Fear and love

– Fear has furthered the universal knowl­edge of humanity more than love, for fear wants to discern who the other person is, what he can do and what he wants: to deceive oneself here would mean danger and disadvantage. Inversely, love has a secret impulse to see in the other as much of the beautiful as possible or to elevate the other as high as possible: for love to deceive itself here would mean pleasure and advantage – and so it does. 

Nietzsche, The Dawn 309
