摘要：Did Cicero intend his statesman to be understood as a 'new concept' (K. Büchner) when he called him tutor et procurator rei publicae and rector et gubernator civitatis (2.51)?Now numerous instances before and with Cicero of similar metaphors and their combinations applied to political activities make it quite clear that there is nothing new insofar as these phrases are concerned. So in view of their well-known metaphorical character 'minus......tritum sermone nostro' (2.51) should not be translated by 'not frequently used in our language i.e. Latin' but by 'not fully treated in our conversa-tion'.The study of the passages concerning the role of this statesman suggests too that it is chiefly based on auctoritas and is not appreciably different from that of the principes of the Roman republic. It is, however, very remarkable that the analogy of the reason swaying and controlling the mind, by which the imperium of a monarch is explained, seems also to have been used to describe the activities of this statesman (2.67ff.). Cicero, while conceding the superiority to the mixed form of constitution, maintains that monarchy is to be preferred to the other unmixed forms because of, among others, the fact that there will be no imperium at all unless it remains a unit. It could be inferred from this that what Cicero, when using this analogy, had in mind was a statesman who, while acting on auctoritas (2.69: ut sese......sicut speculum praebeat civibus), would be the sole leader in the state. This semi-monarchistic role is, however, clearly incompatible with the principles of the mixed form of constitution which Cicero pronounces the best and sees embodied in the Roman republic. This inconsistency, if it may be called so, could have resulted from his theorizing on an ideal statesman in line with Greek political theories while retaining him in the framework of the Roman republic.Now this statesman is set in opposition to a tyrant who is nothing but a deteriorated form of monarchy as is illustrated by the Roman history. This transformation of the best single form into the worst is most typical of all political changes. The mixed form, according to the Greek theories (mainly Polybios) outlined in the De re publica, is the most effective in maintaining equality and stability and thus preventing any change for the worse because it combines and balances the elements of the three unmixed forms; whereas Cicero sees the vital factor of stabilization in the statesman who cares for the practical interests and the self-respect of his fellow-citizens, foreseeing dangerous changes and taking necessary steps against them. Here Cicero, while following a familiar pattern of political discussions where a tyrant or tyranny is contrasted with a just king or other forms of constitution, reserves for his statesman a leading role in renewing and preserving the Roman state, and all who are present in the conversation are urged to become like him (2.45) since he is an exemplum (2.69), a model to be followed by all his fellow-citizens.The impression thus gained would be that of a 'new' statesman, but he remains nonetheless a traditional i. e. republican princeps, presented as he is in an idealized form. This method of theorizing on the traditional institutions (mos maiorum), idealizing and presenting them as exempla, is used again in the De legibus which was probably begun as soon as, or before, the De re publica was finished.It is not clear whether Augustus was influenced by Cicero's concept of this statesman. Granting that he adopted for his principate the latter's concept, then he pretended it was not new, for he emphasized his role in having restored the Roman republic and posed as a traditional princeps acting on auctoritas. In reality, however, his principate was nothing other than a kind of monarchy, a novus status, as Suetonius called it.
