Jeffrey Kaplan

A philosophy professor at UNC Greensboro who went looking online for videos that would help people understand hard problems like Russell's paradox, then decided to make his own. By spring 2025 his roughly hundred videos had passed 25 million views, which is remarkable for material this careful. Kaplan's gift is slowing a famous puzzle right down: he states the premises, shows where intuitions pull apart and lets you see exactly which step a critic would reject. Paradoxes are the highlight, with ethics and the philosophy of language close behind. Ideal if a textbook chapter has left you more confused than when you started.
