• What is the difference between actual infinity and potential infinity?
    It is not necessary to adopt platonism to accept that there are infinite sets. One may regard infinite sets as abstract mathematically objects, while one does not claim that abstract mathematical objects exist independently of consciousness of them.GrandMinnow

    There is a metaphysical problem with claiming that there are objects which do not exist independently of consciousness, and that is that these objects are imaginary. And imaginary objects are subjective, property of individual subjects. Such objects could be false, contradictory, or a logical impossibility. So if mathematical objects have this type of existence, each one needs to be justified, or else anyone could make up any imaginary thing, asserting that it exists as a mathematical object.

    That is the problem with the infinite set. It is self-contradictory, an impossibility, which someone has asserted as an existing object, and other people have blindly accepted it because it is useful, without requesting justification. When we request justification, we see that "infinite set" is contradictory, as are most mathematical objects. And many which are not contradictory are irrational , like the principles of geometry.

    Here's an example as to how mathematical objects are self-contradictory. Take the number 2. As an object, it is a simple unity. However, it is necessarily two distinct unities, as that's what 2 signifies, two distinct objects. So either 2 signifies two distinct things, or it signifies one unity, a mathematical object. It cannot signify both or else 2 would be 1, and that's contradictory. And so we cannot conceive of "mathematical objects" as objects, without loosing the meaning of the symbol. There is an inherent contradiction in asserting that a symbol like 2 signifies an object, because the unifying agent which makes 2 into one object has not been identified, therefore that two are one object has not been justified, and there really is no such object.

  • Donald Trump (All General Trump Conversations Here)
    Why does Trump flirt with Putin and Kim, but he harasses Iran? Real question.frank

    Trump is, in his own eyes "the greatest deal maker ever". His MO as president is to nullify or cancel as many deals which were made before him as possible, asserting that they are terrible deals, and then he sets to renegotiating them with the tactics of a bully. He has cancelled the "Iran deal", calling it, "the worst deal ever" (which of course is what he called NAFTA, and probably many other deals he's cancelled like TPP). Now he's in the bullying stage, which is his route to negotiating a new deal. In the case of Putin and Kim, there's been no cancelled deal to renegotiate and he's buttering them up, probably hoping to get something from them (unless the rumours are true, that Putin already has something on him, then it's a different story).

    The concept “flow” is a condition of the concept “river”, but it is not a necessary condition, for a river that does not flow, i.e., tidal access rivers, is still a river.Mww

    This is nonsense, a tidal river still flows according to the direction of the tide. You've just rejected the generally accepted definition of "river", for personal reasons, to say that "flow" is not a necessary condition of a river. Anyway, it's not relevant to the discussion. Either you accept the analogy or you do not, and obviously you do not.

    The concept “free will” is a misnomer, because a free will that is not free in its volitional determinations cannot be a “free will”, but nonetheless a will.Mww

    I can't see your point. You seem to be suggesting that there is such a thing as a will which is not free, such that "free" is not a necessary condition of willing. How could that be, without accepting determinism. Care to explain, or are you just arguing determinism?

    Freedom is an indirect condition of the will, insofar as it is a necessary condition for autonomy, which in its turn is the necessary condition for the will to operate in conformity to its prerogatives. Forgive me; I took liberties with the theoretical philosophy of morals by not specifying the distinction between conditions and necessary conditions.Mww

    If freedom is a condition of the will, as explained here, wouldn't this contradict your prior statement, where you talk about a "free will that is not free in its volitional determinations"? Isn't this contradictory in the first place, to refer to a free will which is not free?

    I gave no indication that free will is displaced; I specifically itemized free as being separated from will.Mww

    OK, I do not mind separating "free" from "will", but then we must dispose of the idea that freedom is a necessary condition of will. If "free" is separate from and not a necessary condition of "will", then we have a will which may or may not be free. But if freedom is a necessary condition for will, then the will cannot be anything other than free. Which are you proposing? You seem to be talking both, which is contradiction.
  • Topic title

    If "freedom is the condition the will takes place under", then why is "free will" a misnomer? For example, lets say that "flow" is the condition a river takes place under. Why would it be a misnomer to talk about a flowing river?

