Cicéron
True law is right reason in agreement with nature.
Misconceptions
Cicero was a Stoic.
He belongs to the New Academy, Plato's school turned sceptical: he looks for the probable and lets every school speak. He borrows a great deal from the Stoics in ethics, but he says so himself: "not as a translator", choosing what he takes. In On the Nature of the Gods, it is an Academic, Cotta, who takes the Stoic proofs apart.
"Summum ius, summa iniuria" (the height of law is the height of injustice) is a phrase coined by Cicero.
He quotes it as a proverb "already worn out" in his time. He uses it against those who respect the letter of a treaty to betray its spirit, like the general who plundered at night during a "thirty-day" truce.
In On the Nature of the Gods, Cicero proves that the gods do not exist.
The character Cotta refutes the Stoics' proofs, but he says he believes in the gods by tradition and only wants to show how obscure the question is. The last sentence of the book gives Cicero's view: Balbus, the defender of the gods and of Providence, seems to him closer to probability.
The printers' dummy text "Lorem ipsum" comes from Cicero.
Yes, but garbled: it comes from a passage of On Ends (I, 32), "neque porro quisquam est qui dolorem ipsum…", cut up and scrambled until it no longer means anything. This book is not yet in our corpus.
