Qualia (Wikipedia)

In philosophy of mind, qualia (/ˈkwɑːliə, ˈkw-/; sg.: quale /-li/) are defined as instances of subjective, conscious experience. The term qualia derives from the Latin neuter plural form (qualia) of the Latin adjective quālis (Latin pronunciation: [ˈkʷaːlɪs]) meaning "of what sort" or "of what kind" in relation to a specific instance, such as "what it is like to taste a specific apple — this particular apple now".

The "redness" of red is a commonly used example of a quale.

Examples of qualia include the perceived sensation of pain of a headache, the taste of wine, and the redness of an evening sky. As qualitative characteristics of sensation, qualia stand in contrast to propositional attitudes, where the focus is on beliefs about experience rather than what it is directly like to be experiencing.

American philosopher Charles Sanders Peirce introduced the term quale in philosophy in 1866, and in 1929 C. I. Lewis was the first to use the term "qualia" in its generally agreed upon modern sense. Frank Jackson later defined qualia as "...certain features of the bodily sensations especially, but also of certain perceptual experiences, which no amount of purely physical information includes". Philosopher and cognitive scientist Daniel Dennett suggested that qualia was "an unfamiliar term for something that could not be more familiar to each of us: the ways things seem to us".

The nature and existence of qualia under various definitions remain controversial. Much of the debate over the importance of qualia hinges on the definition of the term, and various philosophers emphasize or deny the existence of certain features of qualia. Some philosophers of mind, like Daniel Dennett, argue that qualia do not exist. Other philosophers, as well as neuroscientists and neurologists, believe qualia exist and that the desire by some philosophers to disregard qualia is based on an erroneous interpretation of what constitutes science.
