Power is all about having control, mostly over others, but also over things and circumstances. Powerlessness is all about having no control over something, including being under something’s complete control. So for anyone with power who is unable to share it to any meaningful extent, I ask do they have power, or does power have them?
It’s generally accepted that knowledge is power. But is it, really? What if you knew something, but did nothing with it? Did you wield any more power than someone who did nothing because they didn’t know what you knew? What good was your power if you didn’t do anything with it? What good would superheroes be if they did nothing with their superpowers?
