Love is blind; friendship closes its eyes. - Friedrich Nietzsche

"A woman may very well form a friendship with a man, but for this to endure, it must be assisted by a little physical antipathy."

"A pair of powerful spectacles has sometimes sufficed to cure a person in love."

"Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you."

"It is not a lack of love, but a lack of friendship that makes unhappy marriages."

"Dove la moralità è troppo forte l'intelletto perisce."
