    That they have spatial & temporal extension of some sort?Marchesk

    You’re in Schrodinger’s Cat territory, which is the graveyard of many a thread. However, I can produce one of my stock quotes on this exact point, from someone with unusual authority in this particular question, namely Werner Heisenberg, who said:

    ...the inherent difficulties of the materialist theory of the atom, which had become apparent even in the ancient discussions about smallest particles, have also appeared very clearly in the development of physics during the present (i.e. 20th) century.

    This difficulty relates to the question whether the smallest units are ordinary physical objects, whether they exist in the same way as stones or flowers. Here, the development of quantum theory some forty years ago has created a complete change in the situation. The mathematically formulated laws of quantum theory show clearly that our ordinary intuitive concepts cannot be unambiguously applied to the smallest particles. All the words or concepts we use to describe ordinary physical objects, such as position, velocity, color, size, and so on, become indefinite and problematic if we try to use then of elementary particles. I cannot enter here into the details of this problem, which has been discussed so frequently in recent years. But it is important to realize that, while the behavior of the smallest particles cannot be unambiguously described in ordinary language, the language of mathematics is still adequate for a clear-cut account of what is going on.

    During the coming years, the high-energy accelerators will bring to light many further interesting details about the behavior of elementary particles. But I am inclined to think that the answer just considered to the old philosophical problems will turn out to be final. If this is so, does this answer confirm the views of Democritus or Plato?

    I think that on this point modern physics has definitely decided for Plato. For the smallest units of matter are, in fact, not physical objects in the ordinary sense of the word; they are forms, structures or—in Plato's sense—Ideas, which can be unambiguously spoken of only in the language of mathematics.
    — Heisenberg, The Debate between Plato and Democritus

    There was also an article I mentioned earlier in this thread, which talks about the nature of the existence of sub-atomic ‘particles’ in terms of the Aristotelian idea of ‘potentia’, and which also mentions Heisenberg, namely, Quantum Mysteries Dissolve if Possibilities are Realities.

    We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to analysis, it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes.

    Well, we know that now.

    But I still reckon that the idea of determinism and of life being the 'accidental collocation of atoms' is the go-to philosophy of the proverbial man-in-the-street.

    I remember years ago, on breakfast radio, the presenter, who is a math and science geek of note, was interviewing Lawrence Krauss about, you know, life, the universe and everything. The conversation turned to dark matter/energy. 'It's a fact that science now thinks that only 4% of the total mass and energy are known to us, right?' 'Yeah, that's what seems to be the case.' 'So, that missing mass could be all around us, and we'd never know it was there?' 'Yeah, could be'.

    The conversation moved on. :-O

    If something doesn't have any effect on perception, then it makes no difference to us human beings whether it exists or not; there can be no evidence for it, so there's nothing to discuss (other than in terms of speculation). Certainly, one cannot make intellectual, moral or political policy proposals based on it.

    Husserl said that each moment of experienced time( time consciousness) was a tripartite structure of retention, Immediate presentation and protention. In order to experience any 'now' , we are also experiencing g the passing of the just prior now, in he form of retention, a kind of trace of memory. The now also has a protentional component, an anticipating or intending beyond itself into the future. If you think about it, this makes some sense. Awareness is situated as anticipatory, as being directed toward the future.Joshs

    I agree with this. So let's begin with this assumption, this premise, as an approach toward looking at the physical world. Notice first, that this description does not describe the physical world, it describes our experience, memory, presence, and anticipation.

    The fact of the matter is that experienced reality never repeats itself exactly, not our perceptions moment to moment or our conceptually accessible world. So we are already used to the idea, from our own experience of it, that the future is going to evade our attempts to precisely duplicate our present or past. Rather than making future reality, however you want to characterize
    it, nonexistent, it does the opposite. EX-istence moment to moment implies a certain aspect of non-predictability, of exceeding the past in some qualitative way. But that isnt normally a problem for us. For instance, our perceptual system is designed to optimize for regularities, patterns, consistencies in the flux of incoming sensation. So we don't normally notice the fact that our perceptual world is not self-identical moment to moment. It apppears that way to us because our perceptions abstract the regularities.
    Joshs

    In relation to the physical world then, you had suggested that each moment of the present could not be predicted in an absolute sense. This would indicate that there is no linear continuity of physical existence between past and future. The present provides a discontinuity to physical existence. My point was that if what we understand as "physical existence" is provided by our experience of past events, and there is no necessary continuity between past events, and future events, then we cannot validly extend "physical existence" into the future.

