In America you are expected to be in charge of yourself, a sovereign individual, the supreme authority within the sphere you occupy. It’s as unruly a kingdom as there ever was, what with the automaticity of your blood and guts immediacy and your subjective or ego-function’s (effective or not) response to the stimulation it provides. Sure, it’s not inconceivable that someday there’d be a pill or an injection that corrals and manages those feisty neurons, but in the meantime, it’s up to you.
Of course, our nation also has more in mind for your sovereignty than your personal fulfillment. The promise of achieving our nation depends on your sovereign behavior including your enlightened self-possession. Here, “self” represents you, the sovereign individual, and “possession” represents your behaviorally realized command of your sovereignty.
