 Philosopher Henry Shue is skeptical; he believes that all rights (regardless of whether they seem more "negative" or "positive") requires both kinds of duties at once.In other words, Shue says that honouring a right will require avoidance (a "negative" duty) but also protective or reparative actions ("positive" duties).The negative positive distinction may be a matter of emphasis; it is therefore unhelpful to describe "any right" as though it requires only one of the two types of duties.
