    "Inference or proof is parasitic; it requires knowledge by other means which it can then use to extend what is known."Sam26

    It is interesting how your friend, Dr. Bitar correlates inference and proof with “parasitic”. I see his metaphor. Exactly as it is, inference, proof, knowledge, etc... extend themselves as parasites to what is known.
    I guess we can see the parasitic example in a positive side! Faraway from pandemics or illnesses!

  • Aristotelian logic: why do “first principles” not need to be proven?
    I like to think of a community trying to rationally settle what they ought to believe.Pie

    Well yes, it is a good way to watch this topic. I think most of the philosophers since Aristotle era tried to debate or explain the big problem of logic. Because we the humans, as rational beings, tend to go further than simplistic emotions. But There can be a problem: the infinite doubt of our possibilities. This is why I personally think Aristotle was a very clever thinker because he proposed that there are, at least, basic patterns that are true just for basic rationalism. I have tried (wrongly) search what these principia primae are about because I was so lost when I published the OP yesterday.
    Nevertheless, the answers from the other mates are pretty drafted and they help me to get a more clear interpretation.

    They'll just generally establish more complex and doubtful claims by working from those that are less so,Pie

    Interesting because I have felt the same thought too. But I think this issue is morbe related to philosophy of language. The limits of understanding all the philosophical doctrines about logic depends on the art of language too. When I read Gödel or Kant it makes me feel a very complex situation because they express themselves in their works with a very complex language.

    What makes an observation true or false will be helpful!
    I just read it and I find the following lines so interesting:

    This quote from @Banno is very helpful to keep going further forward on this topic!

    "Photosynthesis is what takes place in plants" is true only if photosynthesis is what takes place in plants.

    And generally, "P" (note the quote marks) will be true only if P. This is called a T-sentence. T-statements set out the general form of all true sentences. Although T-sentences appear uninformative, they make a few things clear. For example, for "P" to be true nothing further is needed than that P. Including being observed.

    In logical form,

    "P" is true IFF P

    That is, "Photosynthesis is what takes place in plants" will be true regardless of whether or not it is observed to be true.

    This is one of the most humanistic acts or “virtues” we have inherited in ourselves. Interesting, doesn’t it? The desire of searching for complex answers that are unable to know. This is why philosophy is based on tricky questions.
    For example: why the “first principles” do not need to be proven? Is very complex itself. So I guess this is the trick of the OP: there is not necessary to answer, but at the same time we want to “know” about because we sapiens sapiens love to go further of basic explanations and thoughts! :eyes:

    "Aristotle's first principles" work ... until they don't, just like other "first principles" in domains other than logic (vide S. Haack's foundherentism as critique and alternative to foundationalism of "first principles").180 Proof

    Thanks for sharing, 180! :up:

    That's true it can happen a scenario where Aristotle's "first principles" don't work. In this context, the paper I read yesterday, shows diverse solutions according to different philosophers., for example: The Rationalists, such as Descartes, Spinoza, and Leibniz: Self-evidence breaks down as a solution to the Problem of First Principles because there is no way to resolve disputes about whether something is self-evident or not.
    Hume sharpened the Problem of Induction by noting that no generalizations whatsoever are logically justified. The Empiricist tradition thus culminated in Skepticism, Hume's conclusion that knowledge in the traditional sense does not exist.
    Finally, Karl Popper resolves the regress of reasons, at least for scientific method, by substituting falsification for verification

    So, who do you trust : Aristotle or Augustine? :joke:Gnomon

    Aristotle! I trust whatever comes from logic and metaphysics not from faith! But I respect every point of view and beliefs. Everyone is free to trust more one than the other!
  • Aristotelian logic: why do “first principles” not need to be proven?
    What I tried to say is that I interpret Aristotle's logic is based on basic principles or "principia primia". Thus, axioms so logical and basic that do not need to be proven. Then, they are universal affirmative premises which help us to elaborate syllogisms and thus, logic itself. As we put some examples previously such as "substance" and "essence" that these are necessary true.

    God thinking the universe and himself into existence is the unmoved mover, and would seem to count, right? But that's not exactly a universal affirmation, ala the logic.Moliere

    Yes, I see your point. I am agree.

