WebFirst Order Logic (FOL) is a mathematical knowledge representation language used to describe logical concepts and relationships. FOL has many applications. The motivations for using FOL are the unambiguous representation of concepts and the representation of reasoning (how an argument can be represented as a FOL proof).
