 It goes without saying that Comte’s idea of sociology was very different from the current one. To ensure the positivity of their discipline, sociologists have been quick to renounce its coordinating function, also known as encyclopedic or architectonic function, which characterizes philosophy. With its place at the top of the scale, the sociology of the Course recapitulates the whole of knowledge, while the sciences that precede it are but one immense introduction to this final science. As a consequence, no one can become a sociologist without having had a solid encyclopedic education, one that has no place for economics or social mathematics, but, on the contrary, emphasizes biology, the first science that deals with organized beings. How far removed this is from today’s sociology curriculum!
