quale

Pitch is a "quale", it is purely perceptual, and not measured in Hz.

[Descartes] - "There is such a thing, as what it's like to be..." [Nagel, in the posted paper] - There's such a thing, as what seeing red is like: a quale.

When we think "I seems that [quale]" we are correct, but every time we create a physical artifact to that effect, we are wrong.

Who I am really is a quale in my head and no use to anyone else - so instead we find ways to distinguish bags of meat and call it identity

This complex millieu of properties, states, dispositions, etc, all serve to inform the properties of a quale.

But this representational power must be intrinsic to the structure that constitutes a quale.

Similarly, we can imagine a human who is genetically engineered for his skin to pinch when he hears certain sounds, so that he would feel the pinching quale.

Look at a glass of milk at sunset; the way it looks to you--the particular, personal, subjective visual quality of the glass of milk is the quale of your visual experience at the moment.

The way the milk tastes to you then is another, gustatory quale, and how it sounds to you as you swallow is an auditory quale; These various "properties of conscious experience" are prime examples of qualia.

For example, the red quale tells you something about red substances in the context of the space of possible colors, the external world full of beneficial and harmful substances, and the bearer of the quale with drives, dispositions, preferred states, etc.

This suggests to me that some kind of recurrent structure is a necessary condition for a quale: to simultaneously be the producer and the consumer of a representative state, and consume in such a way that necessarily confers competent behavior.
