Knowledge Level 1: How Do We Know?

How do you know? You know your own name, the way home, that the Earth is round, and that the shop opens at nine - but how? This course is about the difference between knowing something and only believing it. It is for anyone, with no maths and no symbols. Short lessons start with what a belief is and why a lucky guess is not knowledge, then look at where knowledge comes from - your senses, your memory, what other people tell you, and working things out - and at evidence, and how sure it lets you be. Then come the questions of whom to trust, the ways we fool ourselves, and doubt done well - saying "I don't know", and changing your mind when the evidence changes. It follows Logic Level 1, but you can start here. You need only a notebook and the world around you.
