"To the civilized revolutionary, not a single human life is expendable, even that of the oppressor, whereas to the mindless terrorist, even the loss of innocent lives is acceptable in the pursuit of their mission." Abhijit Naskar, the scientist and reformer who has been at the forefront of humankind's struggle against discrimination and prejudice, delivers us a masterpiece on revolution, liberty and righteousness. He gives us the golden principle: "We are but each other's keeper."
