The attribution of “phenomenal” properties to conscious experience is actually a form of intellectual progress. It is a measure of the degree of insight into the nature of consciousness that the human race has attained. One aspect of this progress is the awareness that there is some tension between physicalism and the existence of phenomenal properties, or that the nature of that relationship is not understood.
Dennett and Frankish want to believe that physicalism is true, without any need for peculiar modifications like property dualism, panpsychism, and so forth. When it comes to the properties of conscious experience, they seem to resort either to eliminativism (the properties don’t exist) or functionalism (the properties are just causal and structural properties of the brain). Of these two, functionalism might be psychologically healthier, in that you aren’t denying that you have experiences, you are just telling yourself that they are really brain states or computational states.
I don’t endorse every idea about consciousness that the illusionists oppose. For example, I see no reason to suppose that conscious experience is ineffable. We describe our mind states to each other all the time, using words, and greatly refined versions of these descriptions are no doubt possible. On the other hand, that mind states are private seems obvious: I have access to my own mental state but not to yours.
Regarding your own agenda, you want consciousness to be understood well enough that “hedonium” could be designed. OK, but it’s a little strange to write as if only illusionists are trying to understand consciousness in the relevant way. As I implied, functionalism seems a better name for your research program than illusionism.
Could we please have a quantitative argument, not just that people pay back less interest under inflation-indexed loans, but that there is more money to be spent on productive things, or some other conclusion that genuinely corresponds to greater prosperity?
There is the same amount of money in the system, with and without indexation, yes? I asked you in a private message if indexation means less concentration of money in the banks, but you said no. So please explain how the different distribution of money under indexation is better for everyone, or for the majority of people.
