  • Pedantry and philosophy
    I think we'd probably agree that when Bill Clinton protested "It depends on what the meaning of the word "is" is, he was being pedantic. We could, however, also note that figuring out what the meaning of "is" is, is basically shorthand for the whole enterprise of metaphysics.Reformed Nihilist

    Which is precisely why some have alleged that Western Metaphysics is inherently phallogocentric ;-)
  • Why does determinism rule out free will?
    No it isn't. There are either different senses of responsibility being used, or it's the same sense and there are simply different penalties.Terrapin Station

    ...and a different phenomenology, obviously. But the point is moot if you aren't conceiving of your own alleged sentiment of responsibility when you are sneezing as something akin as a strict liability. Are you? If not, are you also feeling responsible for your arm rising if someone else suddenly grabs it and raises it? If not, what's the difference? Is endogenous production of bodily movements sufficient, in your view, for your feeling responsible for them?
  • Why does determinism rule out free will?
    I wouldn't say that those are using the idea of responsibility differently, though. They apply different legal upshots to responsibility based on whether something was voluntary or not, but it doesn't seem to me that they're employing different senses of responsibility.Terrapin Station

    Whether you are conceiving of them as different ways to apply of the very same concept, or different senses of 'responsibility', is rather beyond the point. We were discussing the phenomenology of action. There is no special phenomenology that attaches to the unintended production of an effect that you are responsible for due to a context of strict liability. You may not even be aware that this effect is being (or will be) produced until long after the fact.
  • Why does determinism rule out free will?
    I wouldn't say there are different senses of responsibility that I'm using in this regard.

    What different sorts of senses of responsibility are you using?
    Terrapin Station

    I already provided the example of strict liabilities, a legal concept that can rather straightforwardly be extended to cases of ordinary life, e.g. when we accidentally bump into someone and incur a felt obligation to apologize. Likewise if we would sneeze during a quiet moment at a public recital. Another sense attaches to the voluntary production of intended results when we act intentionally. I would have guessed that it's not quite in that sense that you mean that you feel responsible for sneezing.
  • Why does determinism rule out free will?
    You made the claim that people do not feel responsible, on a personal level, for events such as sneezing.

    I said that that's not the case for everyone. I said that I feel responsible, on a personal level, for events such as sneezing.

    That doesn't require an argument. It's simply a fact that I feel responsible for sneezing when I sneeze, and many other people I know would say the same thing.

    So then you wanted to change it to whether responsibility for voluntary actions is the same as responsibility for involuntary events. Obviously it's not in a very trivial way: namely that voluntary actions are not the same thing as involuntary events. Of course, this has nothing to do with the claim you'd initially made, which was simply that people do not feel responsible, on a personal level, for events such as sneezing.
    Terrapin Station

    No. I didn't "want to change" my initial claim with another claim. You have not been paying attention. From the very start my point was to contrast the phenomenology of actions with the phenomenology of involuntary behaviors or of unintended bodily motions: things that merely happen to us. Here is what I had said again:

    "We feel like there is a difference between the actions that we performed because we voluntarily chose to do them, and the events happening to us (and to our bodies) which we aren't responsible, on a personal level, for having brought them about (e.g. so called involuntary 'actions' such as sneezing, say)."

    Also, I didn't ask you to justify your feeling that you are responsible for your sneezes. I asked you in what sense are you feeling responsible for them. That would help me to assess if the phenomenon of sneezing constitutes a counterexample for the general thesis that I meant to illustrate, or if, rather, they just aren't a good example and I ought rather to pick another one. It is difficult to imagine that the former rather than the latter might be the case unless you really mean to suggest that people feel responsible for all their consciously occurring bodily movements and reflexes regardless of their involuntariness.
  • Why does determinism rule out free will?
    And do you care if your observation is wrong?Terrapin Station

    I would care if you would supply an argument rather than just a bold claim that seems to rest on a conflation. If you won't care to explain in what sense you are holding yourself responsible for your own sneezes, then it is difficult for me to evaluate the philosophical import of this alleged counterexample to a prima facie quite uncontroversial observation.
  • Why does determinism rule out free will?
    So no concern with issuing claims about how people think about something when it's clear that some people don't think about it that way?Terrapin Station

    I hadn't anticipated that you would object to my observation that people hold themselves (and each other) responsible for their voluntary actions in a way that they don't for their involuntary behaviors. You suggest that I am unjustifiably projecting my own personal sentiments since you yourself feel responsible for your own sneezes. It may make sense for you to say this if you are conflating responsibility for intended actions with strict liabilities for their unintended consequences. Strict liabilities are a thing, for sure, but they don't normally figure in the phenomenology of action (let alone in the phenomenology of involuntary behaviors) until after their unintended consequences (if any) have occurred.
  • Why does determinism rule out free will?
    I don't see how that's not projection on your part. I feel as responsible for my sneezing, say, as I do for choosing to respond to you again in this thread.Terrapin Station

    Maybe if you would put a little more thought in your replies, and a little less anger, it wouldn't feel like you were sneezing. But if you would rather elect not to sneeze in my direction anymore, I have no objection to that either.
  • Why does determinism rule out free will?
    BBC discussion covers a lot of ground:

    www.bbc.co.uk/programmes/b00z5y9z
    FreeEmotion

    Thanks for that again! You always find interesting stuff. A discussion involving Helen Beebee, Simon Blackburn and Galen Strawson ought to be interesting. The three of them are very smart and articulate even though Strawson's hard deterministic view seems rather deeply misguided to me.

    Beebee wrote an engaging introduction to the topic: Free Will: An Introduction, Palgrave Macmillan (2013). The very short conclusion of her book might be worth quoting in full:

    "If you’ve managed to get this far, you now really know quite a lot about the contemporary debate about free will. More importantly, I hope you are now armed with the resources to decide – provisionally, of course! – what you think. Is free will compatible with determinism, and, if not, which kind of incompatibilist view is right? More importantly – or so I think – is it plausible to think that we actual human beings routinely act freely? And, if not, what consequences does that have for our responses to, and relationships with, other people, and for our conception of ourselves? My own (again, provisional) general view is, I think, clear enough; but, of course, you most certainly should not take my word for anything. One of the great joys of philosophy is that you don’t have to take anybody’s word for anything . Of course, that also poses a major challenge: When so much is up for dispute, it’s hard to know where to start. Overall, however, I think it’s more of a blessing than a curse. I hope you agree." -- Helen Beebee
  • Why does determinism rule out free will?
    On my view there's nothing particularly interesting about moral responsibility with respect to the free will issue, because there are no facts about moral responsibility. I find the free will issue interesting simply because of the ontological question--whether freedom is even possible, and then it's interesting with respect to just how will phenomena would be connected to ontological freedom.Terrapin Station

    It seems to me that even if one is an eliminativist, anti-realist or error-theorist regarding personal responsibility for one's own actions, it still figures as an inherent part, not just of our self-conception as rational agents, but also, quite prominently, in the phenomenology of practical deliberation, conscious choice and voluntary action. We feel like there is a difference between the actions that we performed because we voluntarily chose to do them, and the events happening to us (and to our bodies) which we aren't responsible, on a personal level, for having brought them about (e.g. so called involuntary 'actions' such as sneezing, say). One issue for the libertarian is to explain how this phenomenal distinction between deliberate choices or intentional actions, on the one hand, and things that merely happen to us, on the other hand, is to be explained such that intentional actions aren't merely occurring non-deterministically but rather constitute exercises of the agent's own abilities to chose to do them and thereafter remain in control of them. Such an account still has to contend with the problems of control, luck and intelligibility regardless of one's metaphysical stance regarding specifically moral responsibility, or so it seems to me.
  • Why does determinism rule out free will?
    This is a peculiar consideration, really, because if we don't have free will then whether or not I hold you responsible/punish you is also determined and not something I freely choose to do.Michael

