Abstract
In his recent book One World one of Peter Singer's main concerns is the preferential treatment of compatriots. Two aspects of Singer's theoretical reflections on this issue are critically discussed: the use of an impartiality test as basis for the justification of special duties and the resulting condemnation of partial preferences for compatriots. Subsequently, an alternative way to justify special duties is outlined and applied to the case of fellow citizens. It is argued, that partiality to compatriots can be defended, if special duties are regarded as a constitutive part of valuable relationships.
