 To bring out this eminent place of sociology is the principal aim of the General Conclusions of the Course. The 58th lesson raises the question of which science presides over the others on the encyclopedic scale. To guarantee the harmonious development of the various sciences taken together, the dominance of one among them has to be assumed. Until recently, that role had been played by mathematics, but ‘it will not be forgotten that a cradle is not a throne’ (1830 (58), v. 2, 718; E., v. 2, 510) (Bourdeau 2004). One should distinguish the first blossoming of the positive spirit from its systematic development. The human point of view, that is to say, the social point of view, is the only one that is truly universal; now that sociology is born, it is up to it to be in charge of the development of knowledge.
