“I’m afraid of everything. Fear of being alone, fear of being hurt, fear of being made a fool of, fear of failure… Still, I think all my fears bleed from one big one…”

Letter to Eileen Danniheisser (1953), quoted in Albert Einstein: Creator and Rebel by Banesh Hoffman (1973), p. 261 http://books.google.com/books?id=sdDaAAAAMAAJ&q=%22think+with+fear%22#search_anchor. The exact date, or the name of his correspondent, is not given in the snippet of the book available online, but the quote appears after the letter to the Queen of Belgium from 12 January 1953, and is prefaced by "Nine months later, in words that recall the beliefs of an early atomic speculator, the Roman poet Lucretius, Einstein had written to an inquirer", followed by the quote. The name "Eileen Danniheisser" is given in Time: Volume 144, where it is mentioned in the snippets here http://books.google.com/books?id=JDAnAQAAIAAJ&q=%22obsessive+thoughts%22#search_anchor and here http://books.google.com/books?id=JDAnAQAAIAAJ&q=%22think+with+fear%22#search_anchor that she had written Einstein "about her obsessive thoughts of death as a child".

2000s, To Live Beyond Our Fear (2007)
Context: Barack and I talked long and hard about this decision. You know, this wasn’t an easy decision for us, because we’ve got two beautiful little girls, and we have a wonderful life, and everything was going fine. And there was nothing that would have been more disruptive than a decision to run for President of the United States.
And as more people talk to us about it, I mean the question came up again and again. What people were most concerned about: they were afraid. It was fear. Fear, again, raising its ugly head, in one of the most important decisions we would make. Fear; fear of everything. Fear that we might lose. Fear that he might get hurt. Fear that this would be ugly. Fear that it would hurt our family. Fear.
But you know, the reason why I said yes was because I was tired of being afraid. I am tired of living in a country where every decision that we’ve made over the last ten years wasn’t for something, but it was because people told us we had to fear something. We had to fear people who looked different from us. Fear people who believed in things that were different from us. Fear of one another right here in our own backyards.
I am so tired of fear. And I don’t want my girls to live in a country, in a world, based on fear.

Je me presse de rire de tout, de peur d'être obligé d'en pleurer.
Act I, scene ii
Variant translations:
