Higher-order logic And again we are limited because first-order logic can apply quantifiers only to atomic values. But in real life our complex definitions are based on another ones and those are

in first order logic, i know the rules. However, whenever i convert some sentences into FOL, i get errors, I read many books and tutorials, do u have any tricks that can help me out, However, whenever i convert some sentences into FOL, i get errors, I read many books and tutorials, do u …... In set-theoretic terms, a first-order logic quantifies over individuals, while a second-order logic quantifies over sets of individuals. Viewed this way, a predicate is identical to the set of individuals that it applies to. You can make higher-order logics by using metatypes, quantifying over sets of predicates. This kind of logic can be used to define type systems for predicate logics

**Chapter 4 The World According to Predicate Logic**

The conditions for truth of logical sentences in First-Order Logic are analogous to those for the truth of logical sentences in Propositional Logic. A negation ¬? is true if and only if ? is false. A conjunction (? ? ?) is true if and only if both ? and ? are true. A disjunction (? ? ?) is true if and only if ? is true or ? is true (or both). An implication is true unless the... I am wondering how one would go about constructing a "only one" statement using first order logic. I stumbled into an example that said "Only one student took Greek in Spring of 2011." I can easily construct something like "There is a student who took Greek in Spring of 2011."

The fact that there is [Burris p___] "no good set of axioms and rules for higher order logic" is frustrating not only in that it stumps the desire to write common sense mathematically, but also because operations which seem natural for electronic commerce seem at first sight to demand higher order logic.

- However, some texts of mathematical logic (particularly those on first-order logic, rather than propositional logic) make a distinction between these, in which the first, -, is used as a symbol in logic formulas, while ? is used in reasoning about those logic formulas (e.g., in metalogic).
- In other words, First-Order Logic is an abstract language that in one particular case is the language of Group Theory, and in another case is the language of Set Theory.
