Financial exchange first involved bartering. However, with the difficulties of transmission between countries widely separated from each other, money as a currency arose. At first it was merely a specific amount of weighted or measured metal. Afterwards it received a stamp to mark the amount. Demand is the real standard of value. Currency, therefore, is merely a convention which represents the demand; it stands between the producer and the recipient and secures fairness. Usury is an unnatural and reprehensible use of money.
The communal ownership of wives and property as sketched by Plato in the Republic rests on a false conception of political society. For, the state is not a homogeneous unity, as Plato believed, but rather is made up of dissimilar elements. The classification of constitutions is based on the fact that government may be exercised either for the good of the governed or of the governing, and may be either concentrated in one person or shared by a few or by the many. There are thus three true forms of government: monarchy, aristocracy, and constitutional republic. The perverted forms of these are tyranny, oligarchy and democracy. The difference between the last two is not that democracy is a government of the many, and oligarchy of the few; instead, democracy is the state of the poor, and oligarchy of the rich. Considered in the abstract, these six states stand in the following order of preference: monarchy, aristocracy, constitutional republic, democracy, oligarchy, tyranny. But though with a perfect person monarchy would be the highest form of government, the absence of such people puts it practically out of consideration. Similarly, true aristocracy is hardly ever found in its uncorrupted form. It is in the constitution that the good person and the good citizen coincide. Ideal preferences aside, then, the constitutional republic is regarded as the best attainable form of government, especially as it secures that predominance of a large middle class, which is the chief basis of permanence in any state. With the spread of population, democracy is likely to become the general form of government.
Which is the best state is a question that cannot be directly answered. Different races are suited for different forms of government, and the question which meets the politician is not so much what is abstractly the best state, but what is the best state under existing circumstances. Generally, however, the best state will enable anyone to act in the best and live in the happiest manner. To serve this end the ideal state should be neither too great nor too small, but simply self-sufficient. It should occupy a favorable position towards land and sea and consist of citizens gifted with the spirit of the northern nations, and the intelligence of the Asiatic nations. It should further take particular care to exclude from government all those engaged in trade and commerce; "the best state will not make the "working man" a citizen; it should provide support religious worship; it should secure morality through the educational influences of law and early training. Law, for Aristotle, is the outward expression of the moral ideal without the bias of human feeling. It is thus no mere agreement or convention, but a moral force coextensive with all virtue. Since it is universal in its character, it requires modification and adaptation to particular circumstances through equity.
Education should be guided by legislation to make it correspond with the results of psychological analysis, and follow the gradual development of the bodily and mental faculties. Children should during their earliest years be carefully protected from all injurious associations, and be introduced to such amusements as will prepare them for the serious duties of life. Their literary education should begin in their seventh year, and continue to their twenty-first year. This period is divided into two courses of training, one from age seven to puberty, and the other from puberty to age twenty-one. Such education should not be left to private enterprise, but should be undertaken by the state. There are four main branches of education: reading and writing, Gymnastics, music, and painting. They should not be studied to achieve a specific aim, but in the liberal spirit which creates true freemen. Thus, for example, gymnastics should not be pursued by itself exclusively, or it will result in a harsh savage type of character. Painting must not be studied merely to prevent people from being cheated in pictures, but to make them attend to physical beauty. Music must not be studied merely for amusement, but for the moral influence which it exerts on the feelings. Indeed all true education is, as Plato saw, a training of our sympathies so that we may love and hate in a right manner.
- regarded life within a moral community as a vital component of human morality.
- social order is presumed by the general concept of justice
- Aristotle offered an account of distributive justice that made allowances for the social rectification of individual wrongs.
- The broader concept of political justice, however, is to be recognized only within the context of an entire society. Thus, it deserves separate treatment in a different treatise.
Aristotle also drew a sharper distinction between morality and politics than Plato had done. Although a good citizen is a good person, on Aristotle's view, the good person can be good even independently of the society. A good citizen, however, can exist only as a part of the social structure itself, so the state is in some sense prior to the citizen.
Depending upon the number of people involved in governing and the focus of their interests, Aristotle distinguished six kinds of social structure in three pairs:
A state with only one ruler is either a monarchy or a tyrrany;
A state with several rulers is either an aristocracy or an oligarchy; and
A state in which all rule is either a polity or a democracy.
In each pair, the first sort of state is one in which the rulers are concerned with the good of the state, while those of the second sort are those in which the rulers serve their own private interests.
Although he believed monarchy to be the best possible state in principle, Aristotle recognized that in practice it is liable to degenerate into the worst possible state, a tyrrany. He therefore recommended the formation of polity, or constitutional government, since its degenerate form is the least harmful of the bad kinds of government. As always, Aristotle defended the mean rather than run the risk of either extreme.
