3. ‡EvaWiki, “Nebuchadnezzar's Key”, http://wiki.evageeks.org/Nebuchadnezzar's_Key
4. Nebuchadnezzar's Key -> Signifiant ‡TBS Radio Life, 「『ヱヴァンゲリヲン新劇場版・破』公開記念　深夜の緊急鼎談」 , http://www.tbsradio.jp/life/2009/06/post_119.html https://youtu.be/DAMWnknrypg?t=4m14s
5. Signifié et Signifiant ‡Ferdinand de Saussure, “Un signe linguistique est l'union arbitraire et conventionnelle d'un signifiant et d'un signifié”, http://www.ac-grenoble.fr/PhiloSophie/logphil/notions/langage/convers/textes/saussure/signe.htm ‡Wikipedia, “Signifié et signifiant”, https://fr.wikipedia.org/wiki/Signifi%C3%A9_et_signifiant le signifié le signifiant “cheval” signifie signifiant “Nebuchadnezzar's key”
6. The Babylonian Confusion ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. p.25. New York: Cambridge University Press, 2010. Print. 対象 object representamen 表意体 interpretant 解釈項 シニフィエ signifie signifiant シニフィアン “Nebuchadnezzar's key” Dyadic ( 二元論 ) Triadic ( 三元論 )
7. Dyadic and Triadic ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. pp.27-28. New York: Cambridge University Press, 2010. Print. What Dyadic model ( 二元論 ) Triadic model ( 三元論 ) Who Augstine, Saussure Plato, Aristotle, Peirce When 4th centry 5th centry BC Where Algeria, Switzerland Greece, US Why ? ? How signifian -> signifie representamen -> intepretant -> object
8. Dyadic and Triadic - FP vs OOP • Dyadic and Triadic • 5th centry BC : Triadic • 4th centry : Dyadic • Modern : Dyadic and Triadic • FP vs OOP • 1958 : FP (LISP) • 1967 : OOP (Simula) • Moden : FP vs OOP ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. pp.27-28. New York: Cambridge University Press, 2010. Print. ‡Wikipedia, “Functional programming history”, https://en.wikipedia.org/wiki/Functional_programming#History ‡Wikipedia, “Object-oriented programming history”, https://en.wikipedia.org/wiki/Object-oriented_programming#History ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. pp.27-28. New York: Cambridge University Press, 2010. Print.
9. FP -> Haskell data Key = NebuchadnezzarKey String use(NebuchadnezzarKey door) = "open the door to "++door main = let key = NebuchadnezzarKey "Human Instrumentality" in putStr(show (use key)) ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. p.12. New York: Cambridge University Press, 2010. Print.
10. OOP -> Java ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. p.14. New York: Cambridge University Press, 2010. Print. class Key { String door; Key(String door) { this.door = door; } public String use() { return "open the door to " + door; } } class NebuchadnezzarKey extends Key { NebuchadnezzarKey(String door) { super(door); } } void run() { NebuchadnezzarKey key = new NebuchadnezzarKey("Human Instrumentality"); System.out.println(key.use()); }
11. Haskell -> Dyadic data Key = NebuchadnezzarKey String use(NebuchadnezzarKey door) = "open the door to "++door signifie signifiant NebuchadnezzarKey use door
12. Java -> Triadic class Key { String door; Key(String door) { this.door = door; } public String use() { return "open the door to " + door; } } class NebuchadnezzarKey extends Key { NebuchadnezzarKey(String door) { super(door); } } object representamen interpretant NebuchadnezzarKey door use
13. Dyadic and Triadic ⇔ FP vs OOP signifie signifiant NebuchadnezzarKey use door object representamen interpretant NebuchadnezzarKey door use ‡Tanaka-Ishii, Kumiko. Semiotics Of Programming. pp.38-39. New York: Cambridge University Press, 2010. Print.
