A logical argument is one that relies on the principles of classical logic to establish veracity. An excellent example is this classic: If A = B and B = C, then A = C.

Logic forms are simple, first-order logic knowledge representations of natural language sentences formed by the conjunction of concept predicates related through shared arguments. Each noun, verb, adjective, adverb, pronoun, preposition and conjunction generates a predicate.

A statement form (or propositional form, or logical form) is an expression made up of statement variables, called compo- nent statements, (such as p, q, and r), and logical connectives (such as ∼, ∨ and ∧) that becomes a statement when actual statements are substituted for the component statement variables.

1) If the conclusion of an argument is true, then it must be sound. 2) If all the premises of an argument are true, then it must be valid. 3) An argument is valid when and only when its premises are true and its conclusion is true. 4) A sound argument is both valid and has all true premises.

The logical form of an argument is composed from the logical forms of its component statements or sentences. These logical forms are especially helpful for assessing the validity of deductive arguments.
