Intellectual quest for World Order is as old as the history of mankind. Saints and sages, religious visionaries and philosophers from all great civilizations have left their valuable contributions on the peaceful sands of time. However much of this wealth has been obliterated by other events of history wherein power, might and grandeur were used as the instruments of exploitation by a section of human beings . Time has come to research on the past, and on its basis to analyze the present and visualize a future for a just world order. In World Constitutionalism, over two dozen scholars, academicians, administrators, and leaders of civil society have come together to pen their innovative ideas. It is an attempt to carry their vision over national barriers through the realms of Human Rights, Environmental Law, Feminist Justice, Global Democracy and so on . In the fast evolving twenty first century , World Constitutionalism is already exploding on the global scene in all fields of life , as human race finds enlightenment through information and networking revolution, technology development, and conscious spiritual awakening taking place from East to West. World Constitutionalism endeavours to foster scientific study of world governance as a multi disciplinary subject with an added flavour of law to give it special sanctity in the minds of the Peoples of the World. The book is an addition to the growing movement for World Unity that presently reechoes round the globe.
