Sound as touch, more on the science of sound. The 2 minutes starting at 4:40 describe the sequence of events involved between vibrations in a medium (for humans, the medium is typically air) reaching an ear, and being consciously aware of hearing. Where on the path described is "sound"? Might there be a type of tree that falls to the ground imperceptibly? According to the OP clearly the answer is no, obviously a falling tree will make a noise, just as it was once obvious to Europeans that all swans were white, (or not). Could there be a problem relying on inductive reasoning when predicting outcomes with certainty (if there is, it might take a philosopher to help us understand the problem, and provide possible means to avoid it). Here's a, possibly, interesting probability, if you completed school more than 45 years ago, half the facts you were taught have probably since been shown to be not facts after all (source). That probability has been fairly constant for the more than 300 years the Royal Society has been in existence. What, if anything, does this probability tell a person about what he or she "knows". I think you'll find it's a bit more complicated than that ... |

The 2 minutes starting at 4:40 describe the sequence of events involved between vibrations in a medium (for humans, the medium is typically air) reaching an ear, and being consciously aware of hearing. Where on the path described is "sound"? That idea of facts is a bit false isn't it, because if you were told, "These are the 10 largest cities in the US" in 1962 then that fact is still true even if today half of those cities are no longer in the list. With only a little thought one should be able to see that a lot of facts just need annotating with a date/time stamp, and then they will always remain true even if they are later superseded at a later date:time. So no 50% of the facts taught 45 years ago were not false, it's just that things have progressed. |

Where on the path described is "sound"? You are quite right, the 10 largest cities is clearly a fact with details that change over time. Are you suggesting that all facts are similarly dependent on context? If so, what might this tell a person about what he or she "knows"? If not, how does a person distinguish between facts that are true only within a particular context and those that are always true? I think you'll find it's a bit more complicated than that ... |

Before we can convince you otherwise about your debunking, you must first debunk something. If you have debunked anything in this thread, can you please indicate where? Is there a race? If so, you appear to be winning. Not falling for that old one, of batting the ball back and trying to make someone re-justify their original assertions twice. Sorry, been around too long. I don't have to justify myself, I have already done that, unfortunate for you if you can't see it, or disagree. So come on convince me of your views if you dare. Surely you can post a link to an earlier post, here's one which appears to me to be an unanswered reply to a post of yours. What do you want to be convinced of, that your debunking of philosophy and philosophers is lacking, or my views? The two are not necessarily the same. I think you'll find it's a bit more complicated than that ... |

What do you want to be convinced of, that your debunking of philosophy and philosophers is lacking, or my views? The two are not necessarily the same. What criteria do you propose to measure whether something is convincing? Are you certain of the answer regarding the hypothetical falling tree? I note that you have again chosen not to respond to the content of that earlier post. I think you'll find it's a bit more complicated than that ... |

What do you want to be convinced of, that your debunking of philosophy and philosophers is lacking, or my views? The two are not necessarily the same. But isn't that where this subject should be, in Politics. And if you really don't think so, then I suggest you look up that 1st our PM has in a subject that many regard as being the politics equivalent of media studies. |

They will also therefore produce similar real sounds whether or not there is anyone in the vicinity to hear them and witness it. I'm not sure they do though... not in the sense of an actual sound. They do produce pressure waves (at least I think that's what they're called) and those need to be translated by an ear or some other "hearing" device to be recognised as sound. I think. Take for example a dog whistle. We would say there is no sound coming out of it, and if we didn't know such things exist, we would throw it away as a useless/broken whistle, probably around the same time as we got bowled over by all the dogs in the neighbourhood. Where was the sound? In their ears! Getting back to the tree, we could say it "made a sound" when it fell, in the hope that the squirrel in its path wasn't deaf, and so would hear it and have a chance at escaping, or... on the off chance that one of us was wandering around in the forest and might hear its last "words" about clinging to the planet no more no I will not put that weird jacket on... no I won't! :) I know I have more - but will I have to post it in Bobby's thread, Chris? :) Sorry... didn't mean to keep you waiting so long for a reply the real question is why does it matter to you, and why do you want to know this? If it is because you feel sorry for a big fish trapped in a small bowl when it should be in a proper tank, that is different. None of my fish are in a bowl, nor is their tank too small. I wonder because they watch us when we're pottering about, and not just when it comes to being fed. That they find what we're doing interesting enough to take note of, makes me wonder what they think I'm pottering about in. Ok, so these entirely new and refreshing ways have achieved precisely what? Cured cancer, poverty, stopped wars, taken us to the stars? Did you, when you asked me your question? :) I wish I had when I asked you mine, but that's not how things work. Does art do any of those things? Should we do to all artists what you think should be done to all philosophers? :) ask the 90% of the worlds 7 Billion population why they continue to pursue and worship their Gods. Logical deduction, faith, lemming-itis, or are they all philosophers? Yes, well, it did occur to me whether the falling tree question was more of a cynical aside about a certain god seeing even a sparrow fall... and then just watching and watching till it went splat, but I won't go into that here. As regards the question about how many facts are still facts now... the best science teacher I ever had at school made it very clear that everything he would teach us that year, could be proved to be wrong, or very different within our lifetimes, and that what we thought we'd learned from him, he hoped would keep us interested in the subject long enough for us to know if and where he'd been wrong :) He was a fantastic teacher, and I've tried to make use of that lesson in every sphere of life. And perhaps we should also remember that when the falling tree question was posed, it wasn't this century. Nor the previous one. We know so much more now than then, but then... well that must've been an amazing question to even think of trying to answer oh...and did we say we like humans too? Well we do :) |

