Although Auguste Comte is conventionally acknowledged as one of the founders of sociology and as a key representative of positivism, few new editions of his writings have been published in the English language in this century. He has become virtually dissociated from the history of modern positivism and the most recent debates about it. Gertrud Lenzer maintains that the work of Comte is, for better or for worse, essential to an understanding of the modern period of positivism. This collection provides new access to the work of Comte and gives practitioners of various disciplines the possibility of reassessing concepts that were first introduced in Comte's writings.
