Boston's Cardinal William Henry O'Connell said. This public blast from a Cardinal prompted the noted Orthodox Jewish leader in New York, Rabbi Herbert S. Goldstein, to send a very direct telegram: "Do you believe in God? Stop. Answer paid. 50 words." Einstein used only about half his allotted number of words. It became the most famous version of an answer he gave often: "I believe in Spinoza's God, who reveals himself in the lawful harmony of all that exists, but not in a God who concerns himself with the fate and the doings of mankind."
Einstein, on the other hand, believed - as did Spinoza - that a person's actions were just as determined as that of a billiard ball, planet or star. "Human beings in their thinking, feeling and acting are not free but are as causally bound as the stars in their motions," Einstein declared in a statement to a Spinoza Society in 1932. It was a concept he drew also from his reading of Schopenhauer. "Everybody acts not only under external compulsion but also in accordance with inner necessity," he wrote in his famous credo. "Schopenhauer's saying, 'A man can do as he wills, but not will as he wills,' has been a real inspiration to me since my youth; it has been a continual consolation in the face of life's hardships, my own and others', and an unfailing wellspring of tolerance."
But Einstein's answer was to look upon free will as something that was useful, indeed necessary, for a civilized society, because it caused people to take responsibility for their own actions. "I am compelled to act as if free will existed," he explained, "because if I wish to live in a civilized society I must act responsibly." He could even hold people responsible for their good or evil, since that was both a pragmatic and sensible approach to life, while still believing intellectually that everyone's actions were predetermined. "I know that philosophically a murderer is not responsible for his crime," he said, "but I prefer not to take tea with him."
