Single Idea 2254

[catalogued under 13. Knowledge Criteria / D. Scepticism / 4. Demon Scepticism]

Full Idea

I will suppose an evil genius, supremely powerful and clever, who has directed his entire effort at deceiving me. I will regard all external things as devilish hoaxes, and myself as not possessed of a body or senses, but falsely believing these things.

Gist of Idea

To achieve full scepticism, I imagine a devil who deceives me about the external world and my own body and senses
