Qualia

The term qualia (singular 'quale') is used in many different ways to date. Let's distinguish:

1. Characterizations in terms of examples
2. The kind of term that is being defined (Can one call this the "logical structure" of the term? - Probably not, please correct.)
3. Properties or features ascribed to qualia

Definition in terms of examples

May publications define the term using examples. E.g.:

• Colours ("seeing red", etc.)
• Using the what it is like to be reference

Logical structure

Various uses seem to appear:

• Qualia are "introspectively accessible, phenomenal aspects of our mental lives"
• Properties of phenomenal consciousness
• Simple constituents of phenomenal consciousness (going as far as "approximations" of phenomenal consciousness)
• States of phenomenal consciousness
