Seyyed Hossein Nasr is among the world's top 50 Muslims, according to The Royal Islamic Strategic Studies Centre in Jordan, which has published a report on The 500 Most Influential Muslims in the World in conjunction with the Prince Alwaleed Bin Talal Center for Muslim-Christian Understanding at Georgetown University.
In a list headed by Saudi King Abdullah bin Abdul Aziz, Nasr comes as #47, just after Dr Abdul Qadeer Khan, father of Pakistan's nuclear bomb (and of a certain amount of nuclear proliferation). Of course such lists are ridiculous, and probably say more about the perspectives of those who compile them than about reality, but they still mean something. It is interesting that Nasr makes the list, and also interesting that his two main achievements are given as "Reviver of Tradition" and "Islamic Environmentalism." The list's authors consider the environment number 2 of the 12 "issues of the day," and put Nasr as the leading figure under that issue.
Among the full 500, I recogize two other Maryamis, two non-Maryami Traditionalists, and two others for whom Traditionalism was at some point important.
Thanks to I. P. for drawing my attention to the list.
