Locke asked what happens if a prince's memories woke up in a cobbler's body

John Locke argued personal identity isn't about having the same body or soul, but the same continuous consciousness. To test the idea, he imagined a prince's memories transferred into a cobbler's body: most people's instinct is that the 'prince' has survived, memories intact, wherever his body ended up.