    It's true that if determinism is true, and agents have no alternative possibilities (abilities) for doing otherwise than what they actually do (or judge), then Kant's formula appears to lead to a contradiction (or rather, to an imperative that can't be consistently obeyed in conjunction with the knowledge that determinism is true) when applied to the act of holding people responsible. So, there are three solutions to this. (1) Deny Kant's formula (and thus also PAP). (2) Deny determinism. And (3) provide a sensible conception of rational abilities (and thus of "can") such that PAP is consistent with determinism. (Kant seems to have endorsed (2) in the Critique of Practical Reason, saying that freedom is a postulate of practical reason; although the Third Antinomy in the Critique of Pure Reason might be read as a proposal for (3) accomplished through distinguishing the empirical character of causality from the intelligible character of causality.)
  • Fitch's paradox of Knowability
    What is driving
    At (6) they get a contradiction and from that we can prove every statement (can't we?)
    But they keep proving for 5 more steps for no apparent reason.
    Meta

    There is a good reason actually. It's because (6) is a contradiction that the premise of the argument must be discharged: that is, negated. That's how reductio proofs work. Step (7) just is the negation of the premise that logically led to the contradiction (assuming the validity of all the deductive principles that had been used in the previous steps).

    (On edit: this was of course a comment regarding the proof as presented in the SEP article linked in Meta's post.)
  • Why does determinism rule out free will?
    You don't have to accept that any stance on free will versus determinism has any particular implication re moral responsibility.Terrapin Station

    The relevance comes from the Kantian 'ought implies can' formula according to which you can't hold responsible someone for having done something that she could not possibly not have done (i.e. didn't have the power to refrain from doing, or didn't have an opportunity to so refrain). But it is true that this requirement can be satisfied by both (some) compatibilist or incompatibilist accounts of free will. Some philosophers (e.g. Alfred Mele or John Martin Fischer) are semi-compatibilists; they hold moral responsibility to be compatible with determinism although it isn't precluded by the lack of abilities to do otherwise. They would thus deny the validity of the 'ought implies can' formula. (So called 'Frankfurt cases', popularized by Harry Frankfurt, constitute alleged counter-examples to the formula.)

    Myself, I think the mere self-conscious ability to reflect on one's own rational responsibility for the authorship of one's own past, present and foreseen actions, choices and intentions is the source of the 'ought implies can' formula (and the PAP principle); and the application of this formula to specifically moral considerations just is a dramatic but special application of this rather profound metaphysical fact about rational agency. (I also hold morality to be an integral part of rationality rather than its being extraneous as a mere source of extra-rational conative attitudes, but that is a separate matter).

    Of course, one big reason for this is that there are no facts re moral responsibiilty.

    It's possible that you are an agency incompatibilist, like Helen Steward. You would thus hold the core issue regarding the problem of free will and determinism to be an issue for animal agency in general. But even agency incompatibilists usually recognize that free will is best construed as a special form of agency that only rational creatures enjoy and that makes then responsible for their actions in a way animals who can't help but behave in accordance with their own natures (however non-deterministically) aren't.
  • Why does determinism rule out free will?
    Nozick would disagree:Michael

    Yes, the problem for libertarian free will that Nozick raises is this passage is the luck objection. I had mentioned this objection as well as the closely related 'intelligibility problem' and the issue of 'agent control' in this post.

    It is somewhat unusual to cast this problem as a threat to the value of human life in the way Nozick does. Terrapin Station's dismissal of it on the ground that values are subjective isn't really to the point.

    Also, allowing agents to somehow gain indeterministic control over their actions through there existing a bias in the probabilities of the different courses of action that they can possibly follow doesn't seem to ensure that they have the ability to do otherwise that underscores personal responsibility. For, in that case, while the agent who *might* have achieved an unintended result (when she actually intended to achieve the most probable result) doesn't thereby possess an ability to do so. It's just something that could happen, just as the ability to hit bullseye may fail to be realized when a shooter misses. But if she had missed in circumstances where she was aiming at the center of the target, she wouldn't thereby have freely exercised an ability to miss.