And what if a third party, some way off, heard a tree falling down, but couldn't find it so assumes she is imaging things or going mad. (no not you Annie) |

Sigh. Sigh indeed. For a moment I thought this might be an interesting challenge. Instead you appear to want to play a game where only you are permitted to see the rules, and cry foul when another requests a copy. What might have been an interesting challenge is, instead, likely an impossible one. If, as you say, by definition "a falling tree makes a sound", then you are right, the epistemological question is pointless. If you want to understand why the epistemological question might not be pointless, a first step might be to consider why such a definition may not be universally accepted, a second step might be to consider what you mean by "sound". You may say "life is a constant learning process", though it seems you are unwilling to expose yourself to learning in this area. I applaud you, sir, on your well deserved, albeit phyrric, victory. I think you'll find it's a bit more complicated than that ... |

You may say "life is a constant learning process", though it seems you are unwilling to expose yourself to learning in this area. My terms (which, amounted to a request for you to share your terms) have nothing to do with my assessment about your unwillingness to learn, you ruled out the possibility of learning by saying something was so by definition, you also made the challenge of convincing you of alternatives an impossible one by making disproof a requirement. You may be right in that it is "just two people who disagree", though I suspect what we disagree about is more fundamental than philosophers, philosophy, trees and sound. If you were to claim that I am surrounded by intangible, invisible, pink unicorns, it would likely be beyond my means to disprove you even if we were in complete agreement on all the terms in the phrase "surrounded by intangible, invisible, pink unicorns". To my mind, expecting anybody to provide disproof when it is unclear that terms are mutually understood is, to say the least, unreasonable. It is in part, for this reason that skeptics, critical thinkers, users of the scientific method and, yes, courts place the supporting evidence burden on the person making an assertion, and not on others to disprove the assertion. Back to the topic of the OP. If, as you now say "[i]n physiology and psychology, sound is the reception of such waves and their perception by the brain" (emphasis added), how can there sound if there are no brains to perceive it (which is essentially the scientists response to the tree question noted earlier in the thread)? Or do physiologists and psychologists use an incorrect definition of sound? I think you'll find it's a bit more complicated than that ... |

No, by logical deduction means by logical deduction, by definition means something else entirely. Yes, circles is what we will travel in while you abuse terms as they are commonly understood. BTW, who developed the tools of "logical deduction"? If you were to claim that I am surrounded by intangible, invisible, pink unicorns, it would likely be beyond my means to disprove you The alibi is an assertion (the defense asserts the defendant was elsewhere at the time). The example does not support the "Not always" assertion. Back to the topic of the OP. If, as you now say "[i]n physiology and psychology, sound is the reception of such waves and their perception by the brain" (emphasis added), how can there sound if there are no brains to perceive it (which is essentially the scientists response to the tree question noted earlier in the thread)? Please re-read the article linked in the OP ("If a tree falls in a forest and no one is around to hear it, does it make a sound?"), in this case we are explicitly talking about a situation where there are no human beings hearing the falling tree. If sound requires brains, does the absence of brains result in the absence of sound? Clue, use logical deduction ... Or do physiologists and psychologists use an incorrect definition of sound?I wouldn't know, go and ask some! We can all hear noises, but we perceive them differently. I might think that some pop music is utter trash, others might love it. You cannot see the posts about logic made by me and others that you have not addressed? Are you suffering from confirmation bias? I think you'll find it's a bit more complicated than that ... |

I have made a statement that I cannot see any point in philosophy or philosophers, Then it is just as well that others do, Mr S, or we might still be transporting slaves to our colonial plantations and crippling the rights of women to the level we used to. Philosophy deconstructs an accepted view of how something is (or is perceived to be) set in stone. That, frees the mind to analyse from a viewpoint that may be very alien or counterintuitive to us at first. Then we reconstruct, and that can mean putting everything back the way it was. The abolition of slavery however, would not have happened without an initial philosophy behind it. Nor would gender parity. If you have ever benefited from a doctor's treatment, then you have benefited from a philosophy that questioned whether disease and affliction were punishments for a sin. Philosophy is not a static state. The best melts into the background of the progress it led to, as some here have already tried to point out to you in the fields of maths and science. That does not detract from its worth. Stop looking for a seed to ridicule when the tree it has grown into is towering above your head. An interesting thread though. Thank you. :-) edit@anniet: that must've been an amazing question to even think of trying to answer And to construct :-) We have nothing to fear but fear itself. Apart from pain. And maybe humiliation. And obviously death. And failure. But apart from fear, pain and humiliation, failure and the unknown and death - we have nothing to fear. Who’s with me? |

