"...whereas anxiety is freedom's actuality as the possibility of possibility."
"That anxiety makes its appearance is the pivot upon which everything turns. [Human beings are] a synthesis of the psychical and the physical; however, a synthesis is unthinkable if the two are not united in a third. This third is spirit... In innocence...spirit is present, but as immediate, as dreaming."
--from Soren Kierkegaard's The Concept of Anxiety
