I have had the moral satisfaction of finding out that the anticipations expressed in my speech at the Nobel banquet have actually come true, to this extent: that the fact of being a Nobel Prize winner has enabled me to exert more influence in bringing to people the realization of the critical need for (1) increasing freedom of thought and expression on the part of all the peoples of the world, and (2) increasing their standard of living. These are fundamental to all other progress and to the avoidance of world disaster.