    One way out of the problem of luck for the libertarian is to posit that the indeterministic branching occurs immediately before the time of the mental "volition", or the formation of the intention. But such accounts then run into the intelligibility problem, and the problem of agent control.
  • Why does determinism rule out free will?
    There is what seems to be an excellent explanation on the Free will determinism debate here:
    https://www.youtube.com/watch?v=vCGtkDzELAI

    I understand the concepts much better now - much clearer. The next video on Compatibilism was also very helpful.
    FreeEmotion

    I just watched both videos and they are quite good. Of course, they're introductory and very condensed, so many more subtle distinctions are glossed over, and there are a few inaccuracies. (Some of the inaccurate statements are very widespread, though, even within the recently published literature.)

    The doctrine of determinism is glossed as the idea that every event has a cause. But many philosophers will rightfully separate this idea (the principle of universal causation) from the different idea, more properly called determinism (or nomological determinism), that the state of the universe at one time, together with the laws of physics, jointly determine uniquely the state of the universe at any other times. Also, the Oedipus cases, as narrated in the video, seems to illustrate the idea of fatalism, or of the possibility of foreknowledge. Fatalism doesn't necessarily imply determinism, and neither does fatalism imply determinism. And finally, many philosophers have argued that the possibility of the foreknowledge of an agent's future actions (divine omniscient foreknowledge, for instance) doesn't imply fatalism or determinism either.

    Another simplification was the equation between libertarianism and the belief in the possibility of agent causation. Many contemporary philosopher now endorse varieties of 'agent causation' and also are compatibilists (and determinists). And there are also proponents of agent causation who take agent causation to be incompatible with universal determinism but who nevertheless accept the idea that every event has a cause. They reject the idea that agents have the "contra-causal" power to initiate new causal chains of physical events -- as explained in the first video -- (though actions may be construed as initiations of causal chains of other sorts, which supervene on the physical but aren't identical with physical events).

    Also, the discussion of 'Frankfurt cases' and of the principle of alternative possibilities (PAP) makes it sound like compatibilists all believe this principle to be incompatible with determinism, and hence believe free will not to require it. But quite a few contemporary philosophers, dubbed 'new dispositionalists' by their critics, endorse both compatibilism and PAP. They have, in other words, an account of what it means to say that an agent could have done otherwise than what she actually did, and their account is specifically designed so as to make possession of this ability (and therefore also PAP) consistent with determinism.

    There'd be more to say about what appears to me to be a misconception pertaining to the way agent-control relates to responsibility and free will in Patricia Churchland's account. But her views are very widespread and they are accurately reported in the video.
  • Socratic Paradox
    Your solution is quite similar to Russell's way to deal with the analogous instance of the Liar Paradox (Russell's paradox) that arose from attempts to realize the logicist program in the foundations of set theory (and of arithmetic). He devised the theories of types in order to solve the problem. In that case, the proposed solutions seem somewhat arbitrary and artificial. But in the case of your own solution, it seems to be more to the point since it is such a natural reading of the intent of Socrates' assertion.
  • Why does determinism rule out free will?
    Again, that P is logically possible is only the case to some S at some specific time, because of what logic is--namely, a way of thinking about the world. That doesn't imply that S can't think about the world when he does so that he thinks that P(t). But that doesn't imply that at t P(t) is true. It's not. It's only true to S, at the time that S thinks it.Terrapin Station

    This is indeed exactly how I understood your position.

    What it is to be logically possible or logically impossible is for some individual to think about things a particular way. There's nothing else to it.

    But you are claiming something else. You are claiming that for something to be logically possible or logically impossible at time t there must not only be some individual who thinks about it, or be able to think about it (at some time or other), but, in addition to that, this individual must be thinking about it at time t.

    This is strange, but, coming to think more about it, it doesn't appear to be inconsistent. I still prefer the view that operators of logical possibility, just like operators of alethic, metaphysical or nomological possibility (but unlike operators of temporal or epistemic possibility) are tenseless. The view that they have truth values only at the time when they are thought about strikes me as somewhat idealistic or solipsistic rather than pragmatic. It also introduces a strange disconnect between logic and natural laws, as if natural laws weren't also pragmatic abstractions. But, again, nothing much hinges on this. At least I have come to see that your view may be consistent. So, let us agree to disagree.
  • Why does determinism rule out free will?
    <sigh> it's not also a logical possibility at the time in question.

