I can dispel the clouds, drain the sea, or cure someone hopelessly ill. But to change the mind of a fool is beyond me.

The young people think the old people are fools — but the old people know the young people are fools.

"Folly is the only thing that keeps youth at a stay and old age afar off;" as it is verified in the Brabanders, of whom there goes this common saying, "That age, which is wont to render other men wiser, makes them the greater fools."

We need to realize that we are as young as our faith and as old as our doubts. We are also as young as our self-confidence and as old as our fears. We are as young as our hopes and as old as our despairs. We will develop faith, self-confidence and hope.

The surprising thing about young fools is how many survive to become old fools.

Well. You were allowed to be young and stupid, when you were young and stupid, and if it didn’t do you in, you might get older and wiser.

Years may wrinkle the skin, but to give up interest wrinkles the soul. You are as young as your faith, as old as your doubt; as young as your self-confidence, as old as your fear; as young as your hope as old as your despair. In the central place of every heart there is a recording chamber. So long as it receives messages of beauty, hope, cheer and courage, so long are you young. When your heart is covered with the snows of pessimism and the ice of cynicism, then, and then only, are you grown old. And then, indeed as the ballad says, you just fade away

A fool cannot be convinced or even compelled to renounce his folly.

[Thelma] "...We're too old to keep being foolish."

Fools are determined to be fools. Trying to stop them from being so is futile.

I understand you, and I shall not attempt to make you change your mind. I am too old to want to improve the world. I have told you what I think, and that is all. I shall remain your friend even if you act contrary to my convictions, and I shall help you even if I disagree with you.

I'm not young enough to know everything.

I'm not young enough to know everything.

Young men think old men are fools; but old men know young men are fools.
