In an important Journal entry (VII 1 A 181) Kierkegaard describes the dialectic of human freedom in relation to divine omnipotence. This dialectic is difficult to grasp in that it differs from that of relative power. Relative power exists in its use, in the extent to which the powerful one can inflict his/her will on others. Relative power has to with the overcoming of opposition. Kierkegaard argues that absolute power need not exert itself in this way. There is no effective opposition to its purposes. It shows might, not in force, but in allowing its purposes to be accomplished freely by those who freely choose to cooperate with or to oppose its'purposes, but, in either case, simply further them. The Concept of Anxiety takes this theological paradox and applies it to psychology. The "ground" of anxiety (if we may here speak of ground where all is groundlessness) is the ambivalence of freedom. One must choose and in the choosing one's heart is revealed. It is so because there is no compulsion to our choice, not our biology nor our upbringing nor even God. This freedom, therefore manifests itself as dizziness, as vertigo, as anxiety, because possibility opens out before us as an abyss. Anxiety is a complete ambivalence, a sympathetic antipathy and an antipathetic sympathy, a simultaneous attraction to and repulsion from our own freedom. The leads our author (Vigilius Haufniensis "The Watcher of Copenhagen") into his brilliant discussion of the Myth of the Fall and human sin. The "Dogmatic Issue of Hereditary sin" is to be mapped on to human psychology. Oddly enough, this is no slavish following of Christian Dogma as it is taught. Haufniensis makes a decisive break with Christian dogmatics since Augustine in asserting that "Hereditary Sin" is not transmitted by sex. We are do not inherit sin. We are not born into sin. By anxiety, sin enters the world. Anxiety, not birth, is the proper antecedent to sin. Kierkegaard interprets the Myth of the Fall as the story of every human being. Adam is the race. We are, each of us, Adam. We have all of us committed an original sin. We had no idea, prior to sinning the first time, what sin meant. We only knew the anxiety. Having sinned, we know now that, by a sin, sin enters the world. Sin is never necessary, it is always a free act. Sin is chosen and once chosen reveals itself as a trap. Then our anxiety reaches a new height. This heightened anxiety may lead us to perdition or to seek God's forgiveness, thus is the heart revealed. The only thing I can compare this work to is Nietzsche's "Genealogy of Morals", and that compares to this as lightning to the lightning bug. It is a very brilliant, if difficult work. There is, however, another important reason for reading this book: its' sister and repetition is "Sickness Unto Death" and reading this one greatly enhances the experience of reading that.
