“Within the strictures of commonsense reality and personal ability, we can choose to do anything we like in this world … with one exception: We cannot choose what any of our choices will be. To do that, we would have to be capable of making ourselves into self-made individuals who can choose what they choose as opposed to being individuals who simply make choices. For instance, we may want to become bodybuilders and choose to do so. But if we do not want to become bodybuilders we cannot make ourselves into someone who does want to be a bodybuilder. For that to happen, there would have to be another self inside us who made us choose to want to become bodybuilders. And inside that self, there would have to be still another self who made that self want to choose to choose to make us want to become bodybuilders.”
