If there were no eternal consciousness in a man, if at the bottom of everything there were only a wild ferment, a power that twisting in dark passion… - Søren Kierkegaard

Spontaneous love can reach the point of despair, shows that it is in despair, that even when it is happy it loves with the power of despair.

Someone in despair despairs over something. So, for a moment, it seems, but only for a moment. That same instant the true despair shows itself, or despair in its true guise. In despairing over something he was really despairing over himself, and he wants now to be rid of himself.

one cannot seek for what he knows, and it seems equally impossible for him to seek for what he does not know. For what a man knows he cannot seek, since he knows it; and what he does not know he cannot seek, since he does not even know for what to seek.
