Why this exists
I grew up taking people at their word when they claimed their reading of a text came straight from God. What I couldn't do, back then, was tell a careful argument from a confident one. They sounded the same to me.
Formal logic changed that. Once I learned to separate the shape of an argument from the feeling of it, I could finally ask whether a claim actually followed from its evidence — or whether I was just being walked down a persuasive path. That's still the most useful thing anyone has ever taught me. I am still a person of faith. I am also no longer easy to manipulate.
I built Rigorous Reasoning because I wanted my students, and anyone else who'd benefit, to get there faster than I did. Not as an anti-religion tool — as a clear-thinking tool. The same skills work on a politician's promise, a financial pitch, a medical claim, or your own self-talk at 2am.
What makes this different
A lot of platforms cover logic somewhere. Rigorous Reasoning only covers logic. Every unit, every activity, every feedback loop is aimed at one thing: getting you to notice when reasoning is working and when it isn't. That focus is the product.
You'll find 8 reasoning domains, hundreds of activities with instant written feedback, spaced-repetition review, an adaptive recommendation engine, and an instructor track for classroom use. You won't find math worksheets, vocabulary drills, or course recommendations in fields we don't cover. That's on purpose.
