"But you are not wise,
Or else you love not; for to be wise and love
Exceeds man's might. That dwells with gods above."
As far as I am aware, not a single critic has discerned the absolute necessity for the negative in this place. "The gods themselves cannot be wise and love" (Marston, Dutch Courtezan, ii. 1). Both dramatists were probably indebted to Spenser:—
"To be wise and eke to love
Is granted scarce to gods above."
