  • Reductionism and the Hierarchy of Scale
    And so the irony is that complexity is mechanical - but the causal action reaches down from above rather than works its way up from below.apokrisis

    Sure, in a laboratory we can make things, but nature doesn't think things out beforehand. But I doubt that either proposed upwards or downwards direction of natural complex development is logically possible or practicable. A lot of complexity just happens because of known or unknowable circumstances. Remove an enzyme and the organism dies and becomes source material for something else.

    But those [global] rules can't be the result of an evolutionary process - they must pre-exist it. Biological evolution at least assumes the existence of species of some kind for any kind of natural selection to operate on, because species uniquely possess the attribute of seeking to continue surviving.Wayfarer

    Evolution can be gradual or punctuated. The sudden bursts in emergence are the consequence of radical changes in the environment, such as fires, floods, volcanic explosions, poisons that create a nutrient rich environment lacking in dominant life forms. The environment is a third, more powerful force than any of the competing species. After environmental catastrophes new factors open possibilities for life. The rules are post hoc.

  • The start of everything
    The universe is about 70% dark energy. Dark energy is timeless. Another 25% is dark 'matter' that could also be timeless. The remaining 5% is plasma, like the stars, then there is scattered galactic dusting of minute amounts of what we call ordinary matter.

    So the universe started as concentrated pure energy and will end as ultra-thinned out pure energy. Sounds pretty boring, doesn't it?

  • How is truth possible?
    All this talk about "objective truth" is silly. Objectivity and subjectivity are properties that pertain to a mind. None of the literature on the theories of truth (pragmaticism, coherentism, correspondence, semantic, et. cetera) ever seems to actually investigate this isolated pop-culture idea about "objective vs subjective" truth.Kuro

    Silly is ad hominem name calling and not an argument. It only suggests that you lack familiarity with the subject, therefore you intend to tackle the opponent instead of the claim.

    Objective truth is a golden dogma and you can stick to it as you will. No problem. But others are at liberty to question the comfortable surroundings of strict and limiting non-contradiction with excluded middle. They will find other possibilities. By 'literature' you just mean standard dogmatic literature taught to undergraduates. It's OK, but there is much more to logic, and truth is only a value of a logical calculation in whichever logic one might choose.

  • Is materialism unscientific?
    My contention is that some kind of dualism is more scientific than materialismlorenzo sleakes
    I'm confused. Wouldn't that dualism be denied by any science that you can name?

    In which case consciousness would be left either a monist instrumental observational object of physiology, or an indirect suppositional construct of psychology, a perhaps an ungrounded model of philosophy, or just a plain real subjective personal insight, subject to sensation and perception, devoid of label?

    if consciousness is merely a by-product of physical processes then it cannot ever have any independent effect back to the physical world and therefore it cannot be detected or measured in any way.lorenzo sleakes
    This is an interesting thing to say.

    We know that the mind is indirectly affected by physical events as sensations and can indirectly cause movement and actions. But I don't know how that works for consciousness. If you say that consciousness is the reflective inner working of the mind, then I'd have to agree.

    Imagine if every time I clap my hands together I claim to have created a new ghost particle that can never be detected. Such a view would be dismissed as meaningless and unscientific. But the view that physical processes generate consciousness but consciousness has no independent effect back on physical processes is the same.
    No theory of a purely epiphenomenal mind can ever be tested. An invisible object which has no causal efficacy disappears into pure speculation.
    On the other hand if I clap my hands and create a particle called a poltergeist that I claim has some effect on the world then that claim can be tested, falsified and verified. At least it a scientific claim. We are discussing consciousness so it must have some ability to speak for itself.
    lorenzo sleakes

    I love thought experiments to simplify and clarify ideas and I also use them as often as I can. Are you here still talking about consciousness itself or about a broader interactive transcendent mind?

    Incidentally,
    Imagine if every time I clap my hands together I claim to have created a new ghost particlelorenzo sleakes
    Clapping is a physical act of slapping two material objects together in such a way that physical waves are produced in the air. Some instruments, like microphones, will detect the air waves. When a person or animal is present this is heard as a sudden loud sound.
    But clapping can also be produced by just one object or physical event, such as lightning, or a plane breaking the sound barrier, or a whip, or a wet towel.
    Never mind my musings. Obviously, when a tree falls in the forest it produces shock waves in the air and the ground, but sound must be heard.

    Take The Manhattan Project for example.

    So-called historical reasoning is a fallacy, quite typical of Marxist-Leninist thought. It takes history to be an objective criterion for political judgment.

    But history is different for each culture or political entity as is written in their language in their history books. Usually it fixes the world at the glorious height of a culture's power. Spanish and English history books will conveniently differ on issues of past national conflicts. Canadian and US history is different.

