This story resembles a fairy tale in that there is a problem and a journey to find a solution. As the story goes on, each of the men is referred to as whatever he considered Truth. Thus, the story is more about the opposition between Science, Theology, Love, Gold, Wine, and the Fairy Tale, than the people themselves. In addition, the description of the Fairy Tale was very perfect and inhuman. This contributed to the typical timeless, placeless, magical feel of the fairy tale.
I think Carl Ewald uses this story to make some kind of point about Truth and its interpretations. Although, the fact that he construes the Fairy Tale in the end as the "real" Truth is interesting. Obviously, fairy tales are not realistic, so maybe the fact that he compares them to Truth says something about his disbelief in a real Truth or that Truth cannot be interpreted in one single way or found in one particular place.
The biographical notes mentioned that he wrote to incorporate his views on social Darwinism. So, perhaps this can be included in the interpretation of his message?
