Thomas Malory Quote

Nowadays men cannot love seven night but they must have all their desires: that love may not endure by reason; for where they be soon accorded and hasty, heat soon it cooleth. Right so fareth love nowadays, soon hot soon cold: this is no stability. But the old love was not so.

Book XVIII, ch. 25 - Le Morte d'Arthur (c. 1469) (first known edition 1485)
