Early in the nineteenth century three am- bitious classifications were proposed, one by Ben- tham (181(>). one by Comte (18;{0). and one by A. M. Amp&re (1834). Rentham's and Ampere's agree in being dichotomous and characterized by highly artificial terminologies, which form one of the curiosities in the history of science. Both also agree in dividing the sciences into those dealing with body and those dealing with mind. The former Benthani calls somatol- ogy, and the latter pneumatology. Soma- tology is divided into posology (mathematics) or the science of pure quantify, an<l poiology or .£ 5 I ■! ^ * the science which deals with qualities.

I £=.s" Perhaps the best known and the most thori ^ i -^ * oughly discussed classification ever made is Comte's. The division is not by genus and spe- cies, but by hierarchical order. "The classifiea- goi^ tion." he says, '•must proceed from the study of a, -;2 I the things to be classified, and iinist by no means 5.9 = be determined by « priiiyi considerations. The •5 = J. § real afiiniHcs ami natural connections presented by objects being allowed to determine their or- der, the classification itself becomes the expres- sion of the most general fact. ... It fol- _, . lows that the mutual dependence of the sciences ^ — a dependence resulting from that of the corre- gg spending phenomena — must determine the ar- Egu rangement of the system of human knowledge." Applying this method. Comte concludes tiiat there are six sciences. "We cannot make them less;
