Einstein, Albert. 1879-1955. German-born American physicist and Nobel laureate. "A human being is part of a whole, called by us the 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. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty. The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives. To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science."