    It's a metaphysical proposition about the nature of reality and how everything relates back to something fundamental that predicates it all.Moliere

    Exactly. This is what I was looking for. I mean, what we should consider as "fundamental" which predicates it all?
  • Aristotelian logic: why do “first principles” not need to be proven?
    All contraries, then, are always predicable of a subject, and none can exist apart, but just as appearances suggest that there is nothing contrary to substance, argument confirms this. No contrary, then, is the first principle of all things in the full sense; the first principle is something different. — Aristotle, Metaphysics XIV

    :fire:

    The specific quote I am looking for! Fantastic. This explains everything. Aristotle brought a very important axiom to develop logic.
  • Aristotelian logic: why do “first principles” not need to be proven?
    . I did, however, check the physics and the prior analytics for "first principles" as well, just out of curiosity, and didn't find as much that seemed to grab me as relevant.Moliere

    No worries! It is a very opened and beautiful debate because "first principles" is a very general term and it leads us to wonder what does really means when we try to specify it. So, I even thinks it can take hours this debate.
    Aristotle was a clever man when he wrote about these fundamental principles because after centuries we still debating.

    And the last time I read Aristotle in real depth was over 10 years ago.Moliere

    In my case, it was over 4 years and was Nichomachean Ethics! It brings me back good memories :100:
  • Aristotelian logic: why do “first principles” not need to be proven?
    I'm just pulling quotes from The Metaphysics which mention first principles and first philosophy, because that's what I thought was referred to be Aristotle as "the first principles"Moliere

    Completely agree and you are, of course, on the right path because the paper I have read was referring and quoting to The Metaphysics. So, I appreciated all the big quotes you shared with us. The paper I used is not that complete and drafted.

    then I think it'd be fair to say it was be a Subject, and not a Predicate.Moliere

    :100: :up:

    They seem to be at the top of the species-genus chain, and somehow explain how everything is made of or comes from some primary thing,Moliere

    This is why, I guess, we can treat it as universal affirmative premises inside Aristotle's syllogisms. Or as @Gnomon previously said: The only evidence to support such unproven premises (axioms) is logical consistency.
  • Aristotelian logic: why do “first principles” not need to be proven?
    It is not something worked out by reason (dianoia) but something the intellect (nous) sees.Fooloso4

    :up: I see and understand yout point and argument. But I think I have made a mistake because I didn't quote all the phrase you were referring to. The quote ends in this way: (and I think it probably fits in your arguments and point of view)

    But there is no certainty to the generalizations of induction. The "Problem of Induction" is the question How we know when we have examined enough individual cases to make an inductive generalization. Usually we can't know.

    Then, I think here is when (nous) appears. Probably we can know thanks to how the intellect sees.
  • Aristotelian logic: why do “first principles” not need to be proven?
    First of all, thank you for taking part in my thread. Appreciated it.

    First Principles are simply labels for First Causes : the cornerstone of all practical knowledge. Example : the distinction between Substance (matter) and Essence (form ; qualities).Gnomon

    I understand it now! Both labels have always been a classical debate among all philosophical schools or doctrines.
    I think is important to bring here some thoughts of John Locke -as an example- about "primary" and "secondary" qualities:
    These I call original or primary Qualities of Body, which I think we may observe to produce simple Ideas in us, viz. Solidity, Extension, Figure, Motion, or Rest, and Number. Such Qualities, which in truth are nothing in the Objects themselves, but Powers to produce various Sensations in us by their primary Qualities, i.e. by the Bulk, Figure, Texture, and Motion of their insensible parts, as Colours, Sounds, Tasts, etc. These I call secondary Qualities. [An Essay Concerning Human Understanding, Book II, Chapter VIII]

    Apparently, Aristotle's First Principles were presumed "self-evident", based on his self-confidence in his own reasoning ability. But quantum scientists are no longer so self-assured, regarding their ability to make sense of the evidenceGnomon

    That's true.

    Nevertheless, I think Aristotle's principles of logic are still important in some ways. After thousands of years the system of reasoning by syllogisms can help us. I understand that is a very basic pattern if we compare it with the complexity we currently live in. But the "essence" :grin: keeps flourishing!

    No. Faith requires the belief in something that actually exists or at least exists in your thoughts.

    I am agree with @180 Proof and I also think the OP is contradictory. There is not "atheistic faith" because atheism is against this sacred and religious act. Putting "faith" and "atheist" in the same group has no sense

    And what I envied most about him was that he managed to reach the end of his life without the slightest conscience of being burdened with a special individuality or sense of individual mission like mine. This sense of individuality robbed my life of its symbolism, that is to say, or its power to serve, like Tsurukawa’s, as a metaphor for something outside itself; accordingly it deprived me of the feelings of life’s extensity and solidarity, and it became the source of that sense of solitude which pursued me indefinitely. It was strange. I did not even have any feeling of solidarity with nothingness.

