下文中，我们采用与 系统， 系统相同的方式， 来介绍命题逻辑（propositional logic）。. 命题逻辑，是在研究命题的证明和推理的过程中抽象出来的， 先不考虑语义，仅仅从符号的角度（形式化）来考虑它，则是更简单直接的。

Propositional logic studies the ways statements can interact with each other. It is important to remember that propositional logic does not really care about the content of the statements. For example, in terms of propositional logic, the claims, “if the moon is made of cheese then basketballs are round,” and “if spiders have eight legs then Sam walks with a limp” are exactly the same.

It is defined as a declarative sentence that is either True or False, but not both. The Truth Value of a proposition is True (denoted as T) if it is a true statement, and False (denoted as F) if it is a false statement. Semantics of propositional logic The meaning of a formula depends on: • The meaning of the propositional atoms (that occur in that formula) a declarative sentence is either true or false captured as an assignment of truth values (B = {T,F}) to the propositional atoms: a valuation v: P→ B Propositional logic is sometimes called “sentential logic” or “statement logic”, since it deals with logical relationships between statements taken as wholes. Propositional calculus is a branch of logic. It is also called propositional logic, statement logic, sentential calculus, sentential logic, or sometimes zeroth-order logic. It deals with propositions (which can be true or false) and relations between propositions, including the construction of arguments based on them.
