Herman Melville Quote

In placid hours well-pleased we dream Of many a brave unbodied scheme. But form to lend, pulsed life create, What unlike things must meet and mate: A flame to melt--a wind to freeze; Sad patience--joyous energies; Humility--yet pride and scorn; Instinct and study; love and hate; Audacity--reverence. These must mate, And fuse with Jacob's mystic heart, To wrestle with the angel--Art.

John Marr and Other Poems (ed. 1922)
