I'm not proposing we ban Infinity altogether. I'm proposing that we restrict ourselves to only use Infinity in a potential sense. — Ryan O'Connor
"The philosopher and theologian are conscious of infinity, but from the mathematician's view they do no use it so much as admire it. The mathematician also admits infinity; the great David Hilbert said of it that in all ages this thought has stirred man's imagination most profoundly, and he described the work of G. Cantor as introducing man to the Paradise of the Infinite. But the mathematician also uses infinities..." Leo Zippin
"Every since we first sought number in the object, the series of numbers has begun with 1. Making zero the first of numbers means no longer abstracting them from the object" Jean Piaget
"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth
space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality." Hermann Minkowski, 1909
"At a time when Minkowski was giving the geometrical interpretation of special relativity by extending the Euclidean three-space to a quasi-Euclidean four-space that included time, Einstein was already aware that this is not valid, because it excludes the phenomenon of gravitation. He was still far from the study of curvilinear coordinates and Riemannian geometry, and the heavy mathematical apparatus entailed"

https://www.quora.com/How-can-I-a-non-mathematician-wrap-my-mind-around-the-Axiom-of-Choice: The reason the Axiom of Choice is (somewhat) controversial is that while it allows us to prove some very useful mathematical statements, it also allows us to prove some less
intuitive statements (e.g., the Banach-Tarski paradox).
And finally:
"As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality." Einstein

Thesis:
Every composite substance in the world is made up of simple parts, and nothing anywhere exists save the simple or what is composed of the simple.
Anti-thesis:
No composite thing in the world is made up of simple parts, and there nowhere exists in the world anything simple)
