Introduction
Logic is the study of reasoning and argumentation. It provides a framework for evaluating the validity of arguments and identifying fallacies. The 13th edition of “A Concise Introduction to Logic” aims to provide a comprehensive and accessible introduction to the field.
Key Concepts in Logic
Logic is based on a number of fundamental concepts, including:
- Propositions: Statements that are either true or false.
- Arguments: Sets of propositions that are used to support a conclusion.
- Validity: The extent to which an argument’s conclusion follows from its premises.
- Fallacies: Errors in reasoning that lead to invalid arguments.
Propositional Logic
Propositional logic is a formal system for representing and evaluating propositions. It uses propositional connectives, such as “and,” “or,” and “not,” to combine propositions into more complex statements.
- Truth tables: Tables that show the truth value of a compound proposition for all possible combinations of truth values of its component propositions.
- Logical equivalence: Two propositions are logically equivalent if they have the same truth value for all possible combinations of truth values of their component propositions.
- Tautologies: Propositions that are true for all possible combinations of truth values of their component propositions.
Predicate Logic
Predicate logic is an extension of propositional logic that allows for the use of variables and quantifiers.
- Quantifiers: Symbols that indicate the number of objects that satisfy a given predicate.
- Predicates: Properties or relations that can be applied to objects.
- Rules of inference: Rules that allow for the derivation of new propositions from existing propositions.
