Concrete Operational Stage

Famous quotes containing the words concrete and/or stage:

“Total loyalty is possible only when fidelity is emptied of all concrete content, from which changes of mind might naturally arise.”
—Hannah Arendt (1906–1975)

“The post-office appeared a singularly domestic institution here. Ever and anon the stage stopped before some low shop or dwelling, and a wheelwright or shoemaker appeared in his shirt- sleeves and leather apron, with spectacles newly donned, holding up Uncle Sam’s bag, as if it were a slice of home-made cake, for the travelers, while he retailed some piece of gossip to the driver, really as indifferent to the presence of the former as if they were so much baggage.”
—Henry David Thoreau (1817–1862)
