# The Critique of Finitude: Exploring the Limitations of John Searle’s Chinese Room



**Author: Franklin Silveira Baldo **



## Abstract



This article critically examines John Searle's Chinese Room argument by introducing the concept of finitude. We argue that the thought experiment implicitly assumes an infinite capacity for symbol manipulation, which does not align with the practical limitations of finite systems such as humans and machines. By exploring how finitude affects the argument, we offer new insights into the nature of understanding and its implications for artificial intelligence.

## Introduction



### 1.1 Overview of the Chinese Room Experiment



John Searle, a prominent philosopher in the philosophy of mind, introduced the Chinese Room thought experiment to challenge the notion of "strong AI"—the idea that a computer running the right program can possess a mind and consciousness equivalent to a human's. In the experiment:



- A person who does not understand Chinese is locked in a room.

- They receive Chinese characters through an input slot.

- Using an extensive rulebook written in their native language, they manipulate symbols to produce appropriate responses in Chinese.

- To an external observer, it appears as if the person understands Chinese, but internally, they are merely following syntactic rules without any comprehension.



### 1.2 Relevance and Impact on the Philosophy of Mind and AI



The Chinese Room has become a central argument against the possibility of machines possessing genuine understanding or consciousness. Its influence extends to debates about:



- The distinction between syntax (symbol manipulation) and semantics (meaning).

- The nature of understanding, intentionality, and consciousness.

- The development of artificial intelligence and cognitive science theories.



### 1.3 Purpose of the Article: Critically Examining the Assumption of Infinitude in the Chinese Room



This article proposes that the Chinese Room argument implicitly assumes an infinite capacity for symbol manipulation. We argue that when considering the finite nature of real-world systems—both humans and machines—Searle's conclusions may not hold. We aim to explore how the assumption of infinitude affects the argument and its implications for AI understanding.



## The Chinese Room Experiment



### 2.1 Description of the Original Experiment



The Chinese Room thought experiment is set up as follows:



- A monolingual English speaker is inside a room equipped with a rulebook for manipulating Chinese symbols.

- Chinese speakers outside the room send in questions written in Chinese.

- Using the rulebook, the person inside matches input symbols to output symbols without understanding their meaning.

- The responses are coherent to the Chinese speakers outside, who believe they are communicating with someone who understands Chinese.



### 2.2 Searle’s Conclusion on Symbol Manipulation and the Lack of Understanding



Searle concludes that:



- **Syntax vs. Semantics**: Manipulating symbols based on syntax does not lead to an understanding of semantics.

- **Intentionality**: Machines lack intentionality—the capacity of the mind to be directed toward something or about something.

- **Rebuttal to the Systems Reply**: Even if the system as a whole appears to understand Chinese, the person (and by extension, the machine) does not possess genuine understanding.



### 2.3 The Role of Implicit Infinitude in Searle’s Argument



The argument assumes:



- The rulebook must account for every possible input, implying an infinite or exceedingly large set of instructions.

- The person can process any Chinese sentence, regardless of complexity.

- Practical limitations of memory and processing are disregarded.



## The Assumption of Infinitude



### 3.1 How the Experiment Assumes an Infinite Capacity for Symbol Manipulation



For the Chinese Room to function as described:



- The rulebook would need to handle an unbounded number of symbol combinations.

- Creating or using such a rulebook is impractical due to physical and cognitive constraints.

- The thought experiment overlooks the limitations inherent in finite systems.



### 3.2 Comparison to Finite Systems (Both Human and Machines)



In reality:



- Humans have finite memory, limited processing speed, and a limited lifespan.

- Computers and AI systems have hardware limitations and finite storage capacities.

- Advanced AI relies on probabilistic models and cannot account for every possible input explicitly.



### 3.3 Practical Limitations of Finite Systems



Consequences of finitude include:



- Errors and misunderstandings due to limited knowledge or processing capacity.

- Necessity for generalization from limited data, leading to approximations.

- Need for learning mechanisms to handle new or unexpected inputs.



## Finitude and Understanding



### 4.1 Examining How a Finite Room Would Impact the Experiment



Modifying the thought experiment:



- A finite rulebook covers only a subset of possible inputs.

- The person may encounter inputs not covered, leading to communication failures.

- Introduces the need for learning and adaptation within the system.



### 4.2 Would It Be Possible to Manipulate Information Indefinitely in a Finite System?



Analyzing limitations:



- Finite systems cannot process or store infinite information.

- Storage and processing constraints hinder long-term functionality.

- Continuous operation without degradation is unrealistic.



### 4.3 The Relationship Between Limited Resources and the Simulation of Understanding



Finitude influences understanding by:



- Necessitating efficient processing strategies like pattern recognition and inference.

- Encouraging the development of learning algorithms to manage information.

- Suggesting that understanding may emerge from managing information within limitations.



## Comparison with Modern Computational Systems



### 5.1 Limitations of LLMs and Neural Networks in Practice



Current AI technologies:



- Large Language Models (LLMs) like GPT-4 operate under finite computational constraints.

- Use statistical patterns from data to generate responses.

- Face limitations such as biases, inability to handle truly novel inputs, and lack of genuine understanding.



### 5.2 Arguments Supporting That Finite Systems Can Indeed Simulate Understanding



Evidence includes:



- AI systems performing complex tasks requiring apparent
