“Science, my dears, is the systematic dissection of nature, to reduce it to working parts that more or less obey universal laws. Sorcery moves in the opposite direction. It doesn't rend, it repairs. It is synthesis rather than analysis. It builds anew rather than revealing the old. In the hands of someone truly skilled,...it is Art.”

“And just holding her hand would be good. Can you understand that? Do you know that holding someone's hand can be `the' thing? Such a thing that your hands move while not moving.

When everything is repeated, and over, and familiar, it's the first things rather than the last that count.”

“The universe looks more and more like a great thought rather than a great machine.”

“A difficult journey is more revealing of character than any discussion or analysis.”

“I would rather obey a fine lion, much stronger than myself, than two hundred rats of my own species.”
