There is this anecdote about one of the ancient skeptics (Pyrrho, Sextus Empiricus? How can one remember not to forget all those names in the long run?) who reportedly went for a walk with one of his pupils.
What is so momentous about the general mnemonic mementos in The Discovery of Heaven, then?
So I keep asking myself, what can I actually write about the novel that would reveal as little as possible about its matter?
