What in ourselves spreads to definability? Is it the seed the wind has gifted to us or the soil we have tilled? The crop we have tended from sprouting - watered and maintained? Is it the mere fact of the seed’s existence where it landed, or is the defining in our tending of it? Oh, the unnaturalness of our better humanity. What is planted as part of us will not remain without our effort, our choice to keep it so.
Our animal selves exist, but agency is something beyond them, across the border of instinct. Habits are not necessarily animalistic. They are planned in rows, deliberate. Yet after the first planting, they become perennials. Without the continued act of planting, does agency wane?
Our definition begins with choosing. Free agency and free will begin with an action. A will, to be defined as free, must first offer proof of this.
