Heidegger’s existentialism centres on “Dasein,” or being, which he describes as something we are “thrown” into. I find Martin Buber’s view more compelling: in Ich und Du—I and Thou—meaning arises through relationship. Buber contrasts the distance of addressing others as “Sie” with the deeper relatedness of encountering them as “Du,” or “Thou.” For me, the essence of existence lies not in Dasein, but in what we might call Dusein : being with Thou.
Our brother whose heart be heaven
(Our sister, our father, mother)
Hallowed be thy pain
Our kingdoms come
When will is one
On earth as it is in heaven
…
lead us out of that isolation
Which delivers each to evil
