You're simply mixing belief and knowledge.
You're mistaking the action or location of an object for the proof of the existence of the object, and they're not the same thing.
Volcanoes exist, lucky charms exist - they just don't exist in your hotel room or kitchen presently, they nevertheless exist.
Forget all your arguments about volcanoes spewing in hotel rooms or kitchens - just try something simple like proving the non-existence of something.
Simply try to describe the process for proving that talking, blue diamonds do not exist. - without saying there's no evidence of them.
Permalink Reply by Park Bierbower on March 19, 2011 at 7:38am Thats not the point. The case for god is SPECIFIC, its not just "there's some god out there," it has motivations, desires, and consequences attached. If there was a god, there would be evidence of it~ something as distinct and defined as the god in the bible would not exist without effecting the environment that it operates in. So far there is NO evidence of such a thing. The pink unicorn argument is a non sequitur~ it does not come with the caveats that god does~ location, for one, along with behavior, motivation, and intent. If you added those parameters to the pink unicorn argument, you could prove, through their absence, that they do not exist. for example~
Pink unicorns exist. They live in parking lots, get angry when you touch their shopping carts, and eat cigarette butts. Examine
for this scenario, in examination, you would find a parking lot. You could walk through it, hoping to bump into a unicorn. You could also have many people handle shopping carts, to incite some sort reaction from said unicorns~ you could also measure the amount of cigarette butts on on the ground over a number of days or weeks, to determine if any disappeared unaccounted for; possibly eaten by the unicorns.
After all of those variables did not change, you would be able to determine that the pink unicorns in question do not exist. Their existence is contingent on several things~ specifically the details in their definition. When those consequences fail to emerge, you can say that those details are incorrect~ you must then change the definition of the pink unicorn if you still wish it to exist~ but then you have already disproven the original premise.

Ivory Soap Non-Theist here. (Yes, I find it hilarious so I'm taking on the label) I've been reading more about this 'not being able to prove a negative' thing - more specifically the link that you posted here. I'm baffled. If you can find the time, I would like to hear your opinion on the following:
Mr. Hales stated: For one thing, a real, actual law of logic is a negative, namely the law of non-contradiction. This law states that that a proposition cannot be both true and not true. Nothing is both true and false.
I can think of at least 3 different examples of how a proposition can both be true and not true at the same time. All of them are primarily based on perception - which is a major facet of obtaining scientific data.
1) Taiwan I'd say 'enough said' but by stating the proposition: Taiwan is a member of the Peoples' Republic of China (PRC). This is both true and false depending on different individual's perspective.
2) Objects at rest. (Newton's first law) The cup on my desk is at rest; however, it is also in motion because the earth is in motion. [I'll expound on this but only if you're interested.]
3) In responding to the proposition 2+2=4, I would hope a reasonable response would be: From what observable data do the numbers 2 and 2 come; and for what is the number 4 being used? This proposition/equation/tool-of-math is far too over-generalized to be of any use (much like the word God) without exposing the source of measurement and its application. Did some observer originally measure 2.0000000001 and another 2.0000000002, determine the units are used only in feet, then round off? The answer 4 is true. The rounding is accurate if we're moving the aforementioned cup 2 ft then another 2 ft guranteeing a 4 ft result. But if the rounded 2's are used in a complex project to account for a 4 ft shift if we're sending the cup 20 light years away, that would be a different perspective where the 4.0000000003 ft would be important.
Most importantly, (if I'm so far off the mark that you simply don't have the time to even begin educating me on the errors of my way) I must know: What on earth do you have against Ivory Soap? I've used the products for years and they're awesome!
Thanks in advance.
Permalink Reply by Marc Green on March 23, 2011 at 2:06am Thanks. A little humor to lighten a topic is always a good thing. I hope the 100%er's aren't having secret meetings to excommunicate us Ivory Soapers from the Non-Theist Church. It would be such a shame to have to call up my Atheist Mafia friends. (Admit it... you really enjoy this topic :)
But my examples are not only objective and contradictory, they are self-evident. Math fails in the sense that one should not have it both ways: there is an infinite amount of decimals between any two numbers (a tangent to a line) AND it is also possible to reach the next number (completing the tangent). Either you can't get to the next number or there are a finite amount of decimals between two numbers. I say we 'should' not have it this way, but we do. We accept it as contradictory but we don't discard the usefulness of the tools.
You did propose 2. But much like the term 'God', without inquiring further into how it was gathered and for what it is used, it's just a useless digit typed on the screen. [I'm imagining the carpenter who refuses to build the building because his 2x4's are all mismatched to the 10th decimal place. That would be a hilarious conversation with his contractor.]
I'm really only debating this False Dilemma because I can't seem to fathom why some people need to have absolute certainty of things. I don't understand it coming from the religious and I don't understand it of the non-theists. You do seem to be the most adamant on here to the latter.
Oh, BTW. The cup on my desk has not moved. (I began measuring and re-measuring since my last post) But I suppose the Earth hasn't moved in the meantime.
Thanks for being a great conversationalist and a good sport.
Permalink Reply by Marc Green on March 23, 2011 at 9:34am What I'm looking for now is how to prove a positive with absolute certainty.
The other day I brought home 2 "things". Yesterday I brought home 2 "things". Does this mean I now have 4 "things"? I can say yes. But that might be a presumption if I don't investigate further what those 4 "things" are.
I had brought home 2 white swans and then 2 black swans. Does this mean that I have 4 white swans? No. {OMG, did this guy actually kidnap swans to make a lousy point on a website? Does the ASPCA know about this thread?} Do I have 4 birds? Yes. (And I'm not giving them back. They will be well cared for.)
A proposition can both be true and false if it's so over-generalized like the proposition 2+2=4
The assertion one can prove a negative from the premise that a proposition cannot both be true and false is either: 1) a fallacy because there do exist propositions that are both true and false; or 2) a tautology if one defines the word "proposition" as a statement that cannot both be true and false. Either way it's improper.
So I'm now seeking even one positive proposition which by itself cannot both be true and false even upon further investigation.
BTW, I did see your response to Joel concerning the inability to absolutely prove (not claim) the existence of "God". Very nicely stated indeed - all of you. ;D
Permalink Reply by Marc Green on March 23, 2011 at 10:12am Oh, yes. I find it fascinating the micro and macro universe. It's a mental technique I do to try and imagine making myself smaller and smaller, etc and what the perspective would look like. (LOL if you could watch me through a microscope trying to breathe in that one gigantic oxygen molecule to stay alive - hilarious) I do the same in the macro way - larger and larger, etc. Fun things the minds do invent. I do hope scientists will be able to view these perspectives better in the future.
Thanks for your posts, Vince's and all the others I cannot name at the moment. It really is a fascinating topic and there are lots of great people on this site.
Permalink Reply by Marc Green on March 24, 2011 at 3:10am I could take the time here to posit responses to each of your points. And as much as I would LOVE to, I don't want to appear to hijack this thread any more than has already been done. I've given my opinion as to the question posed. I've also given many examples of things that have a property while simultaneously not having the property. So, we regress.
As I've stated, I'm currently looking to get some insight on why people feel a need to pursue absolute certainties; and once they believe they have found them, do often act in extreme ways (such as speaking angrily resolute, authoritarian and condescending toward others.) But now I'm also gleefully looking to find even one positive incontrovertable proposition. So, as soon as I can figure out what to do with these swans (can't keep them away from my cup), I will begin a new thread in either the Science or Philosophy Forum.