    At the time in question, it's only a metaphysical possibility.

    This is because logic only exists once there are people. That's not the case with the world in general.

    This is relevant to there being an example of a metaphysical possibility that's not also a logical possibility. I'm not saying that it's relevant to anything else.
    Terrapin Station

    When you say that "something" is a logical possibility at time t, this can be interpreted in a specific way that is perfectly intelligible but that is clearly not how you mean it. This "something" must have the form of a predicate such that it may be true at some time and not at other times. For instance, some specific apple's being ripe would be such a predicate. This could be written R(...), where the argument place is a time variable. Then, saying that the apple's being ripe is a logical possibility at time t means that R(t) is logically possible.

    But what you mean is something different. You rather mean that the saturated expression R(t), (or rather the proposition that is expresses), not the unsaturated predicate R(...), itself may be logically possible or logically impossible depending on whether or not there happens to be human beings (or other sorts of logic users) in the temporal and/or spatial vicinity of the apple. I think this is nonsensical, and it is absolutely not required by the thesis that logic is human dependent, in a pragmatic or Kantian sense. The relevant sense of human dependence does't require that the objects thought about be in the spatial or temporal vicinity of the human beings evaluating the logical possibilities of propositions about them since our cognitive reach isn't limited to the present or to the surface of the Earth, say.

    But I am not going to belabor the point. We will have to agree to disagree. This excursus was rather off topic anyway.
  • Why does determinism rule out free will?
    The reviewer should ask why whether they weren't logical impossible or possible at the time matters to the author in the context of the article. Did the article have something to do with whether there was logic 100 million years ago?Terrapin Station

    Well, this is pretty much what I have been asking you in several recent posts. I have been consistent in my insistence that claims about the logical possibility of scenarios or propositions depicting the past have absolutely nothing to do with whether there was logic in the past.

    In our case, you asked for an example of a metaphysical possibility that's not a logical possibility, so I gave you an example.

    The metaphysical possibility that you offered was about the past state of our universe at the time when the first stars formed. It was about the "metaphysical" possibility that this state could give rise to the evolution of life. This is also a logical possibility since the possibility of live evolving from that initial state "(has nothing) to do with whether there was logic (billions of) years ago" (as you now seem to be acknowledging). The fact that there was no logic back then is no more relevant to the evaluation of the logical possibility of the claim, regarding the evolution of life, than it is relevant to the relative populations of different species of dinosaurs.
  • Why does determinism rule out free will?
    Right, logical anything, including possibility and impossibility, is always to someone, and not only that, but it's also going to be only relevant to the particular logic that person is using at that time. Logical possibility and impossibility do not obtain outside of that. Not on a coffee table, or to amoeba in the ocean, or 3 billion years ago, etc.Terrapin Station

    So, this means that on your view, Professor Station was correct and the logical criticism of the conclusion of the study by the reviewer was misguided. The editor of the journal should publish the study without any revision since the result hasn't been shown to be logically invalid. It was not logically impossible that there were more triceratops than pterosaurs, more pterosaurs than velociraptors, and also, more velociraptors than pterosaurs. Our contemporary logic just doesn't extend to the distant past.
  • Why does determinism rule out free will?
    Again, I do not agree with this. Do you understand that I do not agree with it?Terrapin Station

    Of course, this is precisely why I present arguments as to why this claim that you are disagreeing with is reasonable and why your disagreeing with it leads to absurd results. If you are not agreeing with the idea that the truth of logical propositions isn't temporally bounded, then you must be agreeing with the defense provided by the author of the paleontological study. You must also be agreeing with the claim that scenarios that are logically impossible on Earth, those very same scenarios, are not logically impossible on Mars. If fact, they are not even logically impossible on the coffee table between us (assuming we would have had a conversation over coffee) since there is no logic literally 'on' the coffee table.
  • Why does determinism rule out free will?
    Why are you having a problem answering whether during the first star formation, there was logical possibility?

