Finding them beyond his grasp, but refusing to admit failure, the fox declares the grapes to be inedible and turns away. A hungry fox tries to reach a bunch of grapes dangling from a vine. ![]() Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime Sean Carroll Oneworld (2019)Īt the beginning of Something Deeply Hidden, Sean Carroll cites the tale of the fox and the grapes from Aesop’s Fables.
