    What does the "absolute accuracy" in regard to experience even mean? Perhaps you are looking for some absolute certainty? It's a fool's errand, a dimwit's folly. See if you can dig your pointless hole even deeper; should be fun to watch. :rofl:Janus
    Well, whenever you return here, all you ever keep shouting is that whatever you read is fool and dimwit. How could anyone help you? :lol:

    As with most sources, whether Fox or CNN, whether the BBC or Talk TV, one has to make a personal judgement as to whether the source makes a logical and reasoned case.RussellA
    Any popular media based information will be flatly rejected as propaganda in all philosophical discussions unless proved and verified otherwise. :)

    From the Wikipedia article on Transcendental arguments, which presumably uses transcendental logic, Kant used transcendental arguments to show that sensory experiences would not be possible if we did not impose their spatial and temporal forms on themRussellA
    When you say, we impose space and temporal forms on the sensory experiences, it does imply we can also choose not to impose as well. So what happens if we choose not to impose? How do we decide to impose or not to impose?
    I am going to tackle your points one by one taking time (no rush) in order to avoid any confusions.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Of course. There should be as many interpretations as there are folks that bother with it. What he wanted the interpretation to be, should be singular, no matter how many folks bother. Which was the whole point of grounding the theory in logic, insofar as if these premises are the case, then that conclusion follows necessarily. One can, then, grant the conclusions given those premises on the one hand, yet refute the logic by denying those premises ever were the case on the other. In which case, Kant hasn’t been refuted, he’s been replaced.Mww

    I read the scientists conducting the remote experiments on time and space in different locations on the earth based on TI of CPR. It wouldn't be imaginable if one insisted to stay in 1781 and inside the fence of CPR word by word for interpreting and understanding Kant.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Take it or leave it, but first, understand it.Mww

    There must be more than just one way to interpret Kant, because it is now 2023, not 1781. Tendency of denying the objectivity on the obvious points can induce the debilitating melancholy and misunderstanding. :nerd:

    I suppose the other thing is, in what scenario are we not sensible of the world in one way or another? A deprivation tank still provides a temperature etc... It's just aligned so closely with homeostasis its hard to tell. It hasn't actually removed stimuli entirely.AmadeusD

    If we define the world as the totality of the whole universe, then what we have been seeing was tiny particle amount of the world. In that scenario, are we qualified even to say we have been perceiving the world at all? This is just one scenario.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    To record, reason and apply logic presupposes the capacity for it. To come to judgement presupposes there is that which is possible to come to.Mww
    Under that system, one would be very prone to fall into prejudice and illusions instead of knowledge.

    Undoubtedly, but irrelevant.
    (Glances up at thread title)
    Mww
    There would be little point staring at the thread title all day long, if one cannot extend Kant's works into the present time of consciousness and reality.

    Compared to what….2023? Wonder what the views will be in 2123. Oh so easy to look backwards, innit?Mww
    Past is only significant in the perspective of NOW. Future is the same. We only have NOW. We can only look at anything from NOW. If you think you can be in 1781 in reality, then you are in deep illusion. :)
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Oh dear. The entire human intellectual system is presupposed. Do you have any idea at all, just how far it is in the procedural methodology, between reading the statement and the installation of the analytic content of it??????Mww
    Nothing is presupposed in nature and human intellect. That is why we need observation, reasoning and logic in coming to knowledge. When you see the data or content, you record, reason and apply logic to come to judgements.

    According to Kant, the most basic operation of logic “treats of the form of the understanding only”. How is your example anything like that?Mww
    That is just one side of logic, which is the traditional logic. You have a sea of different school of Logic doing things differently for different subjects, which you seem to have no idea of. Even just after Kant, Bolzano has his own theories in Science and Logic, and many other Neo-Kantian and Anti-Kantian philosophers came up with their own views and systems on Logic.

    When he says stuff like, “further than this logic cannot go”, he’s just warning the po’ fools trying to misuse it, but not that the misuse is the fault of logic.Mww
    Kant had very limited views and knowledge on Logic.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    An aberration of the whole point. You’re giving an example from understanding’s point of view, which presupposes the logic.Mww
    Until one reads the statement with the analytic content in full, nothing is presupposed. The statement can be anything until it ends with ".".

