  • How To Debate A Post-Modernist
    There is no self-sufficient and uninterpreted use of the formalism of quantum theory that can be of any use in making predictions of empirical observations. — Pierre-Normand

    Why limit your assertion to formalisms and quantum theory?
    Why would your assertion not apply as well to plain prose in a less mathematical endeavor?
    In fact why would it not apply to doing washing machine settings based on what the manual says?

    How would I know, what is your point? — Metaphysician Undercover

    Just to make sure, by "the commutativity of multiplcation"
    I mean 3 times 7 is the same as 7 times 3 - the order doesn't matter.
    Contradicting it means saying there are cases where changing the order
    would result in different numbers.

    I take my leave here.
  • Religious experience has rendered atheism null and void to me
    Not all logical axioms are mathematical axioms. The parallel postulate might be a self-evident truth, and it might be a logical axiom, but it is not mathematical, it is geometrical. Do you recognize the difference between mathematics and geometry? — Metaphysician Undercover

    I asked for an example of a philosophical axiom that is not also a logical or mathematical axiom. Not only do I not see the example, I see the words "logical axiom" and "mathematical axiom" in your response but no mention of philosophical axioms.

    What is the status then of mathematics that replace the parallel postulate with something that contradicts it?

    So you are saying that some conventions are more widely accepted than others. — Metaphysician Undercover

    Are there civilizations that assert statements that contradict the commutativity of multiplcation?

    The words "widely accepted" are not in my comments.

    But my earlier point is, people are often saying this sort of thing, but not citing the apparent purveyors of it. — mcdoodle

    The authors criticized in "Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science" for starters.
  • How To Debate A Post-Modernist

    It's a bit more complicated than that.

    Someone like Rorty would leave science alone but take issue with the philosophy of science.

    He hopes that we will eventually abandon the debates of the philosophy of science for the reasons that we have already done so for the consubstantiation/transubstantiation debate - not because we have settled the issue one way or another but because we have outgrown the question.

    He would agree with Richard Feynman that a scientist needs philosophy as much as a bird needs ornithology.
  • Religious experience has rendered atheism null and void to me
    That is why mathematical axioms must all be verified, they may be false. — Metaphysician Undercover

    Has the parallel postulate (in geometry) been verified? Or is it false?
  • Religious experience has rendered atheism null and void to me
    In philosophy, an axiom is a self-evident truth, and therefore cannot be wrong. — Metaphysician Undercover

    Give an example of a philosophical axiom that is not also a logical or mathematical axiom.
  • Religious experience has rendered atheism null and void to me
    Since the postulate is posited for some purpose, not because it is a self-evident truth, as is the case in philosophy, the postulate may be false. — Metaphysician Undercover

    In the case of geometry, is the parallel postulate false?

  • Religious experience has rendered atheism null and void to me
    ↪Metaphysician Undercover

    In formalisms, there are no assumptions.
    What they have are axioms and postulates.

    Euclidean and non-euclidean geometry are both valid formalisms.
    They differ over one axiom. The versions actually contradict each other. That is why "assumption" is not the word used and "axiom"/"postulate" are used instead.
  • The Free Will Defense is Immoral
    ↪Metaphysician Undercover


    Eventually the rubber hits the road for some assertions. Like for example whether somebody is dead or alive. And then there are assertions of the sort made in mathematics.
    What sort is
    "God created because He knew that it was good to do so"?
  • Religious experience has rendered atheism null and void to me
    ↪Metaphysician Undercover


    In a formalism, the terms don't refer to anything in particular. What is important is how they relate to each other and the rules related to what sentences you can form with them. There is no "articifial" in formalisms. They just need to be consistent. They become interesting when they can be applied, like in this case to geometry. They (complex numbers) are an integral part of quantum mechanics.
  • The Free Will Defense is Immoral
    ↪Metaphysician Undercover


    So, assertions about God are based on conventions.
  • Religious experience has rendered atheism null and void to me

    Look at "Geometric interpretation" in

  • The Free Will Defense is Immoral
    ↪Metaphysician Undercover


    To be clearer, why would your answer be preferable to something like
    "God created because He knew that it was evil to do so."
    In what way would this alternative answer be less guided or constrained by Thorongil's question?
  • How To Debate A Post-Modernist
    The thing is, I'm looking for a deeper conception of the postmodern view of the problem. — BenignParadigm

    The best representative of that side is Rorty. On the plus side he writes as clearly as any analytic philosopher. Other than the other book I mentioned, look at Bouveresse and Rorty's reply in

    It's a pretty silly piece of reasoning, so my advice is to embrace it on behalf of your opponent in order to show them where it leads.

    Good luck finding that opponent outside of the junior leagues.
  • How To Debate A Post-Modernist
    The debate has moved beyond the simple terms that you have described. Have a look at:

    What about "dog"? Or "lifeform"?
  • Religious experience has rendered atheism null and void to me
    ↪Wayfarer
    But Western thinking has honed in on what can be measured quantitatively and reproduced in the public domain as the sole criterion of truth. Which is pretty well the exact definition of 'scientism'.

    How can that be? The greatest honours go to the scientists who overthrow the most established theories. Einstein was not a heretic. Newton was not a dishonoured charlatan. Both are in the pantheon.

    And at least one of those religious orders was of fighting men who trained to kill and did kill.
    As valid or invalid a point as the one you brought up.

    So how should we treat them when used in an argument for or against something that does involve representation.
  • The Free Will Defense is Immoral
    ↪Metaphysician Undercover


    Ignore my question if you are being ironic. But what guides or constrains the answer you give?
  • Religious experience has rendered atheism null and void to me
    ↪Metaphysician Undercover


    This is a problem only if you are essentialist about the mathematics of complex numbers. Or - you could treat it as a consistent formalism and give it a geometric interpretation.
  • Why do we follow superstition?
    ↪TheMadFool


    Modulo essentialism as regards causation.
  • Mathematics & Philosophy
    Arithmetic and geometry
    are the formalisation of
    the most basic intuitions
    we use in out interactions
    with the material world.

    Mathematics in its more
    advanced forms are further
    abstractions and generalisations
    of that initial formalisation.

    When applied to domains where our
    basic intuitions break down
    e.g. relativity and the quantum
    mechanical world, mathematics is
    a tool used to construct
    isomorphisms (loosely speaking)
    betwen said domains and our basic
    intuitions.
