The Paleolithic hunters who painted the unsurpassed animal murals on the ceiling of the cave at Altamira had only rudimentary tools. Art is older than production for use, and play older than work. Man was shaped less by what he had to do than by what he did in playful moments. It is the child in man that is the source of his uniqueness and creativeness, and the playground is the optimal milieu for the unfolding of his capacities.

All leaders strive to turn their followers into children.

It is the child in man that is the source of his uniqueness and creativeness, and the playground is the optimal milieu for the unfolding of his capacities and talents.

Children, savages and true believers remember far less what they have seen than what they have heard.

Call not that man wretched, who whatever ills he suffers, has a child to love.

The misery of a child is interesting to a mother, the misery of a young man is interesting to a young woman, the misery of an old man is interesting to nobody.
