Taming The Infinite/ Chapter 11/ Firm Foundations.
In the lack of computations made by computers, human beings needed to make them themselves. Therefore, inevitably, equations rose to their highest quality intending to define these difficult "functions". We have seen a variety of historical accounts, some more explicit than others, but none could have sustained itself if it weren't because of the contribution that previous predecessors provided. “Calculus became undeniable”, the book remarks, in its due course that is true, but why hold on to the notion that it will forever be undeniable. There are many mysteries in mathematics, or life in general, that we cannot yet explain. Godel tells us this, but that is of another further matter. Do we understand infinity for instance, just as Cantor; things are not as "simple" as they appear to be quite often, mathematics is one of them. However, we can agree that we now possess certain "pillars" that lead one closer towards truth, or the idea of it at least. These are the firm foundations, and Calculus provided most of them.
