“The created world is but a small parenthesis in eternity' something quite different, relating to the planet's life-span, not individual life-span.”

“The blink of an eye in itself is nothing. But the eye that blinks, that is something. A span of life is nothing. But the man who lives that span, he is something. He can fill that tiny span with meaning, so its quality is immeasurable though its quantity may be insignificant.”

“I learned a long time ago, Reuven, that a blink of an eye in itself is nothing. But the eye that blinks, that is something. A span of life is nothing. But the man who lives that span, he is something. He can fill that tiny span with meaning, so its quality is immeasurable though its quantity may be insignificant. Do you understand what I am saying? A man must fill his life with meaning, meaning is not automatically given to life.”

“When I consider the small span of my life absorbed in the eternity of all time, or the small part of space which I can touch or see engulfed by the infinite immensity of spaces that I know not and that know me not, I am frightened and astonished to see myself here instead of there … now instead of then.”

“...no-one is finally dead until the ripples they cause in the world die away... The span of someone's life, they say, is only the core of their actual existence.”

“With composition, parts can’t be shared with other objects. The life of the part is completely within the life span of the whole.”