    So it is not my claim that the future is not part of reality, or that the future is "nonexistent" in any absolute sense. What is my claim is that if the future is part of reality, and existent, then we must allow that the non-physical is part of reality and existent. And I see no reason to exclude the future from reality. So rather than excluding the future as unreal, and non-existent, we allow, from our experience of anticipation, that the future is very real, and existent, just like we allow from our experience of memory, that the past is very real. But this necessitates that the non-physical is also very real.

    That is what the physical world is, a reality of constant flux, out of which we are able to extract and construct regularities.
    If we try to turn these regularities into determinisms, we may preserve a prectability at the cost of a meaningful understanding of a constantly developing world.
    Joshs

    The "constant flux" refers to our presence. Presence consists of the reality of a determined, physical past, and the reality of an undetermined, non-physical future. Since the past is real, according to memory, and the future is real according to anticipation, the question we must ask is whether the present is real. Is our experience of presence anything more than just anticipation and memory? If there is a real difference between past and future, as I have described with "physical" and "non-physical", then necessarily the present, as the division between these two, is real. Then, the constant flux which we experience at the present may also be said to be real. But if there is no such difference between past and future, if the past and future are equally "physical" for example, then the present itself is nothing real, and the constant flux, which is a feature of our presence is also not real.

    In ordinary parlance to say that there are. for example, multiple sheep is exactly the same as to say there are a number of sheep. I'm not claiming that an elaborated concept of number is inherent in nature (although if we are part of nature and such a concept is in us then in that restricted sense it is inherent) but that multiplicity (the fact that there are numbers of things) in nature which is inherent is the prior and necessary condition for any elaborated concepts of number.

    This doesn't follow, because the future, when it becomes present will be physical in just the same sense as the present is and the past was. It is better to say that the future is non-actual; it exists only as potential, and if nature is not deterministic; what it will be is not yet determined.

    No, that's clearly contradictory. The future is what is always ahead of us, just like the past is what is always behind us. To say that the future becomes present is contradictory therefore. What is the case is that events anticipated may become present, but the future does not become present. Likewise, we say that past events were present, and events occurring now will be past, but it would be contradictory to say that the past was present.

    To avoid this type of confusion, I tried to be clear in my post, to distinguish between time as we experience it, and the physical world. What I was trying to do is to establish a relationship between these two, time and the physical world, not to conflate these two, as you are doing.

    It is better to say that the future is non-actual; it exists only as potential, and if nature is not deterministic; what it will be is not yet determined.Janus

    So, with respect to this statement. We cannot say that the future is non-actual, because the future is just as real as the past. It is only by referring to physical existence, that we can make statements like you have here. So physical existence in the past is actual, and physical existence in the future is potential. But when we refer to time itself, both past and future are equally real. The difference between future and past which we can describe in terms of actual physical existence, and potential physical existence, is a substantial difference according to this description. Because of this substantial difference, the present is necessarily something real, as the separator, the boundary. As Joshs stated, we observe the present as constant flux. This flux is described as activity, so here we have another sense of "actual existence", activity, which is not the same as the "actual physical existence" which I have just described as proper to the past.

    The notion of subatomic particles as forms or ideas rather than things can be situated more accurately under Kantian categories than under Plato's eternal forms. But if this is true of subatomic particles, according to Kant it is true of all 'things'. They are all understood via propositions of language. No thing in itself appears to us because we understand reality through transcendental categories of space, time, etc. and the constructive activity of conceptualization.
    THis does t really have much bearing on the naturalistic formulations of current philosophers of mind, most of whom are neo-Kantians anyway.
    These thinkers, while acknowledging that physics is not a direct contact with language-free objects, see our scientific concepts in terms of a correspondence or mirroring of something out there we can't have direct contact with as objects.
    The interesting debate is between these neo-Kantians and philosophers( and psychologists) who dont see out concepts as mirrors of an external nature but transformative interactions with an evolving world.
    They dont see mathematics and science as offering us a privileged language of description of the world in relation to philosophy or other disciplines. Instead these are special types of pragmatic discourses that are used for practical engagement with the world. Their potential as evolutionary tools, as achieving progress in understanding, is not in their use of math but in their inventing of new dimensional frameworks within which to order and predict the world. In this endeavor they are no more capable than philosophy. In fact, it has been philosophy that has taken the lead historically in anticipating new sciences(Descartes, Leibniz and Newton), Hegel and Darwin, Nietzsche and Freud,
    Husserl and cognitive science).

