be framed on postulates, and we may draw forth from such that cells using memory structures storing coded algorithms and associated execution machinery are strong evidence of the design of cell based life. With Drexler, we are looking a bit at nanotech issues.>>

Food for thought and for clarification. END

U/D May 8th, to allow another thread to return to its focus:

>>THE FOLLOWING COME FROM THE LEAK CASE THREAD:

F/N May 7: As tangential objections to the design inference have been taken up (in obvious subject switching) I pose p. 5 from Sir Francis Crick’s March 19, 1953 letter to his son:

Crick’s letter

And, here is the protein synthesis process in outline:

Protein Synthesis (HT: Wiki Media)

Together with a summary of the information communication system involved, as outlined by Yockey:

Yockey’s analysis of protein synthesis as a code-based communication process

F/N, May 8: As the tangent continues, it seems a further illustration is advisable:

It seems more is needed, so here is how this fits into protein synthesis and the metabolic network and how we see prong height coding:

In for a penny, in for a pound, here is a video:

Notice, we are actually dealing with a storage register. Say, each shaft with pins is set for five positions, four elevated, one on the ledge. This is directly comparable to GCAT, and as the video shows there are five digits:

| X1 | X2 | X3 | X4 | X5 |

The key is encoded to the correct string of digits that in combination will open the lock, say 13213. The resting fully locked position is of course 00000.>>

U/D May 14: As a side chain appeared in another thread that is more appropriate here, I cross post a footnote added there:

It being now an obvious tactic to sidetrack non technical UD threads into ID debates (even where there is a thread that is live on the topic with relevant information, graphics and video) I will augment basic correction below by adding here a chart showing tRNA as a Drexler style molecular nanotech position-arm device:

We may expand our view of the Ribosome’s action:

The Ribosome, assembling a protein step by step based on the instructions in the mRNA “control tape”

As a comparison, here is punched paper tape used formerly to store digital information:

Punch Tape

We should tabulate”

The Genetic code uses three-letter codons to specify the sequence of AA’s in proteins and specifying start/stop, and using six bits per AA

In Yockey’s communication system framework, we now can see the loading [blue dotted box] and how tRNA is involved in translation, as the AA chain towards protein formation is created, step by step — algorithm — under control of the mRNA chain of three base codons that match successive tRNA anticodons, the matching, of course is by key-lock fitting of G-C or C-G and A-T or T-A, a 4-state, prong height digital code:

Yockey’s analysis of protein synthesis as a code-based communication process

Further to this, DNA has been extended with other similar monomers, and DNA has been used as a general purpose information storage medium for digital codes, apparently even including for movie files.

The point of this is, for record, to expose and correct how hyperskeptical objectors have inappropriately tried to deny that D/RNA acts as a string based digital information storage unit, that it holds algorithmic code used in protein synthesis, and latterly that tRNA acts in this process in the role of a position-arm nanotech robot device with a CCA tool tip, CCA being a universal joint that attaches to the COOH end of an AA.

Speaking of which, AA structure, with side branches [R] and chaining links, i.e. NH2-alpha Carbon + R – COOH:

F/N, May 14, it is worth the while to add, regarding layer cake communication architectures and protocols:

Where, underlying this is the Shannon model, here bent into a U to show how layers fit in, this also ties to Yockey:

A communication system

We may then extend to Gitt’s broader framework:

Gitt’s Layer-cake communications model

As an illustration, the ISO model:

OSI Network “layer-cake” model

Similarly, here is a layer cake view of a computer (network ports can be added):

These layers, of course, are abstract, only the physical layer is hardware we can see directly. Even for that, we cannot easily see all the design details for compatibility and function.

These may be compared to Yockey, to draw out the framework of codes, protocols and communication requisites.

