This discussion involves different aspects of multidimensional phenomenon of national belonging and additionally relates to the definitions of 'Serbian philosophers' and 'Serbian philosophy'. A thesis is defended that, in order to understand and determine national cobelonging it is most appropriate to locate it in the cross section of basic ethnic identity of the genus on the one side and further constitutive cultural/historical identity on the other side, further to be explained through their fusion. Nation co-belonging actually has three dimensions: genetic/generic, personal/decisionistic and cultural/historical. In this regard, Serbian philosophy is then defined in its basic sense as primarily those concepts created and defended by authors - personal holders of Serbian national identity.
