Young people love what is interesting and odd, no matter how true or false it is. More mature minds love what is interesting and odd about truth. Fully mature intellects, finally, love truth, even when it appears plain and simple, boring to the ordinary person; for they have noticed that truth tends to reveal its highest wisdom in the guise of simplicity.
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.
Curiosity, or the love of knowledge, has a very limited influence, and requires youth, leisure, education, genius and example to make it govern any person.
Something there is that can refresh and revivify older people: joy in the activities of the younger generation -- a joy, to be sure, that is clouded by dark forebodings in these unsettled times. And yet, as always, the springtime sun brings forth new life, and we may rejoice because of this new life and contribute to its unfolding; and Mozart remains as beautiful and tender as he always was and always will be. There is, after all, something eternal that lies beyond the hand of fate and of all human delusions. And such eternals lie closer to an older person than to a younger one oscillating between fear and hope. For us, there remains the privilege of experiencing beauty and truth in their purest forms.
In old age our bodies are worn-out instruments, on which the soul tries in vain to play the melodies of youth. But because the instrument has lost its strings, or is out of tune, it does not follow that the musician has lost his skill.
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.
Crabbed age and youth cannot live together: Youth is full of pleasure, age is full of care; Youth like summer morn, age like winter weather; Youth like summer brave, age like winter bare.
The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently.

Whoever, in middle age, attempts to realize the wishes and hopes of his early youth, invariably deceives himself.
In old age our bodies are worn-out instruments, on which the soul tries in vain to play the melodies of youth. But because the instrument has lost its strings, or is out of tune, it does not follow that the musician has lost his skill.
The young do not know enough to be prudent, and therefore they attempt the impossible, and achieve it, generation after generation.
