In the second volume of Either/Or, one of Kierkegaard’s pseudonyms observes: There is something unexplainable in depression [Tungsind]. A person with a sorrow or a worry knows why he sorrows or worries. If a depressed person is asked what the reason is, what it is that weighs [tynge] on him, he will answer: I do not know; I cannot explain it. Therein lies the limitlessness of depression.5
