It is barely possible that the purpose and design of Comte's Classification had, unconsciously, much to do with its really unscientific and incongruous character. The aim which he had in view was to construct a Sociology or Science of Society which should be a guide in the establishment of a new Government, a new Political Economy, a new Religion, a new Social Life, a new Order of Things, in fine, to take the place of the decrepit institutions, governmental, ecclesiastical, and social, which he thought were fast approaching their period of dissolution. The Generalization which had exhibited to him, that the Laws and Phenomena of the various departments of investigation were dependent on each other in a graduated scale, and had thus enabled him to establish the _Hierarchy of the Sciences_, showed him that Sociology, including as it does the Principles and Phenomena of the other domains which he regards as Positive Sciences, must be based upon them. Hence it became necessary to fix the Scientific character of all these branches of intelligence, in order to create a Scientific basis for his Sociology. It was, however, impossible for him to claim that a Demonstrable or Infallible method of Proof was applicable to Chemistry and Biology; while, on the other hand, to exhibit such a method as introducing a certainty into Mathematics, Astronomy, and Physics which did not appertain to the other so-called Positive Sciences, would have indicated too plainly the unspanned gulf which yawned between the indubitable Demonstrations of the Exact Sciences and the merely probable Generalizations of the others, and have exposed the fallible character of his Sociological theories. A Classification was rendered indispensable, therefore, which should display uniformity in its character, and a sufficiently rigorous mode of Scientific proof. To fulfil this end, the Inexact Sciences were accorded a position of _certainty_ in reference to their Principles which does not in reality belong to them; while the Exact or Infallible Sciences were degraded from their peculiarly high state, and brought to the new level of the former on the middle ground of the Positive Philosophy. A quasi-Scientific basis was thus erected for the Sociological movements of the French Reformer.
