Abstract
Now that there is more distance from Existentialism as a movement in philosophy, after its influence has passed to other forms, this collection of writings by its founding members can help raise the question about just what existentialism is. Langiulli writes an interesting and freer new introduction to this 25-year-old collection. He makes a good case for looking back to the philosophical sources to see again what existentialism had and still has a hold of. He implies that “post-modernism, deconstructionism, antifoundationalism, historicism, multiculturalism, and diversityism,” while stemming from existentialism, also forget what existentialism was onto.
