Quora Answer: Who do you consider the greatest philosopher of the 20th century?

Heidegger is the clear winner here. If you look at the number of commentaries, the number of other philosophers who refer back to Heidegger, and the profundity of his work, one has to conclude that thinking in the twentieth century after Being and Time was profoundly changed, but not as much as it will be changed in the twenty-first century by his recently releasedContributions to Philosophy.
