Guess these Philosophers, which in my Opinion had the most influence on Philosophy itself, as well as the rest of the world.
Some of the listed philosophers didn't wrote books, so I tried to give hints by describing their main distributions or giving a famous quote.
I find the inclusion of a view non-Western philosophers almost worse than to include none at all. Given the rather many medieval philosophers included, the fact that only one---Avicenna---wrote in Arabic isn't quite appropriate. Including Albertus Magnus but not Averroes, for example, doesn't seem fitting.
The same goes for Chinese philosophy (surely Mencius has been more influential than quite a few listed here!). Indian philosophy is not represented at all.
