As knowledge of the alphabet and its permutations and combinations is to traditional literacy, and as a knowledge of numbers and their permutations and combinations is to mathematics, so a knowledge of the biological and conceptual alphabets of the brain and its apparently infinite permutations and combinations is to mental literacy.

What seems certain is that Pythagoras developed the idea of mathematical logic... He realized that numbers exist independently of the tangible world and therefore their study was untainted by inaccuracies of perception. This meant he could discover truths which were independent of opinion of prejudice and which were more absolute then any previous knowledge.
Simon Singh
It seems to me immensely unlikely that mind is a mere by-product of matter. For if my mental processes are determined wholly by the motions of atoms in my brain I have no reason to suppose that my beliefs are true. They may be sound chemically, but that does not make them sound logically. And hence I have no reason for supposing my brain to be composed of atoms.
J. B. S. Haldane
Kant was also quite aware that "the urgent need" of reason is both different from and "more than mere quest and desire for knowledge." Hence, the distinguishing of the two faculties, reason and intellect, coincides with a distinction between two altogether different mental activities, thinking and knowing.
Hannah Arendt
The evolutionary vision is agnostic in regard to systems in the universe of greater complexity than those of which human beings have clear knowledge. It recognizes aesthetic, moral, and religious ideas and experiences as a species, in this case of mental structures or of images, which clearly interacts with other species in the world's great' ecosystem.
Kenneth Boulding
It is almost as hard to define mathematics as it is to define economics, and one is tempted to fall back on the famous old definition attributed to Jacob Viner, "Economics is what economists do," and say that mathematics is what mathematicians do. A large part of mathematics deals with the formal relations of quantities or numbers.
