This is the world out of which grows the hope, for the first time in history, of a society where there will be freedom from want and freedom from fear. Our very anxiety is born of our knowledge of what is now possible for each and for all. The number of people who consult psychiatrists today is not, as is sometimes felt, a symptom of increasing mental ill health, but rather the precursor of a world in which the hope of genuine mental health will be open to everyone, a world in which no individual feels that he needs be hopelessly broken-hearted, a failure, a menace to others or a traitor to himself. But if our anxieties are actually signs of hope, why is there such a voice of discontent abroad in the land? I think this comes perhaps because our anxiety exists with accompanying recognition of the tragedy which will always be inherent in human life, however well we build our world. We may banish hunger, violence and secret police, we cannot—as we have tried to do—banish death itself.

Einstein was one of the intellectual heroes of history, and such heroes, like Newton and like Darwin, are always twofold — rebels in their work and heretics in society. He prized the integrity of man's personality more highly than man's science. Back in the 1920's he said, in some desultory interview, that two discoveries might destroy mankind: atomic energy and universal thought-reading. The wry prophecy sums up Einstein's passions. He saw deeply into nature, her promise and her threat, but he was not too abstracted to remember .the fallibility of men. For him the key to the world lay in the minds of men. He fought for freedom of the mind from his rebellious school-days and the manifesto of 1914 to his dying day. In his last years he spoke out constantly against the inquisition which then darkened America. But even his love for science and for freedom was not abstract. These were for him the high places of the human mind, and he lived those; he loved people.
His richness of sympathy made him a symbol to an age. It carried his ideas beyond their scientific setting so that, more profoundly than the work of any philosopher, they changed the outlook of philosophy. All his ideas grew from one conception: that the world is not given to us absolutely, but is something which we actively observe and thereby shape. For Einstein was a practical thinker; to him, truth was that which is experienced in action. When he died, on April 18, 1955, Einstein had created a new empiricism, as revolutionary and as lasting as that with which Galileo laid the foundation of science.
