It may be that when we no longer know what to do, ...

We cannot know the whole truth, which belongs to God alone, but our task nevertheless is to seek to know what is true. And if we offend gravely enough against what we know to be true, as by failing badly enough to deal affectionately and responsibly with our land and our neighbors, truth will retaliate with ugliness, poverty, and disease.

It is a horrible fact that we can read in the daily paper, without interrupting our breakfast, numerical reckonings of death and destruction that ought to break our hearts or scare us out of our wits.

To be interested in food but not in food production is clearly absurd.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

Common sense is the collection of prejudices acquired by age eighteen.

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Wisdom doesn't necessarily come with age. Sometimes age just shows up all by itself.
