Or More Accurately: Is Not.
I often hear the statement, “Your writing must reflect your beliefs.” I personally find this a ludicrous statement. My current work, for instance, is a Hellenistic Fantasy written with full polytheistic pantheons, the possibility of apotheosis, Pre-Christian philosophy regarding Government, Civics, and Economics, and the general presupposition that all war is Holy War. In short, it is a Fantasy Recreation of the world of Rome and Carthage in the Punic Wars. Minus even the far-off influence of Judaism and Monolatry (if not true Monotheism). My lead characters all operate within the views of that world. One a priestess whose Patron oversees Love, Beauty, Trade, and the City, as Tanith did Carthage. Nor do I apologize for their own personal agendas, some of which include things we consider quite odious in the modern world: Slavery, for instance, was commonplace in the era. Well over half the Roman population was servile. Carthage could not have functioned without them either. It would be a gross disservice to insert modern considerations on the topic into that setting. They simply did not exist.
The person who Tarien Cole inhabits has a very distinct set of values. Despite my love of steampunk, I enjoy my modern conveniences, thank you. Despite the fact my current WIP comes from a ‘pagan’ setting, I am comfortably Christian in confession. And I have other works where that faith does occur in characters. Including a Historical Fantasy set in 16th Century Prague with a Brandenburg-born Bohemian Lutheran with Calvinist sympathies (who takes a Romani sorceress as his wife). Despite the fact the economic system of both of those worlds predates Adam Smith, I am a believer in the Free Market.
In short, most of my works have little relation to me. Some have virtually none. I don’t, as a rule, cut snippets of myself off and make characters out of them. In fact, I made the lead male character of my Steampunk as divergent from myself in personality as I could imagine. Just to see if I could! Hence his rather Indiana Jones-ish mentality to everything from women to problem solving.
Am I saying it’s wrong to do that? No. There are no ‘right or wrongs’ in writing, except this: “Thou Shall Not Bore Thy Reader. Because That Simply Sucks.”
I happen to enjoy making characters from what I observe. In history, in reading, and in the setting itself as I formulate it. I don’t pre-program parts of myself into the story. And even when a character ‘somewhat’ aligns with myself, I’m still responsible as a writer to answer questions AS THE CHARACTER. Not as me. So again, I am almost always endeavoring to divorce myself from the process, and listen to the characters.
They are not me. They may be my friends (though their murderous, sadistic author has a strange way of showing it). But I am not a metanarrator. Consider this one more reason I resent using fiction as a method of message.
