< If a tree falls in the woods and no one is there to hear it, can we say that sound exists or not>

It exists because we have no reason to believe the principles of sound stop when they aren't observed. I could make an experiment that is sensitive to trees dropping in the woods when no one is around and I can INFER that because it goes off when trees are being listened to, and that it goes off when we come back and find trees down, that it exists. But is not perceived by he who is absent. Lots of other things in the forest know, though.

I also amused myself by learning to clap one hand and thinking about things I'm not thinking about.
