  The proponent of the threshold view may, in response, acknowledge the importance of the ability to control one's experience through acts of will, but still insist that a more robust capacity for autonomy — for example, a capacity that involves expression of values and not just mere preferences — has moral importance of an altogether different order. This difference can then support the position that, in cases of conflicts between an earlier self capable of such robust autonomy and a current self merely capable of exercises of will, the earlier self retains authority and her interests ought to be heeded.
