Suppose you took a book – any one of those on your shelf – and it took up into the dome of your imagination. Then, having it laid on the operating table, you change the font of its title. Next, you invert the colors, or if you can’t figure an inversion, then change them into another that is starkly different. Next, you compress the book to so thin a width that it might as well be a sheet of paper. Then, you curve the squared edges and it becomes a circle. Then, you multiply its dimensions till it dangles like a loose spring. And finally, as if these operations were not drastic enough, you morph the mangled object into an elephant. Now, the question is: is it still a book?
