    The dog does not recognize the sound of it's human's car.creativesoul
    Sure he does. Even the dumbest dog knows the sounds and smells of its people and their stuff.
    The dog, after being reminded of past events - by virtue of being amidst much the same spatiotemporal events - begins to form, have, and/or hold expectation that the human will be there. In doing so the dog begins getting anticipatory excitement in a happy sort of way due to the lifelong loving connection the dog and human have.creativesoul
    You're using more words to describe: dog expects human's arrival. 'Spatiotemporal' - yes, he knows where and when. I can't characterize that as even one of the multitude of alternate explanations.
    I'm not saying that the dog's behavior is not rational. I would say that it most certainly is.creativesoul
    Yes. So, then...?
    It is only after becoming aware of the fact that we can be wrong about stuff, that we can become hopeful - in the face of that uncertainty.creativesoul
    That's a pretty big bold statement about a wide-ranging emotion! What has our own fallibility to do with hope? It's not as if we had, before discovering our own fallibility, been convinced of being in control of the universe.
    Compared/contrast that with autonomous anticipation and/or expectation without such metacognitive reservation.creativesoul
    You mean humans never rationally expect something that usually happens to go on happening on schedule? When a human goes to work on Monday morning, he doesn't merely hope, but quite reasonably and confidently expects his workplace to stand where it has always stood and function as it has always functioned. If it's lifted up by an alien police force and transported to the moon, he discovers his own fallibilty. If he and the workplace survive the incident, thereafter, he only hopes to find it in the usual place.
    If the dog's human is taken to hospital during the day and doesn't return home for a week, the dog's reasonable expectation is reduced to hope.
    This mistakenly presupposes that you are somehow privy to my fear(s)?creativesoul
    Nah, just citing a vague general human-centric fear. It was huge in the sciences for a century. the word 'looms' triggered it.

    What people say is not always candid, insightful or comprehensive. I know of no effects without a cause. It sounds as if they 1. are not aware of or 2. do not wish to investigate or 3. assume you already know the sequence of experiences that have contributed to this particular response to an anticipated and repeated situation.
    Knowing what time a particular person is expected to arrive is to pick that time out from the rest. The dog does not do that. The dog knows when the human is about to arrive, and it is perfectly rational in doing so... but it does not know what time the human is expected to arrive.creativesoul
    I just don't follow the distinction here. Are there discreet points in the continuity of time that we have to identify and choose among? What increments, and how aware do we do have to be of choosing one? Or do we experience the passage of time as fluid, and of which we are sometimes keenly aware and sometimes lose track? I don't see how a dog should have to 'pick out' an item of time from among a group of similar items, as if it were a toy in a pile of toys. To me, minutes all look and pretty much alike; I could not tell them apart except by the events that take place during their passage.

    But then, as you say, I don't understand your arguments. Logically, then, I should stop responding to them. I don't know how to disengage without seeming rude.

    I wanted to mention something prior to retiring for the night.

    When I said "language less" I meant without naming and descriptive practices. There is no clear lines to be drawn between language less creatures and our pets, for they are not language less. Not at all, actually. There's good reason domestication changes animals drastically, aside from the shrinking of the gene pool which is the function of the aim of breeding for specific traits.

    There's overlap between language less animals and us. Our pets.

    This overlap matters here, in these sorts of discussions, for not all dogs and cats and birds have drawn correlations between our language use and other things. Some have. Pets are socialized by us with us. It matters. Language has helped, as best I can tell, in helping to provide better means for pets to become rational to a greater extent than their cousins.

    But you did say that Thomas Nagel, atheist though he might profess to be, should be categorised along with 'that crank' Alvin Plantinga, and The Discovery Institute, which is an Intelligent Design organisation. The implication is that you think Nagel and Plantinga's arguments against evolutionary theory are based on religious ideology and science denial, that you lump them all together as being a form of creationism or intelligent design. In actual fact, all three are very different. Thomas Nagel never appeals to intelligent design or belief in God - he says he lacks any 'sense of the divine'.

    wonderer1

    None of that is relevant, though. His argument is epistemological, about the nature of knowledge. It is of the kind described as 'transcendental arguments'. Transcendental arguments seek to demonstrate the necessary preconditions for the possibility of some experience, knowledge, or exercise of reason. They typically follow this form: if a belief is plausible, then certain conditions must be met for it to be coherent and intelligible.

