(1) What is functionalism? What are the pros and cons of functionalism? Explain how you would challenge functionalism.

The theory of functionalism first entered the world of philosophy and, more specifically, the world of materialism, at a time when the identity theory and behaviourism were beginning to be questioned. Advocates of functionalism use the theory to explain mental causation, a concept that behaviourism did not address, and multiple realisation, a concept that the identity theory was unable to explain. Mental causation is the notion that the mental state of a being is causing the individual’s behaviour. Multiple realisation is the idea that any person and any species can experience the same sensation, despite differences in physical structure and wiring.

However, unlike the original intrasubjective version, they do not realise that this change has occurred and do not remember that they used to see the green of grass differently, nor do they sense any difference in feeling when looking at grass. In this scenario, there is no possibility of behavioural differences, as the person does not even know that they are experiencing qualitative differences. If this this true, then for the inverted spectrum to occur, in this scenario, there would be qualitative differences without behavioural differences – meaning that functionalism would have to be false for the inverted spectrum to be true. This scenario appears to be possible, so functionalism must be
