 Different versions of the threshold approach propose somewhat different thresholds for when the current interests of a formerly competent individual cease to be authoritative. It is usually accepted that the mere loss of decision-making capacity is insufficient (Dworkin 1993, 222-29).  Decision-making capacity is context-specific and depends on the complexity of the pertinent information that the decision-maker needs to process. A person may lose the ability to make very complex medical decisions, while still being able to decide perfectly well about simpler everyday matters. Lapses of this nature would not give the surrogate a license to discount the current well-being of the individual in favor of what mattered to him earlier. By contrast, transformations that could leave authority with the past self must involve a more global loss of capacity such that one can no longer generate, in any context, interests of a special, morally weighty type.  In crossing this threshold, one ceases to be a being of a certain morally privileged kind: for instance, one ceases to be an autonomous individual, or one turns from a person into a nonperson. If an autonomous individual loses his capacity for autonomy altogether — the thought then goes — he may have some local (possibly merely illusory) interests associated with the non-autonomous self, but his affairs ought to be conducted in accordance with his earlier wishes expressive of his autonomy. Or, in the parallel version, if a person turns into a nonperson, he may have some local (possibly illusory) interests as a nonperson, but his affairs ought to be conducted so as to advance the interests of the person he used to be.