    Plantinga argues that if both naturalism and evolution are true, then the probability that our cognitive faculties are reliable is low. If our cognitive faculties are unreliable, then we have a defeater for any belief produced by those faculties, including the belief in naturalism and evolution. This creates a self-defeating situation for the naturalist.

    The basis on which he says that, is that naturalism typically holds that all events, including mental events like beliefs, are the result of natural (e.g. neurological) causes that can be studied and explained by the principles of natural science (such as neurology). This form of causation is often referred to as efficient causation, where one event (the cause) brings about another event (the effect) in accordance with physical or natural laws. In this view, mental states, including beliefs, are fully determined by physical processes in the brain, which are themselves the result of evolutionary pressures and biological mechanisms. Those who hold that the mind is identical with or a product of the brain or neural processes are obliged to hold this view. It is made explicit in the arguments of those such as Daniel Dennett.

    In contrast, logical causation refers to the relationship between propositions where the truth of one proposition logically necessitates the truth of another. For example, if "All humans are mortal" and "Socrates is a human" are true, it logically follows that "Socrates is mortal" must also be true. This form of causation pertains to the realm of reason and logic rather than to observable physical processes. It governs how conclusions follow from premises in a rational argument, and is independent of physical causation.

    What I've been arguing in this thread, is that the human faculty of reason differentiates humans from other species, because it enables humans to 'see reason' in that second sense (i.e. grasp logical inference.) That general lineage of argument has a very long pedigree, going right back to Plato and his predecessors.

    I will add, there have been many developments in naturalism such that it no longer is susceptible to this argument i.e. Deacon's 'absentials', Vervaeke's 'extended naturalism' among others. But the case can certainly be made against the kind of neo-darwinian materialism that Dennett and Dawkins advocate.

    I might add, whatever occurs within a social species, is a completely separate matter to what evolves according to natural selection. That only operates over much larger time-periods, and refers to the process of speciation. Certainly culture and human capabilities develop, but h.sapiens have not evolved significantly since their early forbears first appeared.

    It addresses this gloss on your part:

    If you want to provide a more fleshed out account of this aspect of Plantinga's argument, I'll address that. In the meantime...

    As I said, Plantinga doesn't consider the role of communication among members of a social species in making his case. So Plantinga's claim is that:

    P(R|N&E) is low
    (I.e. the probability that our cognitive faculties are reliable given naturalism and evolution is low.)

    However, in order for Plantinga to address a scientifically informed position regarding the reliability of our cognitive faculties he needs to address a more complex scenario than he actually does. We can say that to be taken seriously Plantinga needs to address:

    P(R|N&E&S)
    (The probability that our cognitive faculties are reliable given naturalism and evolution and the evolution occured in a social species.)

    However, in order to make that case Plantinga would need to establish that truth conveying communication occurring amongst members of the social species would do nothing to increase the reliability of the cognitive faculties of members of that species, as compared to being a feral member of the species without social interaction.

    It's pretty ironic that an educator like Plantinga, needs to ignore the possibility of members of a social species educating each other and passing down culture, in order for his argument to superficially appear to work.

    and also, Aristotle's 'De Anima', translated as 'On the Soul'. I love the connection between Anima, Animal, and Animated.Wayfarer

    Aye. Me too very much so. To be fair, Aristotle spoke in Ancient Greek whereas "anima" "animal" and "animated" are Latin based. But the associations are fairly blatant to understand, at least from where I stand.

    A controversial thought, but if incorporeal beings of far grander stature - here thinking of polytheistic deities or else angels and archangels - were to be, what else would they be but more universal animas (souls) whose animus (mind) would be that much more evolved than any human's? Hence, if one were to entertain a great chain of being, it would start with the anima of bacteria or thereabouts and progress onward through the anima of humans into animas whose bodies of Logos would consist of non-physical Logos. No stark metaphysical divides anywhere to be found, just differences of degrees that then result in classifications of different kinds. This difference in kind amid an every fluid scale of degrees being in keeping with one nature of Logos being that of ratio-ning one something from the other.

