This may not be the pinnacle of Existential expression, but it certainly is the most formally thought out, and perhaps the densest and technical, depiction of the fundamental idea of being-in-the-world. Whilst Pascal was maybe the first to suggest the existentialist position; it was Heidegger in Being and Time who wrote "...existence is our essence..". This book is contra almost all of the philosophical tradition, from Plato on, and essentially prefigures pretty much all of the 20 century continental thinking.
