  • Understanding the Law of Identity
    Look at how the subject of identity is handled in formal logic, philosophical logic, mathematical logic, set theory, and mathematics. Those clear up a lot of questions (though there are still some philosophical questions that arise).TonesInDeepFreeze

    Precisely. In ordinary math we have an identity (valid for all or most values) and conditional equation (valid for a select set of values). 2(x+1)=2x+2 and 2(x+1)=3. Rough definitions.
  • Foundational Metaphysics
    So, in the sense you put it here, a bounded backward iteration with no end to the number of iterative steps would be what is traditionally called an actual infinite and unbounded potentialBob Ross

    It's simply a process that's unbounded. In math an actual infinite potential (I've never heard it called that - but I don't live in that mathematical world) is vague unless it corresponds to a cardinality. Tones-in-a-deep-freeze could go into this in a much more rigorous way.

    However, just to clarify, I am not defining an infinite nor bounded/unbounded infinities in that manner, but I could see them as less precise examplesBob Ross

    I would have guessed more precise. Give me an example from the real world of what you are talking about.

    Although I understand the point pertaining to the dispute amongst mathematicians over "potential" vs "actual" infinities, I am not sure how that objection relates to my essay. If you could please provide further elaboration, then that would be much appreciated.
    Bob Ross

    There's no significant dispute that I know of. Most of us not in foundations or set theory are not concerned with "actual" infinity. I assume what you are talking about is moving backward through causation chains with no recognizable beginnings. Like backward iteration in which there is no end to the number of iterative steps, but the process is either bounded or unbounded.

    Afraid I was gone by then. But reading about him I can see a connection with what Mihály made his life's work. Was there a common school of thought there about that time? Incidentally, about that time the physics department started teaching all the math courses for its majors. Must have been a bit of ill will between physics and math departments.

    Indeed, once science turns its attention to subjectivity and consciousness, to experience as it is lived, then it cannot do without phenomenology, which thus needs to be recognized and cultivated as an indispensable partner to the experimental sciences of mind and lifeJoshs

    I'm a little skeptical of a "science of mind".

    Phenomenologists reject the concept of objective research.

    However, this thread has made me aware of a new kind of mathematics supporting cognitive science,

    I was there at that time. I missed knowing Fine, but I did go climbing with Mihály Csíkszentmihályi, who later wrote extensively about a subject I discussed occasionally with him: "flow" in human activities. In particular, in gymnastics and climbing.

    Ok, here’s some contrivance for you:Joshs

    It's not surprising these are in the general area of cognitive sciences, a more or less scientific discipline that combines aspects of philosophy with subjects like artificial intelligence and linguistics. Although neuroscience is in this grouping, the models relating to it are not biologically compatible.

    I'd rather see Max Tegmark's speculations mentioned. When you throw philosophy in with traditional science the primary question is one of competence: Does philosophy of science require a considerable depth of knowledge in that scientific discipline?

    1. No calculation ever would exceed that numberAgent Smith

    Sure, just fix whatever large number you wish and round off to that number. But you might make a mess of computations that follow. In physics renormalizations work in various settings.

    Today, the point of view has shifted: on the basis of the breakthrough renormalization group insights of Nikolay Bogolyubov and Kenneth Wilson, the focus is on variation of physical quantities across contiguous scales, while distant scales are related to each other through "effective" descriptions. All scales are linked in a broadly systematic way, and the actual physics pertinent to each is extracted with the suitable specific computational techniques appropriate for each. Wilson clarified which variables of a system are crucial and which are redundant.

  • What happened before the Big Bang?
    Just as mathematics is the language of the quantum world, it's probably the language of any sort of world beyond the Big Bang, or the ends of time, and it's a language that evolves.

    The obvious one, quantum mechanics. Predictions are highly if not entirely mathematical, many stemming from Schrödinger's equation, given here in stripped down form to demonstrate how it's solutions are wavelike (phasor). This concerns "particles" that are not little bowing balls:

  • What happened before the Big Bang?
    Science explains nature (i.e. transformations of phenomena, facts-of-the-matter, states-of-affairs) with testable models and philosophy interprets – describes, infers – the conceptual ramifications (i.e. presuppositions, implications, extrapolations) of science, no?180 Proof

    I would say that rather than explain nature, science develops models, mathematical or otherwise, that predict happenings in nature. Philosophy might attempt to explain phenomena in more day-to-day, less technical ways. Both are most successful if done by scientists, themselves. Carl Sagan, for instance.
