Interactive Textbook

A Better Way

Traditional logic texts are too expensive, abstract, and boring. Students don't learn logic by reading pages of text; they learn logic from lots of practice and immediate feedback. This textbook takes a problem-solving approach, showing students the importance of logic to questions in philosophy, psychology, law, math, and computer science.

Saves money. Students shouldn't pay high prices for outdated software and passive instruction.

Saves hassle. Fully web based. No downloads or updates. Mobile integrated for daily practice.

Saves time. 100% computer-graded so you and your TAs can spend time on what matters: teaching.
