It is 1990. CSEP has just received a letter from a professor of chemistry at Witwatersrand University, Union of South Africa, asking that he be added to CSEP's mailing list so that he can receive Perspectives (free of charge). Should CSEP treat this request as it would any other and add him to the mailing list? Or should CSEP treat his request differently, should CSEP refuse it outright, ask the chemistry professor his views on apartheid, or in some other way seek to boycott selectively? Does it matter that Witwatersrand is the premier Afrikaner university, a stronghold of apartheid? Would your answer be different if the time were now (rather than 1990) and the letter came from the University of Belgrade (rather than Witwatersrand)? Would it matter if the letter came from a politician-philosopher like Mihajlo Markovic (rather than from a political chemist)? What role, if any, should the content of Perspectives have in determining what to do?
