Work and Potential Energy

“If work and leisure are soon to be subordinated to this one utopian principle—absolute busyness—then utopia and melancholy will come to coincide: an age without conflict will dawn, perpetually busy—and without consciousness.”

—Ralph Waldo Emerson (1803–1882)
“The traditional American husband and father had the responsibilities—and the privileges—of playing the role of primary provider. Sharing that role is not easy. To yield exclusive access to the role is to surrender some of the potential for fulfilling the hero fantasy—a fantasy that appeals to us all. The loss is far from trivial.”
—Faye J. Crosby (20th century)
“Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.”
—Elaine Heffner (20th century)
