Krishnachandra Bhattacharyya (1875-1947) was one of the most prominent philosophers in India in the first half of the 20th century. Subject as Freedom (1930) is almost universally regarded by those who study modern Indian philosophy as the most important philosophical treatise composed in India during the period of British occupation. It is a meticulous analysis of the structure of human subjectivity. Despite its importance and reputation, however, this book has been little read because of KC Bhattacharyya's unusual prose style and vocabulary. The present edition includes both his original text and a translation into more familiar contemporary philosophical English with some explanatory notes and a new introduction.
