But I am not at issue in this book with sincere and genuine scholars, but with a vast and vague public opinion which has been prematurely spread from certain imperfect investigations, and which has made fashionable a false notion of the whole history of humanity. It is the whole vague notion that a monkey evolved into a man and in the same way a barbarian evolved into a civilised man and therefore at every stage we have to look back to barbarism and forward to civilisation.
