THE HIGHEST FUNCTION OF LOVE is that it makes the loved one a unique and irreplaceable being. The difference between love and logic is that in the eyes of a lover, a toad can be a prince, whereas in the analysis of a logistician, the lover would have to prove that the toad was a prince, an enterprise destined to dull the shine of many a passion. Logic limits love. 

The highest function of love is that it makes the loved one a unique and irreplaceable being. Still, lovers quarrel. Frequently, they quarrel simply to recharge the air between them, to sharpen the aliveness of their relationship.
