Courses

Complete college-level courses. One idea at a time. Free.

Every course here covers the same ground as its university equivalent, broken into numbered micro-videos — most of them twenty seconds long. Every video is one idea. Every idea has a number, and every number knows what comes before it, so you can start anywhere and always find your way back to solid ground.

Why it’s built this way

Students don’t fail courses. They fall behind them.

Six years in the classroom taught me one thing above everything else: students fall behind one missed prerequisite at a time, until nothing downstream makes sense and there’s no visible way back. A lecture course can’t fix that, because the dependencies are invisible. These courses are built so they can’t be — every idea is one numbered video, and every number knows exactly which numbers come before it.

These aren’t highlight reels. Each course is the whole map: every claim checked against scholarly references and standard texts, with the full source list published for anyone to inspect. The courses are free and stay free.

Who makes this

A curriculum with an author.

I’m Justin Ryan Carver. I spent six years as an adjunct professor of philosophy at a community college, teaching Introduction to Logic, Introduction to Philosophy, and Introduction to Ethics and Values. I also hold an Education Specialist degree in Educational Leadership, a Master of Arts in Liberal Studies, and Project Management Professional certification.

The résumé isn’t the point, though — every claim in every course is mapped to published sources you can check yourself. Trust the receipts as much as the teacher.
