Interesting Facts

In philosophy, the concept fact is considered in epistemology and ontology. Questions of objectivity and truth are closely associated with questions of fact. A "fact" can be defined as something which is the case, that is, the state of affairs reported by a true proposition.
Facts may be understood as that which makes a true sentence true. Facts may also be understood as those things to which a true sentence refers. The statement "Jupiter is the largest planet in the solar system" is about the fact Jupiter is the largest planet in the solar system.
Misunderstanding of the difference between fact and theory sometimes leads to fallacy in rhetoric, in which one person will say his or her claim is factual whereas the opponent's claim is just theory. Such statements indicate confusion as to the meanings of both words, suggesting the speaker believes that fact means "truth," and theory means "speculation."
