The Sickness unto Death presents a startlingly modern view of the self as non-substantialist, emergent, and process-driven. Instead of an immaterial soul or metaphysical essence, Kierkegaard’s self is a state of the human body and mind in “synthesis,” something human beings can become (or fail to become) through relating to themselves in a particular way. But the self is also presented in this work as an essentially eschatological being. While the self may be formed in and through its social context, Anti-Climacus returns again and again to the idea that the self is at heart the subject of an eternal judgment. This has significant implications both for what Kierkegaard takes selves – and by extension each of us – to be, and how we understand the temporality within which beings like us live.
