Are Numbers Real? Is Maths Real? Or Is It Just A Construct By Humans? Philosophical Questions and Youtube Videos!


Are Numbers Real?
Lately I have been pondering over numbers, which to the right kind of mind are a wealth of; interest, mystique, creativity & logic (I will cover a topic to that of 'the right kind of mind' at a later date under the name Maths gets a bad press) but a significant question arises when thinking about maths... Is it real? This question while rhetorical to you has been on the minds of philosophers for generations, from my deductive work I have come across three schools of thought on this.

1. Platonism - All numbers are some form of abstract objects that EXIST as a fundamental part of reality, our use of mathematics can be seen as a description of how these objects interact. Numbers, functions and any other form of mathematical expression are discovered NOT invented.
Unsurprisingly Platonism was first conjectured by Plato (of the famous GCSE a2+b2=c2 in right angle triangles formula) he tended to treat his maths as a cult with followers who would publically beat people for not knowing maths. This may seem absurd to think of at first, thinking there are an infinite amount of all the possible numbers being stored somewhere abstract  can at first seem a copout1 however as this is philosophy basically anything goes. It is generally not widely believed today on account of it being a bit out there. (pardon my obvious biases)

Of course some numbers are more abstract then others...
2. Nominalism - The real objects in the universe represent all numbers, maths is an integral part of our universe that is in place to make the universe work. Numbers, functions and any other form of mathematical expression are discovered NOT invented .
This may seem a likely alternative to Platonism we can confidently relate to real word objects more than abstract ones, 'is a bird in the hand worth two in the brush?' well according to the universe the IS a greater number of birds in the bush to your hand, likewise for any form of object; pencils, computers, white boards, sticky notes ect. of course I'm being somewhat facetious (pardon my obvious biases).What it really means is the universe is bound by maths at a fundamental level. So a satellite falling from a its curved geostationary orbit is forced to land the specific way it does due to the mathematics of the universe preventing it landing via any other; curved, strait or higgledy-piggledy path.

3. Fictionalism - Numbers are concepts invented by humans to describe the world around us the fabric of reality dose not rest on any type of numbers actually existing it just does what it does without any laws of mathematics behind it. Numbers, functions and any other form of mathematical expression are invented NOT discovered.
It may at first seem like how does this work at all if the world doesn't have some form of maths embedded into it? But just imagine maths as the tools we are using to pick apart how the universe is working. We use this tool to describe and explain just what exactly is going on it has no bias to exist in the actual universe and just gives us the numbers on what we think should happen.
Every ONE has days like this... *Crickets*

Now for the conclusion in my opinion fictionalism is the most accurate definition of what maths is I don't personally believe that we exist because of maths making everything work and I do believe that when Isaac Newton invented calculus2 he actually invented it, however I have just stated my views here to show my biases so you will consider them when reading3. throughout the descriptions I stated weather mathematicians discover/invent "new" maths this is an important point as an inventor creates and a explorer discovers stuff, this is leading to the discussion of weather they are discovering the mathematics laid down by the fabric of reality4 or if a new form of maths is created purely by the inventor of that form of maths.

Links to stuff REALLY WORTH WATCHING!

*Warning I found some links try to sway people to their beliefs mainly by comparing one of the other schools of thought to religion. I have tried to stay away from this in my description but if you hear this discussed somewhere they are usually using it as a tactic to discredit that school of thought by comparison to the illogical, which generally sways an otherwise overwhelmingly rational audience*

1The image of God with his infinite trophy case of all numbers, right next to his bookcase containing the elegant solutions to all possible functions comes into mind.
