ABSTRACT
If people are at all musical, then one might think of the pleasing sounds that come from a certain combination of notes, or even of the harmonics that are so important to the richness of the sounds we hear. Or, thinking of St Francis of Assisi, it might be the sort of harmony that seeks to displace discord, or the harmony we associate with tranquility and peace when we speak of living in harmony with our neighbours, or of getting along. People might knows that in 2009, the United Nations proclaimed 22 April as International Mother Earth Day. The Prince and his co-authors say that Harmony is a practical guide to what we have lost in the modern world, why we have lost it, and how we might rediscover it. Harmony looks at how many of the world's challenges can be traced to how we have abandoned a "sense of balance and proportion,".
