Axioms are just that, their axioms derived from suppositions. In addition to Simberto's points, How it should work is that: axioms are true by definition, postulates are tentative truths so you can actually apply logic. Axioms can't be proven to be true or false, they simply are true. Postulates can be proven to be false, and postulates are the basis of arguments (premises). In reality they're basically the same thing because English. Axioms are true in whatever universe you describe them in and one day they might be false. But then they shouldn't have been classified as axioms in the first place. Multiple definitions whooo | ||

If you are only staying for a short period of time, phone internet/surfsticks. If you are staying for a longer period of time (months at least, talk to phone companies, but if there are no cables laid, its probably cheaper to once again use phone internet. If you really hate phone internet, ask before you rent the house if it has a connection. If you are so far out in the wilderness that you don't have mobile connections, you probably have a reason for going there like wanting to do some sort of rustic wilderness trip, so you should be able to deal with not having internet for a few days/weeks. | ||

What's so special about S. Why not "A" or something? Anyone know? | ||

I think it's similar to how games will have bronze/silver/gold for standard placements and then a platinum medal for bonus placements like for beating a record time or a challenge that otherwise doesn't follow the typical scaling. It's an additional ranking intentionally above the standard that says that the recipient is special in some way. | ||

All break down to the simply just arbitrary beliefs that one must assume is true for the following discussion to take place--hence why I asked how does one know something is true without direct evidence being that they all beging with "assuming x is true, then so are all these other things." I know I exist because I perceive myself to exist. And I have faith Africa exists, because books and people tell me it exists. But until I see Africa for myself, or see direct evidence of Africa myself, I simply have to trust the books and people around me. | ||

No. It makes you look like an illiterate. (And is technically against TL rules). | ||

Or rather who defines something to be axiomatic? If I write a proof using an axiom that states 2+2=8 then you will obviously point to that and say it's wrong and therefore my conclusion is wrong. My take on the definition of an axiom is 'something so simple I'm not going to bother providing proof.' But that does not inherantly make it true or mean there is not evidence out there to reinforce the idea. | ||

Of course, you also have most of modern mathematics built on even more abstract axioms, like Zermelo-Fraenkel set theory, but those are really abstract and kind of hard to wrap your head around for most people. Now, if you were to change one of them, for example use a+b=b+2a instead, you would get a completely different working set of algebraic equations following from that. This is not a wrong system of algebra either, just a different one built on different axioms. And in that system, a+b=b+2a is an absolute truth, needing no proof either. Inside it's own system, an axiom is true without requiring evidence. Trying to determine if it is true outside its own system is kind of pointless and does not really lead to anything. This is the beauty of maths. Maths does not have to fit any observations or evidence, math just is. You choose axioms, and derive from there. The axioms are true without requiring proof, and everything else follows from the axioms, and can thus logically be proven to be true. You create a consistant system that is completely true, and will always be completely true (unless you made a mistake). | ||

http://en.wikipedia.org/wiki/Hilbert's_second_problem Regarding the question of knowing what is definitive or not without evidence, there are gigabytes of wikipedia pages you can read up to familiarize yourself with the subject and gauge how interested you really are before delving in the sinkhole of primary texts: http://en.wikipedia.org/wiki/Epistemology | ||

The wiki article is interesting too That purported definition is a bit of polemic pandering by espousing a ostensibly proper way to use the word "axiom." Euclidean geometry is very much a thing, and the axioms for it are just as valid now as they were back then. In fact, the various axiomatizations of Euclidean geometry behave much nicer than the axiomatizations of arithmetic, despite one being relegated to the status of postulate by our fellow magisters of The Important of Philosophy.

My main argument was that arithmetic is a poor example of demonstrating the inherent truth or provability in an axiom within its own axiomatic system to be used as an example of how you can define something, presumably as true, without experiencing it. The point of an axiom isn't to be self-proving (vis-a-vis a tautology) but to create the basis of an interesting structure that logical deductions can be made from. | ||

Axioms also become very tenuous affairs leading to lots of arguments when you stray away from mathematics. For example, when designing laws, are people generally trustworthy or generally untrustworthy? When discussing ethics, whose morals should we use as a base point? Etc... | ||

I might just be another Burkean shill, but I think the way he put it was best: The individual is foolish; the multitude, for the moment, is foolish, when they act without deliberation; but the species is wise, and, when time is given to it, as a species it always acts right. In my flow of thinking, the longevity of laws and the societal results from abiding by them should be viewed together, when untrustworthy might think of submitting to laws long established, and trustworthy flourishing with all their protections and benefits.Axioms also become very tenuous affairs leading to lots of arguments when you stray away from mathematics.
