The basis of this discussion is the difference between two-dimensional and three-dimensional characters in literature, and how either kind could or should be used in fiction. In my experience, I have found that plenty of real life people are quite two-dimensional, and therefore, I don't feel all that bad including a myriad of two-dimensional characters in some of my stories. For anyone unsure of the terminology, two-dimensional is meant to refer to anyone who has a singular motive and in most cases never strays from a sole set of convictions and desires; these can range from the archetypal thief or knight who operate purely off of greed or duty, to the high school jock bent on remaining tough and popular, or even the mad scientist whose respect for science and discovery betrays all human compassion or sympathy. Anyways, I hope you get the idea - two-dimensional characters typically lack a certain degree of depth, and behave according to a very black and white worldview. However, three-dimensional characters exhibit qualities that make it difficult to completely dislike or actively root for them, which is certainly a trait seen occasionally in the real world. These kinds of people, for whatever reason, may also have a single goal they strive towards, but how and why they want to achieve that goal may require them to betray an individual nature they've been acclimated to their entire lives. It's been said that George R.R. Martin accomplishes this idea very well, and I would have to agree, but I'm very curious as to why such a concept is so popular when a majority of the human populace clearly falls into the first category. Feel free to share your thoughts or preferences of two-dimensional and three-dimensional characters, and I would like to ask you some interesting questions about yourselves: If you were a character in a story (exactly as you are in the real world), do you think you would be a two-dimensional or a three-dimensional character? Really give it some thought; is there ANYTHING you wouldn't do to get what you want? Is there a particular set of rules you live your life by that you wouldn't even CONSIDER going against, even if the result might be ethically unpleasing or detrimental to your goals?
