The aim of this book is to persuade the reader that the Indian caste system is not the isolated phenomenon it is often thought to be. But a species of a very widespread genus. Not being an isolated phenomenon, it cannot be understood in isolation; it will merely be misunderstood. More than once it will be shown in these pages how localised specialism leads why from the truth and comparative study returns to it. Comparison also saves time by cutting the tangled knots which controversy ties round texts.