    If there's no logic, is there logical possibility?
    Terrapin Station

    If there is no logic, there is no logical possibility, but there is logic: our logic. And the truth of modal logical claims is not temporally limited anymore than it is spatially bounded.

    Imagine that a team of paleontologists comes up with the following discovery about the past: At some point during the Cretaceous, over a period stretching more than one million years, the average population of triceratops was exceeding the average population of pterosaurs, which themselves were more populous than the velociraptors, which themselves were more populous than the pterosaurs.

    They thus submit their putative discovery to a scientific journal and one reviewer sends an e-mail to the main author of the study pointing out that their main result has the form of a conjunction of propositions making up an inconsistent triad. That's just not logically possible. The main author replies that it may very well be that this would be logically impossible now, but none of the three reported disjuncts are nomologically impossible, and it is irrelevant that their logical conjunction isn't logically possible now since it happened over 100 million years in the past, at a time when there was no logic.

    Upon receiving this reply, the reviewer scratches her head and ponders over what to respond to Professor Station.
  • Why does determinism rule out free will?
    I'm not talking about our perspective.Terrapin Station

    No but you are talking from our perspective. When we make claims of logical possibility regarding contemplated scenarios unfolding here or elsewhere, now or in the past or in the future, we are envisioning those logical possibilities from our own perspective.

    I'm talking about during the first star formation. It was a metaphysical possibility that life would evolve. It wasn't a logical possibility. So that's an example of there being a metaphysical possibility and that's not a logical possibility.

    You are again conflating two different claims. First, there is the claim that at the time of the first star formations there wasn't yet a practice of logical evaluation of consistency of propositions, validity of inferences, etc. (just as there was no musical or scientific practice, say). And then there is the claim that it was not a logical possibility that something occurred at that time. The first claim doesn't entail the second because logical possibilities don't have temporal boundaries anymore than they have spatial boundaries. If it's logically possible that there are more than two rocks on Earth, then it's also possible that there are more than two rocks on the surface of Mars regardless of the fact that there is "no logic on Mars" in the sense of there not being such a socially instituted practice over there.

    The task wasn't to give a "context-independent" example, and if that had been the task, I'd say that there is no such thing.

    So, the implied interpretative context, in all claims of logical possibility, is our own practice of logical evaluation of propositions and inferences. There doesn't exist this context-free 'view from nowhere' perspective relative to which a determinate scenario is nomologically possible but is neither logically possible nor logically impossible.
  • Why does determinism rule out free will?
    Great. So an example of there being a metaphysical possibility that's not a logical possibility is that during the first star formation, it was a metaphysical possibility that life would evolve, but it wasn't a logical possibility.Terrapin Station

    No. The contemplated scenario about the eventuality of life evolving from those initial conditions is both a nomological possibility and a logical possibility. The fact that there was nobody using logic doesn't make the scenario logically impossible from our perspective. Likewise for the scenario about there being an unknown uninhabited planet permanently hidden on the other side of the Sun. There being such a planet over there doesn't fail to be a logical possibility just because, according to you "there is no logic over there".

    When I acknowledge that if there is no logic then there is no logical possibility, I of course meant, not logic anywhere at anytime. But it's not true that there is no logic. There still is our logic, and it's the only logic that counts for the evaluation of our claims of logical possibility.
  • Why does determinism rule out free will?
    Why are you having a problem answering whether during the first star formation, there was logical possibility?

    If there's no logic, is there logical possibility?
    Terrapin Station

    If there is no logic then there is no logical possibility. But it is irrelevant to our claims of logical possibility regarding the past state of the world whether of not there "was logic" in the past. Our claims of logical possibility are our own. They are pegged to our interpretation.

    Likewise, our claims about the logical possibility about distant places in space aren't pegged to "the logic" at those places.

