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

Are you just a brain in a jar? Introducing philosopher David Hume and the question of the perception of reality, two friends discuss how they can be sure the world exists.

Written and performed by the Burnistoun team of Robert Florence and Iain Connell.

This short film is from the BBC series, Enlighten Up!

Teacher Notes

You could lead a class debate on this question.

Half the class could argue for why they could be a brain in a jar, and the other half could 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 could write a summary of the debate and include an explanation of why the real answer is probably unknowable.

Curriculum Notes

This short film will be useful for teaching secondary PSHE and religious studies.
