I try not to think about theme when I am writing. Falling in that pit is the quickest way to lose a story. In a literature class you were told that theme is what the author is trying to convey, a central idea or meaning to the story. In rare exceptions, that might be true. In truth, authors have no idea what themes will manifest when they start a work. A few will pretend they had a grand design to start, but I never believed it.
I view my writing as an argument I am having with myself. I am not writing to satisfy a theme, but to find one. When I am satisfied with the argument, I know I have finished and I start editing and re-writing to strengthen the salient points.
The coronavirus pandemic makes writing without a theme difficult. Every word you write screams "you have missed the point. What about…" And that list is long, but familiar. The use of technology to control society, consumerism, the dangers of big government, individualism, and daily challenges our worldview are in every headline?
