I sat upon a promontory,
And heard a mermaid, on a dolphin's back,
Uttering such dulcet and harmonious breath,
That the rude sea grew civil at her song;
And certain stars shot madly from their spheres,
To hear the sea-maid's music.
I knew when seven justices could not take up a quarrel, but when the parties were met themselves, one of them thought but of an If, as, 'If you said so, then I said so;' and they shook hands and swore brothers. Your If is the only peacemaker; much virtue in If.
