11/9/2015 8:51:19 PM Posted: 1 year ago Alder's Razor: "Any matter that cannot be settled through observation is not worth debating."
It's also known as "Newton's Flaming Laser Sword"; just as Occam's Razor cuts out redundancy, NFLS cuts out abstract, wishywashy arguments with no basis in fact. https://en.wikipedia.org... https://philosophynow.org...

11/9/2015 9:19:32 PM Posted: 1 year ago How exactly is one supposed to "observe" that only observation is capable of arriving at truth? Obviously some truth falls within the scope of science, but does all of it? How is science going to tell you, when the limitation of its scope is precisely the question at issue. So you're actually putting forth an axiom, which if we accept as valid, refutes your argument, since clearly a true axiom would show that not all truth has to be "observed", as your argument assumes.

Alder's response is that mathematics is merely an extension of realworld stuff. For example, Euclidean geometry (geometry on a flat surface) is abstracted from the Egyptian method of using pegs and ropes to mark out fields. Since field markers deal with flat surfaces, Euclidean geometry cannot be used in situations where the surface is not flat. Or, to put it another way, Euclidean geometry tests whether the surface you're working on is flat. If you construct a pegandrope triangle, and the angles add to more than 180 degrees, then your surface is probably spherical (a version involving mountains and telescopes was used to determine the curvature of the Earth). This is why we use fancy mathematics such as imaginary numbers: they are abstracted from realworld phenomena that obeys those rules.

If you crunch the numbers, and they don't match observation, then your maths is wrong.

Where practical and useful theories can't be settled by observation alone? "At the heart of the underdetermination of scientific theory by evidence is the simple idea that the evidence available to us at a given time may be insufficient to determine what beliefs we should hold in response to it. In a textbook example, if all I know is that you spent $10 on apples and oranges and that apples cost $1 while oranges cost $2, then I know that you did not buy six oranges, but I do not know whether you bought one orange and eight apples, two oranges and six apples, and so on. A simple scientific example can be found in the rationale behind the sensible methodological adage that "correlation does not imply causation". If watching lots of cartoons causes children to be more violent in their playground behavior, then we should (barring complications) expect to find a correlation between levels of cartoon viewing and violent playground behavior. But that is also what we would expect to find if children who are prone to violence tend to enjoy and seek out cartoons more than other children, or if propensities to violence and increased cartoon viewing are both caused by some third factor (like general parental neglect or excessive consumption of Twinkies). So a high correlation between cartoon viewing and violent playground behavior is evidence that (by itself) simply underdetermines what we should believe about the causal relationship between the two." http://plato.stanford.edu...

I can then expose half of the children in each group to cartoons, monitor their behaviour over the next 4  6 weeks, and compare them to the control groups. The problem with both your examples is a lack of observation, not a failure of observation as a method. If you don't make observations, you cannot draw conclusions. If you're not willing to make or accept observations, then that's as bad as being unable to, and thus the debate is not worth having. Alder's Razor is not just a tool for eliminating pointless debate topics; it also eliminates pointless debate opponents.

You are not deriving 1+1 =2 by counting one apple, another apple, and then concluding that they equal two. Rather, you are assuming that 1+1 =2 in the first place. Counting two apples does not prove that 1+1=2. Rather, 1+1 =2 allows you to prove that you have two apples. 1+1 will continue to equal two whether or not there are apples, or whether or not there are any physical entities at all.

They are merely a way of representing a relationship between two or more variables. The rules of logic arise from observing patterns. If your logic is false, then you will not be able to continue the pattern. If you're struggling with this concept, then imagine the following scenario: You've been transported to another universe, where the rules of logic are different. How would you discover what these rules are? Furthermore, mathematics is not always a description of real world entities like apples. The average household cannot have 3.5 people in it. 3.5 people is an average; it refers to a trend in the larger population, and not in a specific house. The math is descriptive, it just isn't describing what you claim. Take "1 + 1 = 2". This can be inferred by counting one apple, counting another apple, and then putting them together and counting both apples. Hence, the equation is an extension of a realworld observation regarding how apples add together. Continue the "other universe" scenario. Suppose you counted one apple, counted another apple, and then put them together and counted three apples (assume that you counted correctly). Would that not invalidate the 1 + 1 = 2 rule? Suppose that, no matter how many apples you added, having more than one apple produced three apples? 1 + 1 = 3, but so does 1 + 1 + 1, and 1 + 1 + 1 + 1. Basically, any numbers other than 1 and 0 add to 3. Would that not invalidate the entirety of arithmetic and, by extension, all of mathematics? If you want proof that this is how stuff works, look at all the new types of numbers we have to work with nowadays (e.g. the ones where A x B = B x A). We didn't pull those numbers out of thin air; they were created out of necessity to describe a concept that our existing mathematics couldn't.

11/10/2015 8:51:28 AM Posted: 1 year ago You can have it both ways. You could say that 1+1=2 is a generalisation of our observations of gathering objects together or that 1+1=2 is a inviolable rule of abstract mathematics that can be applied usefully in the real world when gathering objects together.
I don't think either model is more correct than the other. Rather it is good to have a 'split personality' and hold both models in your head so you can use the model that works best for whichever problem you are working on at the time. There's no overriding necessity to dogmatically adopt one and abandon the other, rather like you don't have to decide if electrons are waves or particles.

Or, more likely, Natural Selection wired addition into some primitive mammal's brain so they could tell how many more nuts to gather. Regardless, the rule only exists because we can observe it and it works.

Cavemen didn't have imaginary numbers! Imaginary numbers arose our of efforts to solve algebraic equations  a problem of pure mathematics. Imaginary (or complex) numbers are certainly used in physics (e.g. for working out the parameters of resonant LCR networks  but complex numbers predate electronic circuit design. Noneuclidean geomety is another example where mathematics came first and was applied later when it was realised the universe was not flat after all. I am not arguing that mathematics does not have its roots in observation and practical problems  my position is that its not an either/or thing.

11/10/2015 9:09:01 PM Posted: 1 year ago Hey  I'm trying to be neutral here, sm2!
I think that maths certainly started out as little more than a way of organising our experience of dealing with small collections and quanties, expanding only a little when we began to trade (non trading hunter gatherer societies often had no words for quantities larger than two or three). It is relatively recently  and gradually  that maths has became divorced from the mundane and became truly abstract. I confess that if I hear mathematicians discussing their trade with each other it is like a different world. nploid toroidally tesselated zmanifolds aren't something I have ever experenced... . A classic paper on this topic is this one. Everyone should read this before posting on mathematics! http://citeseerx.ist.psu.edu...

11/10/2015 9:11:36 PM Posted: 1 year ago I'll just quote from the wigner paper I linked:
Furthermore, whereas it is unquestionably true that the concepts of elementary mathematics and particularly elementary geometry were formulated to describe entities which are directly suggested by the actual world, the same does not seem to be true of the more advanced concepts, in particular the concepts which play such an important role in physics.
