What's the name of the 6th book of De Re Publica?

The sixth book of "De Re Publica," which is attributed to Cicero, is known as "Somnium Scipionis." This work is presented as a dialogue that occurs in a dream experienced by Scipio Aemilianus, in which he discusses various philosophical themes, including the nature of the cosmos, the afterlife, and the role of the soul. The dream serves as a vehicle for Cicero to express his views on the ideal state and the responsibilities of leaders.

In contrast, the other titles mentioned represent different works by Cicero and do not pertain to the sixth book of "De Re Publica." "De Divinatione" explores the concept of divination and its implications, "De Officiis" focuses on moral obligations and ethical conduct, while "De Natura Deorum" deals with the nature of the gods and the philosophy of religion. Each of these works contributes to Cicero's broader philosophical teachings but does not fall under the specific context of "De Re Publica."
