Edward de Bono died on June 9th

THE LETTER was unexpected, but not undeserved. It contained an invitation to a Symposium in Athens. Over the years Edward de Bono had been to hundreds of these affairs. Some were seminars, some consultations or lecturing, all based on his much-acclaimed books. He had produced 70 of them, including “How To Be More Interesting”, “How To Have a Beautiful Mind”, “Edward de Bono’s Textbook of Wisdom” and “Think! Before It’s Too Late”. That last was the message he carried loud and clear as he jetted from city to city and boardroom to boardroom. He was teaching the world a new way of thought, the most important for 2,300 years.
