Maybe you've not yet heard about "Coursera". This is a series of courses available online and free to anyone who has a computer and the desire to learn.
An RSA member alerted us to this particular course: A Brief History of Humankind
To get an idea of what it will cover (including the history of religions), check out the short video on the website. Sounds fascinating!
We'd love to hear from anyone who does do the course, which starts on 11 August.
