Study Notes

Lecture 2: The Unfolding Argument

Today's lecture covers summarizing the paper, analyzing the argument, and previewing illusionism or non-computationalism.
Functions can be implemented on any universal function approximator.
Functions determine behavior, but implementation of functions does not.
If implementation equals experiences, then experience is independent of behavior, leading to the conclusion that a science of consciousness is impossible.
Consciousness is epiphenomenal, meaning consciousness is a byproduct of the algorithm, not influencing any behavior or introspection.
Consciousness' relationship to its function is that it doesn't matter, consciousness is just as a byproduct that is not influenced by the function.
Implementation matters given theories like recurrent processing theory of consciousness and Integrated Information Theory (IIT).
Recurrent processing theory states consciousness arises only during recurrent processing, and IIT defines integration of information as equivalent to consciousness.
Implementationist theories are fundamentally flawed, using behavioral and introspective tests to test the theories which do not follow logical steps and will actually falsify the theory itself.
Functions are independent of implementation, and implementation can be reversed.
An input-output function can be implemented in infinitely many networks that are universal function approximators.
Input can be spike trains, stimuli, TMS pulse etc. and output can be neural input of later brain areas, verbal reports, overt behavior, etc.
Universal Turing machines include RN network, FN network, laptop, cellular automata, cyclic tag system, etc..
An RN can produce opposite behavior as normally observed, and an FN can produce the exact same behavior as normally observed.

Summary of the Argument

Functions can be implemented on any universal function approximator.
Functions determine behavior, while implementation does not.
If implementation equals experiences, then experience is independent of behavior.
A science of consciousness is therefore impossible.

Technical Problems

The relevant notion is Turing completeness, not universal function approximator.
Recurrent networks (RNs) are Turing complete, but feedforward networks (FNs) are probably not.
RNs have closed, infinite loops, while FNs have an infinite number of layers.
It is unclear under what biological circumstances infinite loops are needed.
The claim that FNs can instantiate any function is false.
Function definition for the theory is not explicitly defined, and is unclear what input/output functions are relevant to science.
Not clear if the argument is relevant to biology, as only overt behavior is focused on and not on subjective conscious experience.

Doerig et al.’s Argument

Input = external stimuli
Output = overt behavior
Every Turing complete system can instantiate any i/o function.
If a theory claims that only certain Turing complete systems create consciousness (e.g., biological systems) then no behavioral data can ever be acquired to falsify this theory.

Implementation Does Not Matter

The implementation of a function does not affect the behavior.
Behavior will be the same in different implementations.
Replacing biological parts with a machine that copies the function will result in the same behavioral output but not be able to have subjective experiences

Analysis of the Argument

There is no way to prove, or disapprove consciousness (i.e., an introspection paradox).
You can't measure consciousness, only behavior that could be caused by something else and not consciousness.

Implications for Consciousness Science

If the i/o function is the same but the implementation differs, then measuring the behavior can not distinguish which one has awareness/consciousness.
This implies that consciousness and implementations are unrelated
Empirical science requires grounding cognition in overt behavior; otherwise, theories cannot be falsified.

Illusionism or Non-computationalism

Doerig’s argument can be clarified; input = external stimuli, output = overt behaviors/beliefs and cognition.
Sensory experiences are not deducible from I/O functions.
All beliefs/reports are caused by I/O function.
Sensory experiences are epiphenomenal in relation to beliefs.
Sensory experiences are decoupled from thoughts and behavior, so a science of consciousness is impossible.
If consciousness is not measurable then it is outside of science.
