Anti-Climacus

That's rather the point, old sport: there are many things in life we neither create of our own accord nor can ever understand in the conventional sense of the world. A fully-formed life does not shy away from these areas because they lack the sort of certainty we might crave: that something is difficult, as Rilke said, is all the more reason for us to do it. There will always be, if nothing else, love and death: not meant to be understood, which is a good thing, because our powers and vastly insufficient for what that understanding would require. This is the trembling point, at which we must admit our own powerlessness: everything worthwhile flows from this.
