    That's exactly what I'd expect. But notice that 'phenomena' means 'what appears'. Who it appears too is omitted by this, but I expect you think that 'only phenomena exist'.

    There's obviously a connection. I think the whole question of what constitutes a synthetic a priori judgement is still wide open.

    Thanks to Kant and his apriori/a posteriori and analytic/synthetic distinctions, we have an opening to prove the logical necessity of causality as a synthetic a priori truth!

    No. I was referring to physical phenomena, not to perception. If you choose not to trust your perceptions, that's an entirely different issue.

    I agree they exist in nature, within the objects that exhibit them. I have a problem with assuming they have independent existence, because that raises more unanswered questions.Relativist

    Maybe not within the objects themselves. Rather in their spatial relation with other objects, or the spatial relations of the parts of which the object is made up (in which case the lay within the object, in a certain sense)). We know nothing about the objects themselves. We call the contents of objects (and the objects they are made of, way down to the fundamental level) physical charge and mass. These contents we only get to know if we literally consume them and they become part of us.

    Regardless, 'phenomena' means 'what appears', 'a fact or situation that is observed to exist or happen'. That is a matter of definition. The idea that phenomena constitute the totality of experience is commonplace, but mistaken.

    Without causality, no life. Only if causality exists, life can exist. Life exists. So causality is an a priori logical necessity.

    No, they do not. Physical cause is not logical necessity. It is not modus ponens. You seem to me to continue to insist on something that is blatantly not the case, and yet not address this criticism.

    Physical causality is a logical necessity for life to exist. It's not a sufficient logical necessity though. But without it, life can't evolve in the first place.

    Hand up. At a slight tangent, it is relevant to the use of statistics in public health. Durkheim studied suicide rates and noticed that whilst each suicide is an individual choice made from personal motives the death rates from suicide in a population are remarkably similar from year to year. The cause of an individual event can be seen differently from the cause of a pattern or rate of such events.

    https://durkheim.uchicago.edu/Summaries/suicide.html

    I don't know whether it qualifies as a paradox. Random coin flips result in a predictable result of ever more approximately equal heads and tails.

    A different but related idea is the Prevention Paradox. To reduce the rate of heart attacks in a population the interventions need to apply to the whole population, people at low risk as well as at high risk.

    ‘Why do some individuals have hypertension?’ is a quite different question from ‘Why do some populations have much hypertension, whilst in others it is rare?’ — G Rose

    I award myself beta plus minus for the above. "It is an interesting connection but you did not relate it back to the original article." True. I leave that to others and anyhow I'm supposed to be working.

    ...but posted it anyway.

    Now it seems to me to set out in section (I) the "genealogy" of the error of equating cause and logical necessity, then in section (II) to show that determinism does not work in classical physics, that there can be uncaused events in more recent physics and to show that determinism is incompatible with freedom, and showing that determinism is a cultural artefact that is not needed for doing science.

    So it seems to me to be shining a light directly on the error of your OP. A puzzle then, that you did not find that light illuminating.

    I think I'm trying to articulate the nature of the relation between ideas and reality. I mean, it's presumed that ideas are 'in here', artifacts of the mind or culture, whilst the 'physical world' is 'out there', over which we cast our net of ideas and concepts, often to great effect. That is what I'm questioning. It's nothing like what Anscombe is concerned with.

    The Anscombe article shows that they are quite distinct things.

    Ah, Ok, so to the deeper issue. Isn't this a bit like trying to rationalise rationality? How to put into words the very act of putting things into words? Looks to me like something we show but not say; something at the very edge of language use. Something like that seems to be implicit in the last few paragraphs of Anscombe's article. I suspect that she has some Thomistic solution she is hinting at but not setting out, that might well be more in line with your approach than with mine.

    It wouldn’t surprise me if she did. And yes the issue is a metaphysical one. It revolves around divesting the world of reason. No coincidence that Hume is also associated with the -is-ought problem’. This is not fortuious.

    But to 'explain reason' is to invariably sell it short! As soon as you account for it in anything other than it's own terms, then you're denying the sovereignty of reason. I'm beginning to suspect that the very existence of reason is actually an inconvenient truth for a lot of analytical philosophy.Wayfarer

    This is why Banno characterizes (defines) "reason" as "a group enterprise", rather than as the activity of an individual mind. Instead of describing reasoning as something which an individual mind does, Banno describes reasoning as having the essential property of "language" (requiring, or needing language). This makes language logically prior to reasoning.

    Now, instead of the true description, in which individual reasoning minds use language as a tool, Banno has a group of people involved in an activity called reasoning, and the group are using language as their tool. The obvious problem with Banno's argument is that it is utterly impossible to locate, identify, and understand this group activity, called reasoning. Every time that we try to find and identify the activity of reasoning, we see very clearly that it is the activity of an individual reasoning mind. Therefore Banno's argument is based on a false description; the unsound premise that reasoning is a group enterprise.

    How this intuition of time, manifesting as order, is itself grounded, whether it is grounded in experience, or something more fundamental than experience, as prior to experience, and a condition for the possibility of experience, is probably an issue of how we define the terms.Metaphysician Undercover

    The whole comment was pretty good, but it all comes down to this, for which I can find no fault. As great and wonderful as human reason is, each of us has his own and he is at the mercy of it. Hence, you take the red pill in defining terms in one way, I take the blue pill in defining terms another way, while trying to find something in common. Which hardly ever works.
  • Metaphysician Undercover
    13.1k

    Maybe, the red pill and the blue pill actually consist of the very same thing?

    Actually though, I think there is a very real difference, which involves the relationship between space and time. As explained in my post, intuitively, time is logically prior to space. And for any person who takes a few moments to contemplate this question, in meditation or any other mystical practise, this intuition starts to become very clear. But in the science of physics, this order has been reversed, such that space is prior to time. Therefore we can conclude that our true intuitions must be suppressed for the sake of adopting the time/space relationship employed by physics.

    When presented with this problem, we can proceed toward resolution by assuming that our basic intuition of time is wrong, or by assuming that the representation of time employed within physics is wrong, (or both). But if we assume that our fundamental (base) intuitions are wrong, then we have nothing left to go on. We must dispose of the most basic principles of logic, such as identity, and non-contradiction, and we are left with zero, nothing as a starting point. Any chosen starting point, for any sort of understanding, would be completely arbitrary and randomly chosen.

    This is what "pure mathematics" gives us. It appears like we can choose any arbitrary starting point (axiom), and produce a synthetic conceptual structure based solely on One point. Order is not necessary, we can start at any given point. However, the nature of logic, and it's ground in intuition, really demonstrates to us that this is untrue. In reality we need more than one starting point. And, we need an assumed relationship between the plurality of starting points. If the relationship between the multitude of points is not assumed to be one of necessity, the entire structure has no logical stability.

    In turn, this reality show us something about "intuition" itself. It can be neither a priori nor a posteriori, but it must necessarily be a combination of both. That is what produces reliability.
