if a tree falls

Surely you don’t mean that you need chemicals to function properly.

If Helen Keller fell in a forest…

Eh. I got nothin’.

If a tree falls in the forest, and lands on an existentialist, would anyone care?

Does the Pope shit in the woods?

If D.B. Cooper falls in a forest, and no one is there to meet him, what happens to all the money?

I always wondered about this myself. I’ve heard it attributed to Aquinas, but I believe that’s erroneous. According to this source:

I’ve found another source which kind of attributes the question to Berkeley. I suppose if one concludes that Berkeley is at least responsible for the question’s modern popularity, the next question would be: did he in fact originate the example?

In case anyone’s wondering about the “one hand clapping” issue, I believe this has a definitive answer.

What do you mean no one? There’s always *someone * around to hear it, birds, chipmunks, etc.
