Excellence in life seems to me to be the way in which each human being makes the most of the adventure of living and becomes most truly and deeply himself, fulfilling his own nature in the context of a good life with other people.

Every time a child is born, we have another chance.

We found ... that being a good parent to one's own child was never and in no way enough; until we were all responsible for all the children of the world, no child would ever be safe, no society could survive.

Until every individual feels personally responsible for the careful planning and the preservation of natural resources, the inexorable destruction will go on.

most of us carry into marriage not only our childlike illusions, but we bring to it as well the demand that it has to be wonderful, because it's supposed to be.

If I have learned anything in long years of introspection, it is that life requires a price if you want to be as fully alive as you can be. You need courage to pursue the truth of your life and yourself.

... no man can be psychologically castrated without his co-operation!
