Book excerpt: This book aims to celebrate the many contributions of Professor Tommy Koh as a Singaporean diplomat, public intellectual and social changemaker.It is an account of the ideas and ideals of an extraordinary Singaporean public servant who was not only born with the talent and ability to traverse many areas of society, but one who, when given the opportunity, had the drive and ambition to make the most of it to create a better world for Singaporeans and the global community.Experts in the various fields of endeavour and people who have worked with him examine his significant contributions in essays that are organised in four main sections: Diplomacy and International Relations; Arts, Culture and Heritage; Progressive Society; International Law; and a fifth section that features tributes contributed by his colleagues and former classmates.Set in the context of Singapore — a nation known for its socio-economic progress, its ability to punch above its own weight in international relations, as well as its increasing appreciation for heritage, the arts, and sustainable development — this book illustrates the power of the individual and sense of agency that can create the systems and structures to achieve all those things. The story of Professor Tommy Koh as captured in this book should energise other change agents to go out and create the progressive, inclusive and sustainable world they want.An inspirational collection for general readers, this book reflects the spirit of Singapore's pioneer generation whose determination and tenacity turned the nation into the modern-day miracle that Singapore is today.