Here is a graph of field of science. As others have stated and I posted here some years ago, mathematics and science most definitely arose from philosophy. Thank Euclid for putting it on solid ground to silence the sophists. Luckily, Chris is on solid ground ... solid for 3500-500 BCE. |

No, by logical deduction means by logical deduction, by definition means something else entirely definition the act of defining, or of making something definite, distinct, or clear: deduction Logic. Indeed it was rubbish for me to simply say that these things are different without providing evidence demonstrating that difference. My apologies. From the link provided:The alibi is an assertion Statutes or court rules commonly require that to assert alibi as a defense, a defendant must notify the prosecution in advance of trial and furnish the names of witnesses the defendant intends to use to support the alibi In other words, an alibi is an assertion and courts require the defendant to support the assertion. How is this any different to what I said in earlier posts, that "courts place the supporting evidence burden on the person making an assertion, and not on others to disprove the assertion", and "[t]he alibi is an assertion (the defense asserts the defendant was elsewhere at the time)"? Or are you conceding that your example for "not always" did support your claim? Are you suffering from confirmation bias? You are doing more than that, "so far I have not seen any response that makes me think any differently", to have not seen the posts on logic may be indicative of confirmation bias, to have seen the posts on logic and still reach the conclusion that "I cannot see any point in philosophy" is a declaration of willful ignorance. I was trying to be charitable, though please do feel free to remove any doubt. and my viewpoints and opinions are as valid as anyone elses. Sorry if you don't like that. Not so, you are as free as anyone else to voice your viewpoints and opinions on these boards, and I have no argument with that. That there has yet to be an independent assessment of the validity ("the quality of being logically or factually sound; soundness or cogency") of any viewpoints and opinions voiced here, does not make them all equally valid. For all I know, your views and opinions are more valid than everyone else's. Apologies for the recent RFI my filter is on the blink, I'll deal with that later. I think you'll find it's a bit more complicated than that ... |

Valid Question. Q2. Why?Valid Question Q3. Who gives a damn anyway?Killed the thread. It's been an interesting thread with some interesting posts. Unfortunately, Q3 has killed the thread. For those who feel philosophical & ask as to why, think carefully before it's asked. |

At the risk of seeing this thread moved somewhere else, I will reply one last time. Ask everyone then. In the context of a thread on Philosophy, the meanings of by definition and by logical deduction are distinct, the former is a premise, the latter is a conclusion leading from a set of premises, that you believe that there was some other context for your post is fine, I was not aware of that alternative context. And statement begins with an s in UK and US English. It would have been more constructive to have discussed the tree which is one of the subjects of this thread. Tried that, you chose not to respond to those posts. Or are you conceding that your example for "not always" did support your claim? In US criminal courts there is still the presumption of innocence. so the accused does not have to do anything, I'm not sure whether the presumption exists in the UK anymore. Even without the presumption which "side" was indicated in the sentence "courts place the supporting evidence burden on the person making an assertion, and not on others to disprove the assertion"? You might chose argue that the counter assertion of alibi disproves the initial assertion, I've yet to see you try, though before you do, you might wish to review what "disproof" means in the context of Philosophy. is a declaration of willful ignorance In UK English perhaps (though I count two in your spelling of the word), in US English there are three ls in willful. The point that you seem to miss Bobby is that I have no interest in trying to change your mind about anything that you may think. Whatever it is you are welcome to it, and I can simply choose to agree or disagree. Some people use the tactic of "I'm having trouble understanding why I can't convince you that you are wrong and I am right". And worry it like a terrier with a bone. Nope we don't play those games. Logic does not convince you of the usefulness of philosophy? I suppose I should not be surprised. To the best of my knowledge, I have not said a thing about grammar; while we have side-stepped into the related field of semantics, the side-step did not require this thread. Lets for the umpteenth time go back to square one. If this damn tree falls in the forest and nobody is there to see it, does it make a sound? A1. Don't know. A2. No direct evidence. A3. Quite (though not completely) sure I do; I don't know whether anybody else does. Before you reply, please take a moment to think about what I might mean by "know", in the context of this thread, the word might not have the meaning you currently think it does. I think you'll find it's a bit more complicated than that ... |

Hearing trees falling in a forest? I have even problem to see the forest because of the trees. |
