“Where mathematics was a magnificent imaginary building, the world of story as represented by Dickens was like a deep, magical forest for Tengo. When mathematics stretched infinitely upward toward the heavens, the forest spread out beneath his gaze in silence, its dark, sturdy roots stretching deep into the earth. In the forest there were no maps, no numbered doorways.... Tengo began deliberately to put some distance between himself and the world of mathematics, and instead the forest of story began to exert a stronger pull on his heart... Someday he might be able to decipher the spell. That possibility would gently warm his heart from within.”

“Of course, reading novels was just another form of escape. As soon as he closed their pages he had to come back to the real world. But at some point Tengo noticed that returning to reality from the world of a novel was not as devastating a blow as returning from the world of mathematics. Why should that have been? After much deep thought, he reached a conclusion. No matter how clear the relationships of things might become in the forest of story, there was never a clear-cut solution. That was how it differed from math. The role of a story was, in the broadest terms, to transpose a single problem into another form. Depending on the nature and direction of the problem, a solution could be suggested in the narrative. Tengo would return to the real world with that suggestion in hand. It was like a piece of paper bearing the indecipherable text of a magic spell. At times it lacked coherence and served no immediate practical purpose. But it would contain a possibility. Someday he might be able to decipher the spell. That possibility would gently warm his heart from within.”

“He wished that the mathematics of the world were like the mathematics of the heart - then his equal love and hate would mean he felt nothing instead of double.”

“Deep in the forest a call was sounding, and as often as he heard this call, mysteriously thrilling and luring, he felt compelled to turn his back upon the fire and the beaten earth around it, and to plunge into the forest, and on and on, he knew not where or why; nor did he wonder where or why, the call sounding imperiously, deep in the forest.”
