international law is the precursor of international government, and international government is nothing more than an intensification of international law. Similar to international society, international law has constantly evolved from its inception. There is no reason to believe that its evolution has ceased. Similar to natural evolution, the evolution of international law responds to changing conditions. This book thus claims that international law evolves functionally: it changes as its constituents determine new uses. The new uses evolve with factors such as globalization, development, demography, technology and democratization, as well as with our understanding of our situation.
