quick of slow, black of white, and these pairs are contraries, while they are neither good nor evil. 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.
