“It is common opinion among us in regard to beauty and wisdom that there is an honourable and a shameful way of bestowing them. For to offer one’s beauty for money to all comers is called prostitution; but we think it virtuous to become friendly with a lover who is known to be a man of honour. So is it with wisdom. Those who offer it to all comers for money are known as sophists, prostitutors of wisdom.”
Words spoken by Socrates to Antiphon in Memorabilia, 1.6.11.

“If all things are in common among friends, the most precious is Wisdom.”
As quoted in Giordano Bruno : His Life and Thought (1950) by Dorothea Waley Singer http://www.positiveatheism.org/hist/bruno03.htm#CH3
Context: If all things are in common among friends, the most precious is Wisdom. What can Juno give which thou canst not receive from Wisdom? What mayest thou admire in Venus which thou mayest not also contemplate in Wisdom? Her beauty is not small, for the lord of all things taketh delight in her. Her I have loved and diligently sought from my youth up.
