eliminativists want to prove that humans, like the blue-minimizing robot, don’t have anything of the sort until you start looking at high level abstractions.
Just because something only exists at high levels of abstraction doesn’t mean it’s not real or explanatory. Surely the important question is whether humans genuinely have preferences that explain their behaviour (or at least whether a preference system can occasionally explain their behaviour—even if their behaviour is truly explained by the interaction of numerous systems) rather than how these preferences are encoded.
The information in a jpeg file that indicates a particular pixel should be red cannot be analysed down to a single bit that doesn’t do anything else, that doesn’t mean that there isn’t a sense in which the red pixel genuinely exists. Preferences could exist and be encoded holographically in the brain. Whether you can find a specific neuron or not is completely irrelevant to their reality.
Most of us allocate a particular percentage to charity, despite the fact that most people would say that nearly nothing we spend money on is as important as saving childrens lives.
I don’t know whether you think it’s that we overestimate how much we value saving childrens lives, or underestimate how important xbox games, social events, large tvs and eating tasty food are to us. Or perhaps you think it’s none of that, and that we’re being simply irrational.
I doubt that anyone could consistently live as if the difference between choice of renting a nice flat and renting a dive was one life per month, or that halving normal grocery consumption for a month was a childs life that month, etc. If that’s really the aim, we’re going to have to do a significant amount of emotional engineering.
I also want to stick up for the necessity of analysing the way that a charity works, not just what they do. For example, charities that employ local people and local equipment may save fewer people per dollar in the short term, but may be less likely to create a culture of dependence, and may be more sustainable in the long term. These considerations are important too.
