Fact

philosophy religion Maturity 13-18 Next article →

A fact is a piece of true information about the real world. It describes a thing that has happened or a way things are. Facts are special because they do not depend on what people believe. You can have an opinion, but a fact stays the same. For example, the statement "the Sun is a star" is an astronomical fact. Another example is a linguistic fact, like saying a sentence contains words.

Even history uses facts, such as knowing Abraham Lincoln was the 16th president of the United States. Some people even say he was assassinated, which is also a historical fact.

There are different ways to find and check if something is a fact. Scientists use a special way of working called the scientific method. They use careful observations or measurements to find facts. These results come from experiments that other people can repeat to see if they get the same answer. This makes scientific facts very reliable.

People can also use reason or personal experience to check things. Some people look to authority or standard reference works to find the truth. In math, a fact is a statement called a theorem. A theorem is proven using logical arguments and specific rules called axioms.

People have been thinking about the meaning of "fact" for a long time. The word comes from the Latin word "factum." In the 1500s, it meant a thing that was done or performed. By the mid-16th century, people started using it to mean something that really occurred.

In 1870, a thinker named Charles Sanders Peirce wrote about how people decide what to believe. He described four methods: tenacity, authority, a priori, and the scientific method. Later, in 1729, the word began to be used to describe an allegation that might or might not be true. This shows how our language changes over many years.

Philosophers study facts in branches called epistemology and ontology. Epistemology is the study of knowledge and truth. Ontology is the study of existence and reality. Some thinkers believe a fact is a "state of affairs." This means a fact is just a way that things are in the world.

Others say a fact is what makes a sentence true. For example, the sentence "Jupiter is the largest planet" is true because of a real fact about Jupiter. There are even complex facts. The fact that Paris is the capital of France involves many smaller parts like the city, the country, and the government.

It is important to know the difference between facts and other ideas. Facts are different from theories, which are used to explain why facts happen. They are also different from values, which are ideas about what is good or bad. A philosopher named David Hume noted that you cannot always get a value from a fact. For instance, knowing people need food is a fact, but saying it is "good" to give food is a value.

Historians also use facts to understand the past. Some say it is hard to be perfectly objective because people have biases. Historians try to have a fair conversation with the past by gathering as many facts as they can.
