“But today our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change. The large house in which we live demands that we transform this world-wide neighborhood into a world – wide brotherhood. Together we must learn to live as brothers or together we will be forced to perish as fools.We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually.”

“When we look at modern man, we have to face the fact...that modern man suffers from a kind of poverty of the spirit, which stands in glaring contrast to his scientific and technological abundance; We've learned to fly the air like birds, we've learned to swim the seas like fish, and yet we haven't learned to walk the Earth as brothers and sisters...”

“One of the great liabilities of history is that all too many people fail to remain awake through great periods of social change. Every society has its protectors of status quo and its fraternities of the indifferent who are notorious for sleeping through revolutions. Today, our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change.”

“If we are to have peace on earth, our loyalties must become ecumenical rather than sectional. Our loyalties must transcend our race, our tribe, our class, and our nation; and this means we must develop a world perspective.”

“We must live together as brothers or perish together as fools.”

“Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”

“We must either learn to live together as brothers, or we are going to die together as fools.”
