[[Person is on the phone.]] Person: Hello? 911? I'm trapped! Person: It's dark and I can't see anything except these two distorted splotches of light! Person: Help! [[The 911 operator is in an office, wearing a headset.]] Operator: Splotches of light? Your ... eyeballs? Person (over phone): I think that's what they are! There's meat everywhere! Operator: ... so you're a brain. Person (over phone): Yes! Operator: Yeah, we all are. You're not trapped. Use your body to walk around and experience reality. Person: But everything's just signals in my sensory cortices! How can I be sure they correspond to an external world?! Operator (over phone): I'm sorry, but we can't send a search-and-rescue team into Plato's cave. {{Title text: Socrates could've saved himself a lot of trouble if he'd just brought a flashlight, tranquilizer gun, and a bunch of rescue harnesses.}}
