• Logic is a form of metaphor. - Duality of understanding. - imaginability and symbol manipulability

  • Symbol manipulability is based on imaginability
    • The linguistic aspect of impression is [metaphor
    • Imagination
  • Abstract expressions lead to images through metaphors.
    • "The heart is not full" = likening the heart to a container.
    • He's testing" = time is the container.
      • Metaphor of space : container, direction, movement, existence
      • simile of a simile of a simile of a simile of a simile
    • Example text: Kant's Critique of Pure Reason
      • What corresponds to the senses in a phenomenon, I name the material of the phenomenon.
      • The arrangement of the various contents of a phenomenon in terms of certain relationships is called the form (something takes) of the phenomenon.
    • This "organizing" is not human in subject (it is a form) → pseudo-human metaphor.
  • Logic is a form of metaphor.
    • What is the "form" or "common property" of the container metaphor -> a closed line divides the space into two parts.
      • True or false in formal logic is inside or outside a set, so it corresponds to the logic of containers
    • The form of the simile metaphor is a triad of "subject, object, and action"

• Japanese Logic and English Logic

  • The logic of English is the logic of the subject
    • Both generative and cognitive grammar are subject logic
    • In English, inanimate subjects are common.
  • Is "subject-predicate" universal?
    • Not many subject-mandatory languages
      • English, German, French, Dutch...
      • Countries that strongly influenced the process of Japan's opening to the world
  • The "subject-commentary" relationship
    • The predicate is the central element of the sentence
    • The "carried" is central, and both "who" and "what" are complements and tautologies.
      • Omitted if not required.
  • The basis of Japanese logic is container logic
    • Japanese has many expressions that make people "places".
      • English often compares inanimate objects to people; Japanese often compares people to places.
    • Taro-san has a lot of experience" = "Taro-san has a lot of experience in his container.
    • Spring is at its most beautiful at dawn.
      • Spring is not the dawn of a new year.
      • Akebono is the best in the container called spring, he says.
  • one grammar, two logic
    • I am not claiming that "English is only the logic of the subject, Japanese is only the logic of space."
    • The logic often used is the logic of the subject in English and the logic of space in Japanese.
    • The elephant carried the load" is the subject's logic, and the Japanese can understand this.
    • It's hard to explain "elephants have long noses" using subject logic.
      • The logic of space is that "long nose" is valid in the container of "elephant".
    • Evening has come."
      • The Logic of the Entity from Which Evening Comes
  • Case particles as spatial logic

• The basis of Japanese logic is propositional logic.

  • Propositional logic is of the form [Container Metaphor
    • Correspondence between "is/is not X" and "in/out of container
  • The predicate is of the form [simile of a simile of a simile of a simile
    • A predicate here is not a "predicate" of "subject predicate" but a predicate of "predicate logic

    • For example, if "Socrates" is represented by the term s, and P is the predicate symbol for "is a human being," then P(s) gives a logical formula with the truth "Socrates is a human being."

    • https://www.sist.ac.jp/~kanakubo/research/reasoning_kr/predicate_logic.html

    • This P(s) is the predicate
      • Propositional logic plus predicates is classical logic
    • A do B" is subject-object-action, so subject logic
    • A is B" is a kind of
    • Dutch also has a corresponding expression for is (be verb) (is for third person singular)
    • At the time of the opening of the country, Japan did not have a corresponding expression.
    • Then "is" was coined (Ch. Yanagi, "The history of the formation of translated words") → The history of.
    • A is B" = "In a container called A, B de al."
      • I'm not familiar with the term "container," but it means "B holds in a set that satisfies the condition A."

• Japanese is not illogical and Japanese logic is not unique. The difference from Western languages is the ratio of the use of subject logic and spatial logic.
