A serious life, by definition, is a life one reflects on, a life one tries to make sense of and bear witness to. Truth in a memoir is achieved not through a recital of actual events; it is achieved when the reader comes to believe that the writer is working hard to engage with the experience at hand. What happened to the writer is not what matters; what matters is the large sense that the writer is able to make of what happened.

For the integrated human being there is no past: there is only the continual transformation of original experience.

Before I knew that I was Jewish or a girl I knew that I was a member of the working class. At a time when I had not yet grasped the significance of the fact that in my house English was a second language, or that I wore dresses while my brother wore pants, I knew--and I knew it was important to know--that Papa worked hard all day long.

The older I grow, the more I realize how unfit we are for relationships. We are all such antagonists. It's part of the human condition to be deeply unfaithful to constancy. I do believe that.

Whatever a scientist is doing - reading, cooking, talking, playing - science thoughts are always there at the edge of the mind. They are the way the world is taken in; all that is seen is filtered through an everpresent scientific musing.

Emotional sympathies just dry up and die as we change, and they are as mysterious in friendship as in love. It's a relationship like any other.

When the whole world is writing letters, it's easy to lap into the quiet within, tell the story of an hour, keep alive the narrating inner life. To be alone in the presence of one's thought is not a value, only a common practice.
