Don't be afraid to face the facts, and never lose your ability to ask the questions: Why? and How?

When I was a child of six or seven my father would show me the chapter in the prophet Isaiah where the name Immanuel is found; more than once he spoke to me of the faith he put in me.

My earliest memory is dreamlike: in a small orchard or garden I am carried on the arm, I believe, of my father; there was a group of grown-ups, my mother among them, and the group was slowly walking in the orchard, it seems toward the house.

My father felt that his world of ideas was too liberal for traditional rabbinical teachings, and he looked for a chance to find a way in life.

My first name - I have no middle name - was chosen by my father, as he told me, on that solitary walk in the forested hills. He selected it from a verse of the seventh chapter of Isaiah; there was no Immanuel among our ancestors known to him.

It is difficult to describe in short the enthusiasm and devotion provoked by and given to my research. We lived almost in poverty. I used pencils, two for a nickel, and could not buy a fountain pen, when I lost mine.
