Why more and more people prefix their description of themselves(or their knowledge about themselves) with their national , civilizational, ethnic extraction or belonging. 
When people say : western science, or western civilization or islamic science, or chinese science etc what do they mean by that?
Does  a french, german or an english man who never studied Fourier or Turing  or Hilbert have more right for appropriation than an afghan or a papu who not only made it his job to know those scientists but made it his passion and his field of expertise ?
