Johannes Quack, in his preface to the book "Indian Atheism: A Marxist Analysis", writes, "This book is based on the awareness that the Indian struggle for socialism today is related to the struggle for the Indian philosophical heritage." Chattopadhaya is, he says, convinced that an analysis of philosophical materials of India will lead, "if rightly followed," to Marxism in India. He calls the book the "most powerful ideological weapon" to "destroy the fiction of Indian wisdom being essentially God oriented.". Reviewing the same book Dale Riepe calls it the most complete study of its kind; "its special importance lies in its iconoclasm toppling the idols of European and Indian accounts of early Indian religion and philosophy". He notes that the book ends with "another 140 pages of text with staggering load of argument that will make rationalists and theists alike somewhat dizzy". Noticing that Chattopadhyaya's book is markedly different from the mainstream scholarship on Indian philosophy he calls it "a work almost unique in the history of Indian philosophy".
