Sin is: before God, or with the conception of God, in despair not to will to be oneself, or in despair to will to be oneself. Thus sin is intensified weakness or intensified defiance: sin is the intensification of despair. The emphasis is on before God, or with a conception of God; it is the conception of God that makes sin dialectically, ethically, and religiously what lawyers call 'aggravated' despair.
Soren Kierkegaard
