“Only under extreme pressure can we change into that which it is in our most profound nature to become . . .

That is what people get wrong about transformation. We're not all shallow proteans, forever shifting shape. We're not science fiction. It's like when coal becomes diamond. It doesn't afterwards retain the possibility of change. Squeeze it as hard as you like, it won't turn into a rubber ball, or a Quattro Stagione pizza, or a self-portrait by Rembrandt. It's done.”
