Single Idea 4106

[filed under theme 15. Nature of Minds / B. Features of Minds / 5. Qualia / a. Nature of qualia ]

Full Idea

There is a phenomenal difference between a short-sighted person wearing glasses and not; they do not judge that the world is different, but the properties of the experience (the qualia) have changed.

Clarification

'Phenomenal' refers to the raw quality of experience

Gist of Idea

If someone removes their glasses the content of experience remains, but the quality changes

A Reaction

Could be challenged. If a notice becomes unreadable, that is more than the qualia changing.