    “The Language Instinct” by Stephen Pinker.T Clark

    It is a very substantive and drafted OP. I have been thinking and I guess the following paper can be attached to your arguments about the complexity of thinking. Language is one of the main examples indeed.
    Probably you already know it but there is a book called How to do Things with Words by John Langshaw Austin. Well, he also wrote a philosophical paper called Sense and Sensibilia.
    According to his thoughts in those papers he wrote:

    Austin argues that [Ayer] fails to understand the proper function of such words as "illusion", "delusion", "hallucination", "looks", "appears" and "seems", and uses them instead in a "special way...invented by philosophers." According to Austin, normally these words allow us to express reservations about our commitment to the truth of what we are saying, and that the introduction of sense-data adds nothing to our understanding of or ability to talk about what we see.

    Again, Austin argues in Other Minds:

    He [Austin] claims, is that if I say that I know X and later find out that X is false, I did not know it. Austin believes that this is not consistent with the way we actually use language. He claims that if I was in a position where I would normally say that I know X, if X should turn out to be false, I would be speechless rather than self-corrective. He gives an argument that this is so by suggesting that believing is to knowing as intending is to promising— knowing and promising are the speech-act versions of believing and intending respectively.

    I wish these brief quotes can be useful and interesting for you. Glad to see an OP from you again.

    There are two different sources of law:

    1. Positive law: those laws which are approved and promote by the Congress and Senate thanks to the representation of the people in the chambers.
    2. Natural law: basic principles which are inherited in the rule of law in each nation such as "good faith", "moral", "equity" etc... these concepts are not necessarily being expressed in the law itself but they are inside them. It is like their "soul"

    We can say that Natural law comes from equity or "equilibrium". Whenever you want to approve a law you tend to reach equal footing.
  • On beautiful and sublime.


    "Golden" as a characteristic has a deep connection to exclusivity and richness. Nevertheless, Mishima's point of view in his book "The temple of Golden Pavilion" gives another perspective. Their beauty is related to the "sublime" that is even scary for the protagonist (Hayashi Yoken).
    [...]Throughout his childhood he is assured by his father that the Golden Pavilion is the most beautiful building in the world, and the idea of the temple becomes a fixture in his imagination.
    [...]Mizoguchi tells her about his experiences. She tries to seduce him, but he experiences visions of the temple.

    The 'Kinkakuji' is an assemblage of extremely beautiful sentences, and the whole work is filled with an artistic beauty and transiency that holds Kinkaku-ji Temple at its center. Although the Kinkaku-ji Temple itself was a human work, the behavior and feelings of mankind before it were full of sordidness and weakness. However, perhaps transience alone was one thing both did have in common.
  • The US Labor Movement (General Topic)
    I'm not a leftist, but the small impact that trade unions have in the US simply will widen the gap between the rich and the poor and hinder the ability for a larger middle class to grow.ssu

    That's true.

    To be honest, I even think that trade unions (as we know it in Europe) do not exist in the USA at all. Probably, this is due to "Truman doctrine" which wanted to erase all "communist" or socialist theories. According to this thesis, trade unions are not allowed in the USA because it is "contrary" to capitalism itself. So, they eradicate all possible interference between a worker with his businessman. It is weird but it looks like they have the thought that "you are poor because you deserve it" and the "businessman doesn't have to pay with his taxes your medicines". They implemented the savage capitalism.

    I am agree with you that in Europe, the trade unions had a more impact. All the progress in terms of healthcare system, public education, or the regulation of working hours came thanks to them.
    But all of these efforts, have come, from a socialist thesis indeed. It has always been a fight between the businessman against the workers.

    Another example: we are currently having a debate in Spain about to increase the minimum income to 1.000 €. The businessmen obviously do not want to but the trade unions are fighting to reach this aim.
    I see it as the classical gap between the rich and the poor. The powerful and the servant. Socialism vs conservatives or "traditionalists"
  • The US Labor Movement (General Topic)
    The worst faulty idea about trade unions is that they are a socialist endeavour promoting socialism.

    They aren't, actually. They are just a common sense way to deal with your employer.
    ssu

    I think it depends on the country we are talking about. Here in Spain trade unions are literally a way to promote socialism (or classwork-leftist doctrines) against the entrepreneur or employers.
    I am agree with you that it is a group which -supposedly- has the aim to deal with the employer. But this is a leftist position indeed.
    For example: in my country there are three key actors who debate about employee's income: government, CEOE (representatives of entrepreneurs) and UGT (Trade unions)
    Wherever they debate is so clear that trade unions promote: worker rights vs rich privileges; better salaries; less working hours or gender equality, etc...
    These concepts are socialist or at least "social-democrat" doctrine.

    Well you can see it yourself in this image. Look the symbols. Trade unions are a promotion for socialism.
