The two are admittedly modeled as points, which works if you consider say their centers of gravity or their most-forward point. But by your assertion, do you mean that the tortoise is never at these intermediate points, only, the regions between? — noAxioms
Sorry to find a nit in everything, even stuff irrelevant to the OP, but relativity theory doesn't say this. In the frame of Earth, Earth is stationary. There's noting invalid about this frame. — noAxioms
Take the zero-point energy, for example. In relativity it corresponds to the cosmological constant (lambda term) or 'dark energy' of the Universe. Besides the fact that measurement for the 'dark energy' does not match the theoretical predictions for the zero-point (the cosmological constant problem), we here have grounds for challenging relativity, based on the lambda term, given we affirm the validity of quantum. — Nemo2124
The tortoise moves harmoniously even by infinitisimals, at the end, taking an eternity to reach the finishing line, but reaching it in the end (because of the summation of geometric series). — Nemo2124
We need a starting point here. Do we first take relativity to be valid or the absolute quantisation of space-time? Does the Planck constant suggest that there is a real fabric to space-time at the vacuum level? What is the nature of this fabric? These are questions that start to arise when we have a starting point, that is the discretisation of a space-time. In other words relativity has to make itself compatiable to quantum theory and not vice-versa. We just have to accept that the tortoise wins. — Nemo2124
Given an eternity and the fact that the tortoise keeps moving, I think that it will eventually cross any line that is set at a finite distance in the race. — Nemo2124
Physical space is not "infinitely" divisible like abstract space. Like most, this paradox is merely apparent – in this case it's derived from confusing the physical and abstract. — 180 Proof
Sticking to the paradox, I don't think that Achilles can ever reach the tortoise, unless it reaches some sort of Planckian limit in distance and suddenly quantum leaps to become 'the winner'. That suggests that space-time is discretised, that you do reach a limit in physics that does not exist in mathematics. — Nemo2124
In the end, quantum leaps aside, although the tortoise moves at an imperceptibly and almost infinitely small pace, it still keeps moving and eventually will cross the line, given that there is no time limit. This seems to accord to what we perceive in reality, we are somewhat subordinated to nature's ultimatum. — Nemo2124

To me, trial and error is a method of problem-solving, such that the solving of the problem is its entailed end. — javra
Trial and error in no way overlaps with unintended, and hence accidental, discovery: if one, for example, accidentally discovers a valuable jewel underneath one’s sofa while cleaning one’s room, there was no trial and error involved in the process; on the other hand, trial and error, because it always seeks an end, is always purposeful, intentional, such that when the problem is solved by this approach, its so being solved is not an unintended accident. — javra
on the other hand, trial and error, because it always seeks an end, is always purposeful, intentional, such that when the problem is solved by this approach, its so being solved is not an unintended accident. — javra
As to evolution being a trial and error process, I then find this to be a fully metaphorical application of the phrasing. Evolution is not a sentient being; and thereby cannot as process of itself intentionally problem-solve anything, much including via any trial and error means. More bluntly, what problem might evolution be intending to solve? This is not to then claim that evolution is not in large part a teleological process, but evolution is not the type of teleological process which applies to the intentioning of individual agents (and only to the latter can trying and failing and then trying again, this with a set goal in mind, apply). — javra
In an Aristotelian model of things, “optimal eudemonia” (what you’ve termed “happiness”) is everybody’s ultimate end at all times – and not just for he who has agreed to uncover rocks for someone else. It will hence equally apply to he who wants the rocks uncovered for his own hidden purpose by the person who’s agreed to do so. And this Aristotelian conception of the ultimate end is only the most distal (distant) telos of an otherwise potentially innumerable quantity of teloi any person might be intending at any given time. And in so being, though one might get closer to it at certain times rather than others (when one is more at peace, or else joyful, for example), this ultimate telos of “optimal eudemonia which can only translate into a perfected eudemonia” is the most unreachable telos of all teloi out there. The most difficult, if at all possible, to actualize. It here drives, or else determines, all other teloi, this at all times, but it itself cannot be obtained for as long as any personal suffering occurs or is deemed to have the potential to occur. This includes some personal interpretation, granted, such as in what "suffering" signifies. But I still find it to be the only coherent way of understanding 'happiness as ultimate end'. — javra
Secondly, why did the person who’s agreed to turn over rocks so agree in this first place? — javra
I'm not sure about that. The potential energy between two objects *increases* with space. A ball 2m above the surface of the earth is said to have more potential energy than a ball 1m up. So perhaps it all adds up. — flannel jesus
I for one don't find reason to assume the observer is separate from the actor (here specifically as pertains to the act of choice making). — javra
In the example you provide, on the other hand, I as the actor must for whatever (I uphold end-driven) reason first comply with your request if I am to at all act as you wish on your behalf. Once I so comply, then my actions will themselves all be end-driven - this not by your want to engage in trial and error actions whose end is unknown to me - but by my own then actively occurring want to successfully end up so "turning over all the rocks in a specific area". This in itself then being the end which teleologically drives, and thereby motivates, my actions.
