“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.”

Foreword (January 1960)
You Learn by Living (1960)
Context: One's philosophy is not best expressed in words; it is expressed in the choices one makes. In stopping to think through the meaning of what I have learned, there is much that I believe intensely, much I am unsure of. In the long run, we shape our lives and we shape ourselves. The process never ends until we die. And, the choices we make are ultimately our own responsibility.

Context: If you are a mountain climber or someone who enjoys the countryside or the forest, you know that forests are our lungs outside of our bodies. Yet we have been acting in a way that has allowed millions of square miles of land to be deforested, and we have also destroyed the air, the rivers, and parts of the ozone layer. We are imprisoned in our small selves, thinking only of some comfortable conditions for this small self, while we destroy our large self. If we want to change the situation, we must begin by being our true selves. To be our true selves means we have to be the forest, the river, and the ozone layer. If we visualize ourselves as the forest, we will experience the hopes and fears of the trees. If we don't do this, the forests will die, and we will lose our chance for peace. When we understand that we inter-are with the trees, we will know that it is up to us to make an effort to keep the trees alive.
