Now that we have discussed the 8 different narrators, lets look at the relationship between POV and the writing's degree of objectivity or subjectivity. First a couple of definitions.
Subjective Writing: The writer seeks to record the feelings and sensibilities behind his/her characters' thoughts, statements, and actions.
Objective Writing: The writer leaves it up to the reader to imagine/determine the feelings and sensibilities behind each character's thoughts, statements and actions.
Subjective writing enters into the thoughts and feelings of a character, whereas objective does not. It should be noted that POV does not determine whether writing is subjective or objective. What is the determining factor is how much of the character's emotions, feelings are explicitly described. In subjective there is a great amount of detail. Objective, on the other hand, has little if any. Hemingway's The Sun Also Rises was written using objective writing. Harper Lee's classic, To Kill A Mockingbird, uses subjective. LeCarre's The Spy Who Came In From The Cold utilizes both forms.
So, by now you may be asking yourself, "Which style of writing should I use?" The answer is simple, which ever comes naturally to you. Some writers are naturally subjective (this is especially true of the majority of new writers) and others are objective.
Writing is possibly the most personal endeavor done by Human Beings. No one can write for you, you must do it alone. You can get plenty of assistance from a good critique group once the writing is done. Until you write it there is nothing to critique. The greatest thing about writing (at least for me) is POWER! Can anyone think of any other endeavor where you are in effect GOD? You control the weather, locale, feelings, emotions and yes, even whether a character lives or dies... Now how cool is that?
Finally, the most important piece of information in this series appeared in this blog entry. It is: Write what comes natural to you; let your voice flow. Nothing is any more difficult than attempting to write against your grain, so to speak. Just watch out for those inadvertent POV shifts!
