Planet youhaventseenit in the Horse Nebula is material. Can you destroy it? No! Could it be destroyed by an unfortunate event? Perhaps. But if the number 1 is just an abstract thought, then that thought can seize to exist. > Even if the entire universe were destroyed, mathematics would still exist. You presuppose that maths is immaterial to proof that it's immaterial. That stance cannot be argued with, because you cannot show it to be true. If thought seized to exist, there would be nothing left to argue with, so this is reductio ad absurdum either way leading to a false dychotomy. What remains is: "maths" does exist. So my stance holds as much explanatory power as yours, no more, no less, but yours is metaphysical. You idealize things you don't understand, unless you have a concrete plan of action to "Recreate the universe again".
