I began to wonder whether anything truly existed, whether reality wasn't an unformed and gelatinous substance only half-captured by my senses....If that were true, each of us was living in absolute isolation. The thought terrified me. I was consoled by the idea that I could take that gelatin and mold it to create anything I wanted...At times I felt that the universe fabricated from the power of the imagination had stronger and more lasting contours than the blurred realm of the flesh-and-blood creatures around me.
