# The semantics of predicate logic Readings: Section 2.4, 2.5, 2.6. In this module, we will precisely deﬁne the semantic interpretation of formulas in our predicate logic. In propositional logic, every formula had a ﬁxed, ﬁnite number of models (interpretations); this is not the case in predicate logic. As a consequence, we must take more care

Function symbols: f(1),g(2). Predicate symbols: P(1),Q(2). Terms without variables: a, f(a). Formulas without variables: P(a), Q(a,b), (¬P(a)), (P(a)∨Q(a,b)).

[7]). How do we determine the Truth Value for formulas in Predicate Logic?

## 17 Oct 2008 The semantics of Predicate Logic does two things. It assigns a meaning to the individuals, predicates, and variables in the syntax.

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.

### A Study in Semantics and Modal Logic Quine's 'Methods of Logic' was written in analytical methods. Fuzzy thinking - new science of fuzzy logic systems of modal propositional logic right up to systems of modal predicate w ith identity.

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.

Contributors and Attributions
Syntax and Semantics Predicate logic is very expressive, but we need to clarify several important items. I First give a precise deﬁnition of what a formula in predicate logic is.

The metalanguage needed to capture inference patterns like (1) and (2) is called Predicate Logic. Its basic elements (entities) correspond to things in the world and their properties (predicates).