So, at least in the example provided, I still find all activities to be end-driven and thereby purposeful. — javra
Are you then suggesting that intentioning can occur in the complete absence of any intent? Such that X can consciously intend some outcome Z despite not being motivated by any intent/end - an intent/end which thereby equates to Z's successful actualization at some future point in time? — javra
But, again, I don't find reason to entertain what you've so far suggested. — javra
Neither of these, however, refute the purposiveness of each individual agency of a total mind concerned. — javra
As to trial and error processes, I can so far only disagree with such being purposeless. — javra
So doing would then be evolutionarily unfit. And so it would not then be as common an activity in lifeforms as it currently is. On the other hand, whenever we as conscious humans engage in trial and error processes it is (as far as I know) always with a purpose in mind. — javra
While I grant that our unconscious doings might at times seem random to us, I can so far find no reason to entertain that any intention-devoid agency can occur. I acknowledge the possible reality of randomness in relation to agency at large, but will deem it to be the outcome of discordant agencies, each intention-endowed, whose interactions results in outcomes unintended by any. This be the agencies individual humans or else the individual agencies of a singular total human mind. — javra
Perhaps it does have an effect on the void. Space expands and light loses energy as it travels through expanding space. Maybe space expands proportionally to the energy lost to it — flannel jesus
Of course this is he same as the amount of energy being constant while the amount of energy available for work decreases over time. — Banno
What about friction, heat loss, things like that? When a machine loses energy, it doesn't just lose it into the void, it gets transferred to other things in its immediate environment. — flannel jesus
Can you think of a different reason why perpetual motion machines would be impossible? — flannel jesus
Whereas the conservation laws are metaphysical and true and helpful, determinism is metaphysical and potentially false and not helpful. — Banno
Having read your entire post, do you then find it fair for me to characterize the duality you are addressing as a duality between an illusory conscious I-ness and a real somnio-conscious I-ness? And if it is a fair interpretation, that you then interpret the real somio-conscious I-ness to occur while the waking conscious I-ness is also occurring – only that the former is unconsciously occurring relative to the latter? Or is this not quite right? If it’s not correct, then I still don’t quite understand what do you intend to express by “duality” of I-ness. — javra
To first define “agent”, to me it is any (at least relatively unified) identity which holds agency. In turn, also in keeping with common place notions, “agency” to me is the ability to accomplish (more explicitly to accomplish some end) and hence to do or undergo something - thereby meaning “the capacity, condition, or state of exerting power (“power” here in the strict sense of “ability to do or undergo something”) and, therefore, the capacity, condition, or state of engaging in actions (i.e. in this context, of intentionally doing things)”. — javra
In these latter contexts, then, the addressed agent is what William James terms the pure ego (the knower of one’s own total self) – rather than the empirical ego (the total self which is known). — javra
Having roughly addressed what I reference by the term “agent” (again, that which holds agency as previously defined), I’ll again affirm that I interpret a total human (or else relatively developed; e.g. birds, mammals, etc.) mind to be an almost literal commonwealth of agencies – which are sometimes partly discordant and sometimes fully unified in at the very least that which they intend as agencies. It most certainly won’t sound right due to the connotations which we’ve been habituated to understand by the term “agent” (this being one reason why I find the need for new terminology to address this in my own philosophical endeavors) but, when looking at the definition of “agent” that I previously provided, one could then appraise each and every distinct agency of a total mind to be a distinct – though transiently occurring – agent, replete with its own pure ego of sorts that apprehends and reacts to at least certain phenomena. — javra
Aye, it can indeed get very complex, agreed. To my mind at least, consciousness and unconsciousness are at all times interconnected, hence never in any way divided, and perpetually influence each other via top-down processes (formal causation in Aristotelian terms) and bottom-up processes (material causation in Aristotelian terms (which is not to be confused with what we today construe to be “mater”, as I so far believe you very well know [Aristotle, for example, gives the example of letters being the material cause of syllables (for syllable are made up of letters) or else the example of parts (say the ideas from which a paradigm is constituted) being the material cause of the whole (here, the paradigm of, say, biological evolution itself]). — javra
Ok. No one seems to have noticed this ground-breaking revelation. — Banno
Conservation of energy is neither falsifiable nor provable, and so not empirical, and yet still a part of physics. — Banno
For you, are conservation laws facts?
