Wittgenstein’s Language Turn: The Challenges of AGI

The difficulty of AGI lies in Wittgenstein’s shift.

Wittgenstein’s manuscript “Philosophical Investigations” (1929-1936): self-deconstructing earlier systems. Key original text:

Wittgenstein himself overturned the “Tractatus Logico-Philosophicus” by abandoning the ideas of a “unique a priori logical form,” dismantling the picture theory, denying atomism, and rejecting the notion of a “single essential language.”

I. Preface of “Philosophical Investigations”: Public Self-Negation

Original text translation:

“Since I resumed my philosophical work sixteen years ago, I have come to realize that there are serious errors in what I wrote in my first book. My thoughts have collided and corrected the old ideas, ultimately forming a new way of thinking.”

(No longer maintaining the ‘unique a priori logic, crystal-clear pure language structure,’ acknowledging that the earlier closed a priori framework is a human fabrication.)

II. Core Deconstruction: Overturning ‘Language = Logical Image of Reality’ (First Axiom of Early Work)

1. Manuscript Fragment (1929 Cambridge Notes)

“I once believed that propositions were like pictures, mimicking the logical structure of facts. This is a huge prejudice. Language is primarily action, response, and communication, not depiction.”

2. “Philosophical Investigations” §114

“The view that ‘propositions are images of reality’ is a narrow perspective trapped in a limited image model.”

Later determined to be: the forced binding of a single model is just one exception among many language games, not a universal rule.

III. Personally Killing the ‘Unique A Priori Logical Form’

1. “Philosophical Review” (1930 Mid-Core Manuscript)

There is no unique, a priori fixed logical scaffolding. What we consider ’logical a priori’ is merely a solidified grammatical habit, a simplified expression model, not the inherent structure of the world.

2. “Philosophical Investigations” §107

Logic seems like a super-order, a crystal-clear a priori order. But we find that everyday language fundamentally lacks such strictly organized a priori structure. A smooth ice surface (pure a priori logic) is frictionless, but also impossible to walk on.

Key points:

• Early: Pursuing ice-surface-like, non-contradictory, pure a priori logical forms.
• Later: Acknowledging that the ground of life is rough, diverse, and contextual.

→ A priori logic is no longer the ‘underlying law of the world + language,’ but merely a local tool model.

IV. Catalyst for Collapse: Self-Overturning ‘Atomic Facts/Basic Propositions Independence Theory’

(Early system’s foundation) Manuscript 1929

My past basic assumption:

All basic propositions are completely independent of each other. This is wrong. Colors, space, sensory properties inherently exclude and limit each other. My old logical building collapsed in the face of the simplest color judgments.

Completing theoretical suicide:

No independent atomic facts → Early truth-function items, logical images, hierarchical nesting all become invalid.

V. Denying ‘Essentialism’, Completely Saying Goodbye to Classical + Early Wittgenstein

“Philosophical Investigations” §65

I abandon the view that language, thought, and the world must have a common essence. There is no unified definition, no unified a priori form, only family resemblances, diverse uses, and different language games.

(Ladder metaphor:

• Early = A universal ladder, usable by everyone, everywhere.
• Later = Countless temporary small ladders, specific to each scene, used up without needing to be preserved, and certainly not deified.)

VI. The Most Profound Self-Reflection: Ultimate Upgrade of the Ladder Theory

Wittgenstein’s Late Notes

Initially, I built a ladder with propositions to help people see the unsayable. But the biggest misconception was that I assumed there must be only one correct way to climb.

People steal the ladder, worship the ladder, cling to the ladder, proving that the ladder itself has become a new shackle.

(Russell and later followers stole the ladder, turning transitional tools into permanent entities.)

VII. Simplified Summary: Early → Late Complete Self-Deconstruction Chain

1. Discovering color exclusion: atomic logic, a priori isomorphism, internal collapse.
2. Real everyday language: completely inconsistent with ‘image theory + strict a priori forms.’
3. Self-reflection: ‘crystal-clear a priori logic’ is an intellectual fiction.
4. Abandoning the unique essence: from a priori form legislation → describing forms of life.
5. Philosophical positioning rewritten: from ‘drawing boundaries with a priori logic’ → ’treating linguistic obsession, breaking all system obsessions.’

VIII. Brief Review: A Mountain is Still a Mountain

1. Early: Language–Logic–World a priori isomorphic, case/fact/thing levels tightly interwoven, a unique map, a priori rules, a unique ladder.

2. Late Self-Deconstruction: This perfect structure is merely a locally extracted model, not a universal a priori law; the world has more than one database, one logical format, one map; a mountain is always a mountain, the map can change, be diverse, or be discarded at any time.
