I say “Free Will” is a natural progression from the unconscious tendency to avoid feeling pain to the conscious decision to risk feeling pain. That’s why I’ve just decided that mine are the eyes I’d willingly donate to cognitive neuroscience, since for the kind of free will (that most people are sometimes said to cherish) to be shown to be real (to the so-called hard determinist) it will need to be shown that imagining what it is like to have needles poked in your eyes for the sake of some kind of musical interpretation or another ought to have been good enough proof of the kind of free will that most people have sometimes been said to have cherished in the first place.
In other words, Sam (and the like), all I’m saying is… this is an offer for a live tissue donation. I’ll organise all the recording techniques and the staff. All you have to do is poke the needles in my eyes and try to keep a straight face while you’re asking me if it’s hurting.
