Full bilingual text and framework available at self-as-an-end.net — Framework reference: self-as-an-end.net/framework.html The final paper of the trilogy. Starting from the emergence of "I" (13DD), it develops Round 4 (freedom: self-awareness → purpose → unilateral Non Dubito → mutual Non Dubito) on psychoanalytic foundations: Id = 12DD prediction system, Ego = 13DD self-awareness, Superego = 14DD structural necessity. Eastern and Western philosophers are structurally positioned (Aristotle/Nietzsche/Zhuangzi/Tang Bohu at 14DD; Laozi/Plato at the 14DD–15DD boundary; Socrates at 15DD; Wang Yangming between 15DD and 16DD; Kant at 16DD), with the key insight that 14DD→16DD is the leap from "I" to "we" — only "we" can touch the thing-in-itself. The thing-in-itself is unconstructible but locatable (its lower bound is the upper limit of 16DD), and has great love for everything below 16DD: the window does not reject; it nurtures. The three papers themselves embody three rounds of Select-Determine-Expand-Solidify, with the final stop being not a choice but a structural necessity. Chinese and English versions included.