    This, of course, is just one hypothetical to be found among many others - that of an utter non-spirituality included. But I'm here intending to draw attention to the realty that there needs to be no sharp metaphysical divide in being/anima/psyche anywhere from bacteria all the way to deities in order to entertain views such as those professed by many a spiritual reality, both Western and Eastern.

    Not sure how this thought will fly hereabouts. For the record, I'm not here endorsing any theology, but I am endorsing an absence of sharp metaphysical divides between all "animated" beings that coexist. And that this can just as easily apply to materialist interpretations of biological evolution as it can the concepts regarding the great chain (or, more aptly, ladder) of being. But, hopefully, I'm just preaching the the choir in saying all this.

    What is needed is engagement of a particular kind, so that one can grasp that animals in many ways will engage with us in many (but not all) of the same ways that we engage with other people.

    [...]

    That's very vague, but I'm trying to gesture at the idea that this is not just a matter for abstract reason. It's about how to live with beings recognizably like us. After all, that's how we come to treat people as people and not "just" animals".
    Ludwig V

    ... else how we come to understand that we ought not treat any other group of people as sub-human animals ... neither granting leeway to those who deem this to be so on "Nature-given" grounds or on "God-given" grounds, for both streams of reasoning leading to this same mentioned conclusion can, when more impartially addressed, only be utter bullshit. Black and Whites, for one example, being equally evolved not just biologically but also in their intellectual abilities - socioeconomic constraints of the current world aside.

    All this maybe being a different set of issues for a different thread. But I very much liked your post. Thank you for it.

    Again, it doesn't address the evolutionary argument against naturalism. He doesn't say that we're incapable of communicating, or that we can't convey information by speaking to one another. For that matter, many creatures other than humans communicate. Bee dances communicate where flowers are. Many birds and of mammals convey warnings or indications of food sources. But then, none of those involve truth claims, as such. They display behaviours which can be understood in terms of stimulus and response. Note that such behaviours are 'reliable' in that bee dances and meerkat alarm calls really do indicate where flowers are or that danger is approaching. The evolutionary argument is rather about judgements of truth.

    The argument is that naturalism maintains that mental events such as beliefs are the result of natural (e.g. neurological) causes that can be explained by the principles of natural science (such as neurology) - in other words, instances of efficient causation, where one event (cause) brings about another event (effect) in accordance with physical or natural laws. In this view, mental states, including beliefs, are determined by physical processes in the brain, which are themselves the result of evolutionary pressures and biological mechanisms. Whereas, reasoned inference works by different principles, relying on the relationship between propositions where the truth of one proposition logically necessitates the truth of another. So it's of a different order to physical causation - it transcends it.

    That is the thrust of the argument, and so far, I fail to see how your 'social species' response actually addresses it.

    I wonder how you know this. Or what difference it makes to rational thinking.Vera Mont
    I know how you and I know what we expect. By introspection, whatever that may be. How do other people know what you and I expect? By our behaviour. So I'm happy to say that the dog knows what they expect - and want and so on. So what might ground the claim that dogs don't have introspection? Well, they can't do anything that could differentiate between expecting X and knowing that one expects X, because they don't have the language skills to articulate it. It's just one of the knotty problems that come up when you are extending the use of people-concepts to creatures that lack human-type languages.

    When but not what time. Because he doesn't know the names humans have artificially given the hours and minutes of the day. Okay.Vera Mont
    But the train arrives at 5 pm. If we're happy to say that the dog knows when the human is about to arrive, why are we not happy to say that the dog knows the 5 pm train is about to arrive? Suppose the dog has learnt to read the station clock or at least to get up and start some preparatory tail-wagging when the clock says 5 - are you sure that they are incapable of that? If they can learn to associate a bell with the arrival of food, I think there's no way to be sure.

    My point is this. If one focuses on a specific case - which is a good thing to do, and much, much better than hasty generalizations - there will always be many possible representations of exactly what the dog knows/believes/expects. But if one sees that one case in the range of the dog's life, it will normally be possible to narrow down the possibilities. And one can get a bit further by indulging in thought-experiments, which will at least allow one to understand under what circumstances one might distinguish cases that seem utterly indistinguishable so long as one focuses on just the one event. But unless something important hangs on the issue, it will be tedious work, and one will be disinclined to pursue it unless it matters.

