"The Fool"

In Tarot, the Fool represents an intuition beyond reason, a divine understanding of the inner workings of the world. He is unconcerned by the precipice above which he stands. He is often accompanied by a dog, representative of the distractions of the 'real' world, nipping at his heels.

It is easy to see the link between the figure of the Fool and Slothrop in Gravity's Rainbow.