    It's not at all contradictory to say that is what now future will become present, just as what is now present will become past.

    We cannot say that the future is non-actual, because the future is just as real as the past.Metaphysician Undercover

    The past is determined whereas the future is not. The past is non-actual in a different way than the future is. Actual can mean present and in this sense past is non-actual. But actual can also mean something like capable of acting, and in that sense the activity, or actuality, of the past is determinable in the present. We can also say the future is capable of acting, but its activity is not determinable, because in itself it is only a possibility, yet to be determined. The future acts only on beings who are capable of anticipating it; whether consciously or unconsciously.

    Sorry this reply took so long, but it’s a long reply.
    .
    I'm wondering how your model of if-then abstractions as a description of reality accounts for what it is that these abstractions are derived from. I don't mean an external world of material objects. I mean the moment to moment experiences that constitute all of our awarenesses, of changing perceptual features, of affective valenced dispositions and inclinations, of fragments of meanings, etc. Aren’t these building blocks of the abstract facts that populate your system in some sense more real than the concepts derived from them?
    .
    Yes. Experience first. It seems to me that it comes down to our experience (but that's the bias of an experiencing-being). Each of us is the center, the primary and essential component, of our world, our life-experience possibility-story and, secondarily, the possibility-world that is its setting.
    .
    I guess the main requirement of our experience is that it not be self-contradictory*, because a proposition can’t be true and false. For each of us, our own system of consistent inter-referring abstract if-then facts is subject to that fundamental requirement.
    .
    *But it isn’t obvious to me why that is. If there are infinitely many (consistent) possibility-stories, aren’t there also infinitely-many (inconsistent)impossibility-stories too? It seems to suggest that maybe logic is metaphysically-fundamental after-all.
    .
    We and our experience are what give meaning and relevance to the logical facts. …and that experience-story is more fundamental, as I mentioned above. …for us anyway, because, as animals, purposely-responsive devices, response to our environment is what we are.
    .
    Nisargadatta said that we don’t create the word, but we make it relevant. But, when “relevant” means relevant to us, and we purposefully-responsive devices are billed as the bestowers of relevance and real-ness, doesn’t that sound circular, and give un-due self-importance to us purposely-responsive devices? That’s what I call an “animal-chauvinistic”view.
    .
    And then there’s the fact that the abstract facts constituting our life-experience possibility-story aren’t really different from all the other ones. (…just as our bodies’ atoms aren’t different from those of our physical environment. We, our bodies, are part of the physical world, and likewise, in the same way, our life-experience possibility stories are part of the logical world.)
    .
    …and the fact that our life-experience story seems to have to be logically-consistent, not self-contradicting—suggesting that abstract logic governs, has authority over, personal experience.
    .
    And there couldn’t have not been abstract logical facts, because an abstract if-then fact, or a system of inter-referring abstract if-then facts, doesn’t need any outside justification, context, continuum, medium, or reality or existence in an outside context. It need only be self-consistent, within its own context.
    .
    So there couldn’t not be abstract facts, because each of those facts, and each system of inter-referring abstract facts, is independent of outside context, and needn’t be real or existent in any context other than its own. …and doesn’t need a medium or continuum in which to exist or be. …doesn’t need some sort of global permission that could be negated by a global fact that there are no facts.
    .
    Someone pointed out that if there were no facts, then the fact that there are no facts would be a fact.
    .
    But someone else pointed out that there could obtain a fact that there are no facts other than that one fact that there are no other facts.
    .
    …but such a fact would be a special brute-fact, in need of explanation, but not having it (how could it, if there are no other facts?).
    .
    Besides, for the reasons that I mentioned above, an abstract fact, or a system of inter-referring abstract facts, is completely isolated and independent of anything outside it, and doesn’t need a global permission that could be denied by a global fact like the one suggested in the 2 paragraphs before this one.
    .
    Those are reasons why I say that absolute Anti-Realism is out of the question.
    .
    For all these reasons, I feel that the Anti-Realist metaphysics that I propose can’t really be complete, even metaphysically. But I propose it anyway, because it’s still locally valid, as a subset of what metaphysically is.
    .
    …because, as I was saying before, a system of inter-referring abstract if-thens about hypotheticals that is my life-experience possibility-story is just as valid as any other abstract facts. And, because, from the special point of view of purposefully-responsive devices, our own experience is central, then our experience possibility-story is primary. …locally from out point of view, as purposefully-responsive devices.
    .
    So Anti-Realism makes sense locally, in the world of purposefully-responsive devices, but can’t be taken to obtain generally and objectively.
    .
    One other thing that I’ve got to say: One instance where I disagree with what Tegmark has said, is where he said that his metaphysics explains reality. No, a metaphysics can only explain metaphysical reality (where “metaphysical” means “describable and discussable”).
    .
    I don’t think any metaphysics can describe or explain Reality, and I don’t think Reality can be discussed, described, or explained.
    .
    I guess I'm wondering how your world changes and evolves. Is it through trying on for size new ways of talking about the world?
    .
    Isn’t that what philosophy is? Metaphysics is my main philosophical interest, though I don’t think it or its subject is everything.
    .

