Jonas Salk Quotes

Neither wisdom nor good will is now dominant. Hope lies in dreams, in imagination and in the courage of those who dare to make dreams into reality.

I have the impression that the new generation of young people, are coming up on the scene with a sense "ancestorhood", and with more wisdom than was evident before. I think this comes about as a matter of necessity — Almost as if there is something in us that is innate, something inherent in us, that is destined for a longer term, rather than a shorter term future.

When things get bad enough, then something happens to correct the course. And it's for that reason that I speak about evolution as an error-making and an error-correcting process. And if we can be ever so much better - ever so much slightly better - at error correcting than at error making, then we'll make it.

We were told in one lecture that it was possible to immunize against diphtheria and tetanus by the use of chemically treated toxins, or toxoids. And the following lecture, we were told that for immunization against a virus disease, you have to experience the infection, and that you could not induce immunity with the so-called "killed" or inactivated, chemically treated virus preparation. Well, somehow, that struck me. What struck me was that both statements couldn't be true. And I asked why this was so, and the answer that was given was in a sense, 'Because.' There was no satisfactory answer.

Know what is the purpose of life that you are inclined to serve, that you are drawn to. Do what makes your heart leap rather than simply follow some style or fashion. Not everyone can or should be a scientist. Not everyone can or should be any one thing. People need to know what kind of purpose they can serve.

Now, some people might look at something and let it go by, because they don't recognize the pattern and the significance. It's the sensitivity to pattern recognition that seems to me to be of great importance. It's a matter of being able to find meaning, whether it's positive or negative, in whatever you encounter. It's like a journey. It's like finding the paths that will allow you to go forward, or that path that has a block that tells you to start over again or do something else.

I was told I could, if I wished, switch and get a Ph.D. in biochemistry but my preference was to stay with medicine. And I believe that this is all linked to my original ambition, or desire, which was to be of some help to humankind, so to speak, in a larger sense than just on a one-to-one basis. Just as I intended to study law, to make just laws, so I found myself interested now in the laws of nature, as distinct from the laws the people make.

What you see in living systems, and in genetic systems, is that the genes are already there, having arisen in the course of time, and when they are needed they become activated. If they had to be invented, the time would be too late. By the same token, I think that the people who are needed to help guide the future already exist. They simply need to recognize this in themselves, react to the opportunities that prevail, and also be valued and be encouraged. It's that very large, and as yet amorphous, rung that is of interest to me. I hope to articulate this, and see to what extent it makes sense to others as well.

Some people are constructive, if you like. Others are destructive. It's this diversity in humankind that results in some making positive contributions and some negative contributions. It's necessary to have enough to make positive contributions to overcome the problems of each age.

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.

Our greatest responsiblity is to be good ancestors.

I have dreams, and I have nightmares. I overcame the nightmares because of my dreams.

I look upon ourselves as partners in all of this, and that each of us contributes and does what he can do best. And so I see not a top rung and a bottom rung — I see all this horizontally — and I see this as part of a matrix. And I see every human being as having a purpose, a destiny, if you like. And what my hope is that we can find some way to fulfill the biological potential, if you like — the destiny that exists in each of us — and find ways and means to provide such opportunities for everyone. Now at the moment the world is suffering from large numbers of people who have no purpose in life — for whom there is no opportunity — and that's sad.

Reply when questioned on the safety of the polio vaccine he developed:

It is safe, and you can't get safer than safe.

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. That's true of some. And I wouldn't guess as to what proportion. But there are some who are of that character, and there are some who are not.
