1 Once upon a time a famous art museum searched the world over for the best paintings it
could find. After a long search, the museum found a beautiful Old Master painting depicting youths and
maidens frolicking in a wood. The directors were only too glad to pay millions for this painting because
they were captivated by its beauty and elegance. How delightfully the maidens' hair and mouths were
drawn, how perfectly the hands and arms of the youths, how lifelike the bare feet on the forest floor.
But the curator of the museum was the happiest one of all, for he had now become guardian and
protector of a famous work by a famous painter. "Every time I look at that painting," he would say, "I
see new beauties and excellences. Just look at these leaves here, the sweep of the branches from this
tree, capturing just the hint of a breeze and seeming to vibrate with the music from the dance of the
youths and maidens in the clearing. My very soul resonates with the greatness of it all."
2 Needless to say, this wonderful painting was the most popular exhibit at the museum,
providing instruction and delight for thousands of visitors. Everyone, from the young child who could
barely walk to the old man who could barely walk, enjoyed its beauty frankly and openly or profited
from studying its color and arrangement. Children loved to see the happy figures kicking up their feet
with joy; the young people marveled at the freshness and beauty of the figures;those of mature years
stood astonished at the excellent technique that could present such a convincing vision; the old
remarked upon the feeling of cozy intimacy produced by the scene of innocent pleasure.
3 "This painting is almost too good to be true," remarked one visitor prophetically as he
purchased a print of it.
4 One day a horrible discovery was made: the painting was not a genuine Old Master after
all. It was a forgery. It had not been painted by the famous artist whose name was on it, and in fact it
had been painted within the last ten years. The museum directors and the curator were horrified and
consumed with shame. Immediately the painting was jerked from the walls of the museum and
ignominiously relegated to a basement storeroom. "We regret such an unfortunate imposition," the
curator told the museum's patrons. "This painting is not art; it is a tawdry fake.This painting is a lie."
5 At first the public was saddened to lose sight of such a popular painting, and a few mild
protests were raised, but eventually concern for the painting was pushed aside by other more pressing
concerns, and it was forgotten (as are all things no longer directly in front of us in this busy world) and
life continued.
6 Only the museum curator and an occasional junior staff member ever saw the painting
now, hanging in the dim light of the basement well away from public view. All that was heard of it was
the curator's occasional disparaging comment. "Every day I see new defects and ugliness in this
fraudulent outrage," he would say. "Just look how false the sun on the leaves looks, how phony is the
wisp of that girl's hair, how ugly the clouds there, and how awkward that boy's position in the dance.
How we were ever taken in by this obvious cheat is beyond me." And finally, shaking his head to show
his regret, he concluded, "What we did was foolish and shameful."

Give Me Liberty
Riches I hold in light esteem,
And love I laugh to scorn;
And lust of fame was but a dream,
That vanished with the morn.
And if I pray, the only prayer
That moves my lips for me
Is, ‘Leave the heart that now I bear
And give me Liberty!’
Yes, as my swift days near their goal,
T’is all that I implore.
In life and death a chainless soul,
With courage to endure.
