The belief that the world is getting worse, that we can't solve extreme poverty and disease, isn't just mistaken. It is harmful.

The work of Dr. Salk is in the highest tradition of selfless and dedicated medical research. He has provided a means for the control of a dread disease... by helping scientists in other countries with technical information; by offering to them the strains of seed virus... by welcoming them to his laboratory that they may gain a fuller knowledge... his achievement, a credit to our entire scientific community, does honor to all the people of the United States.

Fear of disease killed more men than disease itself.
