Suppose I have a coffee machine. I can weigh it, clean it, measure titration. But is the machine edible? No, because the machine isn't coffee per se. Similarly

Suppose I have a coffee machine. I can weigh it, clean it, measure titration. But is the machine edible? No, because the machine isn't coffee per se. Similarly, suppose scientists discover a neural-structure (or chemical-interaction, etc) responsible for blueness. I can dissect it, electrocute it, soak it in LSD. But will the scientists experience blueness? No, because the structure isn't qualia per se. The prevailing ideology is that by studying the mechanical nature of coffee machines, we'll ipso facto understand the biochemistry of the beverage. danielam is arguing that this ideology is probably wrong. This is why the Problem of Qualia is a problem.
