## Overview

Philosophy 254: Symbolic Logic is an introduction to reasoning in formal symbolic logic. We will cover the syntax and semantics of classical sentential and predicate logic, translation of English sentences into symbolic form, and procedures for evaluating sentences and arguments, principally natural deduction.

• Symbolize English sentences and arguments using symbolic notation
• Use truth tables to evaluate for formal logical properties such as entailment and consistency
• Construct derivations to show that arguments in sentential and predicate logic are valid
• Construct interpretations for predicate logic to demonstrate properties such as consistency and invalidity
