Thank you, Kierkegaard:
“One may liken dread to dizziness. He whose eye chance to look down into the yawning abyss becomes dizzy. But the reason for it is just as much his eye as it is the precipice. for suppose he had not looked down.
“Thus dread is the dizziness of freedom which occurs when the spirit would posit the synthesis, and freedom then gazes down into its own possibility, grasping at finiteness to sustain itself. In this dizziness freedom succumbs. Further than this psychology cannot go and will not. That very instant everything is changed, and when freedom rises again it sees that it is guilty. Between these two instants lies the leap, which no science has explained or can explain. He who becomes guilty in dread becomes as ambiguously guilty as it is possible to be… In dread there is the egoistic infinity of possibility, which does not tempt like a definite choice, but alarms and fascinates with its sweet anxiety.”
