For Epitcio Rodrigues the French philosopher August Comte (1798-1857), living in a period where the ideals of social reform were very present in the speeches of intellectuals as Saint Simon, of who he was secretary for a time, it innovates when defending that the organization or social order rests on a system of beliefs and ideas, that is, in an intellectual system. Thus, the intellectual or philosophical reform if becomes necessary condition of possibility of a social reform (Cf. CORDON, 1983, P. 23). In other terms, without a change of system in the ideas, it will not have revolution politics. From this constatao, Augustus Comte develops a true structuralized philosophical system at three basic moments: the first one is a philosophy of the history, in which it looks for to elucidate the development of the human spirit to justify the positive philosophy; the other characterizes for the recital and classification of sciences; e, finally, presents sociology as capable science of to determine the structure and the processes of social reform, by means of the transformation of the institutions.
It was also intention of Comte to proceed to a religious reform or to establish a new religion. (GIONNOTTI in: COMTE, 1996, P. 8) In the first part of its thought, Augustus Comte if strengthens to justify the positive philosophy historically, leaving of a consideration in which it conceives ' ' the history of the society as being over all dominated for the history of the spirit humano' ' (CORDON, 1983, P. 27). This means that history, while social order and progress of the society, is the result and the manifestation of the progress of the human intellect; thus, its philosophy of history is, in last instance, the history of the progress of the human spirit. Conveniently to explain the true nature and the proper character of the positive philosophy, it is indispensable to have, of beginning, a general vision on the gradual march of the human spirit, considered in its set, therefore a conception any only can well be known by its history.
