In this paper I argue that Kierkegaard's theory of change is motivated by a robust notion of contingency. His view of contingency is sharply juxtaposed with a strong notion of absolute necessity. I show that how he understands these notions explains certain ambiguous claims he makes about causation. I attempt to provide a coherent interpretation of his view of causality that is consistent with both human choice and the causal sequence of change. I end by suggesting a compatibilist interpretation of Kierkegaard's philosophy.
