"We often refuse to accept an idea merely because the tone of voice in which it has been expressed is unsympathetic to us."

"When marrying, ask yourself this question: Do you believe that you will be able to converse well with this person into your old age? Everything else in marriage is transitory."

"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."

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

Friedrich Nietzsche
