"The book, Apples Are Square: Thinking Differently About Leadership, presents the model of leadership necessary to move from the information age to the knowledge-based and ultimately, to a wisdom-based culture. The future depends on the survival of the wisest and on leadership that is based on inner values. Only leadership that enfolds the full potential of society will create true excellence for a new humanity."
