Just like how it is impossible for me to read those two quotes without parts of my frontal lobe melting into a jelly.
I am very sorry, if the post makes you feel that way. But repetition does make it clearer to people, should they choose to actually read the other posts.
Which it seems only few does, considering the chosen words of some of the other posters.
"if a tree falls in a forest and noone is around to hear it does it make a sound?"
It depends entirely on what you define as sound. If you define the waves of air moving from the tree falling as sound, then it does make a sound, but if you define sound as waves of air making your inner ear move as sound, then it would in fact be soundless, should no one be around to hear it.
As air vibrations in general is not considered sound in themselves, the latter example seems to be the truth.
But, as mentioned, it depends on your definition of sound, rather than anything else.
"What is the sound of one hand clapping?"
Define clapping, for one, then determine whether the above is impossible or not.
One definition is that the palms come together to create sound, in which case it would be impossible for someone to clap with one hand, the the question is moot.
Another just mentioned coming together to create sound, which is actually possible for one hand to do, either fingers against palm or fingers against fingers. While both does create a sound, the former is not very distinct, while the latter actually can make a clap-like noise, if the person doing it is practices in smacking their fingers together with force.
So, either one hand clapping is impossible, in which case we don't need to speculate on sound, or it is possible, in which case you can try finding out what you would define the sound as, which, initially, should probably be clapping, seeing you are
clapping with one hand.
Which theoretically could also pose as an answer.
So, as far as I am concerned, only paradoxes are unanswerable in these respects, these questions just needs proper definition, a paradigm or a foothold in philosophy.
