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.

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.

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.

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.

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.

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