    I’m denying the content of logic in its operation, which is true, I can still affirm the necessity of content for its proofs. Examples merely suffice to demonstrate the validity of a logical condition, but do nothing to establish what that condition is.Mww
    Even after the clear example of the most basic operation of Logic from the content of a concept, if you still keep denying it, then it seems you are denying not knowing what you are denying.

    Or did he have a low opinion of the typical employment of it, in which manifests the “mere prating”?Mww
    It is a well known fact from the numerous commentaries on Kant.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Now it may be taken as a safe and useful warning, that general logic, considered as an organon, must always be a logic of illusion, that is, be dialectical, for, as it teaches us nothing whatever respecting the content of our cognitions, but merely the formal conditions of their accordance with the understanding, which do not relate to and are quite indifferent in respect of objects, any attempt to employ it as an instrument (organon) in order to extend and enlarge the range of our knowledge must end in mere prating; any one being able to maintain or oppose, with some appearance of truth, any single assertion whatever. Such instruction is quite unbecoming the dignity of philosophy….”Mww

    Kant had low opinion on Logic, and his view on Logic is abnormally and impractically narrow.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    if we look at an example….
    — Corvus

    A mistake at the expense of, or in spite of, the quotations.
    Mww

    Was giving an example from general Logic point of view (not related to the quotes).
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Yep, he does, at least empirical content. If one wishes to insist the content of logic is its own laws or principles for its operation, he has misdirected it, insofar as the laws of logic apply to the operation of the understanding, such that the application of its own laws to itself, is absurd.Mww

    But if we look at an example, any analytic concept such as a bachelor, it has definition and logic all in the concept i.e. a bachelor is an unmarried man. If you didn't have the concept as a content in a statement, logic won't work. Will it?

    If you say, that you know a bachelor who has remarried recently, you know instantly you uttered a logical nonsense. Without the content "bachelor", how would you have come to the conclusion, the statement was illogical?
  • Anyone care to read Kant's "Critique of Pure Reason"?
    However, according to the Wikipedia article on Logic, logic only deals with the form of an argument and not the content of an argument:
    Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or logical truths. It studies how conclusions follow from premises due to the structure of arguments alone, independent of their topic and content.
    RussellA
    I don't subscribe to the most of Wiki info. In the past any tom dick and harry used to go to Wiki and populate the contents with whatever contents they like. Not sure this is still the case.

    From the traditional logic perspective, they insist that contents is not dealt by logic. Fair enough on that. But from all the other logic, content itself is important part of logic. If you read Bolzano's Theory of Science, you would agree.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    These secondary sources point at a distinction between the importance of the form of a logical statement in traditional logic and the importance of the content of a logical statement in transcendental logic

    Perhaps this means that a logical stalemate is as much dependent on its content as its form
    RussellA
    Great point. :up:
    In the past I have been stating this point to @Janus and @Mww in some previous threads. They sounded to have read somewhere about the traditional logic, and think that it is the only form of logic in existence. They have been opposing on the view that Logic can require contents for its operation. :roll: One can feel pointless trying to argue with the narrow perspectives.
  • Reason for believing in the existence of the world
    The only thing I have ever known myself to exist on/in, is the world. It would be far more unlikely that at times i'm not perceiving it (unconscious ,whatever..) it has disappeared, than it would be that I am simply not perceiving it because my senses are not trained it.AmadeusD
    To immaterial idealists, the world is just perception. When they are not perceiving the world, they don't believe it exists. But to the realists, they tend to believe the world keep exists even when they don't perceive it. Beliefs are psychological state. You either believe something or not with or without reasons. But are there beliefs that need rational justification? Or do we tend to believe in something due to our nature as Hume wrote?

    I suppose the other thing is, in what scenario are we not sensible of the world in one way or another? A deprivation tank still provides a temperature etc... It's just aligned so closely with homeostasis its hard to tell. It hasn't actually removed stimuli entirely.AmadeusD
    I suppose it depends on the definition of the world as well. Yes, the definition of the world, the concept of existence, and the nature of belief.
  • Reason for believing in the existence of the world
    Why would you believe something for which you believe you have justification for believing? Sounds like the definition of stupidity to me.Janus
    To a stupid, everything sounds and looks like stupid.

    Everything I experience gives me reason to believe the world does not depend on my perception of it. Perhaps you believe it doesn't give you such reason; if so, I can only conclude that you are a fool.Janus
    You don't seem to have understood the question. Do you believe in absolute accuracy on everything you experience?

    Why? Under what ground?