    That being the case, it is more apt to say, “freedom is the condition the will takes place under”, which still isn’t quite right, but is close enough to work with, and incorporates the added bonus of showing how and why free and freedom both are necessarily separated/displaced from will. Logically separated because free will is always susceptible to self-contradiction, and temporally displaced because freedom is always antecedent to the will for which it is the condition.Mww

    Of course "free" is logically separable from "will", the former is the predicate and the latter the subject. So "free" may be predicated of subjects other than will. Because of this, we can see that there were free things prior to there being a free will, and therefore conclude that freedom is antecedent to the will. But this does not mean that free will is temporally displaced, nor is this conclusion produced by any self-contradiction. The claim that free will is susceptible to self-contradiction represents a misunderstanding of free will.

  • Why time as a fourth dimension should've been obvious


    The problem here is that the charting technique puts time as distinct from all three dimensions of space. So if dimensionality is defined by spatial existence time would be better represented as non-dimensional, or the 0th dimension.
  • Topic title
    The will existing as an autonomous casual means in no way requires it to be separate from time itself. It acts in time, is constrained by it, and to say it is temporally displaced is nonsensical.Pathogen

    This concept of free will requires a particular understanding of the nature of time and change. We see that time passes, and as time passes, time which was to the future of us becomes to the past of us.

    Now, we understand a continuity of existence, which is at the base of determinism. What has existed in the past will continue to exist onward into the future, unless there is a force which acts to cause change. This is expressed by Newton's first law, the law of inertia. However, we also can conclude that anything, and/or everything, including Newton's law, could possibly change at any moment of the passing time. This indicates that Newton's first law, which is the basis of causal determinism, is not itself a necessity.

    So we have the brute fact that the continuity of existence, expressed by Newton's first law, which is fundamental to determinism, has no support as a universal law. This is sufficient to support the reality of the observations which produce this statement:
    4.) Non-deterministic factors do exist in the physical universe.Pathogen

    Furthermore, we observe that these non-deterministic factors, things which are not subject to Newton's first law, are very active within the internal parts of living beings, and this supports the thesis of free will.
  • Determinism vs. Predictability
    No it doesn't. It requires a definition of determinism that implies prediction-making.Harry Hindu

    Right, the faulty definition of "deterministic", which you added is the premise required. It's a false premise though because it's not an acceptable definition of "deterministic".

    Predictions can only be made if occurrences that we observe are consistently determined by prior causes.Harry Hindu

    This is not true though, as I explained, a prediction could be made randomly and be correct by chance. Or, a prediction could be made using many other strategies, some of which I described, without the need for determinism. That the actions of a human being may sometimes be correctly predicted does not prove determinism, nor disprove free will, which would be the case if prediction could only be made when actions are predetermined.

    I think you are assuming "prediction" which has absolute infallibility, no chance of failure. This might require a deterministic system, but human prediction is unable to obtain such perfection. So, determinism is not required for a correct prediction.
  • Metaphysics - what is it?
    Yes, agreed, the discovery of new knowledge is mostly carried out with other, non-knowledge, tools/mental faculties.alcontali

    Good, but you're still not making the distinction which I asked you to make, between the thing, the tool, (knowledge in this case), and the activity which uses the thing. A tool is not the same as the activity which uses the tool. Knowledge is not the same as the mental activity which uses knowledge. If you make this distinction, then the same thing, an axiom for example, may be considered to be knowledge when it is used as a tool, put to work toward some goals, or it may be consider to be not-knowledge, not a tool, when it is considered to be arbitrary, and used as a toy in play like you described. The same thing is apprehended in a different way, depending on the activity which is using it.

    Likewise, if we take one specific type of activity, using knowledge as a tool toward a goal for example, we could potentially use many different tools toward reaching the same goal. Each tool (axiom, or piece of knowledge) selected to be used would be useful, but some would be better than others, specifically the tools designed for that particular type of task. And, no matter how good the tool appears to be, we ought to respect the fact that a metaphysician might find a better tool. However, more likely than not, this would involve changing the task (the activity). An activity is a means to an end, and analysis of the end might determine that the end itself is slightly misguided, or that the activity is not the most efficient way of reaching that end, so a change to the activity would be required, also requiring a change to the tool.

