Some people are constructive, if you like. Others are destructive. Its — Jonas Salk

"My life is pretty well at peace, and the profession is more of an avocation. Its a calling, if you like, rather than a job. I do what I feel impelled to do, as an artist would. Scientists function in the same way. I see all these as creative activities, as all part of the process of discovery. Perhaps thats one of the characteristics of what I call the evolvers, any subset of the population who keep things moving in a positive, creative, constructive way, revealing the truth and beauty that exists in life and in nature."

"My attitude was always to keep open, to keep scanning. I think thats how things work in nature. Many people are close-minded, rigid, and thats not my inclination."

"You have to develop a thick skin in life. Its not in this field only. You might think of the ideal of the scientists, the ivory tower, the idealist. Thats true of some. And I wouldnt guess as to what proportion. But there are some who are of that character, and there are some who are not."

"I judge things from an evolutionary perspective — "How does this serve and contribute to the process of our own evolution?" — rather than think of good and evil in moral terms. I see the triumph of good over evil as a manifestation of the error-correcting process of evolution."

"Richard Heffner: You say "We can create ourselves and our future" Salk: — by shaping our selves not our cells — thats the important distinction. … We are shaping our cells, but we will not change our selves in the course of shaping our cells."

"Since whatever we do has to be part of a team, part of a community, we have to attempt to bring together those who have the same conviction, see the same things. Then it becomes a matter of time, when one or the other will prevail. Fortunately, there is all this diversity, and if not for that, problems would not be solved."

"I say this to you because we Spaniards are a forgetful people, because we are used to living for the moment, because we do not look back, because we do not know how to see the chain of heroes, because we do not contemplate the sum of sacrifices."

"If it fulfills our hopes, this center will be, at once, a symbol and a reflection and a hope. It will symbolize our belief that the world of creation and thought are at the core of all civilization. Only recently in the White House we helped commemorate the 400th anniversary of Shakespeare. The political conflicts and ambitions of his England are known to the scholar and to the specialist. But his plays will forever move men in every corner of the world. The leaders that he wrote about live far more vividly in his words than in the almost forgotten facts of their own rule. Our civilization, too, will largely survive in the works of our creation. There is a quality in art which speaks across the gulf dividing man from man and nation from nation, and century from century. That quality confirms the faith that our common hopes may be more enduring than our conflicting hostilities. Even now men of affairs are struggling to catch up with the insights of great art. The stakes may well be the survival of civilization. The personal preferences of men in government are not important--except to themselves. However, it is important to know that the opportunity we give to the arts is a measure of the quality of our civilization. It is important to be aware that artistic activity can enrich the life of our people, which really is the central object of Government. It is important that our material prosperity liberate and not confine the creative spirit."

"There was a man and he had eight sons. Apart from that, he was nothing more than a comma on the page of History. Its sad, but thats all you can say about some people."

"Children must be free to think in all directions irrespective of the peculiar ideas of parents who often seal their childrens minds with preconceived prejudices and false concepts of past generations. Unless we are very careful, very careful indeed, and very conscientious, there is still great danger that our children may turn out to be the same kind of people we are."

"I hear people say I swing at bad pitches. What is a bad pitch? If I can hit it, its not a bad pitch."

"A free people will always refuse to put up with preventable poverty. If freedom is to be saved and enlarged, poverty must be ended. There is no other solution. The problem of how to prevent these three forces from coming into head-on collision is the principal study of the more politically conscious Conservative leaders. How can wealth persuade poverty to use its political freedom to keep wealth in power? Here lies the whole art of Conservative politics in the twentieth century."
