A premise is a statement that an argument claims will induce or justify a conclusion. In other words: a premise is an assumption that something is true. In logic, an argument requires a set of two declarative sentences (or "propositions") known as the premises along with another declarative sentence (or "proposition") known as the conclusion. This structure of two premises and one conclusion forms the basic argumentative structure. More complex arguments can utilize a series of rules to connect several premises to one conclusion, or to derive a number of conclusions from the original premises which then act as premises for additional conclusions. An example of this is the use of the rules of inference found within symbolic logic.