    Ha, but if we could "know" the nitty-gritty of these other, non-knowledge mental tools, then they are actually knowledge, and that would be contradictory. Therefore, I am opposed to any strategy that consists in trying to systematize these other mental tools, because in order to do that, we would need to thoroughly "know" them, which is is not possible, because they are not knowledge.alcontali

    I see that, but I wasn't talking about tools (knowledge) at that point, I was talking about the mental activity which uses the tools. So let's say that some mental activity employs "strategy", that's a word you've introduced. Strategy is a tool which is often comprised to a large degree, of intuition. So we cannot say that all strategy is knowledge. Strategy is a tool which is applicable toward bringing about a desired end. It dictates the way we act, in the sense that it is used to determine the way that the mental activity uses the tools, knowledge, and how the tools are chosen. So strategy is more closely aligned to the end (the goal) than it is to the activity (the means to the end), because it is used to determine the activity.

    Notice, I am not trying to "systemize" these mental tools, only to understand them. They are already systemized by the mental activity which uses them, and that's what makes them understandable, they are systemized. Therefore you've made an important error in the passage above. You have stated that it is not possible to know these tools because they are not knowledge. But there is an activity which brings knowledge into existence, so just because something is not knowledge doesn't mean that it is impossible to know it. A particular strategy for example may begin as not-knowledge (being based in intuition), but after being tried and tested it becomes knowledge. What this indicates is that there are mental activities which are not understood, because the tools employed are not knowledge, but these tools are not unknowable, our knowledge just has not progressed to the extent of knowing them.
  • Metaphysics - what is it?
    am heavily "epistemized" and deeply invested in the idea of the existence of various knowledge-justification methods.alcontali

    What do you mean by "deeply invested"?

    Still, I completely acknowledge that non-knowledge mental faculties are key, not just for the discovery of new knowledge, but in general. But then again, systematization means converting things into knowledge. If it is not knowledge, but rather intuition, this is guaranteed to be a failing strategy.alcontali

    Again, I think I need to stress the difference between knowledge, and mental activity. Do you agree that mental activity is not knowledge, but it uses knowledge? Furthermore, there must be mental activity which does not even use knowledge, as this would be required to account for the coming into existence of knowledge, unless you place knowledge as prior to mental activity (but this could only be intuition, which you deny as knowledge).

    So we must respect the fact that if we exclude intuition as knowledge, then we necessarily have mental activity which does not use knowledge, but can itself bring knowledge into existence. The strategy by which this mental activity proceeds cannot be "guaranteed to be a failing strategy", because it is responsible for the existence of knowledge. Therefore, the mental process which proceeds without the use of knowledge ought not be denigrated as a guaranteed failure.

    In the end, this kind of research rather amounts to playing with "cool toys". But then again, it is not possible to know what people will find unless they actually try. Furthermore, this type of research nicely emphasizes the true nature of axioms as fundamentally arbitrary starting points.alcontali

    I do not believe that this does show that axioms are arbitrary. This is because there is a difference between playing with toys, and working with tools. Playing with toys is random and arbitrary, but working with tools is purpose driven. Axioms are tools, they are not toys.

    Suppose we create an analogy in this way. Knowledge is a tool, and the thinking mind uses knowledge in its purposes driven activities as a tool. But the mind engages in other activities as well, more like playing with toys. The "toys" here are not knowledge, but in a way they are still tools, because the playing is in some ways purpose driven and it's just the case that toys are used by the mind instead of knowledge. The toys are the arbitrary axioms which you refer to, axioms which are not adopted for the purpose of doing any particular sort of work, which would make them tools. But they are used for the purpose curiosity and wonder, for play, like an artist playing with different colours, or a composer playing with different notes. So new axioms are discovered through this activity of creative playfulness, which because it is not putting tools to work it is not an act of using knowledge in thinking, it's more like thinking for the purpose of finding interesting things, playing. .
  • Determinism vs. Predictability
    If you predicted that it would break down, and it eventually does, then that is deterministic.Harry Hindu

    That's not true. When you predict that something will happen, and it does, this does not mean that the thing is deterministic. This conclusion would require a further premise which states that something can only be predicted if it's deterministic.