    Why should one explanation preclude the other? Another point is that most of our reasoning is inductive or abductive, where there is no logical necessity in play at all.Janus
    Good question. Isn't the issue that they do seem incompatible. We can express this in more than one way. They are different language games, different categories, different perspectives. At any rate, they seem incommensurable. Yet we know that a physical process can result in a logical conclusion. If it were not so, computers would not work. Indeed, if it were not so, calculation by pen and paper would not work, either.

    No. You seem confused, and are mixing bits of arguments against physicalism into your 'paraphrase'. The EAAN isn't an argument against mind/body physicalism.

    On page 313 of Where the Conflict Really Lies Plantinga writes:

    The basic idea of my argument could be put (a bit crudely) as follows. First, the probability of our cognitive faculties being reliable, given naturalism and evolution, is low. (To put it a bit inaccurately but suggestively, if naturalism and evolution were both true, our cognitive faculties would very likely not be reliable.) But then according to the second premise of my argument, if I believe both naturalism and evolution, I have a defeater for my intuitive assumption that my cognitive faculties are reliable. If I have a defeater for that belief, however, then I have a defeater for any belief I take to be produced by my cognitive faculties. That means that I have a defeater for my belief that naturalism and evolution are true. So my belief that naturalism and evolution are true gives me a defeater for that very belief; that belief shoots itself in the foot and is self-referentially incoherent; therefore I cannot rationally accept it. And if one can’t accept both naturalism and evolution, that pillar of current science, then there is serious conflict between naturalism and science.

    Plantinga is not making an argument against physicalism. In fact Plantinga thinks everyone has a God detector organ. (Although sadly, yours and mine are broken.)

    In Calvin's view, there is no reasonable non-belief:

    "That there exists in the human mind and indeed by natural instinct, some sense of Deity [sensus divinitatis], we hold to be beyond dispute, since God himself, to prevent any man from pretending ignorance, has endued all men with some idea of his Godhead…. …this is not a doctrine which is first learned at school, but one as to which every man is, from the womb, his own master; one which nature herself allows no individual to forget.[2]"

    Jonathan Edwards, the 18th-century American Calvinist preacher and theologian, claimed that while every human being has been granted the capacity to know God, a sense of divinity, successful use of these capacities requires an attitude of "true benevolence".[citation needed] Analytic philosopher Alvin Plantinga of the University of Notre Dame posits a similar modified form of the sensus divinitatis in his Reformed epistemology whereby all have the sense, only it does not work properly in some humans, due to sin's noetic effects.

    There is a lot going on here, but the above is one strand which I think I can deal with without grappling with any special reading (evolutionary naturalism).
    The author (Plantinga?) has grasped one relationship between the physical and another category, but has not noticed that there are other relationships available. I offer two examples.
    First, each piece in a chess set is a physical object which consists of one substance or another in a specific shape. We even say that the king is this piece - holding up or pointing to the physical object in question. But what makes it the king has no representation in the conceptual structures of physics. It is the king because the rules and conventions of chess make it so - it is the king in the context of a chess game. Physically speaking, it is just an object like any other.
    Second, - and perhaps closer to home - each number in a calculation has a physical - what shall I call it? - correlate. 1, 2, 3, Again, qua physical mark each number has a representation in the conceptual structure of physics. However, qua number, it does not. What makes it a number is the rules that we apply to it (better, that we follow in manipulating it) - in the context of a mathematical calculation or in the context of counting or measuring physical objects.
    When we use a machine to do a calculation, we have assigned various physical phenomena to a mathematical role, and arranged causal sequences to correspond to the mathematical operations we are interested in. What makes the physical events within the machine into a calculation cannot be recognized as mathematical calculations unless we have arranged that representation. It is not the result of any physical properties or events within the machine independently of the context in which we interpret them.

    Suppose the dog has learnt to read the station clock or at least to get up and start some preparatory tail-wagging when the clock says 5 - are you sure that they are incapable of that?Ludwig V
    What have clocks to do with rational thought? For 100,000 years of intelligent human development no clocks of any kind existed. Up until four hundred years ago, the entire population of North America was clock-free, and very possibly the healthier for it.
    All the world is not accessible to you, even while the observed and recorded behavior of (some) animals, is. What is not included in the observed and recorded behavior of animals, is that which is the cause of it, which we as humans consider rational thought.Mww
    Well, there's me in my place. That which is accessible to you regarding other humans is not accessible to me regarding other animals. Even if you have never seen that human in the flesh and even if I had close personal acquaintance with animals.

