Facts

A Fact is a thing that is indisputably the case and is typically proven through evidence. If science, logic, and citation can prove something is true, then it gets labeled fact. If one or more parts of a statement are false, then it should be categorized a myth (all half-truths are myths). Some truth has grey areas, others like “Lincoln was a Republican” are a matter of record. You’ll find both types below, and when we use philosophical arguments that employ logic and reason, it will be noted.
