Of this book, H. G. Wells wrote:

"The World Set Free was written in 1913 and published early in 1914. It is the latest of a series of three fantasias of possibility, stories which all turn on the possible developments in the future of some contemporary force or group of forces. The World Set Free was written under the immediate shadow of the Great War. Every intelligent person in the world felt that disaster was impending and knew no way of averting it, but few of us realised in the earlier half of 1914 how near the crash was to us..."

The thesis of this story is that "because of the development of scientific knowledge, separate sovereign states and separate sovereign empires are no longer possible in the world. To attempt to keep on with the old system is to heap disaster upon disaster for [hu]mankind and perhaps to destroy our race altogether. The remaining interest of this book now is the sustained validity of this thesis and the discussion of the possible ending of war on the earth."