    If we ponder over whether it is logically possible that there are non-rational Martians on Mars and that the tallest Martian is taller than the shortest Martian, then it doesn't make sense to say: it's not logically possible on mars, because martians don't use logic. The reason why it's not logically possible is our logic, not anyone else's.
  • Why does determinism rule out free will?
    Right. So during those events, was it logically possible for life to evolve?Terrapin Station

    Why is your statement of logical possibility tensed? It makes sense to tense the proposition that the modal operator is operating on since this specifies the time frame of the events you are talking about. But why tense the modal operator also? If you mean to peg the interpretation of the concept of logical possibility to the understanding of whatever people might have been alive at that time (if any), then your question would be more conspicuously phrased something like:

    "During those events, was it logically possible for life to evolve from the standpoint of the people who were living at the time, if any?"

    The answer would be 'no' since there weren't any living people. But this is not what we mean when we say, for instance, that it is logically possible that, at that time, conditions weren't such as to prevent the future evolution of life. (And if conditions were such as to prevent the evolution of life, anyway, then the impossibility would likely be nomological rather then logical, or so it seems to me.)
  • Why does determinism rule out free will?
    So during those events--the first star formation, say, was there logic?Terrapin Station

    There was no logic, no music and no literature. But this has no bearing at all on the question, for instance, whether or not it is logically possible that there were roughly as many spiral galaxies as there were elliptical gallaxies. That's indeed logically possible, arguably. It is not, however, logically possible that there were more binary star systems than there were stars. In those statements, "there were" is past tense, but "it is" is intemporal. It is not pegged to a specific time but rather to our own interpretation of logical possibility.
  • Why does determinism rule out free will?
    Right, so do you think it's meaningful to say that the first stars were forming at "some specified time frame" in the past?Terrapin Station

    Yes. That's meaningful. But episodes of star formation are events. They are not points in time, and neither are they "specified time frames" existing on their own some time shortly after the big-bang.
  • Why does determinism rule out free will?
    Why would that be meaningful but it's not meaningful to say that things occurred 15 (or 18 or whatever age you accept) billion years ago?Terrapin Station

    But I quite agree that it's perfectly meaningful to say that things occurred billions of years in the past (I am just agnostic regarding the exact moment of the big-bang). But it is one thing to say that there were things happening over some specified time frame in the distant past, and it is another thing to say that there was a "point in time" at some specified moment in the past. It's the latter that I can't make sense of.

    In fact, I had been insisting that it is meaningful to say that there are distant past events that possibly occurred, as a matter of logical possibility, while *you* were denying it on the ground that there were no human being back then and hence that there was "no logic".
  • Why does determinism rule out free will?
    Would you say that there was a yesterday, and that it was before today, but after last week?Terrapin Station

    For sure. But that is just to say that it is meaningful to say that things occurred yesterday, and that they thereby occurred earlier than today and later than last week.
  • Why does determinism rule out free will?
    Right, so you'd also say that you can't answer meaningfully whether there was a time/a "point" in time (in quotation marks for a reason) that you had lunch or whatever meal you might have eaten yesterday?Terrapin Station

    That's correct. Because moments in time when specific sorts of events are truly said to have occurred are coarse-grained in a way that must be consistent with the typical duration of those events. For this reason, I happen to think that the idea of 'the present' as an unextended temporal location that separates the past from the future is unintelligible. For any meaningful use of the concept of the present, it has some sort of temporal 'thickness'.

    Right, so do you think that there was a time when the big bang occurred?Terrapin Station

    This question can't be answered meaningfully unless it is being interpreted within the conceptual framework of some fundamental physical theory. It's likely that in relation of such a framework, the question is formulated badly. The idea of a continuous linear ordering of moments in time, or of an initial moment, may break down.
  • Why does determinism rule out free will?
    I didn't write "or say at the moment of the big bang"?Terrapin Station

    Yes, OK, you said that also. That's not very helpful. Should we now be talking about space-time point singularities in the context of general relativity and quantum cosmology? You haven't explained how your question about there being, or there not being, a "point in time" at some specified moment in time, whichever it is, makes any sense.
  • Why does determinism rule out free will?
    Didn't I say "at the moment of the big bang" a couple times?Terrapin Station

