Logos, commonly referred to as logic, is a mandatory part of effective communication. Logic is the branch of philosophy dealing with syntactical validity. As important as logic is for effective communication, many fail to employ it conscientiously and formally.

For everyday purposes, statements are judged by whether or not they make sense. Most people reflect on the arcane rules of logos as much as a philosopher most likely thinks about the libraries that drive most computer applications today. Yet everyday people can still write logically, as does the philosopher who uses the computer.

Without logic, composition has a definite void. Logic is the reasoning that links statements to conclusions. If succession is not logical, communication breaks down; the message cannot be conveyed properly. Illogical writing is at best a loose conglomeration of phrases.
