Causal powers maintained if simulation low-level
OpposingArgument
1
#796
The person whose neurotransmitters have been replaced still understands Chinese because she still has the right causal powers; she just needs some help from the demon.
The demon simulation is low-level enough that the relevant causal effects—the physical simulation of neurons—are still initiated, and so intentionality is maintained.
John Searle 1980a, 1980b, 1990b.

Understanding arises from right causal powers☜Systems capable of semantic understanding and intentionality must have at least the same causal powers as brains. Brains have sufficient causal powers to produce understanding: its an open empirical question whether other materials (eg silicon) do.☜98CE71

Chinese Room style argument shows causal powers insufficient☜We can replace a relevant causal power in a Chinese speakers brain—eg neurotransmitters—with a demon that simulates the causal powers function without understanding Chinese; hence having the right causal powers isnt sufficient for understanding.☜EF597B

The series of Chinese simulators☜Imagine a series of thought experiments in which a demon replaces one to all of a speakers neurons. As more neurons are replaced, and the degree of simulation increases, when does the person cease to understand Chinese? ☜EF597B