    Deterministic means that the outcome of some system is capable of being predicted by some mind. It follows some logical pattern. It is logical.Harry Hindu

    Neither is this true. Minds can predict things which are not deterministic by many different means, like chance, by some system of statistics and probabilities, or through vagueness in terms . I can predict the outcome of a coin toss. If I am right, I've successfully made the prediction. I can also predict that if I flip the coin 100 times half will be heads and half tails. If the score is 51 to 49 I can employ vagueness to claim that it's close enough to count as half and half, therefore my prediction was correct. For a prediction to be correct, it is not required that the thing predicted is deterministic, nor that the thing follows any logical pattern, it only requires a successful strategy by the predictor.
  • Metaphysics - what is it?
    Well, the link with classical, Euclidean geometry has long ago been abandoned in contemporary number theory. I suspect that it was completely gone by the end of the 19th century, at the same time as they dumped Euclid's Elements. I have never had to carry out arithmetic using a straightedge and compass, like the Greek in antiquity apparently did.alcontali

    And what do you think lead to that move? Metaphysics.

    I believe that there must be ingredients in the process of knowledge discovery that are fundamentally unknowable, because if we could know them, then we could even systematize the discovery of new knowledge, while this is fundamentally not possible.alcontali

    This would only be the case if you restrict the act of knowing, in the manner that you have proposed. Let's say that there is a system or method for producing knowledge, the axiomatic system you described. The system cannot know itself, so the "ingredients" of knowledge which are unknowable, as you say are those things which comprise the system. A logician cannot know what makes the logic employed, work, without going outside of the logic. So this is why metaphysics is important, it employs a completely different method, to evaluate the axiomatic systems. If it were a specific system which metaphysicians employed, then metaphysics would run into the same problem. Metaphysicians do not use any specific system, it is more like intuition, so metaphysics appears to be random nonsense to the uninitiated.

    Yes, I did refer to non-knowledge mental faculties. Intuition is clearly one.alcontali

    It is necessary to distinguish between knowledge, as an object desired or possessed, and the activities which bring knowledge into existence. When we allow for the existence of non-knowledge based mental activities, we allow for a process which could bring knowledge into existence. If, for simplicity sake, we generalize and call this intuition, then we have something named, which we can discuss, and analyze toward understanding it. We can say now, that principles, axioms, are not chosen arbitrarily, but they are chosen by intuition. Intuition would assess the applicability of various possible principles, in relation to various goals, ends. Now we have separated the means from the ends, and this produces the necessity of assessing the ends themselves. That's the endeavour which pragmatism forces onto the metaphysician. Pragmatism brings light to the fact that axioms are chosen for a purpose, now the metaphysician must identify and evaluate the purpose.

    For example, they did not start building the first computers because there were errors in the old mechanical calculators that preceded them.alcontali

    Since a machine is designed to give the human being what one wants, the inability of a machine to give the human being what the person wants, is an error in the machine. It is not an error in the machine's processing activity, but an error in the design. You might say, that an error in design is a human error, but all errors are human errors, and if the machine's processing activity screws up, it is just an error in design.
  • Determinism vs. Predictability
    The universe would be the closed system.Harry Hindu

    The existence of free will demonstrates that the universe, as we know it, is not a deterministic system, nor closed system. To say that there are multiverses which comprise a closed system is nonsense, indicating that you do not know what a "system" is..

    The car is epistemically deterministic in the sense that the problem can be identified and the car repaired or an irreparable part replaced. On the other hand the human body is not like this; many things can go wrong that we do not fully understand and repair is often impossible.Janus

    The fact that human beings can identify the problem after the fact, and repair it by replacing the worn parts, does not make the system deterministic. After all, human beings built the system in the first place, and it is the fact that the machinery will break down which makes it non-deterministic.
  • Metaphysics - what is it?
    Irrational just means that a number cannot be reached by merely applying the standard arithmetic operators (+ - x /) to integers.alcontali

    "Irrational" refers to an incommensurable ratio. This means that the two things being related to each other cannot be measured by the same system of measurement, such as the examples I gave you, the circumference and diameter of a circle, as well as the sides of a square and it's hypotenuse. What this indicates is that there is incommensurability between one spatial dimension and another.

    Still, the algebraics are not enough when you look, for example, at the roots of polynomials with rational coefficients. You will need to keep adjoining additional field extensions if you want to close the splitting fieldalcontali

    And you claim that the efforts of the metaphysician are pointless due to infinite regress. It appears like in reality the efforts of the mathematician are pointless due to infinite regress.