    What could certain physiology mean?

  • Anyone care to read Kant's "Critique of Pure Reason"?
    Knowledge given from the objective sciences is empirical, it informs as to experiences of the world; it is the way in which the knowledge is acquired, the systemic methodology for the development of principles and judgements, better known as logic, the intellect uses to acquire it, that is pure a priori.Mww
    Kant thought that just empirical knowledge for the objective sciences were not enough to be the source of infallible knowledge. The A priori elements are needed for the science to be able to have grounds for the rigorous system of knowledge.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    “….. Mathematics and physics are the two theoretical sciences which have to determine their objects à priori. The former is purely à priori, the latter is partially so, but is also dependent on other sources of cognition….”

    Partially so means impure; other sources means from out in the world, or, experience.
    Mww
    We were quoting the same verse. I am not sure "impure" would be the right term. He has given out the official term for it i.e. "synthetic a priori" knowledge.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    It is nothing to do with pure or impure….
    — Corvus

    ….yet he states, clear as the nose on your face…..impure. How can it have nothing to do with exactly what he’s saying?
    Mww
    This is where Kant seems to be showing his inconsistency in CPR. If you think about it, you only observe the objects and the changed objects in empirical reality through time via your sense. There is no such a thing as "change" in the empirical reality. The concept 'change' comes from your mind via a priori intuition. It is nothing to do with the way reason works, but it is how we acquire a priori synthetic knowledge in TI.

    Math is purely a priori because it constructs its own objects; physics is a posteriori because its objects are or can be given to it from an external source, re: the world.Mww
    Some physics knowledge is definitely both a priori and a posteriori, hence synthetic a priori.
    " Mathematics and Physics are the two theoretical sciences which have to determine their objects a priori, the later is partially so, but is also dependent on other sources of cognition." - Preface 2nd Edition CPR, Meiklejohn.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Yes, but a priori is not necessarily pure:Mww
    Kant mainly uses a priori to mean pure in CPR.

    “…. “Every change has a cause,” is a proposition à priori, but impure, because change is a conception which can only be derived from experience….”Mww
    It has nothing to do with pure or impure. It is a priori synthetic proposition.

    A priori carries the implication of universality and necessity; pure/impure carries the implication of the contingency of experience.Mww
    Not sure if pure / impure has much to do with experience. If it does, it would be minor context.

    Kant wants it understood that by a priori, he means without regard to any experience or possible experience whatsoever. He just released himself from having to qualify the term with “pure” every time he used it, the word in the book’s title sufficing as the ground of the whole, the justification for the ground given early on in the text itself.Mww
    But please bear in mind that Kant thought some knowledge is both a priori and also a posteriori e.g. Physics.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    What does “pure” mean; what does “a priori” mean;Mww
    Pure in CPR means "a priori".

    To think space empirically is not to think it as being real, but merely to think of it as that which contains the real, in order for the relations of things becomes comprehensible.Mww
    A tree is standing in the space and on the ground. For you to perceive the tree, the physical space must allow the particles of the light which reflected from the tree, to enter to your eyes. Without the physical space, the light won't be able to travel from the tree to your eyes making all visual perception impossible. So physical space in empirical reality has to be real existence.

    If the representation has no meaning whatsoever, to then talk of its empirical reality, is sheer nonsense. That Kant uses that wording, indicates he means something else by it.Mww
    When empirical reality caused the representation to happen in the mind, but if the mind thinks it is sheer nonsense, then it is a problem of the mind.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    very few of us have had the time to read the almost 800 pages,RussellA
    JMD Meiklejohn version CPR is only 500 pages long (the 2nd edition only). All the other versions are 700 - 800 pages because they combined the 1st and 2nd Editions into one book.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Almost, yes. He is talking about space as an intuited a priori representation, in order to remove it from the necessity of being a phenomenon.Mww
    Yes, that was my point all the way along. Glad to see some sort of agreement. Well almost.
  • Reason for believing in the existence of the world
    We're sometimes wrong about things; what, then, made us wrong, but whatever is indeed the case?jorndoe
    Hence, we try to seek justification on our beliefs and perception.
    But point here is, can belief be justified properly? Belief is a psychological state, which cannot be justified rationally in nature.

