“A country whose buildings are of wood, can never increase in its improvements to any considerable degree.... Whereas when buildings are of durable materials, every new edifice is an actual and permanent acquisition to the state, adding to its value as well as to its ornament.”
—Thomas Jefferson (1743–1826)
“The improvements of ages have had but little influence on the essential laws of man’s existence: as our skeletons, probably, are not to be distinguished from those of our ancestors.”
—Henry David Thoreau (1817–1862)
“In early days, I tried not to give librarians any trouble, which was where I made my primary mistake. Librarians like to be given trouble; they exist for it, they are geared to it. For the location of a mislaid volume, an uncatalogued item, your good librarian has a ferret’s nose. Give her a scent and she jumps the leash, her eye bright with battle.”
—Catherine Drinker Bowen (1897–1973)
“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