You can't prove that energy is conserved in every case, since not every case is available for you to check. Nor can you disprove it - if you came across a perpetual motion machine that seemed to be breaking the conservation law, you might hypothesis that it is somehow drawing energy frome elswhere in the universe...
SO, is conservation of energy a fact, or a bit of metaphysics?
an hour ago — Banno
OK. I did however clearly express "the somnio-conscious 'I'". I don't find how consciousness and somnio-consciousness can co-occur to thereby present a duality of I's. I, for example, can still vividly recall certain dreams and nightmares I've had decades ago: to me, I am the same I I was in these dreams and nightmares as a first-person point of view (with differences in my empirical ego, contexts, etc., of course): same first-person perspective regarding otherness, same affinities and aversions, etc. Hence, to me, a continuity rather than a duality of I-ness. — javra
I can see what you mean, but I myself don't subscribe to the unconscious mind being an agent (a unified agency). Again, I find reason to believe that the unconscious mind is constituted of a plurality of sometimes discordant agencies, themselves always changing. As one example, when awake and experiencing a pang of envy one can at the same time likewise experience one's conscience influencing one against becoming envious oneself: here there will then be two distinct agencies that are antagonistic to each other, each emerging from one's unconsciousness, each attempting to influence one's future course of action or of personal being. This as one example of how the unconscious mind can well consist of a plurality of discordant agencies. — javra
I'm not intending to engage in debates about this. What you here say indeed reminds me well enough of many a Hindu interpretation of atman, "witness consciousness". Yet, myself, I'll heavily lean toward this same consciousness being that which actively judges which alternative is optimally beneficial and should be manifested - this at expense of all other alternatives, i.e. of all other possible courses of action or of manifestation which then become rejected - and thereby chooses. In my own understanding, then, the agent (the conscious mind) always holds responsibility for the choices it itself makes, this in accord to its own judgments. — javra
physics has come a long way since newton. Banno is most probably thinking about QM when he says that. — flannel jesus
Indeed, the presumption that physics is deterministic is almost certainly mistaken. — Banno
Thus interpreted, for various reasons (some of which I'll try to specify), I don't interpret the unconscious mind as having its own non-manifold unity of a first-person point of view; in other words, its own "I". — javra
I personally believe that in dreams the somio-conscious "I" is constituted of a lesser quantity of yet unconscious awareness-endowed agencies, a sleeping "I" which then interacts with fully unconscious agencies via imaginary phenomena that are mostly intended by these unconscious agencies of mind. — javra
I take it that here and what follows you found what is real based on that which is permanent rather than transient. But then I don't find reason to presume that the agencies of awareness of the unconscious mind are themselves in any way permanent either — javra
If the One ontically is a fixed and unmovalbe end of being, and tf the grand telos to being is therefore to eventually become one with the One, then the evolution of consciousness will be derived from this premise to be a stepping stone toward this very finale. Of course things could get far more complex, but, in short, consciousness can be viewed as a manifestation of a cosmic will toward unity of being. And it's only in this latter type of perspective that I can find any meaningful explanation for consciousness's occurrence and purpose. — javra
OK, that all briefly outlined, we as consciousnesses do not create the alternatives which we as consciousnesses are aware of. These competing alternatives for what will be are all (at least typically) brought about by our unconscious portions of mind. My further interpretation is that our unconscious mind comes to an uncertainty as to how to travel onward and, so, presents to us as a conscious awareness these alternative courses. In essence, our unconscious volition is no longer unified but fragments into different volitions regarding what should be done - each alternative being in effect what a fragment of the unconscious believes to be the optimal path. We as conscious awareness then vote on which path to take, and our unconscious (typically) then accepts our vote as a determination of which alternative is to be pursued at expense of all others which then become denied. This is (or at least nicely conforms with) the terminology of Romanian Christian Orthodoxy wherein free will is termed "liber arbitru", the free arbiter - such that we as conscious awareness, as the "I", are the free arbiter. — javra
At any rate, whenever we choose between alternatives, this with or without free will, we necessarily interact with the disparate volitions of our unconscious mind so as to resolved disagreements therein. (Yes, sometimes ultimatums and the like are presented to us from without, but even then we only become aware of, ultimately, what our own unconscious mind makes available to us.) — javra