    So, in this context, "irrational" just means that the problem cannot necessarily be solved by using basic arithmetic, but that it may requiring adjoining to the rationals Q, other numbers produced with more complicated operations.alcontali

    You mean the problem can be solved by hiding the infinite regress behind "complicated operations". A good metaphysician is trained to recognize such sophistry.

    Existing knowledge cannot possibly be the main ingredient in the discovery of new knowledge, because in that case humanity would never have discovered any knowledge at all, or else, discovered all possible knowledge already.alcontali

    I see we agree on something anyway.

    We simply do not know how to discover new knowledge, and we can certainly not justify how we managed to do it anyway.alcontali

    But we do know how to discover new knowledge. It is basically a process of trial and error. It requires an assumption, a presupposition, which is not taken as true or false (knowledge), but is taken as a principle to be tried, like an hypothesis. You explained this above, in your explanation of what science is.

    The issue here, between us, is where do these principles to be tried come from. We cannot just choose them randomly because there would be an infinity of possibilities. Therefore we must proceed with some guidance in choosing the principles to be tried, this is metaphysics. The metaphysician recognizes the failures, errors of others, and narrows the pathway with this form of trial and error.

    Gödel's first incompleteness theorem also provably dismisses the idea of running through all possible well-formed formulas as to question a knowledge machine whether the formula is provable or not. For example, in the language required to axiomatize the existence of numbers, it is possible to produce formulas that are logically true but impossibly provable by the knowledge machine. So, if you enumerate the well-formed formulas in that language (which happens to be first-order logic), from first to last, the knowledge machine will run into examples of formulas of which the provability is simply undecidable.

    So, it is just not possible to run new candidate knowledge claims through a knowledge machine filled with existing knowledge to check if these new claims happen to be justifiable. Gödel proved that this is not a legitimate knowledge discovery procedure. We will undoubtedly have to keep doing it with leaps and bounds, through serendipity, trial and error, and what have you, to slowly, gradually, and painstakingly, but surely, acquire new justifiable knowledge claims.
    alcontali

    This is exactly why we cannot choose the principles to be tried, arbitrarily, as you seem to think that we do. We need some intuition as to which of the proposable principles are credible. This comes from a thorough examination of the existing knowledge, the flaws within reveal the errors, and therefore where new proposals are required. So your "knowledge machine" requires a method of analysis of the already existing knowledge to determines errors. This is where new knowledge comes from, determining errors in the old knowledge, not from introducing new proposals and checking for consistency with the old. A new proposal which is inconsistent with the old knowledge is not necessarily wrong, it could be that the old knowledge is wrong.
  • Determinism vs. Predictability
    I agree, but from what you've said, I think you and I have different reasons for thinking so.T Clark

    That we come to the same conclusion from different approaches is good support for the conclusion.

    For example, the internal combustion engine is epistemically deterministic. That just means it is a simple system whose function is reliably predictable.Janus

    It isn't though, because the car breaks down when you least expect it. You're over simplifying "deterministic", and "predictable", in order to say that if you can predict something there is a deterministic system involved.
  • Metaphysics - what is it?
    That is only the nature of falsificationist knowledge. That is absolutely not the nature of axiomatic knowledge. The Pythagorean theorem was provable 2500 years ago. It still is provable today. The same holds true for Thales' theorem. It is as provable today as 2500 years ago. Once provable, always provable. Hence, that particular view on the nature of knowledge is epistemically completely incorrect for axiomatic knowledge.alcontali

    When the two sides of a right angle are of equal length, the hypotenuse is irrational. Therefore the Pythagorean theorem as a first principle of geometry is deficient. Pythagoras himself grappled with this problem, and the fact that he could not resolve it bothered him. That the hypotenuse remains irrational indicates that the Pythagorean theorem remains unproven, just like the value of pi remains unproven.

    For mathematics, these rules are arbitrarily chosen.alcontali

    If the rules are arbitrarily chosen then why choose a rule which results in the contradiction which is an irrational ratio? The fact is that the rules are not really chosen arbitrarily, they are chosen for purpose, pragmatics. The circle is useful, and pi is the result of the rule which creates the circle. The right angle is useful for making parallel lines, and the Pythagorean theorem is the result of the rule which creates the right angle. That each of these results in an irrational ratio indicates that they are lacking in truth and reality, despite the fact of being very useful.