U/D May 21, on illustrating one aspect of cosmological fine tuning:

Barnes: “What if we tweaked just two of the fundamental constants? This figure shows what the universe would look like if the strength of the strong nuclear force (which holds atoms together) and the value of the fine-structure constant (which represents the strength of the electromagnetic force between elementary particles) were higher or lower than they are in this universe. The small, white sliver represents where life can use all the complexity of chemistry and the energy of stars. Within that region, the small “x” marks the spot where those constants are set in our own universe.” (HT: New Atlantis)
Comments
F/N: Wikipedia's forced concessions on time:
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession [--> that is where energy dissipation and entropy enter, thus CTThD] from the past, through the present, into the future.[1][2][3] It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.[4][5][6][7] Time is often referred to as a fourth dimension, along with three spatial dimensions.[8] Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars.[7][9] Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.[10][11][12] [--> precising definition is difficult but we form the concept naturally through living in a CTThD] Time in physics is operationally defined as "what a clock reads".[6][13][14] [--> Onward, what is a clock, but a device that uses oscillatory or predictable trend processes to monitor, accumulate and indicate the lapsing of time locally, with particular reference to relativity and inertial frames of reference] The physical nature of time is addressed by general relativity with respect to events in spacetime. Examples of events are the collision of two particles, the explosion of a supernova, or the arrival of a rocket ship. Every event can be assigned four numbers representing its time and position (the event's coordinates). However, the numerical values are different for different observers. [--> hence, relativity] In general relativity, the question of what time it is now only has meaning relative to a particular observer. [--> this is extended to a cosmological time index as was already noted, in effect what a suitably located and constructed standardising clock would indicate since the singularity, which ties to the thermodynamic nature of time] Distance and time are intimately related, and the time required for light to travel a specific distance is the same for all observers, as first publicly demonstrated by Michelson and Morley. General relativity does not address the nature of time for extremely small intervals where quantum mechanics holds. At this time, there is no generally accepted theory of quantum general relativity.[15] Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second. Time is used to define other quantities, such as velocity, so defining time in terms of such quantities would result in circularity of definition.[16] An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. To describe observations of an event, a location (position in space) and time are typically noted. The operational definition of time does not address what the fundamental nature of it is. It does not address why events can happen forward and backward in space, whereas events only happen in the forward progress of time. Investigations into the relationship between space and time led physicists to define the spacetime continuum. General relativity is the primary framework for understanding how spacetime works.[17] Through advances in both theoretical and experimental investigations of spacetime, it has been shown that time can be distorted and dilated, particularly at the edges of black holes.

Sev, yup. Also, there is another theft going on, pennies used to count for something. Inflation. But on the main point, addition and subtraction here are vector operations for a 1-d vector space. 3 + 2 - x = 1, so x = 4 and -4 is a reverse direction to +. Yes, negative values have very useful real world implications once one accepts quantities based on size with direction. Of course there didn't orter be an x factor, which leads to a simple design inference with character implications.

KF writes, as a different topic than the one he and I have been discussing, "That there are no physically instantiated objects that are perfect hexagons etc does not change the validity of the abstracta etc.." I agree with KF on this one. Pure mathematics, abstract as it may be (and imaginary, to use Jerry's term), still is about valid things that exist as concepts. Tying this into our discussion, a countably infinite set such as the integers exists as a concept even though a countably infinite number of things can't be physically instantiated.Viola Lee

FH, models in the usual sense are not the same as frameworks of structure and quantity reflecting a cluster of key necessary entities found to be framework for any possible world. That said, that necessary status allows us to freely frame abstract logic model worlds with such entities and infer validly from them to our own world.

Let it stand clear that those who reject a beginning find themselves step by step forced to defend increasingly bizarre claims
Yes, most definitely. But you haven’t touched what these bizarre claims would be. You’re fixated on something no one is going to feel is an issue.
there is no coherent concept of a nine sided hexagon or a Euclidean square circle
There’s no example of a hexagon, circle or square in the real world. Anyway - back to work. The truth will not make any difference to anyone anyway.jerry

Jerry, a pink weightless elephant is an abstract concept and is quite real as that, just no physically actualised elephant can be weightless, as made of atoms. An 8-legges weightless elephant is a valid concept but elephants would normally be quadrupeds. By contrast there is no coherent concept of a nine sided hexagon or a Euclidean square circle. And more.

