By deﬁnition, an interpretation ofasentenceofaformallanguageisaspeciﬁcationofenoughinformation to determine whether that sentence is true or false. 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 Relative to the semantics of propositional logic, there are two main sources of complexity. (i) First, in predicate logic atomic formulas are treated as compound ex- pressions, whereas in propositional logic they were unanalyzed primi- tives. What does this mean?

## On the Semantics of Logical and Metaphysical Necessity

Its basic elements (entities) correspond to things in the world and their properties (predicates). Predicate Logic is an extension of Propositional Logic not a replacement.

Solution: Here, the object is Lipton. It will be represented as Tea In mathematical logic, predicate functor logic (PFL) is one of several ways to express first-order logic (also known as predicate logic) by purely algebraic means, i.e., without quantified variables. PFL employs a small number of algebraic devices called predicate functors (or predicate modifiers) that operate on terms to yield terms. PFL is mostly the invention of the logician and philosopher Willard Quine. 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. Same as with programming languages: we have to pin down the syntax exactly.

### Formal Logic, Models, Reality - Yumpu

1 Syntax Propositional Logic was created to reason about Boolean objects; therefore, every formula represents (that is, when we endow it with semantics) a Boolean statement.
