This book comprises three works on social & political philosophy. The Human cycle deals with the evolution of human society. The Ideal of Human Uuity examines the possible unification of the human race. War & Self-Determination covers the problem of war & the self-determination of nation of nations. “The individuals who will most help the future of humanity in the new age will be those who will recognise a spiritual evolution as the destiny & therefore need of the human being… They will especially not make the mistake of thinking that this [spiritual] change can be effected by machinery & outward institutions; they will know & never forget that it has to be lived out by man inwardly or it can be made a reality for the kind. They will adopt in its heart of meaning the inward view of the East which bids man seek the destiny & salvation within; but also they will accept, though with a different turn given to it, the importance which the West rightly attaches to life & to the making the best we know & can attain the general rule of all life.” THE CYCLE OF SOCIETY:- MODERN Science, obsessed with the greatness of its physical discoveries & the idea of sole existence of Matter, has long attempted to base upon physical data even its study of Soul & Mind & of thous workings of Nature in man & animal in which a knowledge of psychology is as important as any the phyiscal sciences. Its very psychology founded itself upon physiologh & the scrutiny of the brain & nervous system. Its very psychologh founded itself upon physiology & the scrutiny of the brain & nervous system. It is not surprising therefore that in history & sociologh attention should have been concentrated on the external data, laws, institutions, rites, customs, economic factors & developmants, while the deeper psychological elemants so important in the activities of a mental, emotional, ideative being like man have very much neglected. This kind of science would explain history & social development as much as possible by economic necessity or motive, – by economy understood in its widest sense. There are even historians who deny or put aside as of a very subsidiary importance the working of the idea & the influence of the thinker in the development of human institutions. The French Revolution, it is thought, would have happened just as it did & when it did & when it did, by economic necessity, even if Rousseau & Voltaire had never written & the eighteenth-century philosophic movement in the world of thought had never worked out its bold & radical speculations.
