Most stories tend to emphasize one dimension over the others. Character Motivations are often made most prominent. Still, many stories are written that compare the methods used by characters, question their purposes, or carry a message that a Means of Evaluation is actually the cause of the problem. Some characters become famous for characteristics other than Motivations, such as a notable detective who employs a methodology of Deduction.
Being aware of all four character dimensions adds a level of versatility in creating complex characters as well. Characters might be Archetypal in one dimension, but fall into complex patterns in another. Also, a character may have three Motivations that drive it, yet strive toward a single Purpose that it hopes will satisfy all three. Some characters may not be represented at all in one or more dimensions, making them both more complex and less well-rounded at the same time. To fully make the argument of any story, however, all sixty-four Elements must be represented in one character or another. In addition, a key point to remember is: Unless a character represents at least one Element, it is not fulfilling a dramatic function and is therefore being employed for storytelling only.
