4-Dimensional Reading

In Chapter 2, it became apparent that this book would not be easy to follow given that the narrator described Billy Pilgrim interacting with aliens and time traveling in increments of years at a time. Billy says that the alien creatures he supposedly met are called Tralfamadorians, and they are "friendly and they can see in four dimensions. They pitied Earthlings for being able to see only three. They had so many wonderful things to teach Earthlings, especially about time" (Vonnegut 26).

The book seems to portray time as simply a fourth dimension instead of describing events as if they occur in chronological order. Since Billy knew of the Tralfamadorians' desire to teach Earthlings about time, perhaps the book he wrote (Sam) was an attempt at educating humans as to what time really is. 

There could also be a deeper meaning to Earthlings being able to only see three dimensions. Since this was described as an anti-war book in Chapter 1, the lack of a fourth dimension could explain why war exists. Humans are foolish, selfish, and cruel. This could all be as a result of seeing time so narrowly, and the Tralfamadorians sought to teach Earthlings to see time as a fourth dimension and therefore eliminate some undesirable traits that accompany humanity. If this is what Vonnegut meant, does he really believe in these Tralfamadorians and what they say about time?
