A young woman came across a man at a railway station, standing confused on the platform.
She lit up, "Hey I know you! You're that famous philosopher!
"I read about you! Aren't you a hero? Or something else? Not a villain? I don't remember."
He looked surprised, "Why ask me? I might be lying."
Right, he was a Philosopher! Thinking fast, she replied carefully "If I asked you if you were a liar, what would you say?"
"I'd lie!"
"So you are a villain!" Triumphant!
He shook his head.
"Depends on who you ask. My wife is mad about how I killed her mother and all. Never says a thing about the five people I saved from that runaway trolley! Still get Christmas cards from four of them."
"So you don't know that you're a hero?"
"I am, but I don't know if I am. If that makes any sense?"
She shook her head, No.
"It did when you said it!"
Moving on, she asked "Who else did you save?"
"A dozen people in the hospital! Waiting for organ transplants! I took a hobo in there; they used his parts to save twelve others."
"Was he dead?"
"Not at first."
Concerned now, she thought carefully.
"Do people always have to die, when you save someone?"
He nodded, that was apparently a good question.
"I wonder about that. Went to save a murderer on the railroad tracks last week, left my cat in my suitcase, at the lost-luggage office. Should be fine when I return."
"Won't it be dead?"
"We'll see, kid, we'll see."