    Experiences can be hard to explain to someone who has not had that particular experience. Remember Spock in a Star Trek episode, where he died and Doc asked him what it was like to die? Spock asked him if he ever died, and incredulously Doc said "no". Then Spock said, if he did not have the experience he had nothing to reference.

    I rather be with people my own age, who have gone through my time in history, because they know what I am talking about. That is not the case when talking with younger people, who may be sure I am wrong because they have not had that experience. :lol: It is laughable when an organization has changed its policy and I object to the change, and the young person who has been on the job for maybe 6 months, tells me there was no change and things are as they always were.

    Amazingly, human beings can proceed and believe humans are intelligent and capable of communication when they are not working with the same facts and understandings of life. While bees and ants have almost perfect communication. I don't think anyone would say they are intelligent. They are not self-aware and reasoning how to build their homes or go about their chores or who the queen should be queen. We might say the ants and bees are more rational than humans because they don't carry false or incorrect stories about what is so.

    I think we could make a good argument that human beings are not rational. The chatter that goes on their heads may be totally incorrect but without critical thinking, they may be willing to kill for what they believe is so.

    Thank you for opening the discussion on human thinking.

    Ever been to the center of the Earth? Have any experience of it, whether direct, indirect, 1st, 2nd, 3rd…..hand? Ever going to? Think you got enough time to experience all those parts of the world that are accessible you?

    I don’t care about whatever place you’re in, only what you say while you’re there.

    Oh, we can be quite irrational in language, too. Just listen to a speech by.... never mind.
    Humans have an enormous brain, only a small part of which is required to run the vital physical systems and another small part for reflex actions and survival instincts. The rest is available for learning, memory, language, culture, skill acquisition, storytelling, convictions, wealth accumulation, altruism, invention, emotional complexity, deceit, social bonding, philosophy, ambition, superstition, delusion and madness. As well as reasoning and assessment.

    But all that is not rational thinking. Rational thinking requires critical thinking and we would have an extremely short lifespan if all our awake time was also our critical thinking time.

    Colloquially, “rational” has several meanings. It can describe a thinking process based on an evaluation of objective facts (rather than superstition or powerful emotions); a decision that maximizes personal benefit; or simply a decision that’s sensible. In this article, the first definition applies: Rational decisions are those grounded on solid statistics and objective facts, resulting in the same choices as would be computed by a logical robot. But they’re not necessarily the most sensible. https://qz.com/922924/humans-werent-designed-to-be-rational-and-we-are-better-thinkers-for-it

    Rational thinking requires a huge amount of energy and we would have very short life spans if all our waking hours we were thinking rationally. Also, it is fun to know forgetting is as important to making sense of life as learning is. One of the hardest parts of learning is often we must forget to have useful information in the present. You don't want to know your grocery list for every time you have gone shopping. You only want today's grocery list and if too much information is in our conscious thoughts it becomes useless.

    Completely rational thinking has draw backs and here is an explanation of that...same link

    “If you fine-tune on the past with an optimization model, and the future is not like the past, then that can be a big failure, as illustrated in the last financial crisis,” he explains. “In a world where you can calculate the risks, the rational way is to rely on statistics and probability theory. But in a world of uncertainty, not everything is known—the future may be different from the past—then statistics by itself cannot provide you with the best answer anymore.”

    Henry Brighton, a cognitive science and artificial intelligence professor at Tilburg University in the Netherlands, who’s also a researcher at the Max Planck Institute, adds that, in a real-world setting, most truly important decisions rely at least in part on subjective preferences.

    “The number of objective facts deserving of that term is extremely low and almost negligible in everyday life,” he says. “The whole idea of using logic to make decisions in the world is to me a fairly peculiar one, given that we live in a world of high uncertainty which is precisely the conditions in which logic is not the appropriate framework for thinking about decision-making.”

    Several Star Trek shows are about human judgment that is not based on rational thinking and I don't think Star Trek fans are in favor of AI ruling over us.
