But because all communication, and therefore shared experience, relies on prior common experience and perception, we can't be certain that what my wife sees as pink matches what you see as pink. In fact, I would argue that our perceptions have to be different or we would all like the same foods, sounds, smells, visual arts, and other sensory experiences because they would always be pleasing if we all perceived them the same. I find Mahler interesting, but most people can't stand his work. I find Charles Ives' music amazing, but again, many can't stand it. Why? Because my perception makes that music pleasing to me. at the same time, I find most country music gets on my nerves, but a large group of people love country music.
Favorite foods and hated foods, the perception of taste and smell is different therefore whether they stimulate the endorphins that tell you they are pleasing or not is different.
Art... I find some art to be a visual cacphony while other artists work are simply sublime. Someone else may find their are diametrically opposed to my views regarding the same artists.
And the real kicker is the masochist who enjoys and finds pleasure in pain while others (myself included) avoid pain at all costs.
