Here are a few quotations which show how mathematicians viewed their subject.

Arithmetic

God created the natural numbers. All the rest is the work of man - Leopold Kronecker; German mathematician and logician; 1823-1891.

God does arithmetic -Karl Friedrich Gauss

“Mathematics is the queen of sciences, and arithmetic is the queen of mathematics.” Karl Friedrich Gauss

Wherever there is number there is beauty - Proclus

“Why are numbers beautiful? It’s like asking why is Beethoven’s ninth symphony beautiful. If you don’t see why someone can’t tell you. I know numbers are beautiful. If they aren’t beautiful, nothing is.” - Paul Erdos

"As far as I’m concerned, prime numbers constitute a more stable reality than the material reality that surrounds us" A.Connes

Place Value System

“The ingenious method of expressing every possible number using a set of ten symbols (each symbol having a place value and an absolute value) emerged in India. The idea seems so simple nowadays that its significance and profound importance is no longer appreciated. Its simplicity lies in the way it facilitated calculation and placed arithmetic foremost amongst useful inventions. The importance of this invention is more readily appreciated when one considers that it was beyond the two greatest men of Antiquity, Archimedes and Apollonius.” - Pierre Simon Laplace

Geometry

Mathematics is the indispensable instrument of all physical research - Berthelot

A natural science is a science only in so far as it is mathematical - Kant.

“Music is the pleasure the human mind experiences from counting without being aware that it is counting” - Gottfried Leibniz

“May not music be described as the mathematics of the senses, mathematics as music of the reason? The musician feels mathematics, the mathematician thinks music: music the dream, mathematics the working life.” - James Joseph Sylvester

The man ignorant of mathematics will be increasingly limited in his grasp of the main forces of civilization. -John Kemeny The essence of mathematics is not to make simple things complicated, but to make complicated things simple. -S. Gudder

Math & Humanities

Doing Mathematics

"Math does not mean that you have to do it all 'in your head'. Mental math means that you do it 'with your head'"– Cathy Fosnot

"One enters the first room of the mansion and it’s dark. One stumbles around bumping into furniture, but gradually you learn where each piece of furniture is. Finally, after six months of so, you find the light switch, you turn it on, and suddenly it’s all illuminated. You can see exactly where you were. Then you move into the next room and spend another six months in the dark. So each of these breakthroughs, while sometimes they’re momentary, sometimes over a period of a day or two, they are the culmination of, and couldn’t exist without, the many months of stumbling around in the dark that precede them" - Andrew Wiles recalling his pursuit of a proof for Fermat's Last Theorem

So Mathematical Truth prefers simple words since the language of Truth is itself simple - Tycho Brahe, Danish Astronomer (translated from Latin)

Mathematics, rightly viewed, possesses not only truth, but supreme beauty—a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show - Bertrand Russel

“How does the mathematician — closer to the artist than to the explorer — by turning away from nature, arrive at its most appropriate descriptions?” – Mark Steiner

"The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning" - Eugene Wigner

“Mathematical concepts turn up in entirely unexpected connections. Moreover, they often permit an unexpectedly close and accurate description of the phenomenon in these connections.” - Eugene Wigner

‘Mathematics is simultaneously a discipline, a method, and a language, applicable to other disciplines or methods of knowledge, but also to mathematics itself. It is a mode of organizing, validating, and communicating knowledge, which uses the principles of logic and gives it a field of manifestation and application that is “pure,” free from contingency, and free from the confusion of natural language, in which the truths of propositions are universally valid and do not depend on any interpretation. It is the only discipline entitled to investigate concepts of any nature and any degree of generality, but also to be self-referential and self-applicable, as is in fact human reason.’ - Dr. Catalin Barboianu is the author of the book What is Mathematics: School Guide to Conceptual Understanding of Mathematics

“The mathematician’s patterns, like the painter’s or poet’s, must be beautiful … Beauty is the first test: there is no permanent place in the world for ugly mathematics.” - G H Hardy

"Only by giving up math’s connection to reality, could it guide us to a deeper truth about the way the universe works" -Derek Muller

"Mathematics is about relationships, relationships & relationships' - Christina Tondewold

 Imaginary Numbers

Square root of minus one in Schrödinger’s wave equation means that nature works with complex numbers and not with real numbers. Schrödinger put the square root of minus one into the equation, and suddenly it made sense. Suddenly, it became a wave equation instead of a heat conduction equation. And Schrödinger found, to his delight, that the equation has solutions corresponding to the quantized orbits in the Bohr model of the atom. It turns out that the Schrödinger equation describes correctly everything we know about the behaviour of atoms. It is the basis of all chemistry and most of physics. - Freeman Dyson, about the usage of imaginary numbers
