“They say that every snowflake is different. If that were true, how could the world go on? How could we ever get up off our knees? How could we ever recover from the wonder of it?”

Context: We could not guess how different from us they (extraterrestrials) might be. It was hard enough to guess the intentions of our elected representatives in Washington.

Generation of Greatness (1957)
Context: In thinking about what the human animal might have gone through in the evolutionary process, have you wondered how some of the small changes which must have occurred could have had survival value? Haven't you wondered how they could have survived, when, in all of our experimental work every small change we make dies? … How many changes must have occurred in the human eye, occurred and died, before one change came along — an apparently trivial change … that gave the whole animal a significant increase in its power to perceive and hunt down its enemies and find its food. This is the kind of change that survives.

Mohican Press interview (2005)
Context: There came a point in time, with all the difficulty, all the frustration, where I was quite content to be where I was. I suppose one could call it a kind of enchantment, I don't know. The shoot was so difficult on the crew and the extras. Often, it was unpleasant for them and many left. But difficulty also creates its own kind of beauty, I suppose. And while I don't revisit it unless asked, there is this sense of apartness I felt during that period of time from our own world. Perhaps the others felt the same, I'm unsure, and that is what you might feel when you watch the movie. We were all so different, temperamentally from one another, it's impossible to believe that we were together for so long. The cast and crew. How could we be more different from one another? It's difficult to imagine. But something lovely came of it.

Gli è ben vero che si dice Tu imparerai per un'altra volta: questo non vale perchè la vien sempre con modi diversi e non mai immaginati.
