“If he would just work with pure ideas like a proper mathematician he could go as fast as thought. As it happens, Alan has become fascinated by the incarnations of pure ideas in the physical world. The underlying math of the universe is like the light streaming in through the window. Alan is not satisfied with merely knowing that it streams in. He blows smoke into the air to make the light visible. He sits in meadows gazing at pine cones and flowers, tracing the mathematical patterns in their structure, and he dreams about electron winds blowing over the glowing filaments and screens of radio tubes, and, in their surges and eddies, capturing something of what is going on in his own brain. Turing is neither a mortal nor a god. He is Antaeus. That he bridges the mathematical and physical worlds is his strength and his weakness.”

“The man who works recognizes his own product in the world that has actually been transformed by his work. He recognizes himself in it, he sees his own human reality in it he discovers and reveals to others the objective reality of his humanity of the originally abstract and purely subjective idea he has of himself”

“He wished that the mathematics of the world were like the mathematics of the heart - then his equal love and hate would mean he felt nothing instead of double.”

“The mathematician does not study pure mathematics because it is useful; he studies it because he delights in it and he delights in it because it is beautiful.”

“There is at the back of every artist’s mind something like a pattern and a type of architecture. The original quality in any man of imagination is imagery. It is a thing like the landscape of his dreams; the sort of world he would like to make or in which he would like to wander, the strange flora and fauna, his own secret planet, the sort of thing he likes to think about. This general atmosphere, and pattern or a structure of growth, governs all his creations, however varied.”

“The impact hit her like a physical blow. He was..."Beautiful." Eyes of such pure undiluted blue it was as if some heavenly artist had crushed sapphires into his paints and then colored in the irises with the finest of brushes.”
