The Open Logic Project collects teaching materials and resources about logic.
About Open Logic Project
The Open Logic Project collects teaching materials on mathematical logic for a non-mathematical audience, intended for advanced logic courses as taught in many philosophy departments. Its main product is the Open Logic Text, a collaborative textbook of logic and formal methods that starts at an intermediate level. The materials are published under a CC-BY license, and the LaTeX source code and PDFs can be downloaded. The project is written with configurability in mind, so users are free to change the materials and share their changes.
Key features
- Downloadable LaTeX source code and PDFs of the text
- CC-BY license permits modification and redistribution of the materials
- Written with configurability in mind for adapting to different courses
- Collaborative development on GitHub, with contributions and feedback welcome
- Authored and edited by an international team of logicians
- Starts at an intermediate level for non-mathematical audiences
Best for: Instructors and departments teaching advanced logic courses, especially in philosophy, who want adaptable open teaching materials.
