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.

All important progress made by the human race has its roots in daydreaming.

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.

It is strange but true that although we may have learned all sorts of important facts while raising our own children, when we become grandparents we still tend to forget a whole lot of things we knew.

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

One can develop new capacities and strengths with which to meet the natural vicissitudes of living; that one may gain a sense of inner peace through greater self-acceptance, through a more realistic perspective on one's relationships and experiences.

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.
