• The Predicate of Existence
    Very interestingly, would this apply a lack of freewill?chiknsld

    If free will is possible (logically consistent) then it exists. But how is free will defined? Without definition there is nothing. If free will means that we can do what we want then we obviously have free will, at least to some extent. But even then, our actions would be completely determined by factors over which we have no control, in the sense that they would be determined by our wants and we cannot choose our wants. Or if we could choose our wants, we would need to want to choose the wants, so there would be a regress of wants that would either begin with a want that we wouldn't choose or it would be an infinite regress, which we wouldn't choose either because there would be no beginning to choose.
  • The Predicate of Existence
    What caused existence to be, and why?chiknsld

    I think this is equivalent to asking "What caused logical possibility (consistency) to be, and why?" Like, why is A identical to A (and not identical to that which is not A)? Logical possibility is a necessary fact. And some years ago I came to this big revelation: there is no difference between logical possibility and existence. Why? Simply because I don't see any difference between the two and I don't even know what that would mean.

    Claiming that there is no difference between logical possibility and existence may seem absurd because you may readily point to an object, for example a tree in front of your house, and say "It is surely possible (logically consistent) that that tree over there would not exist, and yet it is there - hence, logical possibility and existence are not the same." To which I would say: "Um, no. It is not possible for that tree not to be there, because it would be a logical contradiction if a tree that is there was not there." It may be logically possible for there to be another world which looks exactly like ours except for that tree, but that would be another world, not this one.

    So not only is existence necessary, but everything possible exists necessarily.

  • If Dualism is true, all science is wrong?
    It is really quite irrelevant that there is a quale representing a “feeling of what it is like”, if there is no aesthetic judgement made in relation to it.Mww

    Qualia have been posited as qualities of consciousness, as opposed to relations. They stand in relations and thus ground a structure of relations but qualia themselves are not relations and have no internal structure. They seem to fit the qualitative, unstructured character of basic elements of consciousness, for example the experience of red color, which is a homogenous, monadic redness. Qualia fit into a fundamental metaphysics of qualities and relations where both qualities and relations are seen as inseparable from each other: if there are qualities there must also be relations between them, and if there are relations there must also be non-relations (i.e. qualities) between which the relations hold. While relations can also hold between other relations, they must ultimately be grounded in non-relations, otherwise relations would be undefined.
  • If Dualism is true, all science is wrong?
    On a representationalist view, there is a separation of (subjective) experience from the (objective) world. The subjective experience has to be synthesized from the signals coming from the environment. Hence the binding problem.

    Whereas on a non-representationalist view, what we perceive just is the world (which we have attendant thoughts and feelings about). The signals coming from the environment enable us to perceive what is there.
    Andrew M

    But even in the non-representationalist view we don't perceive a tree (an external object) directly but only as "marks" left by incoming photons in our nervous system and these "marks" are a representation of the tree, not the tree itself, so I don't understand why such a view would be called non-representationalist.

    When an OCR machine recognizes an alphabet character or a self-driving vehicle recognizes a pedestrian crossing the street, does it do so via a representationalist method or a non-representationalist method?
  • If Dualism is true, all science is wrong?

    I mean programmed like learning machines. But initially the wouldbe organism has no goals (blind nature doesn't program any particular goal in it), it just exists and if it happens to have what it takes to survive, it will survive. If it doesn't have what it takes to survive, it will not survive. Those that are left will appear to have a "goal" of survival. But even those will decay over time. Some of them might happen to get the property to produce new copies of themselves and so they will continue to survive in their copies and will appear to have another goal: replication. As time passes they may change and get more properties and more goals, some of which may be subgoals to aid survival or replication, other goals may be irrelevant to survival or replication, and some goals may even be against survival or replication but if not too much they may not die out.

  • If Dualism is true, all science is wrong?
    In our modern age, the idea of a soul as a conscious entity that can incarnate in a physical body and survive the physical body's death faces this dilemma: How can the soul interact with the physical body without being detected by scientists? In other words, if the soul interacted with the body via a very weak force, it might elude the observation of scientists but its influence on the body would seem insignificant; if on the other hand the soul interacted with the body via a relatively strong force, this force should be detectable by scientists.

    How to resolve this dilemma? Well, there seems to be the possibility that the soul would interact significantly with the brain but it would elude detection because scientists would be unable to tell whether changes in brain activity that are measurable with contemporary brain scanning technology (fMRI, EEG) are or are not entirely caused by known particles or fields inside or outside the brain.

