It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.
Soren KierkegaardThe ever increasing intensity of despair depends upon the degree of consciousness or is proportionate to this increase: the greater the degree of consciousness, the more intensive the despair. This is everywhere apparent, most clearly in despair at its maximum and minimum. The devil's despair is the most intensive despair, for the devil is sheer spirit and hence unqualified consciousness and transparency; there is no obscurity in the devil that could serve as a mitigating excuse. Therefore, his despair is the most absolute defiance. . . .