    Not quite. You mentioned a moment shortly after the big bang. But then you are asking me if there was a "point in time" at that time. This is just like asking if there is a point in space in the corner of the room. But you've just mentioned such a point. How could there not be a specific temporal location "at the time" you just specified as a specific temporal location?
  • Why does determinism rule out free will?
    So you don't know if there was a "point" in time billions of years ago? Do you know if there was a point in time yesterday?Terrapin Station

    What does a "point" in time look like? This sounds like the propositional reification of an unsaturated predicate. I can tell you if there was a point in time when the sun was shining. Temporal point are rather like spatial locations. You can tell if there is something or other at this or that place or if there is (was, or will be) something occurring at this or that time. But mentioning a time and asking if there is a point in time at that time seems strangely confused. It's like asking "is there a 'point in space' in the corner of this room?".
  • Why does determinism rule out free will?
    Do you think it makes sense that there was a time billions of years ago, just after the big bang, say?Terrapin Station

    I am not sure exactly how to evaluate the proposition "there was a time billions of years ago". What would it mean for its being the case that there isn't "a time" at some point in the past?
  • Why does determinism rule out free will?
    At that time, not now where you're thinking about that time, is it logically possible for intelligent beings to evolve or not evolve? Yes or no. I'm not going to move on until you answer yes or no, despite how much you try to avoid doing so.Terrapin Station

    I've explained to you that your question conflates two different ideas. I've explicitly disambiguated those two ways to read the question. The answer, according to the first construal, is "yes". The second construal, which seems to be your intended construal, doesn't really make sense. In any case, it's not related to our ordinary understanding of logical possibility according to which it is logically possible that an atomic war could have wiped out humankind ten years ago and that the earth would have continued orbiting the sun.
  • Why does determinism rule out free will?
    Say it's 10 billion years ago or so.

    Is it logically possible at that point in time for intelligent beings to evolve or not evolve?
    Terrapin Station

    You must resolve the ambiguity between the idea of (1) its being logically possible (according our conception of logic, now) that something could have been the case at time t, and the different idea of (2) its being logically possible at time t that something is possible at that time.

    The second construal presupposes that there is something about the claim that must be indexed to the principles of logic that are being used by whoever happens to be alive, and sapient, at that time. But this is no part the the usual idea of logical possibility, where the criteria of logical consistency are our own criteria, and not the criteria of the creatures that may populate the contemplated scenario (if there are any).
  • Why does determinism rule out free will?
    It's not just imagined. Persons didn't exist at one point in the past. There was no logic. No logical possibilities. But there were metaphysical possibilities.

    It's not logically possible for no intelligent beings to evolve. If no intelligent beings evolve, there is no logic. You're assuming that logic is something other than a thing that intelligent beings do.
    Terrapin Station

    The claim that it's not logically possible for no intelligent beings to evolve conflates two things. It conflates the idea of this scenario not being logically conceivable by us, and the idea of this scenario describing a state of affairs where our logic (or anyone's logic) has not been invented and/or made use of within the imagined situation.

    Your claim doesn't make anymore sense than the claim that is it logically impossible for there to be distant planets where not life evolved, since in that case the is no logic on those planets.
  • Why does determinism rule out free will?
    I just explained this to you. Imagine that there are no people. There would still be metaphysical possibilities. There would be no logical possibilities. There would be no logic period.Terrapin Station

    This is not an example of something that is a metaphysical possibility and not a logical possibility. It's rather an imagined scenario (for instance, an alternative history where human beings didn't evolve) where nobody invented logic. But it is logically possible that no intelligent beings had evolved: for instance if a huge meteorite had hit the earth 100 million years ago and killed all the higher life forms. So the imagined scenario is logically possible. Else, you'd have to say that it's logically impossible for mankind to become extinct (unless other sorts of beings somewhere, on another planet maybe, still go on thinking logical thoughts). But logic alone doesn't rule out the possibility of mankind's extinction at some point in the future.
