"We may have learned to fly like birds and swim like fish, but we have forgotten how to live like human beings. It seems we have to relearn that skill. How can we do this? It is only possible if we learn about ourselves. We have to subject ourselves to self-analysis. Why? Because it is not outer space, not the wind, not the ocean, not the seasons, nature or animals that are the cause of this world’s problems, but we human beings—our minds."
