This is the Let's deal with the phenomenon of Qualia by denying its existence thesis.

Spot on.

  • Not at all. As the fourth paragraph from the end states, we experience qualia. Rovelli is simply saying that qualia are simply physical processes described from a salient perspective, that is, at a level more abstract than the eletrochemical processes that underlie them.

    It's a bit like pain: to create better analgesics, we need to work at the lower levels closer to the biology, but a patient describing pain to a doctor works at a higher, descriptive level, as does the doctor. Where is the pain, what are its qualities (dull, sharp, shallow, deep, burning, etc.).

    • "We have souls. We have an inner self. We can treat ourselves as transcendental subjects in the Kantian sense. We have emotions and spiritual life; we experience qualia. These entities are not obtained by addition to a physical state, but by subtraction from a complete physical account. Mental processes are physical processes described in a way that captures only their salient characteristics."

      That's the emergence hypothesis. Largely insufficient [1] and the one of every person that doesn't really understand Gödel’s first incompleteness theorem tends to embrace.

      [1] "We can treat ourselves as transcendental subjects" there is a confusion about expressions of a phenomenon (referent) and real phenomenons (object). It denies Qualia by reducing it to a verbal expression supported by an insufficient model of the universe (current state of Physics).
