The online magazine The Best Schools has just published a list of the 50 Most Influential Living Philosophers. Among them we find Professor Ingvar Johansson. A representative of TBS informs that the list was compiled partly using a tool developed by TBS to determine links to the works of the philosophers in question, page views, book and article citations and more. They also used a tool called SEMrush to determine the traffic to home pages, wiki pages, etc., in order to get an estimate of what they call Influence Networks. TBS’s team included four Philosophy PhD’s and in addition they consulted numerous philosophers to balance the quantitative data they collected.
