"Thought. Thought: that field of force still to be analysed. Thought: as inseparable from a higher being as gravity from a planet. It wraps around me, as my senses go about their endless job of turning all the external world into symbols. I can know no external thing without its being touched - perhaps in some unguessable way transmuted - by my thought. The baseness I saw my own people, the nuls, perpetrating on that world Earth; was it real, or a misinterpretation in my mind?"
