Three works of social and political philosophy.

In The Human Cycle, Sri Aurobindo traces the evolution of human society and suggests where it is headed. In The Ideal of Human Unity, he examines the possibility of the unification of the human race. In War and Self-Determination, he discusses the sovereignty of nations in the aftermath of the First World War. These works were first serialised in the monthly review Arya between 1915 and 1920; later Sri Aurobindo revised them for publication.
