Semantics for Classical Predicate Logic (Part I)∗ Hans Halvorson Formal logic begins with the assumption that the validity of an argu-ment depends only on its logical form, and not on its content. In particu-lar, if two arguments have the same logical form, then either they are both valid, or they are both invalid. But what is logical form?

Predicate Logic: Syntax and Semantics Propositional Logic, which we studied in the ﬁrst half of this book up to this point, is not rich enough by itself to represent many common logical statements.

Semantics for Predicate Logic: Part I Spring 2004 1 Interpretations A sentence of a formal language (e.g., the propositional calculus, or the predicate calculus) is neither true nor false.

For the In the semantics of propositional logic, we assigned a truth value to each atom. In predicate logic, the smallest unit to which we can assign a truth value is a predicate P(t 1;t 2;:::;t n) applied to terms.

PREDICATE LOGIC: SEMANTICS 164 cates with a di ff erent arity (for example, ‘ Fx,’ and ‘ Fxyz ’) then we shall assume that the model interprets the letter in di ff erent ways, one for each distinct use. In other words, we can safely assume that ‘ Fx ’ and ‘ Fxyz ’ are di … Semantics of Predicate Logic •In order to determine truth value of predicate logic formulae, the set of objects need to be selected. •Domain •A set of objects •Interpretation •Each constant is mapped to an element in •Each variable has any value in •Each function symbol us mapped to a function on •Each predicate symbol is mapped to a predicate on This is one of the things that symbolic logic was designed to do, and the task belongs to the realm of semantics.

The semantics of Predicate Logic does two things. It assigns a meaning to the individuals, predicates, and variables in the syntax. It also systematically determines the meaning of a proposition from the meaning of its constituent parts and the order in which those parts combine (Principle of Compositionality).

734 PREDICATE LOGIC “Interpretations” for expressions of predicate logic are possible meanings for the predicates and variables (Section 14.5). They are analogous to truth as-signments in propositional logic. Tautologies of predicate logic are expressions that are true for all interpreta-tions.