    Still, if the soul was constituted by unknown particles or fields, why would such particles or fields not be detected in particle accelerators where they can be measured much more accurately than with brain scanning devices? For some reason, the soul would interact strongly with known particles in the brain (where it would be undetectable because of the complex brain processes and the limited resolution of our brain scanners) but it would interact only weakly with known particles in accelerators (where it would be undetectable because of the weakness of the interaction).

    I don't know if this idea is viable but maybe the unknown particles that would constitute the soul normally interact only weakly with known particles (which makes them undetectable in accelerators) but their interaction with known particles in the brain is significantly amplified by resonance that can only occur between certain complex systems such as a soul and a brain (neural networks).

    According to theory of relativity, time is a kind of space. That seems to explain how time may exist within a larger, timeless reality. Time itself is just one of timeless mathematical objects (a space), so there is no "passage" of time just as there is no "passage" of space or of any other timeless mathematical object. The "passage" of time is therefore just a feeling, a property of certain complex parts of spacetime that we call "conscious".

    I can imagine how a cylinder looks like a square when seen from fare away but I can not imagine how a quantum wave looks like a particle by any manipulation of my mind.FalseIdentity

    A quantum wave doesn't look like a particle. In Bohm interpretation the wave and the particle are two different objects, but you're right that the Bohm interpretation is not popular because it requires faster-than-light signalling, which messes up the well-tested theory of relativity. The most popular interpretations of QM among physicists seem to be many-worlds and Copenhagen. According to Copenhagen, when the quantum wave interacts with a macroscopic (many-particle) object, the wave collapses into a particle, maybe somewhat like when a baloon bursts and only a small speck of it remains. According to many-worlds, when the quantum wave interacts with a macroscopic object, the wave splits into many non-interacting worlds, so that only a small part of it (a particle) remains in each world; in each world it looks as if the wave collapsed like the Copenhagen says. The collapse or splitting of the wave is caused by the barrage of particles from the macroscopic object the wave comes into contact with (a process called decoherence).

  • Logic is evil. Change my mind!


    Not everything that seems weird to you is logically contradictory. The law of non-contradiction states that "contradictory propositions cannot both be true in the same sense at the same time". (https://en.wikipedia.org/wiki/Law_of_noncontradiction) I have underlined the "in the same sense at the same time" part because it is critical for understanding what a contradiction is. When I say that an object looks like a circle from one perspective and like a square from another perspective, this is not a contradiction because there are two different senses in which the object looks (two different perspectives). The object may be a cylinder. (It is not a "square circle".)

    In quantum mechanics, a small object like an electron is a probability wave (cloud) extended in space when it has not interacted with a macroscopic object, and it is a "pinpoint" particle when it has interacted with a macroscopic object. Again, there is a difference in senses (and in times, but "times" may be subsumed under the meaning of "senses"), so no contradiction. Bohm interpretation of quantum mechanics says that an electron is both a particle and a wave at the same time, but even here there is not necessarily a contradiction because the electron can be seen as a collection of a particle and a wave, so the particle and the wave are not one object but two different objects, and their collection is a third object that we can call electron.

    If they are not nothingness or absence then they fail to convey the nothingness or absence that I mean by A = -A.James Riley

    But they cannot be nothingness or absence because nothingness or absence mean not-being. If you want to convey that nothingness is "covered" by somethings, the coherent way of doing it could be by pointing out that nothingness is "contained" in somethings as the "content" of empty sets, and not by identifying nothingness with somethings.

    To say that nothing is something simply because it is an idea or concept that must be categorized for reference/contrast to that which exists, is like referencing a book that contains both concepts (something and nothing) but which is still a thing (book).

    I'm talking about the book itself not being itself.
    James Riley

    The book is still itself and is not nothing, even when it contains references to nothing. Informally we use the word "nothing" not in the sense of exact nothingness but to express absence of objects that are important to us, for example you see an empty room and say there is "nothing" in it, although there is obviously space there (which is something that has mathematical properties) and teeming with air molecules and whatnot. And if the book happened to contain a reference to exact nothingness, I would interpret it as the "content" of an empty set.

