This work deals with the social and moral philosophy of Swami Vivekananda with special reference to his response to the ideas of Shankara and Ramanuja. The first two pieces deal with Swami Vivekananda's Vedantic Socialism and his Revolutionary Ideas. The themes of the remaining pieces are Swami Vivekananda and the Question of Unity, and his view of the philosophy of Shankara and Ramanuja.

Swami Vivekananda said that he was a socialist, though he did not think that socialism was perfect. He added, however, that half a loaf was better than none. But what kind of socialism did he have in view? That is not known. Here, in this book, Dr R. K. Das Gupta, the author and Vivekananda Professor of this Institute, has presented to us a new brand of socialism which he calls 'Swami Vivekananda's Vedantic Socialism.' The very title may sound absurd to many, but the author is serious and he knows what he is talking about. He anticipates all possible objections and meets them squarely. His contention seems to be that real socialism has to be Vedantic in the sense that Swami Vivekananda used the word. Anything short of that will be a misnomer. Socialism, no matter of what brand, can only be ushered in through a revolution. But in the case of Vedantic socialism, the revolution is not violent; it is instead a peaceful revolution of character.

The book is thought-provoking. Readers will find reading the book rewarding.