    Think about what you're saying when, on the one hand, you want to use the notion of nature to secure our propositions to something foundational ( yes, there IS a real world that our concepts are about, we want to insist). On the other you have to acknowledge that when we talk about this real world we find that we use terms in different ways in different contexts. You certainly could continue to insist that, once we get the tricky problem of clarifying our language out of the way, then we can finally get down to securing some concept like 'number' to some aspect of that real world. But what would happen if instead, you toyed with the notion that its language all the way down. That is to say, that the trouble of coordinating what we mean with what exists 'out there' comes from the fact that 'our there' is already fundamentally entangled with our engagement with it before it is ever possible to tease out a clear subject and world. If interaction and embeddedness are not something that is added to an already constituted subject and already constituted world, but the pre-condition for understanding, then it becomes nonsensical to talk about a world beyond or prior to our changing ways of talking about it.

    Although you're trying hard not to, I think you're putting the cart before the horse in placing abstract logic before the world. What I mean is, what you see as an irreducible precondition for any reality is, without your realizing it, already too full , harboring all kinds of presuppositions that are derivative rather than fundamental.
    Your logic relies on a notion of object as already constituted. I don't mean here physical or material object. I mean a conceptual object that persists in itself , that is self-identical in its meaning and sense, and then is pared with other such concepts. That's a traditional notion of logic that goes back to Aristotle. But there are recent accounts of logic that rid it of its too-full hidden suppositions.
    The basic idea is that what we experience moment to moment is not objects in the world, and it's not yet objects of thought. It's qualitative variations of meaning. The psychologist George Kelly defines our perceiving of the world in terms of constructs. A construct is simply a way in which two things(meanings) are alike and differ from a third. To be awake and experiencing the world is to be always construing. And to be construing is always to be construing something new, and slightly different from what came before. Piaget had a similar notion. He said that to experience something is to assimilate it into one's system of understanding. But at the same time it is to accommodate ones system of understanding to the unique aspects of what it is that one is assimilating. So, assimilation always implies accommodation.
    These are holistic accounts of experience. They also see the role and person as always in motion, and knowledge as anticipatory. They posit a knowledge system that encounters and construes the world always as a whole. They also assume that one can never encounter an isolatable element of ones psyche or world that isnt also a change in the system as a whole.
    Your notion of abstract if-then logic is a derived concept that is built out of a more primary activity of a recursive self-organizing system that is at every moment accommodating and transforming itself as it assimilates ever more new experience. Your logic doesn't realize that its static reifications are masking as much more
    mobile, dynamic and self-transformative process underlying it.

    Yes, a purely subjective experiential metaphysics would be neater, and, and as you said, i wanted that, and propose it as a our local metaphysical subset. But, as a whole metaphysics, it seems to run into problems--as I was discussing--and I couldn't justify it.

    That would be better, because I didn't want to believe that impersonal abstract logical facts are metaphysically fundamental.

