Knowledge Level 2: Reasons, Luck and Doubt

Knowledge Level 1 said that to know something you need to believe it, it must be true, and you need good reasons. This course looks closer. A stopped clock can give you a true belief with good reasons, and you still don't know the time. Knowing how to ride a bike is a different kind of knowing, and some things you can know just by thinking. Then come the questions of how reasons rest on other reasons, how a new fact can take a reason away, why a missing sign can be a sign, and why a test that is usually right can still mislead you. You will see what to do when people you trust disagree, how a story changes as it is passed on, and how a group can close itself off from the world. Then more ways we fool ourselves - the first number we hear, what comes to mind easily, "I knew it all along" - and finally the biggest doubts - will the Sun rise tomorrow, do you know your own mind, and could your whole world be a dream? Everyday words, no maths and no symbols. It follows Knowledge Level 1, but you can start here.
