John Locke's Question

JOHN LOCKE'S QUESTION

If a tree falls in the forrest
and there is no one there to hear it
is there a sound, asked John Locke

For a while I thought the answer is
obvious. Of course, there is a sound
even in the middle of woods

But then it dawned on me that my dogs return
when I blow a whistle yet hear nothing

So, I started to question the obvious:
for sure the earth moves and air vibrates
I thought, but is it the same as the sound?

But if the sound depends
on our ears and the ability to hear
then what about the movement?

Does the earth moves when our minds move?
Does it stop when our minds stop to run?
