Cicero was a big fan of Plato and just like Plato he also wrote a book called The Laws, but whereas Plato's Laws was a very thick and philosophical volume, Cicero's version was much shorter and much more actually about literal laws.
I liked the first part the most where Cicero lays the foundation of jurisprudence on natural law. It's a very positive affirmation of the theistic worldview, and the implication being that without God society descends into nihilism. Nonetheless Cicero definitely lived in a godless era. Centuries before, Plato had complained in his own Laws that he lived in a godless era and now Rome was catching up. Simply take a look at Lucretius. There was no attempt however to really address the arguments of the materialists, skeptics, relativists, or any other critics of religion Cicero was inevitable surrounded by.
Cicero has a sublime, and philosophical view of divinity, but as not untypically among Platonists, he thinks the best manner of honoring God is by honoring the traditional gods. A whole chapter of the book, then is just legalism about Roman religion.
This is a dialogue, and the characters stay mostly in harmony until talking about the Roman constitution and legislative procedure. There's a little back and forth on the merits of the tribunate, on whether it was a benefit or an example of creeping mobocracy.
Many people appear to have had a rosy eyed view of aristocracy or monarchy, and believed that the good old days would have been maintained if the old institutions had been kept, not realizing that such a naive and stubborn view leads to civil war as it did throughout the history of Rome. Ah, but in the words of Quintus "it is better to be overwhelmed by force when defending a good cause than to acquiesce in a bad one."
This doesn't appear to be Cicero's view in this work. Marcus appears to be the one whose argument is meant to be more sympathetic. That in fact, the aristocracy is best fit to guide the nation, but without giving concessions to the people they won't be able to govern at all. There is also discussion on the balance of power, noting that even the aristocracy can go corrupt and then end up corrupting the entire nation.
This is basically a pamphlet. It's not very long, and hence the apparent low rating. I liked the idea here though, make no mistake. Nonetheless it's very legalistic and helps to already be familiar a bit with Roman institutions. I would've personally preferred more philosophy as was found in the first chapter.
