a rational sense of how things are related
Original Dramatica Definition
Logic is the mental process of choosing the most efficient course or explanation based on reason. The Logic characteristic exemplifies the theory behind "Occam's Razor," that the simplest explanation is the correct explanation. Therefore, the Logic characteristic is very efficient but has no understanding or tolerance that people do not live by reason alone. As a result, the character with the Logic characteristic often ignores how other's "unreasonable" feelings may cause a very real backlash to his approach.