VL, the problem glided over is that if the actual past was without beginning, every member of Z- maps to a physically actualised year, which leads to spanning a cluster of years with order type w and cardinality aleph null. That is a structural problem that will not go away if one points to or symbolises years y1 and y2 and says once we make specific we can go on beyond the farthest back and keep going. Namely, the boundlessness of keeping going. This is part of why I have kept pointing to the ellipsis. As was already noted 3 years ago and beyond, the ellipsis counts. We are only warranted to speak of finite spans to the past, and to imply a finite limit as the alternative is an infeasible supertask of stepwise spanning a cluster of years of order type w. At this point, it is clear there will be no agreement but that is not because the logic of a claimed beginningless past is unclear. And not because such a suggestion would not directly lead to an infeasible supertask. Let it stand clear that those who reject a beginning find themselves step by step forced to defend increasingly bizarre claims. Meanwhile, I have plenty reason to suggest that the number line should be set in the context of the hyperreals. KFkairosfocus

there is no good reason why abstracta should not be real entities that are part of the framework of our world,
So you include pink weightless elephants too? How about the 8 legged ones? I’m being facetious to make a point. You are picking and choosing what you personally believe is relevant. But the choice is arbitrary and are not part of any actual framework. The closer they come the more useful they are but close is not the same as actual. Nearly all mathematics is based on concepts of infinity but we live in a discrete finite world. But again this has all been said before. The irony is that your assumptions are not necessary to make your basic point which I assume is that there is not an infinite past.jerry

Jerry, there is no good reason why abstracta should not be real entities that are part of the framework of our world, deep structures and quantities that are aspects of the logic of being. Yes, our physical representations are not exact, classically the sketches used as pictorial aids in Geometry; something highlighted to us at the opening of 3rd form Geometry. However, the algebras are quite exact. And here, I begin to think the fading of Geometry in school may be part of our problem. KFkairosfocus

KF writes, "And, has it suddenly become feasible to stepwise traverse finite stages of order type w?" There is no problem in traversing finite stages of a countably infinite set. Of course you can't traverse the entire set, but you can traverse any finite subset. Therefore, for any negative integer K a) you can traverse stages to 0, and b b) there is a smaller negative integer K -1 from which you can also traverse stages to 0, with just one more step.Viola Lee

Viola Lee I am just talking about pure mathematics, not time
Oh,"Pure mathematics" ...then has no relevance about the "pure quantitative realities" of our universe .But who made the sleight of hand from "pure maths" to "our universe math"?Lieutenant Commander Data

Math is the study of the logic of structure and quantity
But it’s in your imagination not the real world. There’s no actual correspondence to real world entities. For example, there’s no example of a line let alone an actual straight line in the real world. We can imagine one in our heads and assume the imperfect connection of dots is like one, but that does not mean it actually exists. Similarly with numbers. But you know this because it has all been said before. This is all to show infinity doesn’t exist. But I have shown you a much much better proof that infinity doesn’t exists.jerry

Jerry, I am echoing the definition that Math is the study of the logic of structure and quantity. KF PS, Integers and reals are vectors similar to complex numbers. The difference is, one dimensional.kairosfocus

All good then. Pro-tip: don't take me seriously either. Have fun... And when it's no longer fun, stop. ;) ETA. This was to Viola. PS Twelfth Night is a play I've seen a few times (different productions) at the RSC.Fred Hickson

He’s joshing with you
Actually, no. I’m serious about this and Viola Lee knows that. I just have some embarrassing observations that run counter to the conventional wisdom on mathematics. And I once was extremely well educated in advanced mathematics. And support anyone interested in a career in math. It’s an extremely useful discipline.jerry

VL, how are years AD and BC enumerated? Is it by accident that BC counts down and AC up? What is the import of arguing that K years BC will always be preceded by -- actual past on this assertion -- by k+1, k+2 etc without limit? What is the order type of such a set as compared with say Z-? And, has it suddenly become feasible to stepwise traverse finite stages of order type w? Where, if years BC do not amount to that order type is that not tantamount to implying that actual years past BC are finite and bounded? KF PS, Notice, too that if two years y1 and y2 are specified, the structure of a claimed beginningless past is such that the more remote in the past years onward will always exceed it without limit. Which underscores that such a claim impliestransfinite traverse of order type w. The relevant metric being count of years. Every time we specify y1 and y2 we specify a finite subset, with the context that there are ellipses beyond. Much more can be said.kairosfocus

I have no idea what the calendar has to do with the integers, other than years are one real-world application of using integers, as are seconds, weeks, and any other measure of time. But when I talk about the integers they are just uniform, discrete elements of the number system: there is no need to think of them as any specific unit of time as I am just talking about pure mathematics, not time.Viola Lee

I am mathematically correct about the integers, so I have the logic of structure and quantity supporting my position.Viola Lee
