And doesn't work in areas like infinity. For example, if we can conceive of
infinity + 1, then does that prove that infinity isn't infinite? Challenging
someone to find a workable value for the delta is simply inviting them into
a mathematical trap, like challenging them to find a workable value for
infinity itself as a way of proving that infinity can't exist.