1) Free will as a concept arose as a response to the theodicy. AFAIK this is just true. As a concept it was never meant to make sense of the human on its own terms, it was meant to make sense of our relationship with god and the world's evil. — fdrake
This view of decision is inimicably Christian. The concept of will must be inherently unconstrained so that the horrible crap in the world can be our fault. That's what it's for. Free will gives humanity legislative authority over our own evils. — fdrake
To conjoin this with what I was previously mentioning, my own interpretation is that dreaming is a form of sheer imagining, only that in dreams the unconscious mind agentially determines most of what is being imagined, this rather than the conscious mind's volition as is typically the case when we are awake and willfully imagine things (things which in common speech are said to be seen by us with the mind's eye). When we willfully imagine a house while awake, we do it with a conscious intention. I personally believe that in dreams the somio-conscious "I" is constituted of a lesser quantity of yet unconscious awareness-endowed agencies, a sleeping "I" which then interacts with fully unconscious agencies via imaginary phenomena that are mostly intended by these unconscious agencies of mind. In contrast, a typical awake "I" would then be a non-manifold unity of agential awareness which is itself constituted from far more otherwise unconscious agencies of mind. It gets difficult in succinctly explain but it does coherently tie in with the view I presented to Patterner here - this regarding how the conscious mind is a convergence of certain aspects of the otherwise unconscious mind. — javra
Maybe tangential, but to me it also accounts for the how and why of the waking "I" dissolving into non-occurrence when falling asleep and then re-manifesting as a somnio-consciousness when we dream: Basically, the waking "I" dissolves, or if one prefers fragments, into its constituent unconscious agencies which are otherwise unified, and thereby transiently vanishes; then, in dreams, the sleeping "I" reemerges but in what most often is a qualitatively lesser form; upon awakening, the waking "I" then is reunited from its constituent unconscious aspects. Because of this the waking "I" can sometimes remember what the sleeping "I" experienced during dreams, but the sleeping "I" most always doesn't have memories of waking "I"'s experiences. — javra
Want to draw attention to this typically being so only upon our awakening. When we are experiencing the dream first hand, we don't typically at that juncture hold an awareness of the dream being irrational. It merely is; and we find ourselves doing what we do in it.
It could be the case that the reasoning of most dreams is fully metaphorical with meanings understood by at least certain aspects of our unconscious mind but not by our awakened state of rationality. This, for one example, as the surrealists of a century past more or less maintained. — javra
Most definitely. The visual appearance of an imagined or daydreamed house, for example. Imaginings and daydreams are typically under the full sway of conscious volition, but in cases of hallucination, for a different example, a person can see a hallucinated house - difference from the former being that here the unconscious mind controls the imagining without any sway from consciousness's volition. Such that in more extreme mental disorders the consciousness will presume the hallucination to in fact be an integral aspect of the external world. And everthing just stated can readily apply to sensory experiences other than that of vision (smell, taste, touch, or sounds (such as that of hearing voices)). — javra
To add to this muddle of views and information - and as much as materialists will snide and scoff at this - there also are notions such as that of Jung's collective unconscious. When entertaining such notions, not only can one obtain things such as meaningful synchronicities, but it can also allow for the possibility that at least some dreams in at least some people are influenced by the collective unconscious.
Anecdotal but true: one of my grandmas repeatedly had premonitions via her vivid dreams. Hard to explain even one of them in succinct manners, but the point is she would inform us of what will be, and it would then occur as she predicted from her interpretation of here dreams. One can question or deny the verity of this, but for me, who grew up with her, to claim that all her dreams and predictions were mere coincidence would verge on absurdity.
Maybe this is too far off topic. But I did want to draw attention to the possibility that some dreams might be more than merely the 'irrational activities of one's own physical and fully autonomous brain,' or some such. — javra
There is a so called real so called I. The body. Although that is affected by the creativity, feeling a positive bond with the "I", the feeling is real, but the object of the bond, the "I" is a small-c creation. — ENOAH
1. Dream X is caused by physical event Y. (the full-bladder explanation)
2. Physical event Y is caused by dream X. (the kicking explanation)
3. Neither dream X nor event Y can be said to cause the other. The relation between X and Y is not a causal one, but rather one of supervenience or grounding.
