Olivier argues that "There is no obvious reason why it should be unhealthy or abnormal for different literatures to co-exist in one country, each possessing its own infrastructure and allowing theoreticians to develop impressive theories about polysystems". Yet political idealism proposing a unified "South Africa" (a remnant of the colonial British approach) has seeped into literary discourse and demands a unified national literature, which does not exist and has to be fabricated. It is unrealistic to ever think of South Africa and South African literature as homogenous, now or in the near or distant future, since the only reason it is a country at all is the interference of European colonial powers. This is not a racial issue, but rather has to do with culture, heritage and tradition (and indeed the constitution celebrates diversity). Rather, it seems more sensible to discuss South African literature as literature produced within the national borders by the different cultures and language groups inhabiting these borders. Otherwise the danger is emphasising one literary system at the expense of another, and more often than not, the beneficiary is English, with the African languages being ignored. The distinction "black" and "white" literature is further a remnant of colonialism that should be replaced by drawing distinctions between literary systems based on language affiliation rather than race.
