Did the Danish philosopher Soren Kierkegaard play chess? The danish existentialist philosopher Soren Kierkegaard lived from 1813 to 1855.

He writes in one of his journals (21st of May 1839):  


Original Danish  


  Jeg lever i denne Tid omtrent som en Brik i Schakspil maa være
  tilmode, naar Modspilleren siger: den Brik kan ikke røres – som en
  ørkesløs Tilskuer, da min Tid endnu ikke er kommen.




Translation by google:


  I live at this time just like a piece of chess must be, Allowing the opponent to say: that piece cannot be moved - like an idle
  spectator, because my time has not yet come




Alternative translation:


  I feel as if I were a piece in a game of chess, when my oppenent says
  of it:That piece cannot be moved! like a useless bystander, since my
  time has not yet come.
Did the Danish philosopher Soren Kierkegaard play chess?


The answer is a resounding maybe.

Firstly, he has no games established in Fritz database. Of course this doesn't mean he didn't play chess, just that there isn't evidence recorded in the database.

However it must be remembered that chess was invented in the 6th century and is one of the most popular and famous board games of all time. It is reasonable to assume that he either played casually at least once or knew enough about the game to inform his writing.
