Famous quotes containing the words effective and/or duration:
“Social questions are too sectional, too topical, too temporal to move a man to the mighty effort which is needed to produce great poetry. Prison reform may nerve Charles Reade to produce an effective and businesslike prose melodrama; but it could never produce Hamlet, Faust, or Peer Gynt.”
—George Bernard Shaw (1856–1950)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
