(1) The Idea of inner freedom compares the will with the judgment, the conviction, the conscience of the agent himself. The agreement of his desire with his own judgment, with the precept of his taste, pleases, lack of agreement displeases. Since the power to determine the will according to one’s own insight of itself establishes only an empty consistency and loyalty to conviction, and may also subserve immoral craft, the first Idea waits for its content from the four following.
(2) The Idea of perfection has reference to the quantitative relations of the manifold strivings of a subject, in intensity, extension, and concentration. The strong is pleasing in contrast with the weak, the greater (more extended, richer) in contrast with the smaller, the collected in contrast with the scattered; in other words, in the individual desires it is energy which pleases, in their sum variety, in the system co-operation. While the first two Ideas have compared the will of the individual man with itself, the remaining ones consider its relation to the will of other rational beings, the third to a merely represented will, and the last two to an actual one.
(3) According to the Idea of benevolence or goodness, which gives the most immediate and definite criterion of the worth of the disposition, the will pleases if it is in harmony with the (represented) will of another, i.e., makes the satisfaction of the latter its aim.
(4) The Idea of right is based on the fact that strife displeases. If several wills come together at one point without ill-will (in claiming a thing), the parties ought to submit themselves to right as a rule for the avoidance of strife.
(5) In retribution and equity, also, the original element is displeasure, displeasure in an unrequited act as a disturbance of equilibrium. This last Idea demands that no deed of good or evil remain unanswered; that in reward, thanks, and punishment, a quantum of good and evil equal to that of which he has been the cause return upon the agent. The one-sided deed of good or ill is a disturbance, the removal of which demands a corresponding requital.
Herbart warns us against the attempt to derive the five original Ideas (which scientific analysis alone separates, for in life we always judge according to all of them together) from a single higher Idea, maintaining that the demand for a common principle of morals is a prejudice. From the union of several beings into one person proceed five other pattern-concepts, the derived or social Ideas of the ethical institutions in which the primary Ideas are realized. These correspond to the primary Ideas in the reverse order: The system of rewards, which regulates punishment; the legal society, which hinders strife; the system of administration, aimed at the greatest possible good of all; the system of culture, aimed at the development of the greatest possible power and virtuosity; finally, as the highest, and that which unites the others in itself, society as a person, which, when it is provided with the necessary power, is termed the state.
