Short lived pleasure is the parent of pain.
Knowledge is power. Rather, knowledge is happiness, because to have knowledge -- broad, deep knowledge -- is to know true ends from false, and lofty things from low. To know the thoughts and deeds that have marked man's progress is to feel the great heartthrobs of humanity through the centuries; and if one does not feel in these pulsations a heavenward striving, one must indeed be deaf to the harmonies of life.
Museums and art stores are also sources of pleasure and inspiration. Doubtless it will seem strange to many that the hand unaided by sight can feel action, sentiment, beauty in the cold marble; and yet it is true that I derive genuine pleasure from touching great works of art. As my finger tips trace line and curve, they discover the thought and emotion which the artist has portrayed.
