Logic 101

These lectures cover introductory sentential logic, a method used to draw inferences based off of an argument's premises. Logic is ubiquitous--individuals thinking of pursuing a career in law, computer science, mathematics, or social science must have a firm understanding of basic logic to succeed. Even someone who occasionally programs in Microsoft Excel would benefit greatly.

Lectures
  1. Welcome

    What are we doing here?

  2. Simple Sentences and Logical Operations

    Learn the language of logic.

  3. Truth Tables

    The algorithmic way of knowing when the truth value of simple sentences implies truth in more complex expressions.

  4. Replacement Rules

    Some complex statements are identical to simpler statements. Replacement rules teach you how to make these substitutions.

  5. Rules of Inference

    Knowing that two statements are true often allows us to draw new conclusions. Rules of inference ensure that those conclusions are valid.

Prerequisites

Logic 101 is the ground floor--there are no prerequisites other than being willing to think through problems.
