Quizzes
Harry Gensler's site has a long quiz about the Golden Rule. It applies to Jesus' command to 'Love your neighbour as yourself', but is also really a form of Kant's Categorical Imperative. The GR prevents us acting inconsistently. The test was long, and it's easy to get questions wrong (I gave up about half way through, and I had already got 5 wrong). However, it's a great way to learn about the Golden Rule.
