Quotation of the day

From Al-Biruni
Once a sage asked why scholars always flock to the doors of the rich, whilst the rich are not inclined to call at the doors of scholars. "The scholars" he answered , "are well aware of the use of money, but the rich are ignorant of the nobility of science".
Quoted in A L Mackay, Dictionary of Scientific Quotations (London 1994)
