“Once I thought this question: “Do I own my name?” I do not mean my slave names. My slave names change at the whims of my masters. […] My true name I tell nobody, so nobody can steal my name. The answer, I think, is yes - my true name is a thing I own. Sometimes another thought comes to me: “Do I own my memories?” The memory of my brother diving from the turtle rock, sleek and brave…[…] Yes - like my true name, my memories are things I own.
Once I thought this thought: “Do I own this thought?” The answer was hidden in mist, so I asked Dr. Marinus’s servant, Eelattu. Eelattu answered, yes, my thoughts are born in my mind, so they are mine. Eelattu said that I can own my mind, if I choose. I said “Even a slave?” Eelattu said, yes, if the mind is a strong place. […] Master Fischer owns my body, then, but he does not own my mind. This, I know, because of a test. When I shave Master Fischer, I imagine slitting open his throat. If he owned my mind, he would see this evil thought. But instead of punishing me, he just sits there with his eyes shut.
