We can't decide whether something is pleasurable or painful. It's immediate, pre-rational.
Am I missing something here? If this would be the case, we could throw Epicurean calculus out of a window, forget about any form of philosophy and jump from the nearest, highest building because flying sounds like something cool to do this Monday evening.
Good point. I should clarify my point.
My understanding is that we can experience pleasure or pain, per Epicurus and modern neuroscience (pleasure vs displeasure/pain). The feeling itself is automatic. You experience one of the two. That's why you pull your hand away from a hot stove. That's why you make yummy noises when you eat something you enjoy.
That said, we can *choose* whether or not to engage in an experience - to fulfill a desire - be it one we anticipate pleasure or one we anticipate will be painful that leads to pleasure.
But the feeling *itself* is pleasurable or painful before we put a rational value on it.