  • Immaterialism
    which, in fact, we do not need in order to survive and thrive in the world, so why does that matter?180 Proof

    To survive we only need enough partial knowledge to guess right about the next step, if we are wrong we pay the price. To do philosophy, it matters. We can only see physical projections from material objects that happen to land on the retina. Therefore direct realism cannot be more than a useful simplified model that roughly imagines our naive conceptions of the world.But indirect realism introduces physiological and psychological mechanisms that we can't explain. Therefore, direct realism.
  • Immaterialism
    Whereas materialists of all stripes believe that the objects of perception have intrinsic reality - the kind of reality that persists independently of any perception, sensation or judgement. — Wayfarer
    Patently false. Again. :sweat:
    180 Proof

    In An Enquiry Concerning Human Understanding (1748), Hume considers the common-sense view that we directly perceive material objects, such as a table. This sort of naïve realism is, Hume says,
    destroyed by the slightest philosophy, which teaches us, that nothing can ever be present to the mind but an image or perception, and that the senses are the only inlets, through which these images are conveyed. (Enquiry, XII.I.9)
    He then argues:
    The table, which we see, seems to diminish, as we move farther from it: But the real table, which exists independent of us, suffers no alteration: It was, therefore, nothing but its image, which was present to the mind.
    Gary Hatfield (upenn) for SEP

    Being limited by having only eyeballs to see the material world, such as it may be independently of our existence, says nothing whatsoever about the reality or lack of reality of that world. But it does show that we cannot possibly have direct irrefutable knowledge of that world. There are many alternative ways to prove this point, especially through quantum physics or any other science for that matter. Perhaps that may be what science does the best.

    This is the first bang, followed by the hot bang. What's wrong with it? Where it says stars are 20 billion years old? Do you have a link?Raymond

    You would have to read a critical but fair history of modern astronomy to get a picture of how the current theories evolved against the background of slowly accumulating observational results. Back then it was war between powerful and prestigious mathematical theorists hanging on to Einstein's coat tails and young unknown astronomers whose painstaking observations were put to doubt by the lack of agreement with grandiose theoretical speculations. Lerner's book even if obsoleted by later results makes for an interesting read.

    As for the early scramble for the oldest stars, I'm afraid I've misplaced my notes from the 80's and arXiv.org doesn't go back that far in astronomy. But this article on Methuselah gives a flavor on a smaller scale.
  • Origin/Theory of the Universe by Russian Cosmologist?
    Considering the "big bang" theory (which I do not subscribe to) - did time exist before the singularity expanded and did the space that it expanded into exist - or is that space created as the universe expands? If we believe that the universe is expanding then our reference point for time would be measured from the point of its "creation" until its current state of expansion, or at any referential points during that expansion, and therefore can only go forward (expansion). When we see the light from a distant star we are viewing the image of something from the past - from back in time - if we could get a close-up view of that image we would be viewing history of events that occurred then - but that has already passed - all we are seeing is an image. Could I now interject myself into that image and change some event, i.e. time travel? All I can do is see the image - I am not able to participate in it.Mason

    You're not alone! The Big Bang was quickly embraced from the beginning because it gave a scientific and at the same time a theologically satisfying explanation for the origin of the universe. Yet to many enthusiasts it felt like a stretch of imagination. This was further stoked by the even more fantastic second bang or just a smooth inflation.

    When astronomical observations started to come in, the numbers just did not add up. The stars proved more than twice the theoretical age of the universe. Oops. This gave rise to a wide spread amateur movement that The Big Bang Never Happened. After years of refinement ("refinement"?) the age of the universe was raised from 8 billion years and the stars were squeezed down from up to 20 billion years to more or less 13.8 billion years. :party:
  • Origin/Theory of the Universe by Russian Cosmologist?
    The torus model looks a lot like what sprang up in my mind. But it has its difficulties (of course I say that!).Raymond

    Sounds to me, by torus you mean a geometric model. Would you consider the magnetic fields of planets, stars as torus? Black holes like the ones in the center of many galaxies appear to be torus like from a great distance but they are motivated into that appearance by equatorial accretion disks due to gravity and polar bidirectional outward streams of charged particles in a polarized field.
  • If Dualism is true, all science is wrong?
    Charge is attached to a particle... They can't be pulled apart. — Raymond
    Um, right. That's because its not "attached to" it in a physical sense (again with the physical metaphor), charge is a property of a particle, and so its not meaningful to talk about "pulling it apart" any more than it would to talk of "pulling apart" the redness of an apple from the apple.

    And in any case, charge is a physical property of a physical object- no mystery there. The problem is the proposal that the mental "resides in" or "is attached to" the physical in the way that a physical property like charge does with a physical object, without itself being physical. In other words, the interaction problem, dualism's harder problem of consciousness.
    Seppo

    Interesting thoughts. I don't know if the analogy of apples to physical particles helps here. Apples as objects can be grounded in the certainty of common perception, if we so agree. But physical particles are only categorized by their properties and do not have any material or observable substance. The lack of identity of physical particles should also be of very serious philosophical concern.
