"This is not a book on economics or economic theory. I am not an economist. My expertise lies in international finance and money systems. This is why I have adopted here a whole systems approach to money. Whole systems take into account a broader, more comprehensive arena than economics does; it integrates not only economic interactions but also their most important side effects. This includes specifically in our case the effects of different money systems on the quality of human interactions, on society at large, and on ecological systems. In essence, money is a lifeblood flowing through ourselves, our society, our global human community, and should be acknowledged and treated consciously."
