Life Can Only Be Understood Backwards

From Søren Kierkegaard's journal entry IV A 164, dated 1843 — the same year he published Either/Or and Fear and Trembling. The entry reads: "It is quite true what philosophy says: that life can only be understood backwards. But that makes one forget the other saying: that it must be lived — forwards." Kierkegaard is not simply making a point about memory; he is drawing attention to the irreducible temporal structure of existing: we always act under uncertainty about outcomes we will only understand in retrospect. This asymmetry between lived experience and retrospective understanding is central to his critique of Hegel's systematic philosophy.
