Thank you, Mark, for this excerpt. I believe math is an abstract aspect that accompanies reality. One + one = two means nothing if we do not declare what the entity is. One chicken + one chicken = two chickens does make sense.
Just for you, I hope you want to read about my mathematical evidence (actually, it is evidence about the mathematical building blocks, so technically not mathematical evidence in the classical way) that zero is a natural number after all. Set theorists are therefore correct, number theorists are not. As deeper conclusion, one must reject the idea of singularities, because a natural zero indicates that there are then always two self-based aspects at minimum.
Math encompasses not only reality, but all aspects of reality, including the artificial reality (think computers or think money). Math is therefore subject to manipulation (case in point, through establishing a definition that declares zero to not be a natural number) and we need to overcome the manipulation to see math for what it truly is. Without this information, math cannot be viewed correctly.