    So this is a violation of the law of the excluded middle: the electron is there and there and somewhere in between all at the same time.FalseIdentity

    Not necessarily. There doesn't have to be anything contradictory about an object being in several places at the same time. For example, my desk is in several places at the same time: one leg here, another leg there... Where's the contradiction? An electron being in several places at the same time means that it is a spatially extended object (although not exactly in the same way as a desk), not a pinpoint object as we used to imagine (although it can change into a pinpoint object under certain circumstances, namely when it comes into contact with a macroscopic object, for example with a measurement instrument).
  • Logic is evil. Change my mind!
    As I stated earlier in this thread, I try to steer away from the word "things", singularly, or as a suffix. My reasoning is set forth in that post and I'll not repeat it here. However, the same analysis applies to the word "objects." All stands for All, whether object or non-object. Otherwise, it could not be All, now could it? It covers things and not things, or nothing, if you will. It covers presence and absence. It is and is not.James Riley

    By "object" I just mean something, or not-nothing. And every something has an identity: it is what it is, it is identical to itself. There is not anything more in addition to all somethings. Still, in a sense there is nothingness inside each empty set and between any two sets that don't overlap (their overlap is an empty set too). Empty sets are not nothing; they are somethings whose identity is that they are sets (collections/combinations) with no members (parts). So in a sense, somethings "cover" or "contain" nothingness or absence but they are not nothingness or absence; identifying something with nothing would be mistaking a set with its content (in the case of empty sets, they have no content).

    2. You asked me what I thought A = A means. I mistakenly answered your question assuming X, not A. And I answered as I thought logic would answer, not me. So let me clarify. For me, A means All. Thus, A = A means to me that A not only = A, but it also = -A. In other words, All is not only All but it must necessarily account for (=) the absence of itself. Otherwise, it could not be All.James Riley

    By A, I meant any object. So any object must be limited to what it is. But if A stands for all objects, what else is there in addition to all objects? Nothing. So not-A is nothing (no object) and it can't be identical to A because A is something (objects).

    Interpreting A = A as limiting a thing to what we say it is would make the thing's identity subjective to us and vulnerable to our misidentification or mischaracterization of it.

    My understanding of logic is that it is an elaboration of the principle of identity or non-contradiction: every object is what it is and is not what it is not. This must have been true even before the humans appeared on the scene, otherwise reality would not be what it is and what is true would not be true, which would be nonsense. Humans learn this universal logic and apply it to their daily life and later also to religion, philosophy and science. It can be used for both good and evil.

    So reality itself is logical, in the sense that it is what it is. And that's all that logic tells you: an object is what it is. But it doesn't tell you what the object is - that's a non-logical aspect of reality; however, this non-logical aspect of reality is inseparable from the logical aspect of reality.
  • What does hard determinism entail for ethics ?
    As previously mentioned, the general concepts of pleasure and the ethical don't have strengths, as they are general and not particular instances. The initial act of prioritizing pertains to the general concepts. That act is unmotivated, that is, free, and yet it is informed.Samuel Lacrampe

    Things that don't have strength cannot influence us; they are inert. We can only choose between them unintentionally or without caring about the choice. If general concepts don't have strengths, they cannot influence us - they have no attractiveness for us. We cannot even be conscious of them. However, we can be influenced by concrete examples or concrete symbols (for example heard or seen words) of general concepts, and we can also be conscious of these concrete things.

    Let's give an application of that idea. Suppose there existed a "happy pill": a pill that gives immense pleasure. The cost is that, as a result, you are effectively in a comma; you are no longer able to interact with the ones you love, build a family, make an impact in the world; etc. Would you take it?Samuel Lacrampe

    I don't have much expectation that such a pill exists and it also raises questions about how long the pill would work (shorter duration decreases total pleasure) and whether it is harmful physically, mentally or socially, including to my social relationships (all these harms decrease total pleasure). So if it resulted in a long-term blissful paralysis, it is safe to say that it would cause great harm to my relationships, which could decrease its attractiveness for me to such an extent that I would reject it.
  • What does hard determinism entail for ethics ?
    To be clear, this claim that "strength is not a factor" only applies to the initial act of prioritizing one end over the other. After that, strength is definitely a factor,Samuel Lacrampe

    But why would you prioritize one end over the other? Because one seems more attractive to you than the other. So strength of motives is a factor in any intentional choice. A motive can motivate you only through its strength (attractiveness). You may sacrifice great carnal pleasure but this sacrifice is more than compensated by satisfaction from fulfilling an ethical desire or need.
