Wilson: "Do you think he was dead? Do you think those experiences were real?"
House: "Define real. They were real experiences. What they meant... Personally, I choose to believe that the white light people sometimes see, visions, this patient saw: they're all just chemical reactions that take place when the brain shuts down."
Foreman: "You choose to believe that?"
House: "There's no conclusive science. My choice has no practical relevance to my life, I choose the outcome I find more comforting."
Cameron: "You find it more comforting to believe that this is it?"
House: "I find it more comforting to believe that this isn't simply a test."
