What is the theme in A Kierkegaard Anthology by Robert Bretall?

How is Knowledge Possible? resonates as a theme. The Philosophical Fragments were written in order to set-up the question that is answered by the Concluding Unscientific Postscript. However, the question may in some ways be the more important task. Kierkegaard's question is "How far does the Truth admit of being learned?" It may initially seem that man cannot have real knowledge. He is concerned too much with his present circumstances and is shaped too much by historical factors to have any real mental contact with the world of things as they are, or with "eternal consciousness." How can consciousness reach outside of itself? After all, are not we always taking our own perspective? How can an objective perspective even be possible?
