——1963年6月25日在西德市政厅柏林墙前的演说
译文：人生百年，无论大小事，兴盛与衰败，都如同一场梦般转瞬即逝。
孤独是我们为出生付出的代价。
The man who believes that the secrets of the world are forever hidden lives in mystery and fear. Superstition will drag him down. The rain will erode the deeds of his life. But that man who sets himself the task of singling out the thread of order from the tapestry will by the decision alone have taken charge of the world and it is only by such taking charge that he will effect a way to dictate the terms of his own fate.
