The essence of mathematics lies precisely in its freedom.
The transfinite numbers are in a sense the new irrationalities [ ... they] stand or fall with the finite irrational numbers.
Interpretation
What this quote means
The transfinite numbers are an extension of numerical concepts that also depend on finite irrational numbers.
Georg Cantor's quote highlights the relationship between transfinite numbers, which extend beyond the finite, and the finite irrational numbers that form their foundation. It suggests that just as finite irrationals are essential to our understanding of numbers, so too are transfinite numbers important in the broader scope of mathematical concepts, illustrating the interconnectedness within the realm of mathematics.

All quotes βI realize that in this undertaking I place myself in a certain opposition to views widely held concerning the mathematical infinite and to opinions frequently defended on the nature of numbers.
Mathematics, in the development of its ideas, has only to take account of the immanent reality of its concepts and has absolutely no obligation to examine their transient reality.
A set is a Many that allows itself to be thought of as a One.
There is no doubt that we cannot do without variable quantities in the sense of the potential infinite. But from this very fact the necessity of the actual infinite can be demonstrated.

We must say that there are as many squares as there are numbers.
Why learn a number like pi to so many decimal places? The answer I gave then as I do now is that pi is for me an extremely beautiful and utterly unique thing. Like the Mona Lisa or a Mozart symphony, pi is its own reason for loving it.
A chess problem is genuine mathematics, but it is in some way "trivial" mathematics. However, ingenious and intricate, however original and surprising the moves, there is something essential lacking. Chess problems are unimportant. The best mathematics is serious as well as beautiful-"important" if you like, but the word is very ambiguous, and "serious" expresses what I mean much better.
Mediocrity would always win by force of numbers, but it would win only more mediocrity.
Like many a better one before me, I have gone down under the force of numbers, under the books and books and books that keep coming out and coming out and coming out, shoals of them, spates of them, flash floods of them, too blame many books, and no sign of an end.
