4. How does the inverted qualia objection to functionalism work?

Is inverted spectrum possible?

In some cases, the inverted spectrum scenario is clearly possible. For example, if a world is simulated on a computer and we are looking at this world on a screen, perhaps through the eyes of one of the characters in the simulation, then clearly it is possible to invert the spectrum from our perspective.

What is the purpose of inverted spectrum?

The aim of the inverted spectrum is to make plausible the idea that colour experiences could be the same in their colour-representing aspects but inverted in their colour- feeling aspects.

Do inverted spectrum cases show that functionalism is false?

The cumulative empirical evidence from experiments on image inversion suggests that the results of actual spectrum inversion would confirm rather than refute functionalism.

How does the inverted qualia objection to functionalism work?

Inverted spectrum arguments seek to refute physicalism or functionalism about qualia by showing that, even when all the relevant physical (or functional or intentional or behavioural) facts are held constant, the facts about qualia can still vary, and hence that the phenomenal must be over and above the physical (or ...
