De Officiis

philosophy religion Maturity 11-13 Next article →

Have you ever wondered how to be a truly good person? A famous Roman thinker named Marcus Tullius Cicero spent much of his life exploring these questions. In 44 BC, he wrote a special book called *De Officiis*. This title can mean "On Duties" or "On Moral Responsibilities." It was written as a long letter to his son, Cicero Minor. His son was studying philosophy in Athens at the time. Cicero wanted to share his best ideas on how to behave. He hoped to guide his son toward a life of wisdom.

The book is divided into three distinct parts. The first part looks at what is honorable in itself. Cicero believed being good comes from four main things: truth, justice, bravery, and politeness. The second part discusses what is helpful for a person's own life. It looks at how people gain wealth or power through fair ways. The third part is about making very hard choices. Sometimes, doing the right thing seems to go against what helps you. Cicero argued that being good and being successful are actually the same thing. You should never choose private gain over being a virtuous person.

Cicero wrote this work in a very short amount of time. He finished it in under four weeks during October and November of 44 BC. At this time, he was 62 years old. He was also very busy with politics in the Roman Republic. He was trying to stop revolutionary groups from taking control. Sadly, this was the last year of his life. He was killed shortly after the assassination of Julius Caesar. Even though he wrote it quickly, the book is very deep. It uses many stories from history to explain its points.

Many different thinkers have used this book for hundreds of years. It was even used by leaders in the Christian Church. Famous people like St. Augustine and St. Thomas Aquinas studied it. There are about 700 old handwritten copies still in libraries today. After the printing press was invented, it was only the third book ever printed. It was very important to leaders like Henry VIII.

A young Henry VIII even had a copy that said "Thys boke is myne." This shows how much people valued his words.

Cicero's ideas have traveled all over the world. In 1437, a prince translated the book into Portuguese. Later, the famous thinker Erasmus published his own version in Paris. Even the writer Voltaire said no one would ever write anything wiser. The book has influenced many famous laws and ways of thinking. It even appears on a memorial in Washington, D.C. today. People still read *De Officiis* to learn about Roman life. It remains a powerful guide for how to act in the world.
