I don't agree with this, or rather I think it would be impossible for us to make any sort of assumptions about what an extraterrestrial race might assume about reality. The axioms are built fundamentally on the particular way in which we perceive reality and how we group sensory data. We take our view of reality for granted since its the only one we know, but its entirely possible that an alien species could evolve to perceive reality in a way that we are unable to imagine. As long as the intelligence is able to successfully interact with its surroundings, the perceptions need not conform to what we consider real or normal. |

Another thing to consider is that along with humans, other animals also use math. |

I think the key is that humans are the only ones to have conscious mathematics. This gives us the ability to discover and prove new theorems, and analyse mathematical thought as a whole. |

I am cool beans with general relativity. It does not disprove the existences of planes and other figures. Geometric figures are zones and do not have to conform to the curvature rules of space or matter. However, there is a separate set of laws for the principles of projections of such figures curving with space. |

How do you know you are not dreaming right now?

Real numbers can represent real things, such as distances. A number line can coincide completely with distances and degrees of difference, etc. Complex numbers, on the other hand, include imaginary numbers, which are called "imaginary" as opposed to "real" for a very literal reason. They can represent unrealistic hypotheticals, but not actual realities. |

My reflex-reponse upon hearing claims of "absolute truth" : man is NOT the center of the universe. Forced to accept that in the physical sense we cling all the more dearly to the hope that at least the thought-world still revolves around us. |

"you only lose what you cling to"
Responding to the original topic here: |

Maths are like colour. They've been there, we just gave them names. |

The problem is that there is no intrinsic object in nature. We decide what is a discreet thing and what is not. Therefore, in order to count a group of things you must first define what is one thing and what is another thing. Someone else may very well decide that what you count as two... diamonds for instance, are really not two diamonds but xbillion carbon atoms, or what have you. The designation of things to count is in itself a construct created by humans. |

I basically agree with that. |

Unless one is directly perceiving the true nature of reality, one is perceiving a man-made concept. Concepts, ideas, notions and the like are useful because they help us to classify and to discuss our perceptions. |

You professor friend probably conceded the bet because somebody who is a professor in mathematics should have known better than to enter the bet without agreeing to a definition of 2, 4 and +. |

What I actually bet her was that I could prove that "one plus one equals one" (spoken, not written). She probably fell for it because I used such basic units, and there was no money involved. She tells me she has used it to great effect with her colleagues. I've told her to call it "The Oneiro Conundrum". Heh. |

This makes more sense. For example any mathematician would know that 2 + 2 = 1 mod 3 but there's no n so that 1 + 1 = 1 mod n. 1 + 1 = 0 mod 2 and 2 for all greater n. The integers mod n is pretty much the canonical example redefining +. |

Well that's as clear as mud, but thanks for giving it a bash anyway. |

Like some have said here Philosopher, the only reason why you take these things to be truths is because of the very specific way in which you are capable of perceiving reality. Xei brought up the example of non intersecting parallel lines. We believe this to be a self evident truth because we are beings that are limited to non-relativistic temporal-spatial conditions. A being that spends its life traveling near the speed of light would have a very different idea of what is self evident about nature than you do. |

This just isn't a good example. It depends on what the lines are embedded in. If they're embedded in flat euclidean space, then it is a fact that they'll never intersect. This is old news. If we model the space with the reals, then we can prove it. It's also old news that two straight lines in a sphere that are perpendicular to a great circle and parallel at their intersection with it will intersect at both of the poles determined by that great circle. Think of two of the lines (lat or long? I always forget) that are perpendicular to the equator on earth. They intersect at the north and south poles. So it all depends on our definitions. |

I guess we agree on the essentials. As long as we recognize that we are starting with inherently human definitions then we will continue to agree on the outcomes of those definitions. The only logical leap that I am unable to agree on is your belief that these outcomes would necessarily hold for any extraterrestrial that may or may not be operating on completely different assumptions that we are unable to imagine. |