    But then how do you explain the fact that our experience seemingly must always be logically self-consistent, never self-contradictory? Doesn't that suggest that logic is really in charge? ...that underlying logical rules govern our experience?

    They did emerge from a living world context, but when we engage with that world in an attempt to understand it , we are participating in the further evolution of that world rather than representing it. There are better and worse ways of doing this, that is, more or less adaptive constructions, but they don't amount to a View from Nowhere onto a pre-existing substrate. The paychologist George Kelly said the question isn't whether reality exists but what we can make of it.
    So I think the universe is an infinite development that we are participants in via our inquiries into its ( and our) nature. And I think that our successive attempts to understand it result in ways of engagement(for knowledge is an activity)that allow us to see the world in terms of regulaties and consistencies that are more and more integral and at the same time more differentiated. It's a very different notion than Newton's static clockwork universe composed of arbitrarily assigned parts in relationship.

    It's true that
    To me it's not a question of logical consistency in the formal sense, but of self-consistency, of the relative inferential compatibility of new experience with our system of understanding.
    A new event that appears inconsistent with our way of making sense of things will be handled in a number of ways. We can find a way to modify our previous understanding such as to make the challenging event consistent with our values. Or we can try and force the abberant meaning to comply with what we think it should mean. This usually doesn't end well. Or we can be left in a situation of crisis.
    When we encounter experience that is wholy outside our ability to make sense of it, to accomdate our system of understanding to make room for it, we simply are unable to assimilate it. Our negative emotions respresent these sorts of transitional phases in our experience, when our world threatens to become chaotic and incoherent. Some psychologies argue that we do incorporate conflicting ideas and then cope with this by hiding from ourselves the internal conflict(cognitive dissonance, Freudian repression).

    Maybe at this point we should ask what we want the term 'real' to do for us. And I suppose also the concept 'physical'. Do either of these notions become become disturbed if I bring into the discussion the idea that memory is itself a reconstruction, that there is no such thing as veridical memory, and therefore we do t have access to a trailing order of pasts that we can line up and study?
    By this way of thinking our past is actually in front of us in a way not unlike the present. Each past that we recollect is in a sense a fresh past, and points ahead of us. Recall is always for some future-oriented purpose of ours, so it is anticipatory.
    If you buy into this , I think the lesson it teaches is that notions like physical and real can still be seen as providing constraints on the free play of our conceptualizations( there is SOMETHING that we are trying to adapt our ideas to, and reference to this something can tell us if we are succeeding or failing). But
    if memory itself isn't just a veridical
    internal carrying of external objects via symbolization, but an inseparable component of a relational complex of the experience of the present, an experience that is at every moment disturbing our sense of past as well as present, then we may want to reimagine physical as more radically relational than traditionally assumed.

    Obviously we can only represent the world as it is presented to our senses. Bur if we believe language has emerged and evolved in the context of a living world then it would seem to be reasonable to expect that languages (including mathematics) as natural products, should reflect the structures and characteristics of that living world.

    If not then philosophy and discussion and any intellectual activity that purports to be of more than a merely practical nature would seem to be empty and pointless.

    In my view, "numbers" are abstract concepts that exist in the mind. Ontologically, they exist as particular mental abstracts in the form of brain processes. That means that "numbers" are dependent on minds; they are not independent of minds. If that were so, then that would obviously mean they exist extra-mentally.numberjohnny5

    This is obviously a very complex issue, but one response is to equate numbers with brain processes is a form of category mistake. Obviously, one needs a brain - and presumably a hominid brain! - to recognise numbers and perform arithmetical operations. But the same operations can be outsourced to a variety of different devices, other than brains. And in studying brains themselves, there are major obstacles in understanding the relationship of neural events and such elements of rational thought as number, logic, language, syntax, and so on.

    The Western rationalist tradition would say something like, numbers exist independently of any particular mind, but they are only perceptible by an intelligence capable of counting. In that way they're dependent on mind in one sense - in the sense of only being perceptible by a mind - but independent of it, in the sense of being the same for anyone who can count.

    So saying that 'numbers are dependent on the brain' (which is actually what you have said, not 'mind') doesn't really say anything. It just safely puts the whole issue into the category of 'things we'll figure out when we understand better how the brain works'.
