"As in a tilled-field, when ploughed for corn, some flowers are found amongst it, and yet, though these posies may charm the eye, all this labour was not spent in order to produce them--the man who sowed the field had another object in view he gained this over and above it--so pleasure is not [the?] reward or the cause of virtue, but comes in addition to: nor do we choose virtue because she gives us pleasure, but she gives us pleasure also if we choose her."
— Seneca, Lucius Annaeus (c. 4 B.C. - A.D. 65)
(Book VII, Chapter ix, pp. 214-5)
