The problem you guys are having here is that you are confusing sound waves and sound. A sound wave is, in terms of physics, a longitudinal(?) wave that causes compression in patterns that our ears can perceive as sound.
There are three mediums through which longitudinal waves can be commonly observed.
- Air. Sound waves that we perceive as sound, are most often made by compressing the air with some sort of vibration.
- Water. The same idea here, it's just a different medium. The waves travel faster in water than they do in air.
- Earth. There are actually longitudinal waves in the ground, too!
What these waves "are" depends on how you perceive them. You cannot perceive them in air with anything except your ears; thus they are perceived as sound. You can perceive them in water with your ears (if you're under the water), or under some circumstances they appear along the surface as latitudinal waves that we call... 'waves', since we perceive them with our eyes.
You can't perceive them appropriately with your ears when they are passing through earth, though. When they are sufficiently strong, we can perceive them visually, however. This is a phenomenon known as an earthquake.
Sound waves are the same thing as the waves that produce earthquakes - just in a different medium.
But earthquakes are definitely not sound.
Therefore you can't simply equate sound and sound waves. Something has to turn those waves into sound. That something is your ear, and if it's not there, there is no sound.
Great post.

Of course it isn't a profound point. It's not my point either- I quoted Epicurus in the very first response.
Pretentious banter? It's just irritating seeing people slip from trying to argue against the stance of the OP, and then reduce their argument to saying it isn't practical, and still further, eventually merely discounting philosophical pursuits, or merely saying that an ancient view is not applicable, even if it is right.
People say sound when it's short for sound wave. This thought exercise is merely trying to get everyone to recognize that. The tree makes no sound, and to think it does is to hold an illogical thought. It's not pretentious banter to consistently re-iterate a point and become baffled and annoyed when people's arguments devolve and eventually downgrade into insults about the material (hi sillypuddybuddy).
Was I being condescending? Probably- I think I am better than others because of my drive for knowledge and understanding. I think it's both a good and an important attribute to have, and those who lack it lack something that would otherwise make them better. I have that better quality, and so forth. I look down on anyone who dismisses philosophy. I think they are ignorant or stupid, or both. As for thinking I know more than other people because I know the fact that the tree makes no sound is ridiculous. I don't think that, but maybe you think you know more than me and can make that assumption about how I compare myself to others in that respect.
This topic is important because it provides an insight into what our natural world is, how we understand what the world is, how we interact with it, what our limitations with our understanding are, and I think it gives us a kind of empowerment. Just recognizing that I have a special adaptation which allows me to translate certain vibrations in my ear into something integrated with my conscious experience is an amazing thing and makes one appreciate the senses more.

IDK, I agree that it’s largely meaningless in a MODERN context. However I see it as entirely likely that the ancient philosophers could have used and example like this as a teaching moment. The question is a thought exercise. It’s like Mind Candy. You make your mind work around the question given the logical constraints your worldview entailed and come up with an answer … and those guys would make you back it up with logic too. Even today it’s somewhat useful as a way to put your mind in a particular … what’s the word? Paradigm? … and work out an answer using artificial rules. That’s not a bad thing, unless, like real candy that’s all you gave your mind.
The problem is that modern thinking pretty much renders this particular question moot for most people. We know what sound is and define it in an entirely different way than the ancients would have. The question about God was much more meaningful to modern thinkers in that respect.
Not all modern philosophy is useless either. Logic for instance is very valuable. However there is a movement to separate that out from Philosophy too. If that happens then IDK what’s really going to be left that’s of practical value. The history of Philosophy is still important and will remain so. I see this as a nice area to study, especially for self growth. Not everything in life has to be practical.
It just irks me when someone asks a question … and then insists that some obscure classical way of thinking is the only way to approach things and that anyone using a more modern understanding is wrong.
Well, it is wrong. It's a category mistake. Ascribing properties to a thing which can't possibly have such qualities. There's no other way to say it or get around it. You bite the bullet and admit that many people use the term sound when they should say sound wave/wave/whatever. Is this distinction supposed to be groundbreaking? No- but it is a separation, and that is a new way of understanding. It's important to have that.
I can function perfectly well saying sound, which can be short for sound wave. My having knowledge of what I am actually referring to is a
good thing, though, and something worth pressing in this thread.
