Note 10 — Chapter 28
Reading edition
"The Chevalier d'Angos, a learned astronomer, carefully observed, for several days, a lizard with two heads, and assured himself that this lizard had two wills independent of each other, and possessing nearly equal power over the body, which was in one. When a piece of bread was presented to the animal, in such a manner that it could see it with one head only, that head wished to go towards the bread, while the other head wished the body to remain still."—Voltaire.
