> In the field of Consciousness studies, resolving the direct *mechanisms* of physical and neural operation are examples of what are called "easy problems" (relatively speaking). The far more difficult problem lies in fully describing states of *subjective experience*: this is known as the "hard problem". For example, Why is it that when our brains process light of a certain wavelength, we might have an *experience* of deep purple and not, say, of faded pink? Why is it so difficult to describe to someone else what an orgasm feels like, or why getting tickled is unpleasant,

Unpleasant, that is, for some people. No, I'm not kidding, and I assume the ones who find it pleasant are still human.
