“If we look at the reality of the world from the viewpoint of the industrial era, it is clear that there is no hope But there is another way to look at our situation. We can discover the large number of people who have decided to change. … If we do this, it seems equally impossible that we shall fail to solve our problems.”

Donovan: "We are all one shining Being" (1998)
Context: When I was 14 or 15 I wanted to be a protest singer like Pete Seeger and Woody Guthrie. My father was a socialist and worked with the unions. I thought change was to change the government and to change from one system, capitalism, to socialism and to make the poor of the world happy. But when I opened the book The Way of Zen by Alan Watts and I opened up the Diamond Sutra, and Lao Tsu’s Tao Te Ching, I realized that the problem of suffering was much deeper than governments and social problems. The problems were very deep. They were nothing short of changing the way we look at reality. Therefore I became a teacher, or a reflection of the teachings. Phil Ochs, the great protest singer, said I had given up protest, and Joan Baez said to Bob Dylan, “He’s given up protest.” But what I had given up was looking for the answer in social change. The change was to be a spiritual change. The suffering was coming from an erroneous view of reality...

1960, The New Frontier
Context: For the harsh facts of the matter are that we stand on this frontier at a turning-point in history. We must prove all over again whether this nation — or any nation so conceived — can long endure — whether our society — with its freedom of choice, its breadth of opportunity, its range of alternatives — can compete with the single-minded advance of the Communist system. Can a nation organized and governed such as ours endure? That is the real question. Have we the nerve and the will? Can we carry through in an age where we will witness not only new breakthroughs in weapons of destruction — but also a race for mastery of the sky and the rain, the ocean and the tides, the far side of space and the inside of men's minds? Are we up to the task — are we equal to the challenge? Are we willing to match the Russian sacrifice of the present for the future — or must we sacrifice our future in order to enjoy the present? That is the question of the New Frontier. That is the choice our nation must make — a choice that lies not merely between two men or two parties, but between the public interest and private comfort — between national greatness and national decline — between the fresh air of progress and the stale, dank atmosphere of "normalcy" — between determined dedication and creeping mediocrity. All mankind waits upon our decision. A whole world looks to see what we will do. We cannot fail their trust, we cannot fail to try.
