James Wood, comp. Dictionary of Quotations. 1899.
Suckling
Joy never feasts so high as when the first course is of misery.
Love that can flow, and can admit increase, / Admits as well an ebb, and may grow less.
’Tis expectation makes a blessing dear; / Heaven were not heaven if we knew what it were.
True love is still the same; the torrid zones, / And those more rigid ones, / It must not know; / For love grown cold or hot / Is lust or friendship, not / The thing we show.
