It remains a real world if there is a background to the symbols - an unknown quantity which the mathematical symbol x stands for. We think we are not wholly cut off from this background. It is to this background that our own personality and consciousness belong, and those spiritual aspects of our nature not to be described by any symbolism ... to which mathematical physics has hitherto restricted itself.

Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.
Heat, like gravity, penetrates every substance of the universe, its rays occupy all parts of space. The object of our work is to set forth the mathematical laws which this element obeys. The theory of heat will hereafter form one of the most important branches of general physics.
Joseph Fourier
The destiny of the spiritual World, and, - since this is the substantial World, while the physical remains subordinate to it, or, in the language of speculation, has no truth as against the spiritual, - the final cause of the World at large, we allege to be the consciousness of its own freedom on the part of Spirit, and ipso facto, the reality of that freedom.
Georg Wilhelm Friedrich Hegel
Philosophy is written in this grand book, which stands continually open before our eyes (I say the 'Universe'), but can not be understood without first learning to comprehend the language and know the characters as it is written. It is written in mathematical language, and its characters are triangles, circles and other geometric figures, without which it is impossible to humanly understand a word; without these one is wandering in a dark labyrinth.
Galileo Galilei
No mockery in this world ever sounds to me so hollow as that of being told to cultivate happiness. What does such advice mean? Happiness is not a potato, to be planted in mould, and tilled with manure. Happiness is a glory shining far down upon us out of Heaven. She is a divine dew which the soul, on certain of its summer mornings, feels dropping upon it from the amaranth bloom and golden fruitage of Paradise.
Charlotte Brontë
I conceived, developed and applied in many areas a new geometry of nature, which finds order in chaotic shapes and processes. It grew without a name until 1975, when I coined a new word to denote it, fractal geometry, from the Latin word for irregular and broken up, fractus. Today you might say that, until fractal geometry became organized, my life had followed a fractal orbit.
