“To a person uninstructed in natural history, his country or sea-side stroll is a walk through a gallery filled with wonderful works of art, nine-tenths of which have their faces turned to the wall. Teach him something of natural history, and you place in his hands a catalogue of those which are worth turning round.” —Thomas Henry Huxley (1825–95)
“Each morning the manager of this gallery substituted some new picture, distinguished by more brilliant or harmonious coloring, for the old upon the walls.” —Henry David Thoreau (1817–1862)
“I never can pass by the Metropolitan Museum of Art in New York without thinking of it not as a gallery of living portraits but as a cemetery of tax-deductible wealth.” —Lewis H. Lapham (b. 1935)