    Or are some beliefs also epistemic when justified? But if it cannot be justified, then it can't be. How do we justify our beliefs rationally?
  • Reason for believing in the existence of the world
    If one does not believe an external world exists, then one is a solipsist, right?jorndoe
    But when one believes in the existence of the world, but says there is no justified belief in the world when not perceiving it. What would you class the position?
  • Anyone care to read Kant's "Critique of Pure Reason"?
    More than irrelevant; incomprehensible. Vision needs that which appears, space does not appear, space cannot be a sensation, space cannot be real.Mww
    If you accept, space is invisible emptiness which contains all the objects in universe, then you are seeing it, when you don't. Sense perceives invisible objects.

    It can be said, however, space can be real in a different way than that which appears. Which is an entirely different philosophy on the one hand, and a separate science on the other.Mww
    Kant is not talking about the space in empirical reality in CPR, but he seems mentioning its legitimacy in various places from presupposition. He is talking about space as intuited concept in TI to explain how Geometry and visualisation works. And whatever you are perceiving, they originate from the external objects.

    Nevertheless, whichever it is, reason is absolutely necessary for whatever the conclusions might be.Mww
    Yes, hence his CPR.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Maybe, dunno, but we’re not doing physics. We’re doing transcendental philosophy.

    I don’t recall saying or implying that seeing was a property of space. Or anything, for that matter.
    Mww

    Then, the question,
    You can see the body, but can you see the space?Mww
    is irrelevant in Transcendental philosophy?
  • Anyone care to read Kant's "Critique of Pure Reason"?
    You can see the body, but can you see the space?Mww
    Seeing is not a property for space. Space has a few properties based on physics, but visibility is not one of them.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    As a thing-in-itself it cannot be talked about (like the Fight Club)RussellA

    A resolute agreement :up:
  • Anyone care to read Kant's "Critique of Pure Reason"?
    As you say, Kant wanted to combine the two schools of rationalism and empiricism.RussellA
    :up:

    However, not to show that Metaphysics is superior to the Natural sciences, but rather better explain both Metaphysics and the Natural Sciences. Neither Metaphysics nor the Natural Sciences could be properly understand without first amalgamating both rationalism and empiricism.RussellA
    In the preface CPR, Kant sounds like he is on duty to reinstate Metaphysics as the queen of all Science.

    Kant's synthetic a priori amalgamating transcendental idealism and empirical realism is necessary to better understand both Metaphysics and the Natural Sciences. He was a dualist.RussellA
    Kant's Space in TI of CPR is intuited pure concepts, and he is talking about how Metaphysics works. He is not talking about the space in empirical reality in CPR (it is presupposed existence). They are totally different things all together. If Kant denied the existence of the physical space in empirical reality, he would commit himself to an immaterial idealist like Berkeley. I don't see Kant would have done that at all. As you indicated, I agree, Kant was a dualist.
  • Anyone care to read Kant's "Critique of Pure Reason"?


    Yup, I read that Kant has been taken seriously by the current scientists especially, because his idea on Space and Time is not just for empirical reality, but also for pure intuitions. This perspective of space and time warrants for more rigorous perception of the reality.

    Scientists have been trying to find rationally justified warrant for infallible validity from their observations, theories, knowledge and claims on the reality out there, and they believe Kant's TI has it due to its dualism.

    Observations on objects in the space of empirical reality alone has possibility of illusions. They want further verifications on their data by the pure space a priori intuitions, concepts and reasoning.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Despite the direct textual references refuting that opinion, you both continue the misunderstanding. Or I do. One or the other.Mww
    If Kant's view on space and time was only pure intuitions, and there is no physical space and time as such, then he wouldn't have been taken seriously by the current philosophy or science. :)

    If space and time are empirical realities they absolutely cannot be pure a priori conditions residing in the constitution of the subject, and if such were the case, that they are empirical realities, Kant could not justify them as antecedent conditions for anything of pure a priori content.Mww
    Kant was a dualist. Space and time was physical existence in empirical reality as well as pure intuitions for metaphysical knowledge. He had been only focusing on the latter in CPR.
  • Anyone care to read Kant's "Critique of Pure Reason"?
    Kant was trying to save rationalism from Hume's sceptical challenges particularly wrt causation.unenlightened
    Did he not oppose to both rationalism and empiricism? He wanted to combine the two schools, saying that both rationalism and empiricism lack in coherence in their perspective. He then set up his own system amalgamating the two, and proved Metaphysics has more legitimacy than Natural Science, because metaphysical knowledge is based a priori categories and pure intuitions.
