Qualia

Qualia do not exit!
Illusion—through and through.
To which I would append the fact,
To make this argument exact,
That in that case—neither do you.

In the present context, for those who may not be up-to-speed with current-day philosophy, qualia are subjective feelings like tastes, feelings of pain and pleasure, and even self-awareness. Thus they belong to the “private” realm like hypnagogic visions.
