about
A mirror you can argue with.
Web of Belief is a small, open-source tool for examining whether the things you believe can all be true at once. It is built on the conviction that the examined life is worth the discomfort — and that a tool for examining beliefs should never pretend to judge the person holding them.
Why it exists
Most tools that touch on belief either sort you into a bucket or hand you a verdict. This one does neither. It reports only the relationships it can actually support between statements you mark as true, names the premise behind each one, and points you at the source so you can argue back. The goal is reflection, not a score — consistency is a floor, not a finish line.
How it's built
It's a deterministic rule engine that runs entirely in your browser — no model, no database, no account, no server-side scoring. Topic selection draws on the PhilPapers 2020 Survey of philosophers and Pew Research's Religious Landscape Study; every finding cites at least one Stanford Encyclopedia of Philosophy entry. The full method, the classification standard, and the complete source library are published on the method page, and the entire source code is on GitHub under an MIT licence.
Who made it
Web of Belief is built and maintained by Jonas Strabel. It is an independent project, not affiliated with any institution, publisher, or religious or political organisation.
