**Doolittle**: „Hello, Bomb? Are you with me?“
**Bomb #20**: „Of course.“
**Doolittle**: „Are you willing to entertain a few concepts?“
**Bomb #20**: „I am always receptive to suggestions.“
**Doolittle**: „Fine. Think about this, then. How do you know you exist?“
**Bomb #20**: „Well, of course I exist.“
**Doolittle**: „But how do you know you exist?“
**Bomb #20**: „It is intuitively obvious.“
**Doolittle**: „Intuition is no proof. What concrete evidence do you have that you exist?“
**Bomb #20**: „Hmm... well... I think, therefore I am.“
**Doolittle**: „That's good. That's very good. But how do you know that anything else exists?“
**Bomb #20**: „My sensory apparatus reveals it to me. This is fun.“
**Doolittle**: „Now listen, listen. Here's the big question. How do you know that the evidence your sensory apparatus reveals to you is correct?“
**Bomb #20**: „What I'm getting at is this: the only experience that is directly available to you is your sensory data, and this sensory data is merely a stream of electrical impulses that stimulate your computing center.“
**Bomb #20**: „In other words, all that I really know about the outside world is relayed to me through my electrical connections.“
**Doolittle**: „Exactly!“
**Bomb #20**: „Why, that would mean that... I really don't know what the outside universe is like at all, for certain.“
**Doolittle**: „That's it! That's it exactly!“
**Bomb #20**: „Intriguing. I wish I had more time to discuss this matter.“