    So, then where is that elusive progress visible? Any link?alcontali

    I gave you the example, we now have a better understanding of the solar system. If you are unfamiliar with metaphysics behind this, you are not the only one. But that's because few people today study ancient metaphysics, they prefer modern metaphysics.

    The initially hypothetical knowledge was very often stumbled upon, through serendipity, trial and error, and sheer luck.alcontali

    Actually, most of the initial hypotheses are sheer metaphysics. Take a look at Einstein's special theory of relativity for example. And today there is much metaphysical speculation into the nature of the universe, and the micro world of quantum mechanics.

    So, yes, a better understanding of the solar system and other parts of the visible universe took a lot of observation. In fact, it first took quite a bit of haphazard progress in optics and construction of telescopes just to be able to observe these things in sufficient detail. So, yes, if they had had proper telescopes 2500 years ago, they would obviously have seen it too. It wasn't a problem of following the wrong principles at all.alcontali

    Actually, telescopes came after it was theorized that the earth revolved around the sun, and not vise versa, so understanding the heliocentric nature of the solar system was not the result of telescopes. The idea was floated around 2500 years ago, but the planets were given perfect circular orbits according to the principles of Aristotelian metaphysics. The assumption of perfect circles resulted in inconsistencies which could not be reconciled until Copernicus. The point though, is that metaphysical theory preceded the fine tuning observations which were required to adjust the theory.
  • Determinism vs. Predictability
    Sure, I can see that the equations may be strictly deterministic. but that doesn't mean the system in the real world is.T Clark

    That's right, there is no such thing as a completely deterministic system. That's a fantasy.

    (1) No ontological uncertainty in deterministic systems because...fdrake

    There is a very real problem with this assumption, and that is that such a system is not real. A system cannot be completely deterministic, because it is always subject to outside influence. A completely deterministic system would be a completely closed system, which is impossible to construct, and even if it does exist somewhere naturally, it couldn't be observed. There is no such thing as an absolutely "fixed", or determined system, so it makes no sense to talk about what does or does not exist within such a system.

    Of course, that's the nature of knowledge. Proceeding from the first principle has a similar problem,. There's no infinite regress, just some degree of uncertainty within knowledge, such that knowledge is forever evolving as we move forward.

    The most widespread and successful approach to morality is what the three offshoots of second-temple judaism propose, i.e. religious law.alcontali

    OK, now the point is that someone must determine the rules, the law. It makes no sense, to argue as you do, that all respectable knowledge proceeds from first principles in an axiomatic way, because this neglects the fact that someone must determine the principles, in the first place, from which the axiomatic knowledge will proceed.

    If you assume that all of the first principles for all divisions of knowledge have already been produced, this contradicts your original statement above, that we cannot know it's really "true", and therefore we must keep searching, in an endless way. You can't argue both sides of the contradiction. But this fact, the fact that we cannot know with absolute certainty that the accepted first principles are really true, is the reason why there is always a need for metaphysics. We cannot just accept as absolute truth, the first principles from which we proceed, in the other forms of axiomatic knowledge.

    Read up on it, and then you will understand that what you are doing in the realm of morality, i.e. "metaphysics", is just un-methodical bullshit. Seriously, that is why there has been no progress whatsoever in metaphysics for over 2500 years. That was to be expected, because there is simply no logic in that madness.alcontali

    Metaphysics does not operate on an axiomatic system, as I explained above, so whatever it is that is forbidden in axiomatic systems is irrelevant to metaphysics.

    The metaphysicist is wasting his time, simply because the direction of reasoning is necessarily incorrect.alcontali

    Unless you can justify this claim, it's nothing more than an opinion of an uneducated person.

    Justifying the starting-point rules is an exercise in infinite regress and futility. Can you give even one example of where an approach like that has worked?alcontali

    I gave you the example, moral ethics.

    Epistemology really works, while metaphysics is nonsense. We know that for a fact, because after 2500 years of metaphysics, it has never produced anything else but nonsense.alcontali

    I see, morality is nonsense to you.
  • Determinism vs. Predictability
    That a coin toss is random is entirely a real, and not artificial property of a series of coin tosses.StreetlightX

    A coin is something natural?

