The really intelligent person keeps his childhood alive to his last breath.He never loses it-the wonder the child feels looking at the birds,looking at the flowers,looking at the sky...Intelligence also has to be,in the same way,childlike.

In the woods too, a man casts off his years, as the snake his slough, and at what period soever of life, is always a child. In the woods, is perpetual youth.
