Letter to Dr. Robert Marcus

February 12, 1950

Einstein wrote this letter of condolence to a grieving father named Robert S. Marcus, whose son
had succumbed to polio a few days earlier.


Dr. Robert S. Marcus
World Jewish Congress
1834 Broadway
New York 23, N.Y.

Dear Dr. Marcus:

A human being is part of the whole, called by us “Universe,” a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest—a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion. Not to nourish the delusion but to try to overcome it is the way to reach the attainable measure of peace of mind.

With my best wishes,
sincerely yours,

Albert Einstein
