In my younger days I was perplexed by the mystery of whether the many species of life originated by evolution, as my school books said, or by separate creation, as my church said. This led me to the mystery of how one answers such a question. In tackling those two mysteries, I realize I was choosing between two world views. I was choosing the possibility of advancement instead of idealization of the past; I was choosing progressive change instead of quick fixes; I was choosing the ability of any individual to learn and con-tribute, instead of submitting to authority. And I have found grandeur in this view of life.
