One would have to go beyond the actual words of the novel, “The Swiss Family Robinson,” to see any weaknesses in the father, the main character of the book. The way he is depicted by the author he is almost perfect; no, he is perfect. He knows just about everything: what kind of plants and trees are on the island; what kinds of animals live there; and last but not least, how to survive on the deserted island. He is also the spiritual leader of the family, and is constantly giving sermons while he’s giving out lessons on survival.
The main flaw in the father is that he is too perfect. He has no flaws that one can find in the book, and that makes him a one-dimensional character, which you hardly ever find in a classic novel. “The Swiss Family Robinson” is a classic only because of the adventures that the family has, not in the way that the author develops his characters, especially the father.
