Jonas Salk: I don’t think I shared it too much with others. I kept it pretty much to myself, and when I reached an age at which I could do something about it, then I did. So it was not suppressed or destroyed. In fact, it’s that curiosity that bursts in childhood, during the period of play and creativity that reveals what we’re trying to say. That’s the nature of the human being. That’s what is the nature of the human species, as distinct from other species, where we see this enormous creativity because we are responsible for all that has been created, beyond that which nature has done.
