Whatever is is either evil or good or indifferent. We call that evil which is capable of invariably doing harm; for
Good order in the state falls under three heads. First, if the laws are good, we say that there is good government. Secondly, if the citizens obey the established laws, we also call this good government. Thirdly, if, without the aid of laws, the people manage their affairs well under the guidance of customs and institutions, we call this again good government. Thus three forms of good government may exist, (1) when the laws are good, (2) when the existing laws are obeyed, (3) when the people live under salutary customs and institutions.
Disorder in a state has three forms. The first arises when the laws affecting citizens and strangers are alike bad,
the second when the existing laws are not obeyed, and the third when there is no law at all. Thus the state is badly governed when the laws are bad or not obeyed, or lastly, when there is no law.
Contraries are divided into three species. For instance, we say that goods are contrary to evils, as justice to injustice, wisdom to folly, and the like. Again, evils are contrary to evils, prodigality is contrary to niggardliness, and to be unjustly tortured is the contrary of being justly tortured, and so with similar evils. Again, heavy is the contrary of light,
Thus, of contraries, some are opposed as goods to evils, others as evils to evils, and others, as things which are neither good nor evil, are opposed to one another.
There are three kinds of goods, those which can be exclusively possessed, those which can be shared with others, and those which simply exist. To the first division, namely, those which can be exclusively possessed, belong such things as justice and health. To the next belong all those which, though they cannot be exclusively possessed, can be shared with others. Thus we cannot possess the absolute good, but we can participate in it. The third division includes those goods the existence of which is necessary, though we can neither possess them exclusively nor participate in them. The mere existence of worth and justice is a good; and these things cannot be shared or had in exclusive possession, but must simply exist. Of goods, then, some are possessed exclusively, some shared, and others merely subsist.
Counsel is divided under three heads. One is taken from past time, one from the future, and the third from the present. That from past time consists of examples; for instance, what the Lacedaemonians suffered through trusting others. Counsel drawn from the present is to show, for instance, that the walls are weak, the men cowards, and the supplies running short. Counsel from the future is. for instance, to urge that we should not wrong the embassies by suspicions, lest the fair fame of Hellas be stained. Thus counsel is derived from the past, the present and the future.
