Religious Studies KS3 & KS4/GCSE: How can we know the world exists?

Have you ever thought about the big questions?

Two friends discuss whether the world really exists, or whether they are just brains in jars, and if it really matters or not.

Introducing Scottish Enlightenment philosopher David Hume and the problem of perception and reality.

This clip is from the series Enlighten Up!

Teacher Notes

Students can have a debate on the question.

Half the class has to argue why they could be a brain in a jar, and the other half has to argue that they are real people in a real world.

Students could get in groups and prepare the main points to make first, and who will make them, before the debate begins.

Afterwards, they can write a summary of the debate and include an explanation of why the real answer is probably unknowable.

Curriculum Notes

This clip will be relevant to teaching Religious Studies at KS3 and KS4/GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland.
