Regarding “the taste of wine”. I have for uninteresting reasons never gotten drunk, never trained my brain to associate positive feelings with wine or alcohol. As a result, wine for me subjectively is elaborate fruit juice. When I am given a fancy wine, I can taste the components people describe, but the subjective experience they have of the amazing taste I do not share, because I simply don’t have those associations. Similarly for beer my subjective experience is an association of disgust. Those of us who believe neurons are all there is are simply arguing everything is just abstractions and associations, just neurons firing. What you call a subjective experience is a particular set of neurons firing as a response to stimuli. There is nothing more than that, and while you can form an abstraction in your brain that describes something more than that, this would be an example of an improperly trained neural net.