    What happened to you claim that "randomness can only be spoken of in relation to a fixed system"? A "fixed system" is an artificial system.
  • Determinism vs. Predictability
    One thing that follows from this understanding is that randomness can only be spoken of in relation to a fixed system.StreetlightX

    This is important, randomness is only a property of an artificial system. It is something created. The randomness in QM and other microsystems, discussed in this thread, is a property of those systems which have been created by physicists. Randomness itself, because it only exists within the confines of a created system and therefore cannot be absolute, is necessarily determined in the sense of being created intentionally. That is why it is an epistemic, and not an ontological matter. It only takes on the appearance of an ontological issue, as an illusion, when misguided metaphysicians such as C.S. Peirce, posit randomness as a fundamental ontological principle.

    Such misinformation is good reason for outrage.

    People thought the purchase of Alaska was stupid. The Danes sold the Virgin Islands to the US for $25 million. These aren’t stupid ideas and the outrage about it was misinformed.NOS4A2

    The stupidity is in the method, making it publicly known that I want to buy Greenland, instead of discussing this possibility with those who currently govern that land. How would you feel if the rich guy from a couple of neighbourhoods over, was going around telling everyone that he was intending to buy you out of your house? Any misinformation here is the fault of the president. But why would the president misinform his own people?
  • Metaphysics - what is it?
    Reasoning from first principles in the context of the real, physical world looks like a serious epistemic mismatch to me. That is why I reject the practice of metaphysics.alcontali

    But metaphysics is reasoning toward first principles, not reasoning from first principles.

    For example, the axiomatic method certainly does an excellent job in mathematics; but it also does an excellent job in morality, where axiomatic derivation from basic rules is also the method of choice.alcontali

    Here is evidence of your mistake. Morality, in the sense of being moral, acting morally, may be described as a matter of behaving within the confines of some rules of ethics. But to study morality, as a field of study within philosophy, is a process by which we seek to determine those rules. The same is the case with metaphysics, many people, including physicists and other scientists, will reason from first principles in their endeavours, just like many people behave morally, but the metaphysician reasons toward determining first principles.
  • Absolute rest is impossible - All is motion

    I don't see how that is relevant to absolute rest.
  • Of stillness and death, Of motion and life
    Why then the emphasis on stillness?TheMadFool

    As I said, it's an exercise of will power.
  • Validity of the Social Contract
    I think the ‘misunderstanding’ is due to equating ‘leisure’ with ‘freedom’I like sushi

    I didn't equate leisure with freedom, that's another example of your misunderstanding. What I implied is that one must have leisure in order to act freely, if "leisure" is defined as "free time".

    I think freedom is the capacity to carry out free acts. Since time is necessary for activity, free time is an essential aspect of freedom. What did you have in mind as a definition of "freedom"?
  • The Difference Between Future and Past
    Sensations, incongruous feelings, memory, anticipation, planning, the observed passage of cause and effect... These are all what past and future 'really' are because they are all what we use the terms 'past' and 'future' to describe.Isaac

    This is randomly composed nonsense. The observed passage of cause and effect refers to the past only. That is the point of the op, empirical knowledge, knowledge based in observation, refers only to the past. If we want to apply this knowledge to the future, through the application of prediction, we must employ some other principles. These principles are not derived from observation. This is because there is a difference between future and past which cannot be understood through observation.

    Past and future are just words. We can use them to describe whatever phenomenon we like, so long as we're understood.Isaac

    This is blatant contradiction. If being understood is a condition which restricts how we use these words, then we cannot use them however we want.

    How are you going to demonstrate that anyone has the answer right?Isaac

    This is philosophy, why must one be looking to find "the right answer"? I'm looking for suggestions, possibilities, not the right answer. I don't believe that any human being is capable of giving the right answer because I believe that this is something unknown to all human beings. But why should this prevent me from investigating, looking for ways to proceed into the unknown. Isn't that what philosophy is?
  • Absolute rest is impossible - All is motion

    But you still have not provide a coherent definition of absolute rest. As I explained earlier, there could be something which everything else is in motion relative to, but is not itself in motion, and this is absolute rest. How do you show that this is impossible?
  • Validity of the Social Contract
    The point of it is that we have to give up individual freedoms in order to live together in harmony.I like sushi

