Study Notes
Cantor's Diagonalization
- Cantor's Diagonalization demonstrates that the set of real numbers is not enumerable.
- It works by assuming that all real numbers can be listed, then constructing a new number that differs from each number in the list at some position. This new number is not on the list.
Turing Machines and Computability
- Turing used similar reasoning to show that not all real numbers are computable by a Turing Machine.
- Turing Machines can only handle a subset of numbers (the computable ones), many real numbers cannot be computed algorithmically.
Richard’s Paradox
- Richard’s Paradox is a paradox that arises when considering definable numbers.
- It states that if we list all meaningful English phrases that describe a decimal number between 0 and 1, we can construct a diagonal number that differs from every number in the list.
- This number cannot be in the list, so it cannot be defined by any English phrase.
- However, by defining how to construct it, we did so in English, creating a paradox.
Logic and Computation
- A logical system is consistent if it is not possible to derive a contradiction within it.
- A logical system is syntactically complete if for any well-formed formula, either the formula or its negation is provable within the system.
- A Turing Machine consists of a tape, a read/write head, a set of states, and instructions in the form of a “Machine Table.”
- The Turing Machine starts in the initial state, with the read/write head positioned at the leftmost cell of the input on the tape.
- The machine stops when it reaches a halting state. The symbols remaining on the tape represent the output of the computation.
Turing Machine as a Model for Human Computation
- Turing described computation as the process of writing symbols on paper.
- The computer is viewed as a person following instructions.
- The machine simulates human calculation by executing simple steps like reading, writing, and changing states.
The Paradox of Computable Numbers
- A computable number is one whose digits can be generated by a machine following a set of instructions.
- Definable numbers may not be computable.
- Suppose there is a way to define real numbers between 0 and 1 by specifying methods for computing them.
- By applying Cantor's diagonalization, a new number can be constructed that differs from every number on the list.
- This new number is uncomputable, but the construction process suggests it is computable, creating a paradox.
Searle's Chinese Room Argument
- Searle’s argument is a strong challenge to computational theories of mind.
- The System Reply: the system of which the man is a part understands Chinese, even if the man himself does not. Searle argues that the system cannot get from the syntax to the semantics.
- The Robot Reply: If the system were embedded in the real world, like in a robot, it might develop semantic understanding. Searle counters that the robot still has no way of getting from syntax to semantics.
Possible Responses to Searle
- Intelligence Without Intentionality: even if an LLM has no intrinsic intentionality, its processing of information is “intelligent” on the basis of its impressive processing of relevant information.
- Intrinsic Intentionality in Abstract Domains: Searle’s argument is less convincing when considering “thought” about abstract entities. Systems like a chess-playing program, while not conscious, exhibit a form of intelligence.
- Going “Concrete” through Robotic Interaction? If we believe intentionality requires interaction with the physical world, robotic AI can achieve it, but Searle argues that the machine still lacks “understanding” in the sense of conscious awareness.
- Combining Robot and System Replies: The man in the Chinese room does not understand Chinese, but the system as a whole may.
What do Machines Lack?
- Searle will deny that robotic lumberjack's states have “semantic content," even with causal relations.
- His arguments suggest that “understanding” in the sense of conscious awareness is the crucial factor.
Intelligence and Consciousness
- Turing believed that machine consciousness is as reasonable as believing that other people are conscious.
- Intelligent thinking need not require consciousness.
- Searle argues that without conscious awareness, machine intelligent behavior is merely a product of syntactic manipulation.
- Machines can demonstrate sophisticated processing capabilities without consciousness.
Are Machines Conscious?
- Consciousness is a causally active process.
- The behavior of computers is well understood and there is no room for another causally active process.
- We do not understand our consciousness, but we do understand enough about how computers work to rule out their being conscious.
Computer Machinery and Intelligence
- The Turing Test provides a context in which a machine’s intelligence can be judged on the basis of performance alone.
- The issue of machine intelligence should be separated from that of consciousness.
- We can accept the possibility of genuine machine intelligence without believing in conscious machines.