As is now apparent, this is a little microcosm of the whole mental-causation problem. But I offer it because it’s curiously amenable to analysis, and makes me wonder whether any sleep researchers have actually used brain scans to look into this. — J
If I said dreams are autonomously moving signifiers called out of a
storage in memory, with no central agent, you would consider the arguments against that, but generally, you'd accept the possibility. — ENOAH
I agree; "universal subjective field" is something we can say, but we don't really know what we are talking about, and so it has no explanatory power. It's a kind of confabulation, hand-waving. — Janus
In modern physics theory, one can picture all subatomic particles as beginning with a field. Then the particles we see are just localized vibrations in the field. So, according to quantum field theory, the right way to think of the subatomic world is that everywhere- and I mean everywhere- there are a myriad of fields. Up quark fields, down quark fields, electron fields, etc. And the particles are just localized vibrations of the fields that are moving around. Theoretical physics simply imagines that ordinary space is full of fields for all known subatomic particles and that localized vibrations can be found everywhere. These fields can interact with one another, like two adjacent tuning forks. These interactions explain how particles are created and destroyed – basically the energy of some vibrations move from one field and set up vibrations in another kind of field.
So, here’s a possible tally for the number of quantum fields:
2 (quantum electrodynamics [QED]) – the electron field and the electromagnetic aka photon field
17 (Standard Model [above])
24 (Standard Model including all gluon colors) — 12 fermion fields and 12 boson fields
25 (24 + Graviton)
Even more if include anti-particles?
Even more if include handedness?
And tariffs are off again, partially, until April, maybe.
This seems to be a good way to drive away any kind of investment since no long-term planning is possible. — Echarmion
You are welcome to produce an alternative definition of "field" that does not invovle a value at every point in a space.
But if you do, you will not be able to claim that your field is anything like an electric, gravitational or other physical field. — Banno
So far as explanations go, saying that something is an example of a field exactly becasue it does not meet the criteria for being a filed is... odd. — Banno
Also something less than opinion: When one sees a house in a dream, one does not see the house due to photons being picked up by the retina and thereby due to retinal input. — javra
I have no way to prove this opinion, but I find it likely in part on grounds that people who do not sleep for long periods of time don't only become extremely exhausted but also tend to have psychotic breaks, i.e. go insane, which seems plausible if procedural memory is not properly processed. I also don't personally know of a more plausible evolutionary explanation for why REM dreaming evolved to begin with given that mammals at large as well as birds exhibit REM sleep. — javra
We all experience our dreams uniquely in many a way, but I've certainly heard of cases wherein the dreams of a sleeping person were affected by that which surrounded them in the external world, including sounds and smells, even though they were not at the time in any way conscious of what was taking place in the external world. Then, also, there's the alarm clock, which at first unconsciously wakes you up into consciousness from sleep and the dreams therein had. (A good shove can also due — javra
That said, we do all experience dreams differently. It is not utterly uncommon for some humans to have dreams in which they fly through air at will. I too have had such dreams growing up. I remember them being rather serene and euphoric for the most part. And I distinctly remember being therein endowed with a supra-human capacity of will, hence volition, to travel through the air as I wanted simply by so willing it. In dreams such as these, there is certainly found a free will (or at least a sense of free will for the free will deniers) in which one chooses as one pleases between alternatives. In this case, alternative paths of motion and different destinations. — javra
Indeed. It's not our conscious mind that makes us sleep. Our conscious mind often fights it in any way it can. Eventually failing. — Patterner
I don't think this is the case, not when one regards seeing as necessarily consisting of input from the retina. I think the way we see things in dreams is often a more vivid form of the way we see things when daydreaming or imagining. Only that when dreaming the unconscious mind assumes far greater agential control over what is in thus manner seen. — javra
It gets tricky here, in part due to often numerous ways in which terms can get understood. But, in principle, though we are not of a waking state consciousness while dreaming, we as a first-person point of view (as consciousness in this sense) are yet present in our dreams. Not only that but, as a somnio-consciousness (a term which I coined that I think nicely enough expresses our dreaming consciousness), we almost always yet have some degree of agential power (i.e., ability to accomplish) - hence, some degree of voluntary, rather than involuntary, volition. With one possible extreme of this degree of dreaming volition being that of lucidly dreaming. — javra

After a limiting distance (about the size of a hadron) has been reached, it remains at a strength of about 10000 N, no matter how much farther the distance between the quarks.[7]: 164 As the separation between the quarks grows, the energy added to the pair creates new pairs of matching quarks between the original two; hence it is impossible to isolate quarks. — Wikipedia
