They wouldn't let us into Russia. They thought we'd corrupt the youth or something.

The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they alone knew everything and what passes for wisdom with us is foolishness with them. As for girls, they are forward, immodest and unwomanly in speech, behaviour and dress.

I still live, I still think: I still have to live, for I still have to think.

We do not belong to those who only get their thought from books, or at the prompting of books. It is our custom to think in the open air, walking, leaping, climbing, or dancing on lonesome mountains by preference, or close to the sea, where even the paths become thoughtful.

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.

Profundity of thought belongs to youth, clarity of thought to old age.