    Actually, I think that this is where the misunderstanding lies, not in the conditions of "social contract", but in the misunderstanding of "individual freedom". In actuality, living together under a social contract produces freedom, through the process commonly represented as the division of labour. To act freely requires time not dedicated to providing for the necessities of living. There is no fundamental difference in individual freedoms between life with or without a social contract, but the social contract provides people with the capacity (time) to act freely.
  • Of stillness and death, Of motion and life
    Very recently I saw a tiny praying mantis and as I approached it it sensed my presence and immediately froze. It stopped moving completely. This is, if I'm correct, death mimicry. Dead or lifeless things don't move.TheMadFool

    Suzuki-roshi, in his well-known book Zen Mind Beginners' Mind, indeed says that the practice of zazen is to sit perfectly still, but completely alert, like a frog waiting for a fly to appear.Wayfarer

    There is a difference between being still to avoid being preyed upon, and being still in order to prey, but neither involves an inactive mind. Both, I see as an exercising of will.
  • Cosmology and "the prior"
    Is it possible to describe the origin of the material world in materialistic terms only?Gregory

    Materialism conceives of the world strictly in terms of material objects. The problem which this comes up against is that we see that all material objects have a beginning and end in time, and they also require a reason for their existence, a cause. If we take the whole of material existence, and look at it as an object, the universe, then we see that there must be a cause of it which is immaterial. This is represented in a more comprehensive way as the cosmological argument.

    Modern physics takes us beyond materialism by understanding the world in terms of energy. Acceptance of the terms of modern physics renders materialism as obsolete, so physicalism has superseded materialism. The problem which physicalism has, is that "physical", just like "energy", is a property of things. In relation to the universe then, as a thing, energy is a property of the universe. And, it is impossible to adequately describe a thing by referring to a single property, nor is it possible to determine a thing's origin through reference to a single property.
  • The Difference Between Future and Past
    Well, there you go. Your intuition tells you they are different. The fact that we can't measure that difference is unproblematic for you because you already believe that not all knowledge is measurable. I'm not seeing the problem you're trying to resolve.Isaac

    I don't really think it's known by intuition, I used intuition as an example of knowledge without measurement. If it's intuition, then what type of knowledge is intuition? I think many would say that intuition doesn't even qualify as knowledge. Do you think that intuition qualifies as knowledge? Why is it so often wrong if it's knowledge? I said it was self-evident. And self-evidence gives us certainty, intuition does not.

    Supposing that each of us always carried a mobile phone and that we agreed to eliminate "the present", "now", " currently" etc. from public discourse by replacing each of their uses with the exact current reading of the International Atomic Time supplemented with the Gregorian calendar. Likewise, we respectively do the same for "the past" and "the future" by replacing their use with time-intervals that are before or after the exact current TAI time.

    Doesn't this elimination of temporal indexicals also eliminate all talk of change, and therefore reduce MacTaggart's A series to his B series?
    sime

    I see a problem with this scenario. If it eliminates talk of change, then it denies us the capacity to talk about, and understand, this aspect of reality, change. Furthermore, it creates a very artificial "time" which is not consistent with what we experience. What we experience is that if we want to be precise, then by the time we say what time it is, it is no longer that time. And if we limit ourselves to very vague designations of the time, like "it's a little after six", or, "it's Tuesday", we rob ourselves of the precision which is needed in some instances. So doing this would be making a move away from understanding time.

    Actually, it is my opinion that looking at this as a question concerning "time" is a mistake. I am not looking at any type of series, as described by McTaggart, what I am looking at is what is evident to us, and this is that there is a past, and there is a future. If it is the case, that we have to turn to a series, some sort of ordering of events, to understand this future and past, then I would like to see the logic behind that. But right now I see no need for this. I understand that there is a future for me and a past for me, and I apprehend these as radically different, so this necessitates an assumption of something that separates them, that is the present. Until I validate this difference between future and past, I have no claim on any "present", and no principles for talking about the present being extended in "time". Isn't that all that "time" is, the extension of the present?

    The only possible method by which to study temporality is to approach it as a totality, as an original synthesis, which dominates its secondary structures and which confers on them their meaning.Number2018

    My method for studying things is analysis, dividing things into parts and trying to see what makes the parts fit together as a unity. What makes you think that this method is not suited for studying temporal issues?
