The moral and spiritual labor has also three objects: 1, the administration of justice in the State; 2, the theoretic culture of intelligence; 3, the moral culture of the will. Hence three classes: 1, =public functions=; 2, =science and instruction=; 3, =the Church and the clergy=. Lastly, there is in human nature a faculty which serves as a link between the theoretical and the practical faculties: it is the _esthetic sense_; the sense of the beautiful; hence a last class, that of =artists=. This theory is more scientific than that of the Saint-Simonians, but it is still somewhat defective; it is not clear, for example, in a moral point of view, that there is a great difference of duties between the producers, manufacturers, and merchants: they are economical rather than moral distinctions. Plato's division is better, when he puts the farmers in opposition to the artisans. It is certain that there are, especially in these days, interesting moral questions, which differ according as the workmen live in the city or in the country. We therefore prefer on this point Plato's division; and we will treat, on the one side, _industry_ and _commerce_, and on the other _agriculture_; and in each of these divisions we will distinguish those who direct or remunerate the work, namely, contractors, masters, proprietors, capitalists in some degree, and those who work with their hands and receive wages. In characterizing the second class of careers, those which have moral interests for their object, we will again borrow of Plato one of the names of his division, namely, _the defense of the State_. As to the administration of justice in the State, it is divided, as we have already said, into three powers: the _executive_, _legislative_, and _judicial_ powers. Hence three orders of functions: _administration_, _deputation_, and the _magistracy_, with which latter is connected the _bar_. As to science, it is either _speculative_ or _practical_. In the first case, it only concerns the individual; we have spoken of it under individual duties (ch. iv.). In the second case, it has for its object _application_, and bears either on _things_ or on _men_. Applied to things, science is associated with the industry we have already spoken of. Applied to men, it is _medicine_, in respect to bodies; _morality_ or _religion_, in respect to hearts and souls. Lastly, along with the sciences which seek the true, there are the letters and the arts which treat of and produce the beautiful. Hence a last class, namely, _poets_, _writers_, _artists_. Such is about the outline of what a system of social professions might be. A treatise of professional morality which would be in harmony with this outline, would be all one science, the elements of which scarcely exist, being dispersed in a multitude of works, or rather in the practice and interior life of each profession. We will content ourselves with a few general indications.
